Adria ready to make BEV statement with revamped charging platform

The emergence of Adria Power Systems’ latest charging solution is evidence of just how quickly the industry is adopting battery-electric vehicles underground and on surface, while highlighting an incoming interoperability issue the industry is likely to face.

The charger in question – a 1 MW bi-directional system with four bridgeable outputs – has been designed as part of a federal and provincial government electrification program centred around Nouveau Monde Graphite’s Matawinie project in Quebec, Canada.

The collaboration, involving the Innovative Vehicle Institute, Propulsion Québec, the National Research Council of Canada, Adria, Dana TM4, Fournier et fils and NMG, would result in the development of a new electric propulsion system with a rapid recharging infrastructure adapted to heavy vehicles in the open-pit mining industry.

For Adria’s part, it was tasked with creating a charging platform that could energise a battery-electric converted Western Star 6900XD truck with a 40 ton (36 t) loading capacity.

Jean-Francois Couillard, President of Adria, told IM that this charger, initially planned as an 800-kW model, would be used for a “slower and opportunity charging application” at Matawinie, with the site’s operating philosophy not requiring a fast charge solution.

While 800 kW and a slower/opportunity charging solution was all that was required, the company has outdone itself, developing a 1 MW model that, Adria says, can be used in a variety of applications in both underground and surface mining.

It is a step up from the CCS-type charger deployed at Alamos Gold’s Young-Davidson mine in 2020, which had two DC/AC outputs and offered Level 3 DC fast charging with a type 2 plug as recommended by the GMG BEV guideline.

Such a change required a revamped design philosophy, according to Couillard.

“Technically, when we started to plan for this prototype, we wanted to be conservative, but, down the road with the design work, we realised we could go to 1 MW with this same system,” he said.

This watt capacity is high when compared with other charging solutions to have recently hit the market.

Adria Power Systems’ new 1 MW charger comes with a state-of-the-art user interface that will allow user friendly use and status reporting, according to the company

The new Cat® MEC500 Mobile Equipment Charger, for instance, comes with a 500-kW capability able to charge its R1700 XE in less than 20 minutes (when using parallel charging units), while the Tritium RT175-S charger re-energising Miller Technology’s Relay utility vehicles at BHP Mitsubishi Alliance’s Broadmeadow mine in Queensland, Australia, comes with 175 kW of output and a stated battery charge time of as little as 20 minutes.

The flexibility of Adria’s new solution is greater than many chargers on the market too, with Couillard saying the charger could end up being used as a 1 MW solution where all four outputs are bridged together for an extremely fast charge, or where one LHD from one OEM is fast charged with a 500 kW input from two of the charger’s bridged outputs while two utility vehicles from two different manufacturers are plugged into the other vacant outputs, each taking 250 kW of charge.

“The four outputs are totally independent; you can charge with four different protocols to communicate with various batteries at the same time, and you can charge with different power levels at the same time,” Couillard said. “It really can adapt very easily to any situation.”

This is the ideal solution for an industry still transitioning to electrification, where different applications may require fast charge, battery swap, opportunity charging or some other option.

On top of this, Adria’s new charging platform can be connected directly to a mine site’s medium-voltage infrastructure. There is no need for them to acquire an additional transformer to step down/up the voltage, according to Couillard.

“There are no other accessories required, which brings a lot of savings to customers,” he said.

Couillard sees the 1 MW charger in question as proving sufficient to fast charge the new higher tonnage battery-electric vehicles coming onto the market – Sandvik’s upcoming 65 t BEV being a good example here – yet he anticipates future requirements to go beyond the 1 MW mark with the introduction of bigger trucks and larger electric fleets on surface and underground.

Adria is more than prepared for this.

“We expect the power needs to go higher, but there will be a technical limit at one point, probably driven by customer infrastructure,” he said. “If you talk about high power for fast charging, then you will have a very big peak on the network that will have to be compensated somehow.”

Even with this theoretical technical limit, Adria is currently engaged with one mining company on a 5 MW charging system for surface mining trucks.

While recognising this as a “good challenge” for Adria’s team, Couillard says the new charging platform has been designed to accommodate this scale and potential problems that may come with it.

“We know there are a lot more challenges coming up at these higher power levels, namely harmonics,” he said. “With a small number of smaller capacity chargers, you don’t really see a harmonics impact. By the time you get to using multiple chargers, it can be a really big problem.”

The draw of highly distorted currents and voltages caused by high harmonics levels can potentially cause additional power losses and failures in distribution transformers, feeders and some conventional loads, such as AC motors, according to industry reports. It can also lead to higher power consumption costs, according to Adria.

This issue is not something many battery charging companies and mine site operators are considering, according to Couillard.

