ERM on executing the mining sector’s sustainability strategies

With sustainability close to the number one topic shaping the business landscape, the mining industry faces perhaps more scrutiny today than ever before. From stakeholder engagement to employee welfare and the emissions generated from using mined commodities, there is a spectrum of issues on which mining companies are judged. Not just by traditional critics such as NGOs, but increasingly by policymakers, investors and consumers themselves.

As a result, mining companies are seeking the advice of consultants that live and breathe environmental, social and governance (ESG) issues to adapt to this evolving backdrop (see the mining consultants focus in IM October 2021 for more on this).

In this regard, they don’t come much bigger than ERM, which calls itself the largest global pure play sustainability consultancy. With a remit that goes into strategic, operational and tactical challenges, the company’s services have been in serious demand of late.

Louise Pearce, ERM Global Mining Lead; Jonathan Molyneux, ERM Mining ESG Strategy Lead; Peter Rawlings, Low Carbon Economy Transition Lead; and Geraint Bowden, Regional Client Director – Mining, were happy to go into some detail about how the company is serving the industry across multiple disciplines.

In demand

According to the four, there is increasing demand for services from miners interested in energy/battery minerals (lithium, cobalt, nickel, copper, platinum, palladium and rhodium (PGMs)) on the back of rising numbers of new mines coming onto the scene, “shorter supply chains to customers”, the perceived need to secure domestic supply of these minerals, and requirements of “evidence of responsibly-produced certifications from industry organisations such as the Initiative for Responsible Mining Assurance (IRMA)”.

Such trends have been underwritten by a shift in both the requirements and considerations around the extraction of these minerals, according to Molyneux.

“In the last five to seven years, the main ESG incentives for change have come from access to capital (ie investor ESG preferences, especially in relation to catastrophic incidents),” he said.

“Over the last three years, we have seen a strong rise in expectations from downstream customers, particularly leading brands.”

Jonathan Molyneux, ERM Mining ESG Strategy Lead

Automotive original equipment manufacturers like BMW and Daimler are placing sustainability at the centre of their brands, according to ERM. Their initial focus has been on ‘net-zero’ driving/electrification – and they have made progress on this with several major electric car launches. They then shifted to examining the carbon emissions and ESG, or responsible practices, of tier-one and tier-two component manufacturers. The last step has been a full analysis of the ESG credentials of input materials right back to source, ie the mine.

“We see a shift from the historic lens of customers managing supply risk by sourcing from organisations which ‘do little/no harm’ (eg human rights compliance, catastrophic incident avoidance) to supply partners that can contribute to the ‘do net good’ or ‘create value for all stakeholders’ (ie communities, workforce, nature positive),” Pearce said.

Such a shift has resulted in more clients considering “circular thinking” in their operational strategy, as well as carrying out risk reviews and transformation projects focused on a company’s social or cultural heritage. Tied to this, these same companies have been evaluating their water use, biodiversity requirements and, of course, decarbonisation efforts.

It is the latter on which the steel raw materials companies predominantly have been looking for advice, according to ERM.

The focus has been on ‘green’ iron ore, low-carbon steel and ‘circular’ steel, according to Molyneux and Bowden, with ERM providing input on how companies in this supply chain can integrate sustainability into their strategy and operations.

On the thermal coal side, meanwhile, it is a very different type of ERM service in demand: mine retirements, closure/local/regional regeneration transitions and responsible disposals.

Delivering on decarbonisation

The mining industry decarbonisation targets have come thick and fast in the last 18-24 months, with the latest announcement from the International Council on Mining and Metals (ICMM) seeing all 28 mining and metals members sign up to a goal of net zero Scope 1 and 2 greenhouse gas (GHG) emissions by 2050 or sooner, in line with the ambitions of the Paris Agreement.

Many have gone further than Scope 1 (direct emissions from owned or controlled sources) and Scope 2 (indirect emissions from the generation of purchased electricity, steam, heating and cooling consumed by the reporting company) emissions, looking at including Scope 3 (all other indirect emissions that occur in a company’s value chain) targets.

