XCMG 72-t battery-electric trucks start up at Vale operations

Vale says it has become the first major mining company to test 100% electric 72-tonne trucks, with the trial of the XCMG Mining Machinery Co. Ltd vehicles at its Brazil and Indonesia operations.

The trial of the vehicles represent another step in the electrification of the company’s assets, it said, which is part of its wider plans to operate with net zero carbon emissions by 2050.

The first electric trucks to be used by a global mining company, tested at Água Limpa, in Minas Gerais, and Sorowako, in Indonesia, emit no CO2, replacing diesel with electricity from renewable sources. They also reduce noise, which minimises the impacts on the communities that live near the operations.

The equipment was produced by XCMG Mining Machinery Co. Ltd., a subsidiary of Xuzhou Construction Machinery Group Co. Ltd, the largest machine manufacturer in China.

Last year, Vale signed an MoU with XCMG Construction Machinery Limited, a subsidiary of XCMG, for the potential supply of mining and infrastructure equipment, including zero-emission and autonomous equipment.

The 72-t electric off-highway trucks, model XDR80TE, are part of the Vale PowerShift program. Their batteries are able to store 525 kWh, allowing them to operate for up to 36 cycles along the established route, just over a day of operations, without the need to stop and recharge, and with the possibility of regenerating energy during descents, reducing the use of mechanical brakes, maintenance work and vibration, in addition to providing more operational comfort to drivers. The machine has temperature control technology, which allows it to adapt to high temperature, humidity and rainy working conditions, and to perform even in extremely cold, high altitude and harsh weather conditions.

Alexandre Pereira, Executive Vice President of Global Business Solutions at Vale, said: “To us, this partnership with XCMG is another important step in our long-term relationship with China and towards more sustainable mining. Our goal is to expand, together with global partners, the development and co-creation of technologies that respect the environment and zero out emissions.”

Dr. Hanson Liu, the Vice President of XCMG Machinery and General Manager of XCMG Import & Export Co., said: “XCMG and Vale have reached a consensus on the green development concept of dedicating to low-carbon mining and realising net zero emissions. The delivery of XCMG’s latest pure electric mining truck, XDR80TE, at this time is a manifestation of the joint efforts of both parties on promoting global environmental protection as well as green and sustainable economic development.”

Currently, emissions from off-highway trucks running on diesel represent bout 9% of Vale’s total scope 1 and 2 emissions.

The Powershift program was created by Vale with the aim of replacing fossil fuels with clean sources in its operations. The program is promoting innovative solutions to electrify the company’s mines and railroads. In addition to the 100% electric truck, Vale’s strategy for the electrification of assets also includes the operation of battery-powered locomotives in the yards of the ports of Tubarão, in Vitória, and Ponta da Madeira, in São Luís. In Canada, the Powershift program has also led to tests with electrical equipment in underground mines – there are currently about 40 that are currently operational.

Vale’s operational equipment electrification strategy also includes a partnership with its peers BHP and Rio Tinto. Last year, the three companies, along with 17 other mining companies, launched the Charge On Innovation Challenge, a global open innovation challenge with the goal of finding innovative solutions to accelerate the safe charging of batteries for future electric off-highway trucks.

PT. Putra Perkasa Abadi starts training operators with Immersive PRO5 simulator

PT. Putra Perkasa Abadi (PT. PPA) has became the first company in Indonesia to incorporate Immersive Technologies’ PRO5 Advanced Equipment Simulator technology, with the first two of four units commissioned in the PPA office at the PT Multi Harapan Utama mine site.

Launched at MINExpo 2021, the PRO5 Advanced Equipment Simulator set a new benchmark in realism, reliability and training value for operator training technology, according to Immersive.

A commissioning celebration and handover was carried out by Edwin Trisnohadi, Regional Vice President Immersive Technologies Asia & Indonesia region, and Director of PT. PPA, R. Teguh Sapto Subroto. Also present at the event were Sunaryo, Head of PPA Academy, and Teddy Ramdani, Customer Support Manager of PT. United Tractors, Tbk.