“The four outputs are totally independent; you can charge with four different protocols to communicate with various batteries at the same time, and you can charge with different power levels at the same time,” Jean-Francois Couillard says

“You see a lot of studies right now that mention the ease of building a charger up to 100 kW capacity, but, when they get to a higher power, the management or mitigation of the harmonics becomes more problematic,” he said.

“This is an issue we have solved on our platform, making it easy to scale to a different power level while keeping the same efficiency and low harmonics.”

The 1 MW charger to be used at Matawinie could end up charging more than just the Western Star truck conversion, with Adria using standardised industry protocols that all OEMs can subscribe to.

Whether all OEMs will follow such protocols is up for debate, according to Couillard.

“Some OEMs see these proprietary charging infrastructure solutions as very strategic,” he said. “A lot of them know that if they sell their charger to a mining company, they can lock that mining company into using their equipment.

“That makes strategic sense from their perspective, but it doesn’t make sense for the mining customer. The mining customer needs to have maximum flexibility and be in control of their future if they are to adopt electrification across their fleet. They cannot tie themselves to one manufacturer for the lifetime of the mine.”

This interoperability issue is one the industry knows well given the ongoing struggle to access machine telemetry data to improve fleet efficiency and reduce downtime.

And, it should be remembered, these charging systems are not cheap, so the idea of having multiple proprietary chargers to energise a mixed fleet is not something mine operators will want to consider.

“I think the mine operators will put a lot of pressure on the OEMs to offer some standardised options, or make their machines compatible with alternative platforms,” Couillard predicted.

As the industry ponders this predicament, Adria is continuing its in-house testing of the 1 MW charger. With plans to finish this testing and the charger assembly early in 2022, and the current schedule at Matawinie requiring the arrival of the charger next year, Couillard is hoping to take advantage of that spare time to test the charger underground in real mine-site conditions.

“We have a couple of prospects already, but we’re open for solicitation,” he said. “Ideally, we would have a couple of 2-3 month mine site trials under our belt before the charger arrives at Matawinie.”

He concluded: “I can say with confidence that this is the most interesting offering on the market right now. We are looking forward to putting this charger into service and show the charging advancement to mining companies.”

Nouveau Monde files US patent for thermochemical purification anode tech

Energy minerals, Metallurgy, Mineral processing, Power supply for mines, , , , , , , , , , , ,

Nouveau Monde Graphite has submitted a patent application for its proprietary thermochemical purification technology to the US Patent and Trademark Office that could see it gain intellectual property over a “greener” and more sustainable alternative process to that currently used in the traditional anode material production.

Leveraging Québec’s abundant, clean and affordable hydropower, the company’s technology avoids using hydrofluoric acid in favour of high temperatures and the addition of chlor-based reagent, it says.

Tests in labs and at third-party facilities have already demonstrated the technology’s performance and the products’ high purity, reaching 99.95% and over, according to the company.

Its Phase 1 purification facilities are in the final stages of commissioning, prior to starting production, process optimisation and material qualification with potential customers. At the same time, Nouveau Monde is carrying out its definitive feasibility study for the Phase 2 plant in Bécancour, Quebec, Canada.

The company’s 200,000 sq.m industrial site, adjacent to the Phase 1 location, is intended to consolidate manufacturing facilities for the production of 42,000 t/y of lithium-ion battery anode material and 3,000 t/y of purified flakes for specialty applications. The plant will process material from the Matawinie mine.

In addition to energy applications, Nouveau Monde’s thermochemical process has shown to be effective at purifying larger particle sizes that are expected to allow the company to supply high-purity, carbon-neutral graphite flakes for bipolar plates used in fuel cells, foils for heat dissipation in electronics, expandable graphite for fire retardant applications and other specialty products, it said.

Arne H Frandsen, Chairman of Nouveau Monde, said: “Research and development is a critical component of our business model. The filing of this important patent application is a tangible manifestation of our commitment to sustainable development and the success Nouveau Monde has already achieved from its Center of Excellence in Québec.”

Eric Desaulniers, Founder, President and CEO of Nouveau Monde, added: “I believe there is much appetite in the marketplace for alternatives to China’s dominant chemical-heavy processes. We have developed a technology that takes full advantage of Québec’s green hydroelectric asset and operates in a closed loop with our chemical supplier to minimise the environmental footprint of our purified products. This patent application reiterates our engagement towards R&D, innovation, and environmental stewardship to drive greater sustainability into the battery value chain.”