Fortescue Metals Group, this month, announced what it said is an industry-leading target to achieve net zero Scope 3 emissions by 2040, for example.

These are essential goals – and ones that all interested parties are calling for – in order to deliver on the Paris Agreement, yet many miners are not yet in the position to deliver on them, according to Pearce, Molyneux, Rawlings and Bowden.

“Miners need to look at decarbonisation at a holistic level across their operations and value chain, and cannot just delegate the net zero requirements to individual assets,” Rawlings said. “The solutions needed require investment and are often at a scale well beyond individual assets/sites.”

Much of this decarbonisation effort mirrors other industries, with the use of alternative fuels for plant and equipment, accessing renewable electricity supplies, etc, they said.

Process-specific activities can present challenges and is where innovation is required.

“These hard to abate areas are where a lot of efforts are currently focused,” Rawlings said.

Tied into this discussion is the allowance and estimates made for carbon.

There has been anecdotal evidence of miners taking account of carbon in annual and technical reports – a recent standout example being OZ Minerals inclusion of a carbon price in determining the valuation of its Prominent Hill shaft expansion project in South Australia – but there is no current legislation in place.

“We are seeing a broad spectrum of price and sophistication (targeted audience, knowledge level), but it is an active board level discussion for most clients,” Bowden said on this subject. “Most clients view this as market-driven requirements as opposed to a voluntary disclosure.”

This has been driven, in part, from the recommendations of the Task Force on Climate-Related Financial Disclosures, which many miners – including all the majors – are aligning their reporting with.

Some clients are also looking into scenarios to work around carbon regimes such as the Carbon Border Adjustment Mechanism, which proposes a carbon-based levy on imports of specific products.

Having acquired several companies in recent months focused on the low carbon economy transition – such as E4tech, Element Energy and RCG – ERM feels best placed to provide the technical expertise and experience to deliver the sustainable energy solutions miners require to decarbonise their operations.

“With these companies, combined with ERM’s expertise, it means we can support clients on the decarbonisation journeys from the initial strategy and ambition development through to implementation and delivery of their roadmaps,” Rawlings said. “We can support clients from boots to boardroom as they assess decarbonisation options and technologies; help them understand the financial, policy and practical aspects linked to deployment of solutions; and access the financing necessary to support deployment.”

ESG dilemmas

There is more to this evolving backdrop than setting and meeting ambitious environmental goals, yet, in ERM’s experience, the advice provided by consultants – and requested by miners – has historically been focused on individual ESG domains.

“This has often been driven by their realisation that their (miner’s) in-house policies and standards require updating,” Pearce said.

Louise Pearce, ERM Global Mining Lead

A siloed or disaggregated approach to ESG strategy development often reduces risk, but rarely generates value for the enterprise at hand, according to Pearce.

“What we have learned is that in order for organisations to create value, they need to focus on value drivers for the corporation,” she said. “These value levers are typically influenced by an integrated suite of ESG dimensions. For example, this could be looking at carbon emissions, connected with water use and nature, connected with local socio-economic development.”

“Sustainability and ESG are about understanding the inter-relationships between our social, natural and economic environments over the longer term. It cannot be about addressing one topic at a time or responding to the loudest voices.”

This is where ERM’s ‘second-generation’ ESG advice, which is driven by data and opportunities to create value as well as manage risk, is fit for the task.

“We are also finding that, at its heart, the central issue to second-generation ESG performance delivery/improvement for our clients is not just the strategy, but a willingness of organisations to reflect on their core values, how these have driven their traditional approaches and decisions and how they will need to evolve these if they want to achieve a genuine brand and reputation for ESG and achieve impact on the value drivers they have selected,” she added.

Such thinking is proving definitive in ERM’s mining sector mergers and acquisition due diligence.

“We have multiple experiences where clients have asked us to carry out an ESG review of a target portfolio, only to find that there is too great a gap between the target’s ESG asset footprint to align them with the client’s standard – or, that the carbon, water, closure or tailings profile of the target carries a too high-risk profile,” Molyneux said.