Equipped with a professional-grade visual system, the PRO5 is the first mining simulator to combine stereoscopic 3D, a one-piece curved display, photo-realistic graphics and RealView™ head tracking technology, according to Immersive. It delivers realism at a level not previously seen by the mining industry, according to the company, with these advancements helping new and experienced mining equipment operators develop competencies at a rapid pace, while maintaining high levels of learning retention.

Previously, in order to improve the competence of newly graduated workers, PPA’s only option was on-iron training. This takes extra time and also has safety risks. Now, these novice “green” workers can develop psychomotor skills and learn critical behaviors in a safe, simulated environment, while also reducing fuel consumption, according to the company.

PPA is a mining contractor, which, in recent years, has recorded significant growth to become the third largest contractor in the Indonesian mining industry.

The speed of growth requires an investment in the workforce and training tools to become more effective and efficient and to prepare personnel to become mine-ready. This year, PPA is targeting an additional 100 million bank cubic metres (BCM) above last year’s 267 million BCM. In order to achieve this target, an additional 3,200-3,500 operators are needed. The company also needs an additional 1,500-2,000 mechanics. PPA targets an addition of 150 million BCM next year, with another circa-6,000 mechanics and operators needed to support this.

To onboard 6,000 workers, PPA can no longer rely on outdated training techniques.

R. Teguh Sapto Subroto said: “Simulators will help us to develop personnel at a safe and steady pace, independently of disruptions such as weather conditions. We need this technology.”

Before arriving at the decision to buy four PRO5 platforms, PPA had made an in-depth study of simulation vendors and related solutions, according to Subroto. This involved proof of concept product testing from Immersive Technologies.

“The biggest challenge in workforce development is to rapidly develop quality talent with the skills to be safe and productive,” Subroto said. “If you recruit well, you will compete with others, but skill levels may remain 30% below ideal. To produce a quality workforce, you need the right tool that make humans more efficient and effective.”

The simulators will later be managed by the PPA Academy.

Ramdani said that this latest PRO5 simulator has only been available to the market for a short period of time and PPA incorporated it rapidly because of the value it could bring. “Hopefully it can help PT. PPA in building worker competencies, especially for operators,” he said. “PPA recorded the highest growth in the industry which must be balanced with the quality of qualified workforce.”

Trisnohadi explained: “This level of realism and reliability will help companies produce quality workforces and significant return on investment. Our goal is to help PPA in obtaining a world-class workforce, which ultimately would result in greater operational efficiency.

“This PRO5 simulator is the cutting-edge product from Immersive Technologies with the latest evolution of display systems. It is a combination of seamless curve screen with stereoscopic 3D technology which provides unmatched training value and highest levels of learning.”

“This new contract is an opportunity to continue our record of delivering excellence for our clients in Indonesia, with a clear focus on safe, responsible production and industry leading rehabilitation.”

Thiess Executive General Manager Asia, Cluny Randell, added: “This contract is recognition of our team’s ability to deliver long-term performance and productivity gains for clients.

“We look forward to working together with our client and the local communities to deliver long-term social, environmental and economic value.”

A day earlier, Thiess confirmed that its mining services contract at Peak Downs Mine in Queensland, Australia, had been extended for another five years by BHP Mitsubishi Alliance (BMA).

Located southeast of Moranbah, Peak Downs is an open-pit mine producing high-quality steelmaking coal and is one of Australia’s largest mines by recoverable coal reserves.

Under the contract, Thiess will continue to operate and maintain mining equipment to move additional overburden at the mine and support BMA’s production requirements over the next five years. Starting from July 2022, revenue to Thiess is worth over A$700 million.

Metso Outotec to deliver 100th Anode Casting Shop to Indonesian copper smelter

Metso Outotec says it will deliver its 100th Anode Casting Shop to PT Smelting’s (PTS) copper smelter in Gresik, East Java, Indonesia.

