Vale Energy Transition Metals, a leading global supplier of nickel, copper, cobalt and platinum group metals, says it is moving to accelerate commercial recovery of critical minerals from mine waste in partnership with the Mining Innovation, Rehabilitation, and Applied Research
Corporation (MIRARCO) at Laurentian University, in Canada.

As part of efforts to reduce mine waste and capture additional value from mined material, Vale has committed C$875,000 ($635,769) over five years to MIRARCO to support a new industrial research chair program in biomining and bioremediation. The announcement was made during the Prospectors & Developers Association of Canada 2023 Convention, in Toronto, Canada.

The industrial research chair program, led by Dr Nadia Mykytczuk (pictured in the centre), will develop, pilot and work towards commercialising bioleaching and bioremediation processes including efforts to recover nickel and cobalt from low-grade pyrrhotite tailings and other waste.

Luke Mahony, Chief Technical Officer at Vale Energy Transition Metals (pictured second from left), said: “This builds on our extensive R&D history and proven track record of lab-to-plant process development and represents a significant opportunity for waste-stream reprocessing here in Ontario. We see this as a triple-win, with potential to reduce liabilities, accelerate commercial recovery of critical minerals and capture additional value from mined material.”

The Government of Ontario will also contribute C$750,000 through the Northern Ontario Heritage Fund Corp. to support this industrial research chair program.

Greg Rickford, Minister of Northern Development (pictured second from right), said: “The new and improved Northern Ontario Heritage Fund Corporation is supporting innovative solutions in the resource extraction sector that will change the way we see mining traditionally. By partnering with Vale and Laurentian University, we are committing to Made in Ontario solutions that will reduce mine waste and enhance value for materials already involved in the mining process.”

Dr Mykytczuk, President and CEO of MIRARCO, said: “This funding and collaboration will accelerate the development of new tools to help us extract value from wastes, producing the metals we need in an environmentally sustainable way.”

Vale Energy Transition Metals is one of the world’s largest producers of high-quality nickel and an important producer of copper and responsibly sourced cobalt. With headquarters in Toronto, Canada, and operations in Newfoundland & Labrador, Ontario, Manitoba, Indonesia and Brazil, the business delivers critical building blocks for a cleaner, greener future.

Canada Nickel progresses carbon capture and storage test work for Crawford

Base metals, Environmental, Mineral project development, Sustainable mining, , , , , , , , , , , , , , ,

Canada Nickel Company Inc says the latest test work on material from its Crawford project, in Ontario, Canada, supports the incorporation of carbon capture and storage into the develoment.

The company has devised an In-Process Tailings (IPT) Carbonation process, which, it says, is a novel method for accelerated carbon capture and storage that it believes has transformative potential.

The latest test work conducted at Kingston Process Metallurgy (KPM) confirmed that existing process streams can be used for IPT Carbonation, which the company believes should allow it to be timely and cost effectively engineered and incorporated into the project flowsheet.

Crawford is hosted in ultramafic rock, which naturally absorbs and sequesters CO2, according to the company, with the potential to actively capture and sequester carbon being a key consideration in Canada Nickel’s acquisition of the 42 sq.km of target ultramafic rocks in the Timmins area.

Canada Nickel has developed an active process that uses tailings as generated in the milling process and injects a concentrated source of CO2 for a brief period of time. This process, IPT Carbonation, fixes CO2 geologically while the tailings are still in the processing circuit, rather than after they have been finally deposited.

The company believes that, given its relative simplicity, this process could be scaled up with availability of concentrated (rather than atmospheric) sources of CO2, with the CO2 potentially delivered by downstream processing of Crawford concentrates, a wide range of industrial processing activities, green hydrogen production, or carbon capture facilities.

Canada Nickel said: “The process demonstrates the potential to produce NetZero Nickel™ and NetZero Cobalt™ for the electric vehicle industry, NetZero Iron™ and chromium for the stainless steel industry and generate substantial carbon credits during the process. The company believes that the need for a concentrated source of CO2 for this process and the substantial CO2 capture and storage capacity potential of its ultramafic land position could form the basis for an entire Zero Carbon Industrial Cluster in the Timmins-Cochrane region.”

The latest results from further lab-scale testing at KPM confirmed that a blend of tailings expected to be produced by Crawford and thickened to an expected operating tailings density could be successfully carbonated with the IPT Carbonation process, the company said. This is a significant result to demonstrate the process at higher solids densities as the pulp density and the tailings residence time will be a key driver of the process capital and operating costs, it explained.