This is presenting clients with a dilemma as they want to increase their exposure to certain minerals, but are, in some instances, finding M&A is a too high-risk route. At the same time, the lead time to find and develop their own new assets is longer than they would wish for building market share.

Such a market dynamic opens the door for juniors looking for assets early in their lifecycles, yet it places a high load on the management teams of these companies to think strategically about the ESG profile of the asset they are setting the foundations for to eventually appeal to a potential acquirer.

“This is, in itself, a dilemma because, typically, the cash scarcity at the junior stage leads management teams to focus on the immediate technical challenges, sometimes at the cost of also addressing the priority non-technical challenges,” Bowden said.

Those companies who can take a strategic view on the ESG requirements of the future – rooted in a deep understanding of how to deliver change on the ground – will be best placed in such a market, and ERM says it is on hand to provide the tools to develop such an appropriate approach.

Speedcast makes new connections in the DRC with Mining Company Katanga contract

Speedcast, a communications and IT services provider, says it has been selected by Mining Company Katanga (MCK Sarl) for a three-year contract to deliver satellite connectivity services to its headquarters and a major mine complex in the Democratic Republic of the Congo.

As part of the agreement with the mining contractor, Speedcast will serve MCK’s Lubumbashi headquarters and the Ruashi open-pit copper and cobalt mine under contract with MCK, delivering “optimised wide-area networking over high-throughput, very small aperture terminal (VSAT), C-band satellite service and content filtering”, it said. The solution will enable internet access, cloud-based applications, IoT and crew welfare applications across their operations, according to Speedcast. All services will be fully supported by its global Customer Support Centers.

James Trevelyan, Senior Vice President of Enterprise and Emerging Markets at Speedcast, said: “We are thrilled that MCK has placed its trust in Speedcast to deliver critical, remote connectivity and network optimisation to its headquarters and contracted mining site. We have the highest-powered Cband network in Sub-Saharan Africa, which means we can enable the customer’s digitalisation agenda while delivering the highest performance primary or back-up communications solution.”

Hubert Nkonkosha, IT Manager at MCK, said: “Our Ruashi project is one of our largest refined copper and cobalt production sites with more than 2,000 people and suppliers employed. It’s vital to our headquarters and operations to have seamless communications and network management as we prioritise efficiency and digital transformation, now and in the future, while still operating cost-consciously. Speedcast was a clear choice for our needs, and we look forward to leaning on their team for support and expert guidance, building a strong working partnership for years to come.”

Speedcast recently augmented its Tier 1 satellite network across the Sub-Saharan African region with the addition of a new high-throughput satellite, offering ultra-high signal availability – even into 1.8 m terminals. The satellite’s look angle across Africa is around 60° elevation, making it ideal for steep-sided open-pit mines and resilient to equatorial weather patterns, according to Speedcast. It also incorporates the latest VSAT technology and a selection of bandwidth packages, from high-speed to gigabyte-only plans.

Perenti’s Barminco seals Savannah nickel project contract

Perenti Global’s hard-rock underground mining subsidiary, Barminco, has finalised a contract with Panoramic Resources for development and production works at the Savannah nickel project in the Kimberley region of Western Australia.

The finalised contract represents a value of around A$280 million ($208 million) over a four-year contract term, Perenti said.

Under the terms of the initial letter of intent, announced on the April 6, 2021, Barminco commenced mobilisation and early mining works ahead of the schedule. With finalisation of the contract, Barminco expects development and production works will ramp-up over the coming six months to achieve full run rate of revenue early in the March quarter of 2022.

The contract will be serviced by new underground mining equipment including the use of tele-remote mining equipment, expected to deliver both safety and productivity benefits, Panoramic said.

Ore processing at Savannah is scheduled to begin in November with first concentrate shipment from Savannah targeted for the following month, Panoramic said. The building of an ore stockpile on the surface has already commenced and the company plans for this to reach 100,000 t prior to turning on the processing plant.