The OEM, which says it has been a frontrunner in the development of anode casting technology for several decades, says the Gresik project is a true milestone for the company.

Today, most of the world’s copper anodes are produced with Metso Outotec’s proprietary anode casting technology, it stated.

Sami Maaniittu, Director, Anode Casting, Metso Outotec, said the system to be delivered to PTS is one of the world’s largest Twin Wheel Anode Casting Shops with a guaranteed capacity of 120 t/h.

Metso Outotec’s predecessor companies started the development and testing of automatic anode casting already in 1969 in Harjavalta, Finland.

“Before that, castings were made manually with controlled ladle tilting,” Maaniittu said. “The first anode weighing and casting machine was delivered to the USA in 1972, and a year later, the first complete anode casting shop was installed at the Harjavalta Smelter in Finland.”

Metso Outotec’s Twin Wheel Casting concept, paving the way for today’s standard, was developed in the 1990s. The equipment design significantly improves casting capacity and provides more efficient use of floor space, according to the company. The wheels are supported on large centre bearings and driven by double drive systems developed to eliminate the backlash effect in the wheel movement and to ensure even quality.

The first Twin Wheel Anode Casting Shop systems were delivered in 1997. Since then, the Twin Wheel has become the first choice of high-capacity anode casting shops, according to Metso Outotec.

Today, most of the anode casting shops supplied by Metso Outotec are fully electric without any hydraulic systems. Their high level of automation ensures premium anode quality with excellent weight accuracy and low reject rate combined with high capacity and availability, the company said. Metso Outotec Anode Casting Shops are safe and easy to operate and feature low energy consumption.

In addition to full anode casting systems, Metso Outotec offers a variety of modular updates for the existing installations, including automation and services.

Metso Outotec has been awarded what it says is a major contract for the delivery of sustainable tailings filtration technology to PT Huafei Nickel Cobalt’s greenfield laterite nickel ore project in Indonesia.

Metso Outotec’s scope of delivery consists of the engineering, manufacturing and supply of the Planet Positive Larox® FFP3512 filters, as well as installation and commissioning advisory services and spare parts.

The fully automatic fast-opening filter press (FFP) combines the benefits of membrane technology and sidebar design with high mechanical and process performance, providing safe and sustainable high-volume dewatering of tailings with low operating and life cycle costs, Metso Outotec said.

The hydrometallurgical plant has a targeted annual output of 120,000 t of nickel metal and is expected to be in operation during the June quarter of 2023.

Metso Outotec’s Planet Positive portfolio, which the Larox FFP3512 filters are a part of, focuses on the most environmentally efficient technologies – of which there are more than 100 – in the company’s current portfolio, responding to the sustainability requirements of its customers. The customer requirements relate to energy or water efficiency, reduction of emissions, circularity and safety, Metso Outotec says.

Jussi Venäläinen, Vice President, Filtration business line at Metso Outotec, said: “For our customer, the key criterion for selecting Metso Outotec’s filtration technology was safe and sustainable tailings processing with proven service capability. In addition, we were able to meet the customer’s wish for a quick delivery time.

“We are very pleased to have been chosen as the solution supplier, and we look forward to working together with our customer on this important project.”

Metso Outotec’s filtration product portfolio is the largest in the field and the energy, emission and water efficiency is in a league of its own, the company said. It has carried out over 14,000 filtration tests and delivered more than 5,000 filters for various applications worldwide. Most of the filters are sold under the Larox product name along with Metso Outotec corporate branding. Metso Outotec also accommodates all filtration-related service and spare parts needs through its global service network.

The value of the order is over €30 million ($33 million), and it has been booked in Minerals’ Q1 (March quarter) 2022 orders received.

Widespread demand for truck trays and buckets boost Austin’s order book

Austin Engineering Limited says it has received A$82 million ($61 million) of new orders across its business in the three months until end-February 2022, as orders for its specialist truck trays and buckets continue to come in.

This boost represents a 100% increase in its order book level compared with the same period of its last financial year.