The testing also attempted to understand what ultimate carbon capture potential is possible and the test resulted in 37 t of CO2 captured per tonne of nickel – 34 t of that amount was captured within 25 hours. The 37 t figure is believed to represent a potential maximum and there is no certainty that such amount could be achieved in commercial operation, the company said.

As a result of these results, the integrated feasibility study for the project is expected to be delivered in the June quarter of 2023. This delay, the company says, has no impact on the overall timeline to production, with Canada Nickel continuing to target receipt of permits by mid-2025 with construction to follow.

Mark Selby, Chair and CEO of Canada Nickel, said: “We believe the Crawford project has the potential to be a case study in how critical minerals are developed in Ontario and Canada. Crawford is poised to support the energy transition through the large-scale production of critical minerals, including nickel and cobalt, and to become the sole North American producer of chromium, while also supporting the country’s climate objectives through large-scale carbon capture and storage.”

The company believes the successful incorporation of IPT Carbonation could also potentially allow a portion of its project capital expenditures to become eligible for the carbon capture and storage refundable investment tax credits of 37.5% to 60% from 2022-30 and 18.75% to 30% from 2031-40 announced in the 2022 federal budget documents in Canada.

Selby added: “We look forward to continuing our positive momentum in 2023 as we complete this integrated feasibility study for Crawford, continue to successfully advance the Crawford permitting process, work with our recently appointed financial advisors to advance its overall financing package and aggressively advance our recently acquired Texmont property with its potential for near-term production. We are also excited by our successful tests of the regional exploration potential at Reid, Deloro, Sothman and Reaume which, as they are hosted in the same mineralisation as Crawford, offer the same potential for integrated carbon capture and storage – setting the stage for a Zero Carbon Industrial Cluster in the Timmins-Cochrane region.”

JP Morgan-backed financing paves way for further MineSense growth

Base metals, Environmental, Mining equipment, Mining finance, Mining services, Mining software, Sustainable mining, , , , , , , , , , , ,

MineSense Technologies Ltd says it has closed a $42 million Series E financing led by J.P. Morgan Asset Management’s Sustainable Growth Equity team that, it says, will allow it to accelerate the commercial deployment of its solutions to drive further growth and profitability.

The funding round includes participation from new investor Evok Innovations, a climate technology and sustainability venture fund, and existing investors including Prelude Ventures, BDC Industrial Innovation Venture Fund, Cycle Capital and Chrysalix Venture Capital.

MineSense has been pioneering data-driven solutions that improve ore grade control, operational profitability and carbon intensity across the metals mining industry. It is doing this through a combination of its ShovelSense® and BeltSense® hardware, a digital platform and geoscientific insight that goes beyond purely grade-based orebody information.

ShovelSense provides precise ore/waste definition and unlocks unique, previously inaccessible data sets at the mine’s extraction face, according to the company. This real-time data enables removal of waste from ore and recovers valuable ore from waste by making smart routing decisions that also reduces the amount of waste processed, production of tailings, and energy, water, and reagent consumption. Metal recovery is increased materially, with production from operating mines increasing by 5-25% on existing infrastructure, according to the company.

The company has initially been focused on copper, with those mining companies that have signed up to use its solutions looking to maximise ore recovery, minimise dilution and enhance operational sustainability.

MineSense says it has tripled revenue over the last year, and was recently recognised as one of the fastest growing companies in North America by Deloitte.

It currently currently serves mines across North and South America, with notable deployments in British Columbia (Teck’s Highland Valley Copper, Copper Mountain Mining’s operation and Taseko Mines’ Gibraltar operation), Chile (Carmen de Andacollo) and Peru (Antamina).

The fundraising will allow the company to expand its coverage globally and extend into other critical metals such as nickel, cobalt, zinc and iron, it said.

Jeff More, CEO of MineSense, said: “We are pleased to partner with J.P. Morgan Sustainable Growth Equity and Evok to scale our ore grade data mining solutions. This funding and strategic support will allow us to continue executing on our strategy of delivering profit enhancement, operational efficiency, and carbon intensity reduction to critical mining operations.”

Draslovka about to move into glycine leaching mining demonstration phase

Base metals, Environmental, Metallurgy, Mineral processing, Mining events, Mining services, Precious metals, Sustainable mining, , , , , , , , , , , , , , ,

Czech Republic-based Draslovka Holding is heading into a busy 12-month period where its glycine leaching technology will be showcased at numerous mining projects across the globe, the company told IM on the side lines of the Resourcing Tomorrow conference, in London, this week.