Perenti’s Managing Director and CEO, Mark Norwell, said: “We look forward to working together with the team at Panoramic to develop what we all expect will be Australia’s next long-life nickel producing mine. Despite the challenging labour market conditions in Western Australia, we have been successful in mobilising a labour force of approximately 110 highly skilled underground employees. We expect this to increase to 170 as the project ramps up. Securing this labour force has enabled us to commence early works ahead of schedule.”

Savannah has outlined a 12-year mine life with an average annual production target of 9,072 t of nickel, 4,683 t of copper and 676 t cobalt in concentrate. The mine is set to operate at average site all-in costs of A$6.36/lb of payable nickel, net of copper and cobalt by-product credits and royalty payments. This equates to roughly $4.86/Ib or $10,714/t.

The operation, with more than A$100 million already invested, has been maintained since the suspension of operations in April 2020 with a view towards operational readiness and project optimisation. This includes the recent completion of the FAR#3 ventilation raise, underground capital development on four mining levels at Savannah North and ancillary capital works on surface and underground infrastructure, which are currently being completed, Panoramic says.

Cobalt Blue taps Honeywell for process control, automation, energy savings expertise

Honeywell and Cobalt Blue Holdings Limited have announced Honeywell will provide control, automation and energy optimisation solutions to help Cobalt Blue “streamline” its Broken Hill cobalt project (BHCP) and help to reduce the risk levels involved.

BHCP, which covers an area of 63 sq.km in New South Wales, Australia, intends to develop a new, reliable, global source of ethically-sourced cobalt.

Honeywell will deliver a wide range of solutions and services to enable Cobalt Blue to move BHCP seamlessly from pilot to production, including LEAP™ lean project execution; reusable engineering standards and templates; process control, enterprise performance management, energy optimisation solutions; and consulting and engineering services.

The collaboration also includes assistance in the development of a modular cobalt concentrator unit for BHCP, which can be applied for other mining and industrial waste streams project. This will improve cobalt recovery rates on running operations and reduce the environmental impact of old mine tailings, Honeywell said.

Joe Kaderavek, CEO of Cobalt Blue, said: “Our work with Honeywell will help us to de-risk and cost-optimise the process control, automation, and energy savings components of the BHCP project and reduce our time to market. Moreover, it will help us to meet our objective to produce 3,500 t of cobalt per year and meet rapidly increasing market demand.”

Andrew Hird, Director of APAC Growth and Sales Director, Pacific, Honeywell Process Solutions, said: “We’re committed to working with rare earth and green energy mineral partners such as Cobalt Blue to deliver sustainable products that help organisations around the globe achieve their carbon neutrality goals.

“Our technologies are ideally suited for this purpose, from automating operations to ensure a rapid response to evolving energy needs, to giving customers the capability to interpret data to make real-time decisions related to energy management and renewable energy systems.”

Honeywell recently committed to achieving carbon neutrality in its operations and facilities by 2035, building on the company’s record of reducing the greenhouse gas intensity of its operations and facilities, as well as its history of innovation to help its customers meet their environmental and social goals, the company said. About half of Honeywell’s new product introduction research and development investment is directed toward products that improve environmental and social outcomes for customers.

Sber and Eurasian Resources Group to cooperate on metals and mining ESG standards

Sber and Eurasian Resources Group (ERG) have signed a Memorandum of Intent to cooperate on developing environmental, social and governance (ESG) standards, including green financing instruments, for the metals and mining industry.

The document was signed by Andrey Shemetov, Senior Vice President and Head of SberCIB, and Benedikt Sobotka, Chief Executive Officer of Eurasian Resources Group.

The parties plan to develop ESG standards for the metals and mining industry, including relevant targets and metrics, and apply ESG-linked financial instruments to support mining and metals production. Sber and ERG will also collaborate on matters concerning investment and export opportunities, with ERG receiving advice and information support from Sber on ESG risk analysis.

Shemetov said: “We have been working with ERG, one of the world’s leading mineral mining and processing companies, for a long time, and this partnership has been fruitful. Mining and processing are vital to the economy, and we are aware they entail certain environmental risks. That is why it is most important that market players adhere to ESG principles.