Nouveau Monde Graphite turns to Metso Outotec for key Matawinie processing equipment

Nouveau Monde Graphite has launched civil construction works at its flagship Matawinie graphite mining project in Saint-Michel-des-Saints, Québec, having steadily advanced detailed engineering and engaged in the procurement of key service providers, long-lead equipment and contractors to deliver the project, billed as a “zero-emission mine”, in Québec by the end of 2023.

One of these service providers has been confirmed as Metso Outotec, which has been engaged to supply key mineral processing equipment required for the Matawinie concentrator plant for high-purity graphite flake production.

The agreement with the OEM will support the development of design and integration efficiencies through process equipment chain optimisation objectives, NMG said. It also seeks to promote planning efforts, optimisation of the project cost curve and support the company during the construction, commissioning and operation phases.

“This agreement complements Nouveau Monde’s de-risking strategy and helps ensure a rapid progression of final design elements and construction of the ore processing facility,” the company added.

Following the governmental authorisation of the project in February, Nouveau Monde executed its phased program to initiate preliminary works in March. For the site preparation of the mine industrial platform and the access road connecting the project to the local highway, tree clearing was completed before the nesting season to limit impacts to avifauna.

To protect the environment and the community’s well-being, Nouveau Monde has developed an environmental surveillance and monitoring program to oversee the construction, operation and closure activities of the Matawinie project. Nouveau Monde has hired an environmental coordinator to support construction and environmental monitoring activities on-site and enlisted third-party biologists to conduct inspections for the presence of vulnerable species.

Nouveau Monde is also delivering on its commitment to maximise local opportunities and support service providers by engaging with Atikamekw, local and regional contractors and service providers via dedicated activities related to its construction procurement strategy, the associated business opportunities, as well as health, environment and safety requirements for bidding.

The company has retained mining contractor L Fournier & Fils to build the access road connecting the main Highway 131 to Matawinie’s industrial platform. Works for the 7.8-km access road began in July as part of the company’s 30-month construction and commissioning timeline. Construction of the access road is scheduled to be completed in September 2021 to facilitate subsequent civil works and on-site activities.

Eric Desaulniers, President and CEO of Nouveau Monde, said: “This first milestone kick starts the construction of the Matawinie mine, as we strive to build the high-quality, ethical and sustainable project that can cater to the growing electric vehicle and energy storage markets. We have spent the past months refining our execution plan to carry out engineering, procurement and construction activities safely and with a focus on cost and timeline efficiency. I am confident in the expertise of the technical team that we have assembled, coupled with the support of Tier 1 service providers such as Metso Outotec, L Fournier & Fils and many local contractors, to deliver on our commitments of safety, responsible practices and excellence.”

In the 2018 definitive feasibility study on Matawinie, the mine, scheduled to produce 100,000 t/y of graphite concentrate, was expected to use an electric in-pit mobile crusher and overland conveyor system to feed crushed material to the plant.

Cat to use NMG’s Matawinie graphite mine as ‘zero-emission machine’ testbed

Nouveau Monde Graphite and Caterpillar have signed an agreement pursuant to which Caterpillar will develop, test and produce Cat® “zero-emission machines” for the Matawinie graphite mine, in Quebec, Canada, with a view to becoming the exclusive supplier of an all-electric mining fleet for deployment at the mine by 2028.

Looking to accelerate and tailor the equipment development, Caterpillar will engage with Nouveau Monde’s team to incorporate “voice of customer” throughout the development, and for testing of the zero-emission fleet and infrastructure prior to commercial production, the companies said.

To this point, Caterpillar has only disclosed the development of a battery-electric 15 t LHD, the R1700 XE, however it came to light just over a year ago that the OEM was working on a separate project called ‘Project Verde’.

Brian Weller, Chief Engineer, Surface Mining & Technology, Caterpillar Inc, previously stated on Project Verde: “Caterpillar has responded to customers by launching a project that is focused on energy and emissions reduction, and helping customers decrease their carbon footprints through machinery and power solutions that contribute to lower greenhouse gas.”

Speaking about the latest agreement between NMG and Cat, Arne H Frandsen, Chairman of Nouveau Monde, commented: “I recall our first meeting with Caterpillar some two years ago, outlining our vision of a zero-emission mine in Québec. Our commitment to this vision has taken us to this very important moment, not only for Nouveau Monde, but for the global mining industry as a whole. Today, alongside Caterpillar, which in my opinion is the most trusted and reputable supplier of heavy-mining equipment worldwide, we can bring the zero-emission machines vision into reality.

“I think it is remarkable that Nouveau Monde, as a representative for the new style green resources industry, is part of spearheading the electrification of the industry, by collaborating with Caterpillar.”