According to Ivor Bryan, Director of Mining Innovation at Draslovka Mining Solutions and the former MD of Mining & Process Solutions (MPS), the entity responsible for the development of the GlyCat™ and GlyLeach™ technologies, the company is embarking on around 10 projects in the mining space, which will prove up the 3,500 hours of testing that has been conducted at MPS’ facilities in Perth, Western Australia.

MPS was acquired by Draslovka, a major sodium cyanide producer in 2022, with the aim of the transaction being to grow and develop the glycine leaching business.

Gold leach testing via GlyCat has been the major area of focus over the last decade. The process was invented to reduce cyanide consumption while maintaining gold recovery for gold ores from deposits containing nuisance copper. It has been designed to enhance the dissolution of gold and copper in gold/copper ores where glycine is used as a catalyst with cyanide in a cyanide-starved leaching environment. It doesn’t replace cyanide, but, in fact, enhances its leaching capabilities by dealing with the high-cyanide consuming copper within these gold-copper orebodies.

Yet, the company is also now starting to make inroads into the base metal space through GlyLeach, with nickel and cobalt two specific areas of interest. The technology is able to leach the targeted metals with enhanced selectivity compared with conventional methods. It will solubilise copper, nickel, cobalt and zinc, while gangue minerals such as iron, manganese, silicates and carbonates remain in the leach residue, Draslovka says.

This is allowing the company to promote that it can reduce the capital expenditure associated with processing these metals by removing the need for smelting, or in the case of tailings deposits, helping recover metal from assets previously written off as ‘waste’.

While the technology could have applications at run of mine operations, Bryan and his colleague Jackson Briggs, Corporate Development Manager of Draslovka, believe the most immediate opportunity is in tailings where the application of glycine leaching on ‘waste’ material could recover valuable metals while reducing the potential liabilities associated with such storage facilities.

Of the 10 or so projects the company has ahead of it, one is situated in Western Australia where the company is looking to recover nickel and cobalt metals from a tailings deposit of a major mining company.

Another project – much closer to fruition – is in Chile and involves leaching a carbonate-hosted copper oxide deposit containing some 600 t of material.

In both cases, the company is looking to demonstrate that it can recover valuable metals at high recovery rates, with low impact – namely rationalising reagent and water use and, in the case of nickel-cobalt, removing smelting from the equation.

This, according to Draslovka CEO, Pavel Bruzek, is a “win-win” for mining companies and their stakeholders, benefitting both the balance sheet and the operational environmental footprint.

“While we are a major sodium cyanide producer, when we saw the potential of MPS’ glycine leaching technology and the increase in metallurgical complexity of orebodies looking to be exploited, it made perfect sense to work with and promote this technology,” he told IM. “It is the responsible thing to do for the industry.”

Glencore has signed a three-year contract extension with Wallis Drilling to retain the drilling company’s services at Murrin Murrin in Western Australia’s Goldfields region, which will extend Wallis’ long-standing relationship at the Glencore-owned operation to over a quarter of a century, the service provider says.

Wallis Drilling is a local Western Australian business, founded in 1965 by Marty and Jamie Wallis, which has grown to over 300 employees, but remains a family run business today.

Wallis has provided services to Glencore’s Murrin Murrin operation for 24 years and the contract extension, running through to September 2025, will see Wallis Drilling continue to provide RC grade control and blasthole drilling at Murrin Murrin.

Murrin Murrin is a nickel-cobalt mining and processing operation between Leonora and Laverton in the north-eastern Goldfields region of Western Australia and currently provides work for over 1,000 employees and contractors.

Wallis Drilling Manager, Wayne Waters, oversees the Murrin Murrin contract, with his role previously being occupied by Grant Wallis who is now the Chief Operating Officer of the business.

Waters said: “Murrin Murrin, like Wallis, understands the importance of establishing and nurturing long-term relationships to create stability, which has been exemplified by the latest contract extension.

“This business certainty is beneficial to Wallis, but it also gives us the capacity to plan for the long-term on site at Murrin Murrin and deliver the best operational outcomes.”

Grant Wallis said: “Our work at Murrin Murrin has helped us grow from a small family business to one of Australia’s largest privately-owned minerals drilling companies, while still remaining true to our local WA roots.”