“We welcome ERG’s willingness to evolve ESG-wise and, for our part, are ready to facilitate the development of the company’s sustainable practices while offering a variety of green products and joint projects. I am confident that this work will contribute heavily to the attainment of sustainable development goals by our companies.”

Sobotka added: “We are pleased to continue our partnership with Sber. ESG factors and sustainable development goals have been at the heart of the group’s activities for many years, while responsible ‘green’ investments for project financing are more relevant today than ever. The ethical production of the metals of the future, such as the cobalt needed to produce electric vehicles and gadgets, is essential for the transition to a green and lower-carbon economy. This is a major part of the group’s overarching mission.

“This agreement will facilitate the introduction of ESG principles into our decision-making processes as we implement innovative projects in our regions of presence. We are confident that the new collaboration with Sber will make a significant contribution to the group’s progress in this respect.”

Canada Nickel’s Crawford mine could be low carbon nickel leader, Skarn says

Canada Nickel Company, following an assessment from metals and mining ESG research company, Skarn Associates, claims its Crawford project in Ontario, Canada, could have an industry leading low carbon footprint, lower than 99.7% of existing global nickel production.

When in operation, Crawford is expected to produce 2.05 t of carbon dioxide (CO2) per tonne of nickel-equivalent production over the life of mine, which is 93% lower than the industry average of 29 tonnes of CO2, it said.

These results are based on a study by Skarn Associates, applying data from Canada Nickel’s preliminary economic assessment (PEA), the results of which were released on May 25, 2021. This study from Ausenco estimated annual average nickel production of 34,000 t over a 25-year life of mine, use of autonomous trolley trucks and electric shovels to reduce diesel use by 40%, and optimisation of the carbon sequestration potential of the tailings and waste rock. A feasibility study on the project is expected to be completed by mid-2022.

On the Skarn study, Canada Nickel said: “Importantly, this CO2 footprint estimate does not include the carbon offset expected to be provided from the process of spontaneous mineral carbonation from the tailings and waste rock comprised largely of serpentine rock which naturally absorbs CO2 when exposed to air.”

Mark Selby, Chair & CEO of the company, said: “This study demonstrates that Canada Nickel’s Crawford project can be a world-leading large scale, low cost nickel supplier while possessing an extremely low carbon footprint. I am particularly excited that we can achieve this result even before we include the carbon offset potential from our waste rock and tailings which we expect to allow us to produce NetZero NickelTM, NetZero CobaltTM, and NetZero IronTM.

“These results reflect the mine’s low strip ratio and our ability to utilise the low carbon hydroelectricity in the region and by using trolley trucks and electric shovels to reduce the consumption of diesel fuel.”

Skarn Associates’ proprietary E0 GHG intensity metric relates to Scope 1 and 2 mine site emissions from mining and processing of ore, plus fugitive emissions. It includes emissions from integrated smelting and refining facilities, but excludes emissions from third-party smelting and refining, Canada Nickel explained.

Emission intensities are stated on a recovered nickel-equivalent basis, calculated using average 2020 metal prices. Emissions are pro-rated across all commodities produced by the mine, based on contribution to gross revenue.

Panoramic, Primero and Barminco get to work on restarting Savannah nickel operation

Panoramic Resources Ltd, after a 12-month review process, has approved the restart of the Savannah Nickel Operation, in the Kimberley region of Western Australia.

The decision hinges on a 12-year mine life with an average annual production target of 9,072 t of nickel, 4,683 t of copper and 676 t cobalt in concentrate; as well as an offtake agreement with Trafigura that will also see the trading company provide a loan facility of up to A$45 million to cover the A$41 million of upfront capital cost required to restart the mine.

Savannah is set to operate at average site all-in costs of A$6.36/lb of payable nickel, net of copper and cobalt by-product credits and royalty payments. This equates to roughly $4.86/Ib or $10,714/t.

Savannah, with more than A$100 million already invested, has been maintained since the suspension of operations in April 2020 with a view towards operational readiness and project optimisation. This includes the recent completion of the FAR#3 ventilation raise, underground capital development on four mining levels at Savannah North and ancillary capital works on surface and underground infrastructure, which are currently being completed, Panoramic said.

