Arca’s carbon sequestration tech gaining traction with mining company engagements

Arca has announced that it is working with producers of nickel to advance carbon dioxide removal at mine sites on three continents, having engaged with Vale, Talon Metals, Poseidon Nickel, NickelSearch and Blackstone Minerals.

The company, which calls itself a leader in carbon mineralisation, works globally with nickel mine developers and operators to capture and permanently store CO2 in mine tailings using its technology.

Arca is developing and commercialising a portfolio of technologies that help mining companies measure, maximise and monetise the carbon sequestration potential of their mining by-products. Arca’s patent-pending mineral activation technology uses high-intensity bursts of energy to transform and disrupt the mineral lattice structure of magnesium-rich minerals, increasing both the rate and capacity for CO2 capture and permanent storage.

With material from its mining company partners, Arca says it has achieved never-before-seen rates of air capture and capacity for CO2 storage, operating at atmospheric air temperature and pressure.

Arca can work with legacy (closed) mines, junior (under-development) mining companies, as well as existing mine operations of any size, and says it is currently working with mining companies in key mining jurisdictions such as Canada, Australia, the US and Southeast Asia.

Today, Arca announced it is working with the global mining major Vale, the Australia-based juniors Poseidon Nickel and NickelSearch, and Blackstone Minerals.

Arca is also working with Talon Metals which, in a joint venture with Rio Tinto, is developing the US’ only high-grade nickel resource for the domestic battery supply chain.

“Talon and Arca are working on transformational change in mining and mineral processing,” Todd M Malan, Head of Climate Strategy, Talon Metals, said. “Our partnership is focused on showing how ‘waste’ from conventional nickel processing can be harnessed to store carbon that has been removed from the atmosphere or captured in industrial processes. This ‘waste-as-carbon-sink’ approach has further potential for reuse in building materials, thus significantly reducing the amount of waste that needs to be stored as compared to present day legacy nickel processing.”

Professor Greg Dipple, co-Founder and Head of Science at Arca, said: “Arca is helping mining companies understand the potential for mineralisation of their resources, design how that potential should be realised, and then advance to actual project development. Our mineral activation technology significantly accelerates the natural process of carbon mineralisation using mine tailings from ultramafic rocks. This helps these companies transform their tailings into industrial-scale direct air capture and storage facilities, transforming mine waste into a valuable new resource and climate solution.”

Arca has been recognized with a $1 million XPRIZE Milestone Award for Carbon Removal, a Foresight50 Award as one of Canada’s most investable cleantech ventures, and an SDTC Seed Fund grant.

Dr Dipple will be speaking in Perth, Australia, about Arca’s technology at the CSIRO symposium on locking carbon in minerals on June 20.

Electric Mine Consortium partners with AWS on world-first mine decarbonisation platform

Australia’s Electric Mine Consortium (EMC), made up of some of the world’s leading mining and service companies, has announced it is working with Amazon Web Services (AWS), an Amazon.com company, to accelerate the electrification of mine sites globally.

Announced at AWS Summit 2022, EMC is using AWS’s depth and breadth of services, including machine learning, business intelligence and storage, to build the world’s first mining data platform, to capture real-time information on mine decarbonisation from sites globally.

To drive decarbonisation, mining companies can use the platform to measure energy storage levels and electrical infrastructure use from global mine sites to accelerate the creation of a cleaner, more electrified future in mining, EMC said.

Co-founder of the EMC, Graeme Stanway, says the platform can help enable EMC members to share sustainability insights and analyse the outcomes of adopting electrified mining infrastructure and sustainable operations.

“The way we generate, store and harness energy around the globe is changing drastically,” Stanway said. “EMC’s collaboration with AWS will help see us at the forefront of this change, driving the mining industry’s electrification at scale.”

Stanway said the industry is crying out for tools to decarbonise due to tightening government emission reduction targets, increasing environmental, social and governance pressure, and the industry being responsible for 7% of the greenhouse gas emissions globally.

“Like the electric vehicle industry, electric mines are the future” Stanway said. “Not only can they be safer through the eradication of diesel particulates, pollution, noise and vibrations, they can also be more targeted, precise and effective when it comes to mining, and yield stronger results than traditional mines with minimal ground disturbance.”

As part of the initiative, EMC created a “data lake” using Amazon Simple Storage Service (Amazon S3), a cloud object storage service, that can securely store thousands of datasets from the consortium’s mines, including data on energy consumption and renewable energy infrastructure output.

EMC can then clean the data and run data pipelines using AWS Step Functions, a low-code, visual workflow service; AWS Glue, a serverless data integration service; and AWS Lambda, a serverless, event-driven compute service. AWS Glue can provide EMC with data catalogue functionality, and AWS Lake Formation, a service that makes it easy to set up a secure data lake in days, can deliver security and access control.

Amazon QuickSight, a business intelligence service (screenshot pictured), can allow everyone in the consortium to explore and understand mining data through user-friendly interactive dashboards that identify efficiency practices that may reduce emissions, according to EMC.

Also, using Amazon SageMaker, a fully managed service to build, train, and deploy machine learning models, EMC can train machine-learning models to predict energy usage spikes at mines and track the carbon efficiency of deploying sustainable energy infrastructure.

Sarah Bassett, Head of Mining and Energy, Australia at AWS, said: “Data capture and analysis is essential to mining operations, and AWS is helping consortium members to share their critical datasets and collective insights to drive the digitisation and evolution of the industry. I am excited to be collaborating with the EMC and its consortium members to improve the design of mines globally and accelerate the industry’s journey to decarbonisation on the global scale.”