Nic Fenner, Head of Mining Technical Services at Murrin Murrin, said: “We are very proud to help grow local Western Australia businesses, like Wallis Drilling, and help be a part in their success stories.

“The strong relationship between Murrin Murrin Operations and Wallis has been underpinned by our shared values and culture. Murrin Murrin and Wallis both have many long serving employees with some even being the second generation in their family to work at Murrin Murrin.”

Base metals, Energy minerals, Mineral processing, Mining services, Sustainable mining, , , , , ,

Clariant Mining Solutions has opened a dedicated global Competence Center for Decarbonization Minerals (CCDM) at the Dubai Science Park in Dubai, United Arab Emirates (UAE).

This laboratory is designed to meet the increasing global demand for solutions to process decarbonisation minerals more efficiently, it said.

The decarbonisation of the production and transportation of goods and services is a growing megatrend. Mining is one of the key foundational industries enabling decarbonisation by delivering the minerals required for these technologies, such as nickel, cobalt and lithium for batteries for electric vehicles, rare earths for magnets in wind turbines and alumina for lighter-weight vehicles and solar panels.

Research activities will include improving metallurgical performance by maximising recovery and grade, optimising cost performance, and creating more sustainable solutions for the processing of decarbonisation minerals, it said.

“Our new Competence Center is another important milestone in our purpose-led strategy to become a sustainability leader in mining chemicals,” George Nunes, Global Head of Clariant Mining Solutions, said.

Horizonte Minerals Plc has awarded Wood Plc the principal engineering contract to undertake the feasibility study for its 100%-owned Vermelho nickel-cobalt project, in Brazil.

Vermelho is a large high-grade, long mine life, scalable resource, designed to be a low-cost producer of nickel and cobalt for the battery industry, Horizonte says. The Vermelho FS contract award is another key milestone for Horizonte as it advances towards its long-term objective of becoming a 60,000 t/y nickel producer, following the start of construction at Araguaia, its ferronickel project, early this year, which is on schedule to produce first nickel in the March quarter of 2024.

Vermelho is designed to produce 25,000 t/y of nickel and 1,250 t/y of cobalt over a 38-year mine life. The prefeasibility study (dated October 2019) estimated a post-tax internal rate of return of 38.6% using a nickel price of $23,000/t.

Wood, Horizonte says, is a global leader in project delivery, engineering and technical services with experience across a number of the major high pressure leach nickel operations globally.

Jeremy Martin, CEO of Horizonte Minerals, said: “The commencement of the feasibility study is an important step forward in unlocking Vermelho’s significant value. There are very few nickel resources of this scale and quality at an advanced stage of development, leaving Vermelho well positioned to capitalise on the growing demand for sustainable critical metals.

“Vermelho is located in the Carajás mining district, an area that features well-developed infrastructure and hydroelectric power. The project is designed to produce nickel in intermediate or refined form and will be a globally significant, non-conflict, ethical source of cobalt.

“Araguaia and Vermelho have a combined inventory of over 4 Mt of nickel. By leveraging the synergies of these two world-class projects, located within trucking distance of each other in a stable and pro mining jurisdiction, Horizonte is well positioned to deliver its growth target of producing 60,000 t of nickel per year, placing the company amongst the global leaders in primary nickel production outside Indonesia.”

Wood (formerly GRD Minproc) undertook a successful Vermelho feasibility study for Vale between 2003 and 2006. In this regard, it already has a detailed understanding of the project, enabling it to leverage this existing knowledge during the process of producing this updated study for Horizonte, the company said.

Shell Consortium previews Charge On haul truck electrification solution

Environmental, Mining equipment, Mining services, Power supply for mines, Sustainable mining, , , , , , , , , , , , , , , , , , , , ,

Shell has become the latest Charge On Innovation Challenge winner to unveil details about its electric haul truck charging solution, outlining how its consortium of partners intend to combine an end-to-end and interoperable electrification system that reduces emissions without compromising on efficiency or safety, while aiming to be cost competitive versus diesel-powered operation.

The Charge On Innovation Challenge was launched in 2021 and invited vendors and technology innovators from around the world and across industries to collaborate with the mining industry to present novel electric truck charging solutions. The challenge received interest from over 350 companies across 19 industries, with more than 80 companies submitting expressions of interest. Twenty-one companies were then invited to present a detailed pitch of their solution, with the final eight – which included the Shell Consortium – chosen to progress from these 21.