The restart decision has led to divisions of Perenti and NRW Holdings being awarded significant contracts related to the resumption of mining activities.

Barminco, a subsidiary of the Perenti Group, has been awarded a four-year underground mining contract under a binding letter of intent and is scheduled to mobilise to site in July 2021. The contract will be serviced by new underground mining equipment including the use of tele-remote mining equipment, expected to deliver both safety and productivity benefits, Panoramic said.

The contractor was formally awarded the A$200 million contract back in February.

“Based on Barminco’s previous working knowledge at Savannah, opportunities to increase ore production and reduce dilution have also been identified,” the company added, explaining that underground mining is planned to commence in August, with ore to initially be sourced from both the Savannah and the Savannah North deposits.

Following an evaluation of an owner-operator model for the processing plant and a competitive contract tender process, Panoramic has also signed a non-binding letter of intent worth A$35 million with Primero (owned by NRW Holdings), which envisages a three-year agreement. The agreement relates to all processing and maintenance work at the Savannah processing plant, which has been maintained in “excellent condition” during the suspension, Panoramic said.

“A number of opportunities for improved recoveries through enhanced operating practices and minor capital projects have been identified,” the company added. As a result, the non-binding letter of intent with Primero has been structured to incentivise achieving higher than budget recoveries.

Panoramic is working with Primero to complete a binding contract in the coming months, but ore processing is set to restart in November 2021, allowing ore stockpiles to build for around three months (100,000 t) to de-risk ore supply issues.

The process plant at Savannah was commissioned in August 2004 and comprises a single stage crusher, SAG mill, flotation, thickening and filtering stages to produce a bulk nickel, copper, cobalt concentrate. Over the 2004 to 2016 initial operating period, metallurgical recoveries averaged 86-89% for nickel, 94-97% for copper and 89-92% for cobalt. The plant was originally designed for a throughput of 750,000 t/y, but consistently outperformed the design specifications with rates exceeding 1 Mt on an annualised basis, Panoramic said.

First concentrate shipment from the Wyndham Port is targeted for December 2021.

Vale sells New Caledonia nickel-cobalt operations to consortium

Vale confirms that its Vale Canada Limited subsidiary has concluded the sale of its ownership interest in Vale Nouvelle-Calédonie SAS (VNC) to the Prony Resources New Caledonia consortium.

The consortium of investors, including Trafigura, comprises a majority and non-dilutable shareholding for New Caledonian interests, Vale said.

Eduardo Bartolomeo, CEO of Vale, said: “After several months of negotiations, I am pleased that we concluded our divestment of VNC, benefitting employees, New Caledonia and all its stakeholders. Vale is fully committed to this transaction. It meets the guarantees required at the financial, social and environmental levels and offers a sustainable future for the operations.”

Vale’s intent from the beginning of the divestment process was to withdraw from New Caledonia in an orderly and responsible manner, with the company saying the deal accomplishes that.

Vale previously tried to sell the operations to Australia-based New Century Resources, but the two parties failed to reach an agreement.

The deal provides the former VNC operations with a financial package totaling $1.1 billion, of which Vale Canada Limited is contributing $555 million to support the continuity of the operations. The financing of the “Pact for the Sustainable Development of the Deep South” will also be secured by Vale, it said.

The Pact for Sustainable Development of the Deep South was signed on September 27, 2008, between Vale New Caledonia and communities south of the “Grand” for a period of 30 years. It urges the industry to create and implement specific measures to support the development of the Deep South in a sustainable manner.

In addition to its financial commitment to continue operations, Vale will continue to have the right to a long-term nickel supply agreement for a proportion of the operation’s production, allowing it to, the company says, continue addressing the growing demand for nickel by the electric vehicle industry.

Mark Travers, Executive Vice President for Base Metals with Vale, said: “Along with the continuation of the Pact, the deal also allows the Lucy Project for dry storage of tailings to proceed. We want to acknowledge the time and effort of all stakeholders to achieving this deal, including the French State, and especially the employees of VNC for their trust and support through a lengthy and uncertain process.”