Austin says it is now confident it has received sufficient orders to cover its 2022 financial year revenue guidance. In addition, Austin has also received a very encouraging level of orders for its 2023 financial year pipeline. Overall, enquiry levels and contract win rates remain strong in all home markets, it noted.

The new contract wins have resulted in a significant order book lift from December 2021, when Austin reported an increase in orders of 35% year-on-year.

The order book improvement is across all of Austin’s home markets but dominated by the US, Chile and Indonesia.

Austin explained: “The truck tray business has remained strong but is now widespread across more jurisdictions and has been supported by a much stronger level sales of buckets and other equipment. Austin’s new JEC High performance bucket range has attracted considerable attention and, with four months to go in the current financial year, the company has already achieved a record level of sales of mine buckets compared to recent years.”

Austin has previously announced a series of measures aimed at improving its competitiveness by sharpening its focus on the needs of its customers, both in Australia and overseas. As an example, this approach has led to an update to its core Ultima truck trays to meet increased demands around safety and weight carrying capacity.

The design updates have been coupled with cost efficiencies from the advanced manufacturing approach and the hub-and-spoke build strategy, increasing Austin’s product quality and cost competitiveness in the market, it said. This action has already delivered a material level of new order wins, strengthening the current financial year order book, and driving momentum into the next financial year.

Austin is now rolling out the initial phase of its advanced manufacturing plan, following an intensive design phase, which aims to increase production efficiency, safety and quality, thereby reducing costs and increasing productivity. The company is now initially rolling out the new production system in Batam, Indonesia, because that facility is running at an elevated level of throughput in a trend that is expected to continue.

The company flagged in its first half 2022 financial year results that it was entering a challenging period in Western Australia, which is currently under Level 2 Government restrictions due to rising COVID-19 cases in the state. Potential risks, which to a limited extent are now being experienced, include loss of productivity due to staff shortages and shipping delays, which could impact scheduling and deliveries for Austin and its suppliers. The current level of restrictions is not anticipated to remain in place for long, with Western Australia’s COVID-19 caseload peak expected in the next few weeks. Contingency planning continues to reduce risks where possible.

RCT continues to support PT Freeport Indonesia on technology journey

PT Freeport Indonesia has successfully operated one of the largest mining operations in Indonesia for decades thanks to its ability to embrace technology solutions to enhance its mining operations, smart technology specialist and Freeport supplier RCT says.

Freeport runs copper, gold and silver mines across five separate underground and surface operations in the highlands area of West Papua in Indonesia.

For over 30 years Freeport has enlisted the services of RCT to achieve its goals of making mining operations safer for workers and to optimise operations.

In the early 1990s, Freeport implemented RCT’s ControlMaster® remote control solutions across its mixed Sandvik and Wagner production mining fleet operating in the DOZ underground mine and the Grasberg open pit.

ControlMaster was the ideal solution for Freeport’s mixed mining fleet due to its ability to integrate with any machine type and grant the user effective control of the machine from a safe vantage point, according to RCT.

This has seen RCT go from supplying ControlMaster remote solutions, to performing full machine rewiring projects on-site across the underground LHD fleet. It also included deploying the ControlMaster remote control technology across the surface mining fleet, including Cat D11 and D10R dozers, and installing teleremote technology onto a Cat 994 wheel loader within the open-pit mine.

RCT has also previously commissioned ControlMaster Line-of-Sight remotes onto a variety of surface drills, including a Commando drill and Cubex drill rigs as well as a fixed position rockbreaker.

Over the years Freeport’s technology requirements have evolved and every time RCT has supplied technology in-line with changing expectations, from providing analogue communications equipment through to more current digital networks, RCT said.

At present, RCT is providing bespoke technology solutions to Freeport’s entire fleet of specialised equipment.

RCT Account Manager, Shane Smith, said the local environment presents many unique challenges and Freeport is determined to address these issues with technology, and mine in a safe way.