Eric Desaulniers, Founder, President and CEO of Nouveau Monde, added: “We are proud to be a driving force for our peers as we strive to electrify our operations to meet our carbon neutrality commitments while maintaining the productivity and efficiency standards of our mining operations. Even more gratifying and important to our corporate mission is that our project can serve as a springboard for the future of the mining industry by collaborating with Caterpillar on these cutting-edge technologies.”

Denise Johnson, Caterpillar Group President, said: “The collaboration between Caterpillar and Nouveau Monde marks an important milestone in the mining industry. Through integrated technology, machines and services, the entire Caterpillar team is proud to support Nouveau Monde as they work towards constructing and establishing their first zero-emission mine.”

In November last year, NMG issued an “international call for pre-qualification” related to the fleet and charging infrastructure at Matawinie following work by the company’s International Task Force Committee. This work had allowed Nouveau Monde to explore “technologies, best practices and operational parameters to bring its vision to life in a cost-effective and technologically advanced way”.

As part of this pre-qualification program, companies were able to submit detailed proposals and performance specifications from their production equipment solutions between November 30 and January 30, 2021.

In the 2018 definitive feasibility study on Matawinie, Medatech Engineering Services Ltd and ABB Inc – both companies in Nouveau Monde’s taskforce committee – came up with the fleet outline at Matawinie.

“The mine will be using an all-electric, zero-emission mine fleet, consisting of electric battery-driven 36.3-t mining trucks, battery-driven front-end loaders, cable reel excavators and bulldozers, and battery-driven service vehicles,” the report read.

The mine, scheduled to produce 100,000 t/y of graphite concentrate, was also expected to use an electric in-pit mobile crusher and overland conveyor system to feed crushed material to the plant.

Nouveau Monde receives provincial green light for Matawinie graphite mine build

Following a rigorous environmental review, the Québec Government has issued a ministerial decree authorising Nouveau Monde Graphite Inc’s Matawinie mining project for a 100,000 t/y high-purity graphite concentrate production.

Located only 150 km north of Montréal, the company’s deposit constitutes the largest projected graphite operation in North America and Europe and is expected to become the world’s first all-electric open-pit mine, Nouveau Monde says.

“Since filing its bankable feasibility study, Nouveau Monde has invested time and effort to meticulously plan mining and environmental engineering, master the ore metallurgical process to reach 97% purity after simple flotation, de-risk its operation through its demonstration plant, and actively engage with the local community of St-Michel-des-Saints to secure a social licence to operate and with the Atikamekw First Nation,” the company said.

The environmental decree now provides Nouveau Monde with the operational criteria and final design parameters to launch construction activities.

It plans to start early works at the mining site as of the June quarter, and full construction is expected to be launched in the September quarter once permits and authorisations are finalised. The project timeline places commissioning activities and start-up of commercial production in 2023.

Arne H Frandsen, Chairman of Nouveau Monde, said: “Today’s milestone is something we have worked towards as a team since the outset in 2011. After a decade of meticulous planning, we can now commence the mine construction of our world-class Matawinie graphite project. We are most grateful for the continued support Nouveau Monde has received from the Québec Government and our partnership with Investissement Québec as well as the backing from our local host communities – all being important stakeholders of this success.

“We will exercise our mandate in the spirit of cooperation, sustainability and benefit sharing for all parties involved. The creation of the Western World’s largest anode-quality graphite mine will assist positioning Québec as the prime location for the North American battery materials hub – supplying the continent with the critical anode and cathode materials required for the batteries needed for the global electrification of mobility.”

Eric Desaulniers, President and CEO of Nouveau Monde, added: “With this green light to launch our Matawinie project, we plan to bring to market a responsibly extracted high-purity graphite to supply electric vehicles and energy storage sectors with a local and sustainable alternative. Doing so will position Nouveau Monde as a leading anode material provider for decades to come, creating opportunities and unlocking value for all parties involved.”

Nouveau Monde is working towards developing an operation that can provide the volumes required by major auto original equipment manufacturers and battery manufacturers; the most recent estimates indicate 120.3 Mt combined measured and indicated resources at a 4.26% Cg grade. Geological knowledge of the Matawinie property, paired with experience in extracting and concentrating the ore at the company’s demonstration plant, have significantly de-risked the project.

Nouveau Monde has also integrated forward looking and innovative environmental initiatives to limit the project’s footprint and protect local biodiversity, namely:

  • Integrated onsite water management system guaranteeing constant monitoring and treatment that meet the highest quality standards;
  • Co-disposal of tailings and waste rock in line with requirements of the best practices such as The Global Tailings Review, the International Network for Acid Prevention and the Canadian Mine Environment Neutral Drainage Program. This management solution helps avoid acid mine drainage, provides greater environmental safety in the long term and reduces the infrastructure’s footprint;
  • Progressive land reclamation through backfilling of the pit and a comprehensive restoration plan; and
  • An all-electric fleet – a world’s first for an open-pit mine – powered by Québec’s clean, abundant, and affordable hydroelectricity.