The global challenge, launched by BHP, Rio Tinto and Vale, sought to accelerate commercialisation of effective solutions for charging large electric haul trucks while simultaneously demonstrating there is an emerging market for these solutions in mining.

The Charge On Innovation Challenge requested international solution providers to put forward charging concepts that are:

  • Designed with safety as the number one priority, using inherent defensive design and future-proof principles;
  • Able to supply a battery for 220-t payload electric haul trucks;
  • Capable of supplying 400 kW hours of electricity to a truck during each haul cycle;
  • Able to provide battery charging, or both propulsion and battery charging;
  • Cost effective, minimising complexity without reducing productivity; and
  • Interoperable, allowing different haul truck manufacturers to utilise the same charging infrastructure.

On a media call this week, Shell highlighted how its consortium of nine partners was working on a solution that could not only meet this brief, but also provide a commercial offering to electrify mining and other industries.

Skeleton, Microvast, Stäubli, Carnegie Robotics, Heliox, Spirae, Alliance Automation, Worley and Shell have come together to introduce Shell’s mining electrification solutions for off-road vehicles. This consists of:

  • Power provisioning and microgrids, with the aim to provide a consistent and reliable supply of renewable power in a safe and stable manner;
  • Ultra-fast charging whereby an approximate 90-second charge via flexible, hardwearing and resilient, on-site, ultrafast charge-points can provide assets with continuous operation of some 20-30 minutes depending on the haulage profile; and
  • In-vehicle energy storage: through a combination of advanced battery and capacitor technologies that aim to deliver long lifetimes, ultra-fast charging and high performance.

Some of the key components of the power provision and energy management solution come from Alliance Automation, a multi-disciplined industrial automation and electrical engineering company; Spirae, a technology company that develops solutions for integrating renewable and distributed energy resources within microgrids and power systems for economic optimisation, resiliency enhancement and decarbonisation; Worley, an engineering company that provides project delivery and consulting services to the resources and energy sectors, and complex process industries; and Shell Energy, which provides innovative, reliable and cleaner energy solutions through a portfolio of gas, power, environmental products and energy efficiency offers to businesses and residential customers.

The ultra-fast charging element involves solutions from Carnegie Robotics, a provider of rugged sensors, autonomy software and platforms for defence, agriculture, mining, marine, warehouse and energy applications; Heliox, a leader in fast charging systems within public transport, e-trucks, marine, mining and port equipment; and Stäubli, a global industrial and mechatronic solution provider with four dedicated divisions: electrical connectors, fluid connectors, robotics and textile.

Finally, Skeleton, a global technology leader in fast energy storage for automotive, transportation, grid and industrial applications, and Microvast, a leader in the design, development and manufacture of battery solutions for mobile and stationary applications, are in charge of the in-vehicle energy storage side of things.

As a result of this collaboration, mining operators, Shell says, are set to benefit from an integrated electrification solution that:

  • Is end-to-end, covering the full journey of the electron from generation to delivery in the drivetrain;
  • Is interoperable between different original equipment manufacturer make and models, giving mining operators greater flexibility;
  • Is modular in design to allow mining customers the opportunity to tailor solutions to their specific needs; and
  • Reduces emissions without compromising on operational efficiency or safety.

Sebastian Pohlmann, Skeleton Technologies’ Vice President Automotive & Business Development, revealed more details about the plans for the in-vehicle energy storage part of the equation, confirming that the fast energy storage solution set to be fitted on these 220-t payload haul trucks would leverage its SuperBattery.

The SuperBattery, Pohlmann said, offers a 100 times faster charging option compared with standard lithium-ion batteries, while also being free of cobalt, nickel, graphite and copper materials. He also mentioned that a SuperBattery-equipped haul truck could, in the right situation, offer higher utilisation than its diesel-powered equivalent.

The SuperBattery is due to start production in 2024, with Pohlmann saying the battery lined up for a prototype system as part of the Shell Consortium would weigh in at just over 12 tonnes. He also highlighted the potential for other applications in mining outside of 220 t haul trucks with this platform.

The ultra-fast charging solution that the consortium partners were working on assumed a peak power delivery of 24 MW, Pohlmann said, explaining that the charge points would be positioned around areas where haul trucks normally come to a stop – during dumping or loading, for instance – meaning charging would not interrupt the haul cycle and ensure high utilisation of the truck at all times.

With such a high power draw envisaged by the partners, Grischa Sauerberg, Vice President, Sectoral Decarbonisation & Innovation at Shell, explained that a stationary power element – renewable energy and battery storage – may also be provided if the grid power available cannot support such a peak draw.