“Due to hazardous conditions in the underground mines, such as wet muck rushes, Freeport sought to automate water cannon trucks, mobile rockbreakers and other highly specialised equipment,” he said. “Global OEMs were not able to deliver technology to meet Freeport’s standards and so we customised our own technology to create a solution that suits their specific applications. This has been so successful that Freeport now instructs global OEMs that their machines must have an RCT solution fitted at a factory level.”

He added: “The current working relationship between Freeport and RCT is built on the foundations of many years of hard work in delivering effective automation solutions and supporting that technology.”

In 2015, Freeport asked for a RCT specialist to be deployed permanently on-site to provide a high level of support for the extensive range of automation solutions implemented across the mines.

These solutions include deploying the ControlMaster semi-autonomous technology on Cat R1700 and R2900 loaders, which can be managed by operators in Freeport’s central Remote Operation Room (ROR) on the mine’s surface.

Other projects include automating 24 chute systems spread across the Big Gossan, DOZ and DMLZ mines and relocating the chute operator from the gantry to the ROR.

Freeport has also implemented RCT’s Haul Truck Operator Assist technology to optimise underground truck loading operations.

Most recently, RCT commissioned a secondary breakage fleet at Big Gossan, including Getman and Elphinstone water cannon trucks, mobile rockbreakers and Cat skid steers. The mobile rockbreakers have been commissioned with RCT’s autonomous ControlMaster technology and enables personnel to manage machine operations from the safety of the ROR.

Smith said going forward the team will enhance the Multi Fleet Select capability, which will enable site personnel to operate multiple machine types from one Automation Centre on the mine’s surface.

“We will soon have nine new Automation Centres located in Freeport’s ROR and we will fully support local personnel in the ramping up of their autonomous fleet operations,” he said. “Freeport is at the forefront of embracing technology to enhance their mining operations and we are very pleased to support them in this journey.”

Nickel Mines targets further CO2 cut with SESNA solar power MoU

Nickel Mines Ltd has signed a memorandum of understanding (MoU) with PT Sumber Energi Surya Nusantara (SESNA) to implement, if certain economic parameters are met, 200 MWp of solar capacity within the Indonesia Morowali Industrial Park (IMIP).

The MoU provides for SESNA to undertake the role of “Project Initiator” for developing, financing, constructing, commissioning, owning and operating a 200 MWp solar farm project to significantly scale up the supply of renewable energy to the company’s Hengjaya Nickel (HNI) and Ranger Nickel (RNI) nickel processing operations within the IMIP.

Under the proposed agreement, Nickel Mines will be the long-term offtake partner for SESNA and will not be required to contribute any capital funding. The indicative tariff for electricity is considered competitive with other similar scale solar projects, the company said.

SESNA is, Nickel Mines says, an established and leading solar development company in Indonesia, owning and operating a portfolio of solar feed-in-tariff (FIT) and microgrid projects as well as providing services and solutions such as engineering, procurement and construction (EPC) capabilities, solar financing and other technical development support to commercialise solar projects.

The potential 200 MWp solar project supplements the existing 396 kWp plus 250 kWh battery storage project which the company has entered into with SESNA for integration into the facilities at the Hengjaya mine (pictured), which is scheduled to commission this quarter. The Hengjaya mine, which hosts a JORC compliant resource of 185 Mt at 1.3% Ni and 0.08% Co, currently sources its power from diesel-powered generators. It is anticipated that the Hengjaya mine solar project will reduce diesel consumption by approximately 31 million litres over the 25-year projected project life.

Nickel Mines Managing Director, Justin Werner, said: “It is estimated this solar project could supply up to 20% of HNI and RNI’s current electricity requirements and, in doing so, account for a material reduction in annual CO2 emissions. This solar project marks an important first step in our ’Future Energy’ collaboration with our partner Shanghai Decent and our joint commitment to a more sustainable future for Indonesia’s nickel industry.”

The solar project may be implemented in stages with SESNA committing to finalise and deliver a project proposal within three months of signing the MoU, at which point the company may elect to proceed or terminate the MoU at its discretion.