Through its demonstration operations, Nouveau Monde has already validated its process for desulphurisation of tailings and completed the construction of a co-disposal experimental cell through a collaborative partnership with Université du Québec en Abitibi-Témiscamingue.

Over the life of mine, the company intends to implement this system through a co-disposal pile and backfilling of the pit as of year six, promoting thereby the restoration of the natural ecosystem while reducing environmental risks. To ensure long-term sustainability, the co-disposal storage facility will also include a capillary barrier effect multi-layer cover to block oxygen and vegetate the site.

SNC-Lavalin, Lamont Expert, Minesite Drainage Assessment Group and the National Research Council (NRC) of Canada have conducted modelling analysis of Nouveau Monde’s co-disposal design to study critical design parameters on sulphide oxidation reaction rates and optimise configurations of the pit backfill and co-disposal pile.

Recently the company has expanded the mandate of NRC to simulate additional site-specific pile design parameters, like compaction level, using Nouveau Monde’s demonstration plant tailings and test cell results. NRC will expand the model developed in earlier phases and provide the company with a strong tool to optimise tailings deposition plans.

Nouveau Monde Graphite casts net out for carbon-neutral, zero-emission fleet

Nouveau Monde is putting out a call to arms across the technology space for its Matawinie graphite project, in Quebec, Canada.

The company, which has been pushing forward development of an all-electric open-pit mine in the province, has issued an “international call for pre-qualification” related to the fleet and charging infrastructure at the project.

Since October 2018 when the company issued a definitive feasibility study (DFS) on the West Zone of the Matawinie deposit, the mining industry and the technology space that serves it have undergone huge change.

Hydrogen is no longer a pipe dream, with hybrid vehicle development already set in motion across the globe; while the types of electric solutions being offered by OEMs has evolved with new types of trolley and cable-electric solutions, plus more powerful and reliable battery technologies.

This has led to some of the assumptions made around 25 months ago being re-evaluated.

The call for pre-qualification follows work by the company’s International Task Force Committee, which has allowed Nouveau Monde to explore “technologies, best practices and operational parameters to bring its vision to life in a cost-effective and technologically advanced way”.

The company added: “Discussions with manufacturers have already enabled to identify existing machinery in development and/or available, notably the ancillary fleet where purchasing agreements are being finalised.”

David Lyon, Director Electrification and Automation at the company, provided a bit more background to the announcement.

“We’re not actually that far out from production at Matawinie; come January, we’ll be around two years away from producing at the site,” he told IM. “Over that time, we’ve done a lot of due diligence and homework, including the pilot graphite anode project.

“We now have a pretty good roadmap towards electrifying the mine, but our view has changed a little bit. We’re not just saying it is going to be electrified anymore; we’re saying it will be carbon neutral and produce zero tail pipe emissions.”

Lyon added: “We’re afraid we haven’t turned over every rock in the technology sphere and we want companies – not just the ones we have already got in contact with – to come to us with ideas.”

That change in tone has been aided by Air Liquide’s plans to build a hydrogen electrolyser in Bécancour, very close to the company’s planned anode plant. This could produce 3,000 t/y of hydrogen from renewable energy sources.

“Having a green supply of hydrogen just down the road, and less than 200 km from the mine site, is opening up the opportunity for fuel cells, as well,” Lyon said.

While hydrogen power could provide an environmentally friendly power supply for stationary plant, there is also the potential for it serving the loading and haulage side of the mine, as indicated in today’s announcement: “Whether powered by lithium-ion batteries, plug-in systems or hydrogen fuel cells, Nouveau Monde is seeking the best zero-emission equipment for heavy-duty operations and harsh conditions associated with open-pit mining.”

Lyon added to this: “The call is for our entire mining fleet – any piece of the puzzle – to open it up to manufacturers that maybe we have missed along the way. There is a lot of good technology being developed across the globe and it would be a shame to go into full procurement mode without at least allowing those companies to participate in the process.”

Large OEMs and innovative SMEs, alike, will be able to submit detailed proposals and performance specifications from their production equipment solutions between November 30 and January 30, 2021, the company said.

In the 2018 DFS, Medatech Engineering Services Ltd and ABB Inc – both companies in Nouveau Monde’s taskforce committee – came up with the fleet outline at Matawinie.

“The mine will be using an all-electric, zero-emission mine fleet, consisting of electric battery-driven 36.3-t mining trucks, battery-driven front-end loaders, cable reel excavators and bulldozers, and battery-driven service vehicles,” the report read.