VNC is a producer of nickel and cobalt from the Goro mine. It also has a processing plant and a port.

FLSmidth high density thickeners optimise recoveries at DRC copper-cobalt mine

FLSmidth says it has delivered a thickener solution to help double production rates at one of the world’s largest copper and cobalt producers in the Democratic Republic of the Congo (DRC).

The order for the solution, which included six of FLSmidth’s high density thickeners, was placed in 2020, with delivery now completed.

The mine already had FLSmidth thickeners on site, with the company’s proposal for the mine’s expanded requirements  based on test work to confirm the characteristics of the material to be treated, according to FLSmidth General Manager Projects and Account Sales, Howard Areington.

“The tests confirmed that we could use a similar design to what we had installed on the mine some years previously,” he says. “This solution included six counter current decantation (CCD) thickeners and one pre-leach thickener, each measuring 31 m in diameter.”

These units deliver high solids underflow to optimise the recovery of dissolved metals, according to FLSmidth. In addition to the steeper floor slope, these thickeners were designed with a high torque ring gear drive design, with high tolerances that make for minimal maintenance over long periods of time, the company says.

“Our high density thickener design ensures consistently high underflow densities which allows the operator to sustain high production rates and better recoveries,” Areington says.

These CCD thickeners are manufactured from LDX2101 duplex stainless steel. This provides mechanical benefits without compromising chemical resistance, allowing the mass of each unit to be reduced, the company explained. The pre-leach thickener, which was not exposed to corrosive conditions, is constructed from carbon steel.

“We also designed and supplied five impurities removal thickeners, which are high rate thickeners, also in LDX2101 stainless steel,” Areington says. “The sizes of these units ranged from 20 to 30 m in diameter.”

Fabrication of the equipment was carried out in South Africa while accommodating the demands of the COVID-19 lockdown, which required careful planning and flexibility. With components and platework delivered to site, the welding and construction was conducted by the mine with installation assistance from FLSmidth and its agent in the region.

Nickel 28 claims industry ‘first’ carbon neutral status

Nickel 28 Capital Corp has become what it believes is the first carbon neutral refined nickel-cobalt producer in the world through a transaction involving the purchase of 52,500 carbon offsets on the Verra Registry.

The carbon offsets will, it says, fully offset Nickel 28’s anticipated 2021 attributable greenhouse gas (GHG) emissions from the Ramu integrated nickel-cobalt mine and refinery in Papua New Guinea (pictured), an asset it owns 8.56% of.

Anthony Milewski, Chairman of Nickel 28, said: “We are incredibly excited to be one of the first, if not the first, producers of refined nickel and cobalt in the world to fully offset its carbon footprint.

“We feel strongly that each of us has an obligation to do our part personally and professionally to help stave off the negative impacts of climate change. As the world pivots to electric vehicles and other means of decarbonisation, it is imperative that the critical basic materials fuelling the transition have the minimum possible impact on the environment.”

On February 9, Nickel 28 announced it had completed an independent analysis on GHG intensity for the Ramu nickel-cobalt operation, confirming the operation is one of the lower GHG emitters in the nickel industry. Ramu’s average GHG intensity has been calculated at 15.6 t of carbon dioxide equivalent per tonne of nickel (15.6 tCO2e/t Ni) in mixed hydroxide product. This compared favourably with a nickel industry average GHG intensity of 36.6 tCO2e/t Ni as calculated by Wood Mackenzie, Nickel 28 said.

The company says it will continue to introduce greater environmental, social and governance transparency with respect to its assets in response to investor and industry trends.

“In addition to GHG emission reporting, Nickel 28 will be providing further clarity with respect to other key measures such as health and safety statistics, community investment, energy and water usage, rehabilitation, and land reclamation,” it said.

Nickel 28 currently holds an 8.56% joint-venture interest in the Ramu operation, with Ramu operated by the Metallurgical Corporation of China, which, along with its partners, owns an 85% interest in Ramu.

Ramu produced 33,659 t of contained nickel in mixed hydroxide product in 2020, compared with 32,722 t in 2019.