The commercial offering from the partners is expected in 2025, however Sauerberg confirmed a pilot solution was set to be tested at a Shell facility in Hamburg, Germany, next year, followed by final field trials at selected mine sites in 2024.

Gradiant concentrating its mining proposition

Automation, Base metals, Environmental, Mineral processing, Mining services, Mining software, Water management, , , , , , , , , , , ,

There are plenty of mining applications one can see Boston, Massachusetts-based Gradiant’s end-to-end water technology solutions serving.

A spinout of the Massachusetts Institute of Technology, the company calls itself the “experts” of industrial water, water reuse, minimum liquid discharge (MLD) and zero liquid discharge (ZLD), and resource recovery of metals and minerals.

That is a big remit, hence the reason why it caters to at least nine industries on a global basis in mission-critical water operations, with over 70% of its clients being Fortune 100 companies in the world’s essential industries.

Mining companies have historically been wary of suppliers that serve a variety of industries, believing their needs rarely cross over with the requirements of other industries. Gradiant believes it is different in that its solutions incorporate not only the hardware and software to fine-tune water technologies, but also the artificial intelligence (AI) to ensure the tools being used are effective regardless of the inputs.

This includes the RO Infinity™ (ROI™) platform of membrane-based solutions for complex water and wastewater challenges, which combine Gradiant’s patented counterflow reverse osmosis (CFRO) technology with reverse osmosis and low-pressure membrane processes. ROI solutions enable customers around the world to achieve sustainability goals to reduce their water and carbon footprint, the company says.

This platform is complemented with AI-backed SmartOps™, an integrated digital platform for asset performance management to optimise and predict plant operations using historical and real-time process data, resulting in performance and cost efficiencies.

Prakash Govindan, Co-Founder and COO of the company, says most water solutions on the market are built for consistent liquid/solid feeds and work effectively when the input is in accordance with these specifications. When the feed changes, they often become ineffective, needing to be updated or changed out, which costs money and impacts the various processes on either side of the water treatment section.

“The machine-learning algorithms we use – neural networks and time-series algorithms – ensure we consistently optimise the operation of our solutions,” Govindan told IM. “These tools make sure we always use the right performance metrics and don’t lose efficiency in the face of variability.”

The algorithms cannot change the hardware built into the water treatment plant, but it can, for instance, change the speed of the pumps or blowers. “We call it balancing, which is all part of our IP portfolio,” Govindan said.

SmartOps is an integrated digital platform for asset performance management to optimise and predict plant operations using historical and real-time process data

For mining companies looking to employ water treatment tools at their operations, this results in Gradiant’s technology being able to concentrate metals to a higher degree than any other solution on the market, according to Govindan.

“We can concentrate an aqueous solution to the point where you can produce a solid material that miners can then process,” he said.

Considering desalination applications represent a significant portion of the company’s work to this point – through its CFRO process – the mining sector has already provided some wins.

The CFRO process enables remote inland desalination and water reuse that was not previously possible due to a lack of viable brine management solutions, according to Gradiant, concentrating brines to saturation for disposal or crystallisation while producing a purified product water stream for beneficial reuse.

One significant nickel miner in Australia with a brine stream is using this solution to recover large amounts of concentrate it can feed through to its captive processing plant to produce an end-use product.

“Gradiant’s technologies enable clients to recover more than 50% of the nickel and cobalt from leached brine – this stream would have otherwise been wasted without our solutions,” Gradiant said. “Overall, this was a client benefit of about 20% increase in nickel and cobalt production across the entire operation.”

When considered together with the energy savings (75%), freshwater savings (25%) and environmental benefits, Gradiant continues to see high interest from miners around the world to adopt its solutions, it says.

That is before even factoring in the other complementary benefits that come with using SmartOps.

“All our products benefit from in-built sensors that not only allow us to update the operating parameters based on the detected materials, but also carry out scheduled maintenance on the hardware using these algorithms,” Govindan said. “This allows us to carry out 30-40% less service intervals than many conventional suppliers as we only take the solution out of operation based on what the data is telling us.

“Not only this, but we also have complete oversight of these parameters from remote locations, meaning you can monitor the systems from remote operating centres and not remain on site after installation.”

With mines getting more remote and hiring local employees getting even harder with the well-documented skills shortages, Gradiant feels its solutions will continue to win miners over.