The mine, scheduled to produce 100,000 t/y of graphite concentrate, was also expected to use an electric in-pit mobile crusher and overland conveyor system to feed crushed material to the plant.

Recently, the company has made headway on filling some of these requirements.

It signed a deal with Adria Power Systems, Dana TM4 and Fournier et fils – through the Innovative Vehicle Institute (IVI), Propulsion Québec and the National Research Council of Canada (NRC) – that would see a new electric propulsion system developed with a rapid recharging infrastructure adapted to heavy vehicles in the open-pit mining industry.

This would also see mining contractor Fournier et Fils provide the project with a battery-powered Western Star 6900XD truck with a 36 t loading capacity that is expected to make its first real-world test runs as early as spring 2022 at a Fournier et Fils quarry, and at the Nouveau Monde Graphite site.

Such developments are representative of the government support Nouveau Monde has received – both at a federal and provincial level – and the company is hoping this assistance encourages more companies to submit zero-emission options.

“Quebec, Canada, features renowned environmental standards, innovative talents, business-forward policies and virtually unlimited hydropower, making it an ideal playground for OEMs to build and deploy their electric solutions,” it said.

Still, NMG will not be able to fill all its haulage gaps through innovative prototype development.

Lyon said: “A commercially-supported solution over the 26-year mine life is really what we want. They exist, and we just need to properly quantify all those other solutions and put them in the queue for an open procurement call.”

And, according to Lyon, there is some flexibility to the payloads and requirements outlined in that 2018 DFS document.

“While we have found solutions in those classes today…we are still a bit flexible and open to looking at the upper and lower bands in terms of equipment,” he said.

This can be seen in the full call for pre-qualification, which includes two 90 t excavators, one 50 t excavator, one 50 t wheel loader, 8-14 haul trucks with 50-65 t payloads, two drills, two 42 t dozers, two 22 t dozers, two 14M or 140 graders, two water trucks, and a range of operation and maintenance support machines. It adds up to a mining fleet including some 60 vehicles.

Flexibility on behalf of the vendors could also prove key in the company fulfilling its requirements.

“There isn’t today one supplier that is going to supply our whole fleet, and it is very important that these solutions work together,” Lyon said. “Maybe one of these suppliers has a comparable solution that matches well with other technology we are not aware of. That could make an impact on our planning.”

Lyon admits more than two years seems a long time to fill a fleet order, but he is cognisant that timeline is not as generous when considering much of it involves the use of new technology.

All this means there will be a transition to the carbon-neutral, zero-emission fleet after initial production starts up in 2023 at Matawinie. The company is putting this transition period at five years, hoping to have a fully-electric fleet by 2028.

Still, considering the 25.5-year life at Matawinie, most mining will be conducted in the mean and ‘green’ fashion Nouveau Monde’s stakeholders and wider industry are expecting.

“Nouveau Monde is proud to be acting as an enabler into the zero-emission heavy-duty operations and is welcoming any industrial operators in mining, quarry and/or construction sectors to reach out to its technical team with questions and interest,” the company concluded.

MEDATech speeds up battery-electric mining charge

The potential for electric drivetrain specialist MEDATech Engineering Services to add another high-profile client to its list of mining company references is high given the developments the Collingwood-based company is currently working on.

Having helped Goldcorp (now Newmont) and several OEMs realise their vision of an all-electric mine at Borden, in Ontario, MEDATech is energising more electrification projects with its ALTDRIVE system.

The company has been developing electrification technology for heavy-duty, off-highway vehicles for about six years. Its current drive train technology, MEDATech says, is capable of being scaled for most heavy haul applications in mining and other industries.

These last six years have seen it help fellow Collingwood resident MacLean Engineering convert underground roof bolters, graders, water trucks and many other production support vehicles for Canada’s underground mining sector. MEDATech has also helped Torex Gold and its Chairman, Fred Stanford, develop the necessary equipment to take the Muckahi all-electric underground mining concept to testing phase. Similarly, it has played a role in Nouveau Monde Graphite’s all-electric open-pit mine vision as part of a Task Force Committee developing studies for the Matawinie project, in Quebec.

Aside from the Muckahi project, the ALTDRIVE system, having been engineered to replace internal combustion engines, has been the driving force behind this work, according to Jeff Taylor, Managing Director of MEDATech Engineering.

The powertrain consist of a hybrid, or completely electric means of propelling the machine with industrial batteries, and can be adapted to heavy equipment such as commercial trucks, tractors, excavators, buses, haul trucks, light rail and – most important in this context – mining vehicles.