Eramet re-energises Argentina lithium development with help of Tsingshan

Eramet plans to restart construction of its lithium production plant in Argentina after signing an agreement with Tsingshan that will see the China-based steel group finance the build in exchange for a 49.9% interest in the project.

The construction of the 24,000 t/y lithium carbonate equivalent plant will start during the March quarter of 2022, with commissioning scheduled for early 2024.

Eramet and Tsingshan have an existing relationship with the two companies jointly owning the Weda Bay nickel operations in Indonesia.

“With this project, Eramet will become the first European company to develop sustainable and large-scale lithium production, supported by a performing process developed in-house by its R&D centre,” Eramet said.

This is a two-step process that, firstly, uses an active solid to extract and concentrate the lithium. Developed by Eramet in liaison with IFPEN (the French Institute of Petroleum and New Energies) and Seprosys, this works like a sponge, capturing the lithium contained in the brine. Fresh water is then used to release the stored lithium. To further concentrate the extracted metal, two successive processes are then conducted: nanofiltration and reverse osmosis.

The lithium is then purified, after which a reaction occurs with sodium carbonate to convert it to lithium carbonate. Once filtered again and washed, it achieves the chemical quality of the finished product, Eramet said.

The lithium project was mothballed in April 2020 during COVID-19, as the conditions were not met to launch construction.

“Based on the partnership signed with Tsingshan and factoring in solid fundamentals as well as excellent outlook for the lithium market, the group’s Board of Directors has considered that the conditions are now met to launch the plant construction,” Eramet said.

Eramet will control the project, with a 50.1% interest. For its part, Tsingshan will contribute up to $375 million to the project through the financing of the plant’s construction, leading to it earning a 49.9% stake in the project.

Eramet owns perpetual mining rights over a major lithium concession, in the form of brine, located on the Andean highlands in Salta Province. The project plans to extract brine from the salar and process it into lithium carbonate. The 24,000 t/y LCE project is expected to have cash costs of around $3,500/t LCE ex-works, with large-scale drainable resources.

A pilot plant installed on the site since 2020 has demonstrated, in real conditions, the lithium carbonate production, which brought very high direct extraction yields of around 90%, according to the company.

“The project has strong ESG performance, notably as demonstrated by the quality of the relationships tied with local communities during the preparatory phase of the project,” the company said. “Eramet’s process also presents an advantage in terms of hydric resources use compared with projects supported by a conventional extraction process. All Eramet’s CSR standards will be applied on the activity.”

Christel Bories, Eramet Group Chair and CEO, said: “Our decision to carry out our lithium project in Argentina is in line with the dynamic of strong market growth. It is a key milestone in the deployment of our strategic roadmap, which aims at positioning Eramet as a reference player in metals for the energy transition.”

Thiess to continue mining at PT Wahana Baratama Mining coal mine in Indonesia

Thiess says it has secured a three-year A$220 million ($164 million) contract renewal to continue providing mining services at PT Wahana Baratama Mining’s coal mine in South Kalimantan, Indonesia.

Having operated at the project since 2007, Thiess will provide full mining services for Wahana, which is owned by Bayan Resources, including mine planning, environmental and water management, drill and blast, and mining and pit hauling services, it said. The contract renewal commences from November 2021.

Thiess CEO and Executive Chairman, Michael Wright, said: “This extension builds on our long-term partnership with Wahana and recognises Thiess’ ability to deliver sustainable and competitive mining solutions tailored to their operational needs.”

Thiess Executive General Manager Asia, Cluny Randell, said: “We’re proud to continue delivering value at Wahana, a unique operation where Thiess has mined two adjoining mines for two different clients. Our team is focused on continuing to optimise resource recovery and extending the mine’s reserves to deliver long-term value for Wahana.

“Alongside this, we’re looking forward to building on our COVID-19 vaccination efforts, extending our employee and family vaccination program into the community next month.”

Bayan Resources says the Wahana Baratama mine currently produces around 1-2 Mt/y of high calorific value bituminous quality coal.