ALTDRIVE leverages battery systems from Akasol and XALT, chargers and power electronics from Bel Power Solutions and Dana TM4’s electric motors. The balance of the power electronics, control systems and sub systems, thermo management systems, VMU (a software component critical to the power management of the battery, electric motor charging and regenerative capabilities), and integration engineering is developed by MEDATech.

Taylor says it is the battery chemistry and charging philosophy of the ALTDRIVE technology that differentiates it from others on the market.

“The battery chemistry is really quite advanced and is all based on the future of fast charging,” he told IM. “In this scenario, we don’t want the batteries to be brought down to a high depth of discharge (DOD). We instead want operators to carry out quick, opportunity charging on the go.”

Most of the machines the company has been involved in manufacturing to date have been equipped with 25-100 kW on-board chargers, yet Taylor thinks its new breed of fast-charge battery-electric solutions could eventually require up to 1 MW of power and be charged through an automated system.

Such powerful charging systems may be the future of MEDATech’s ALTDRIVE drivetrain technology, but for now it is focused on leveraging the system for the conversion of a diesel-powered Western Star 4900 XD truck (pictured).

Part of a collaborative project with a Western Star dealer in Quebec where the dealer (Tardif) has donated the truck and MEDATech has provided its materials and engineering expertise, the truck is equipped with a 100 kW capacity on-board charger, 310 kWh of battery capacity, loaded gross vehicle weight of 40,824 kg and 25% more horsepower than its diesel-powered equivalent.

Loaded, the truck can cover 85 km (0% grade) on a single charge (80% DOD). This vehicle is ideal as a pit master unit for short run material moving, road maintenance, water hauling/spraying and snow plowing activities, according to the company. The truck can be on-board charged (2.5 hours) and fast charged (1 hour) during idle periods (at 80% DOD).

The machine will be ready for demonstrations at a gravel pit around 15 km away from the company’s Collingwood headquarters in September, and it has already caught the attention of some major miners.

According to Taylor, Anglo American (Chile), Teck Resources (British Columbia) and Vale (Ontario) are scheduled to see the BEV 4900 XD unit in September at the Collingwood facility. “Each company is looking at an electric machine(s) for their operations,” he said. “They might end up with a different truck, built to their exact specifications, but they want to test this machine out to experience a battery-electric conversion.”

After the 24 t payload truck, the company has eyes on converting a 40 t payload Western Star 6900 XD diesel truck to battery-electric mode.

“This will just be a bigger conversion on a bigger truck,” Taylor explained. “We’ll have extra room on the truck for placing batteries and the extra motor that will be required. It will also be an all-wheel drive vehicle, as opposed to the real-wheel drive of the 4900 XD, which will need some extra engineering.”

While Taylor said work on converting this 40 t machine would not start until the all-electric 4900 XD had been tested, he saw plenty of opportunities for scaling up and down the ALTDRIVE technology to create more customised ‘green’ vehicles for the mining industry.

“If you look at any mine site in Canada, there are five or 10 vehicles you could replace with electric versions,” he said.

Nouveau Monde Graphite says it has mandated Hydro-Québec to carry out a preliminary project encompassing the development, installation and operation of a 120 kV electrical line that will supply its Matawinie mine site and help the company meet its carbon-neutrality targets.

The goal is to connect the Matawinie project mine and concentrator, in Quebec, Canada, to the power network via a dedicated line that will enable the full electrification of its operations – a world first for an open-pit mine, according to NMG.

During the design phase, the technical, financial and environmental aspects, as well as the construction schedule, will be defined for the line. Hydro-Québec, Canada’s largest electricity producer and one of the world’s largest producers of hydroelectricity, will begin its studies and then issue public communications about the project in the coming months. The 120 kV line is expected to be powered up for the start of the mine’s operations in 2022, NMG said.

NMG said: “With its dedication to stringent sustainable development standards, Nouveau Monde is committed to having both its heavy equipment used for mining operations and its ore concentration and processing activities become fully electric within the first five years of production.”

The planned electrical line will supply power to support this operating model, which will reduce the CO2 emissions of the mine by more than 300,000 t over its lifetime, the company added.

Eric Desaulniers, President and CEO of Nouveau Monde, said: “The preliminary project is an important step in our electrification strategy, as the power line will guarantee a reliable, affordable and dedicated supply of renewable energy. This will give us a competitive advantage that lets us bring to market a product with the smallest possible environmental footprint.”

Desaulniers added that the company is having “positive discussions with commercial partners” to develop an electric fleet that is adapted to its property’s open-pit mining conditions.

The detailed engineering work is progressing in line with these goals.

“From mine planning to shift scheduling that takes into account recharge cycles, Nouveau Monde and its consultants are reinventing industry conventions to create the mine of the future,” it said.

NMG and Hydro-Québec have already partnered to research and develop graphite anode materials used to make lithium-ion batteries. The graphite developer also holds an operating licence from Hydro-Québec’s Center of Excellence in Transportation Electrification and Energy Storage to commercialise battery material technologies and position Quebec in the lithium-ion battery value chain.

Matawinie, in Saint-Michel-des-Saints, Quebec, is expected to start up in 2022. A 2018 feasibility study revealed strong economics for the project, with projected high-quality graphite concentrate of 100,000 t/y over a 26-year period.

Nouveau Monde Graphite to add Tesla Cybertrucks to all-electric fleet at Matawinie

Nouveau Monde Graphite, which is attempting to develop the world’s first all-electric graphite mine at Matawinie in Quebec, Canada, says it has placed an order for five new Tesla Cybertrucks.

The announcement came in the same week Tesla’s Elon Musk unveiled the new all-electric vehicles at an event in the US.

In a post on LinkedIn, NMG said: “As we advance our mining development and business model targeting the lithium-ion batteries market, we felt these new Tesla Cybertrucks would be the perfect addition to our fleet.”

Likely to be used at Matawinie as a personnel carrier/utility vehicle, the Cybertruck is built with an exterior shell made for “ultimate durability and passenger protection”, according to Tesla. It has a “nearly impenetrable” exoskeleton, with Ultra-Hard 30X Cold-Rolled stainless-steel structural skin, in addition to Tesla armour glass. It also has an estimated plus-250 mile range, the company said.

It also has up to 3,500 Ib (1.6 t) of payload capacity and adjustable air suspension, 2.8 cu.m of exterior, lockable storage; a towing capability of over 14,000 Ib (6.4 t); adaptable suspension and self-levelling capabilities, Tesla says.

The truck can seat six “comfortably”, comes equipped with a 17 in touchscreen and all-new customised user interface, in addition to both on-board power and compressed air, according to the company.

Matawinie, meanwhile, is expected to start up in 2022. A 2018 feasibility study revealed strong economics for the project, with projected high-quality graphite concentrate production level of 100,000 t/y over a 26-year period.

SNC-Lavalin to lead on engineering, procurement for NMG’s graphite plant build

Nouveau Monde Graphite has awarded SNC-Lavalin, in partnership with Seneca and Boucher-Lachance Architects, the contract for detailed engineering and procurement services for the construction of its concentrator as part of its Matawinie graphite project, in Quebec, Canada.

Engineering work is already underway to complete priority activities by the end of the December quarter of 2019, including the process review, a Class 2 estimate, and a risk and opportunity assessment to optimise infrastructure design and generate savings, NMG said.

In 2015, Nouveau Monde discovered a graphite deposit on its Matawinie property, located in Saint-Michel-des-Saints, 150 km north of Montréal. It completed a feasibility study in 2018, which revealed strong economics with projected high-quality graphite concentrate production level of 100,000 t/y over a 26-year period.

Eric Desaulniers, President and CEO of Nouveau Monde, said: “With an impressive track record in concentrator design, procurement and project management in Quebec, the selected firms will facilitate the commissioning of commercial operations to supply the market with high-quality graphite.”

The entire project will be carried out in virtual design & construction (VDC), enabling integrated and dynamic modelling of the building information modelling (BIM) engineering for the concentrator, according to NMG.

“This innovative platform will facilitate the transfer from engineering to construction and then to operation,” the company added.

NMG’s master team, part of the management team and composed of senior specialists with several decades of experience each, will act as experts to validate the engineering, the procurement strategy and the technical specifications for the equipment, it said.

The engineering work will also take advantage of process optimisations identified at the Matawinie demonstration plant (pictured), which has been operational for one year. With a few hundred tonnes of graphite concentrate produced to date, the operation has demonstrated exceptional ore quality and a high-performance process to achieve a graphite purity of 97% on average and up to 99% for the largest flakes, according to NMG.

Nouveau Monde leverages this production, which is segregated into several granulometric categories ranging from flakes of more than 0.3 mm (+50 mesh) to the finest products of less than 0.1 mm (-150 mesh), to supply potential customers with samples so they can test the concentrate and confirm their commercial intentions. The demonstration plant will also be the preferred training platform for future Nouveau Monde employees to accelerate the start-up of operations thanks to process knowledge and hands-on experience with similar equipment.

Desaulniers concluded: “Nouveau Monde’s mining project has really taken off in recent months now that we have a solid foundation for our Matawinie graphite project. Our demonstration plant has validated the effectiveness of our treatment process, which is now being optimised by our team of experts in anticipation of the commercial plant. Next year promises more achievements as we complete the design of our operation, reserve key equipment and crystallise our customer base.”