The EMC is a growing group of over 20 mining and service companies. These companies are driven by the imperative to produce zero-emission products for their customers and meet mounting investor expectations. Thus, the objective of the EMC is to accelerate progress toward the zero-carbon and zero-particulate mine through:

  • Resolving key technology choices;
  • Shaping the supplier ecosystem;
  • Influencing policy; and
  • Communicating the business case

The EMC is emerging as a key vehicle for the decarbonisation of the mining industry, particularly for underground operations, and will remain responsive to the rapidly changing external environment.

Members include OZ Minerals, Newcrest Mining, Gold Fields, IGO, South32, Blackstone Minerals, Evolution Mining, Barminco and Iluka Resources.

GR Engineering to deliver feasibility study on Ta Khoa nickel project

Blackstone Minerals Ltd has appointed GR Engineering Services Ltd (GRES) as the primary consultant in the delivery of the Upstream Definitive Feasibility Study (DFS) for its Ta Khoa nickel project (TKNP), in Vietnam.

As the primary consultant, GRES will focus on the delivery of major workstreams including process infrastructure, metallurgical test work and co-disposal tailings storage. GRES will also coordinate, collaborate with and collate information from other key workstreams including mining studies, Blackstone said.

Blackstone says GRES has a proven track record and relevant experience to deliver the TKNP DFS, having completed a DFS for OZ Minerals on its West Musgrave nickel project and completed engineering, procurement and construction work on the Cosmos Expansion project (Western Areas Ltd), the Nova Nickel project (now IGO Ltd), the Cosmic Boy nickel project (Western Areas) and the Sinclair nickel project (now Northern Star Resources Ltd).

Further, GRES provides full life-cycle engineering services from feasibility studies through to delivery of projects under both EPC and engineering, procurement and construction management models, Blackstone said.

Scott Williamson, Blackstone’s Managing Director, said: “GRES adds to an already impressive team of engineers that are contributing to the design and development of the Ta Khoa Project.

“Blackstone continues to de-risk its development strategy both from a technical and funding perspective, and looks forward to updating the market as we take key steps towards a final investment decision.”

The TKNP is 160 km west of Hanoi in the Son La Province of Vietnam and includes an existing modern nickel mine built to Australian standards, which is currently being used to process nickel ore delivered by the underground bulk sample program, the company said. The Ban Phuc nickel mine successfully operated as a mechanised underground nickel mine from 2013 to 2016.

In February 2022, Blackstone completed a prefeasibility study for the TKNP, and presented this on an integrated basis with the proposed Ta Khoa Refinery (TKR) development. The TKR is being designed to have a refining capacity of 400,000 t/y, with feedstock provided from a combination of concentrate from the TKNP and third-party feed sources.

Polymathian, SimGenics, Simulation Engineering Technologies, MathWorks, First Mode to tackle electric mine simulation tasks

Five teams have been selected to join the Think & Act Differently (TAD) ideas incubator, powered by OZ Minerals and Unearthed, tasked with developing and testing an open architecture simulation platform to develop electric mine designs, with the goal to achieve zero scope one emissions.

Last September, the Electric Mine Consortium launched the Electric Mine Simulation crowd challenge in partnership with the (TAD) ideas incubator, noting that electrification of mine sites remained a critical step change needed for the mining industry to achieve a zero-carbon future.

“Switching to electrified solutions and renewable energy represents a transformational shift that will change the way mines are designed,” OZ Minerals said. “This challenge is about using simulation to understand the impacts of electrification on mine design, infrastructure and energy management.”

The crowd challenge closed in November last year and attracted 179 participants from 36 countries, resulting in 23 submissions. Five teams have now been selected to join the TAD incubator where they will be supported to develop and test their simulations.

Finalist teams include:

  • Polymathian – Colin Eustace, Michael Dallimore, Steven Donaldson and Mitchel Grice are experts in solving complex planning and scheduling problems for the industry, OZ Minerals said. Their solution is to provide a widely used scalable simulation model platform to model large and complex operations, from mining and processing to full supply chain operations;
  • SimGenics – Abrie Venter and Kobus Viljoen are using a software platform that can integrate continuous and discrete-event simulation tools from multiple vendors into one solution;
  • Simulation Engineering Technologies – Jaco Botha, Henk Jenkinson, Fredrik Sundqvist and Marco Agas are the team behind a mine simulator (SimMine®) that allows for the construction of a complete mine simulation, including development, production and ore handling systems;
  • MathWorks – Wilco Volwerk, Peter Brady, Ruth-Anne Marchant and Sam Oliver are using a mathematical computing software that can be used to model dynamic, discrete and continuous processes with multiple time scales to create a mine simulation framework; and
  • First Mode – Aidan Morgan, Jan Haak and Clara Sekowski represent a creative engineering company, using modelling and simulation to inform design decisions and optimise the use of technology.

The teams will work together to explore and develop concepts for the development of an open architecture simulation platform to develop electric mine designs, with the goal to achieve zero scope one emissions. A use case for testing the value of simulation will be provided by OZ Minerals’ copper-gold mine, Prominent Hill, with further use cases developed in collaboration with the Electric Mine Consortium member companies.

The TAD Incubator program is a supportive environment that includes funding, technical mentoring, opportunities for collaboration, capability uplift and access to mining data and mining operations, OZ Minerals said. The teams will be supported by mining business improvement specialists from Imvelo, Sharna Glover and Alan Bye and Simulation SME Luigi Barone, an internationally recognised expert in artificial intelligence.

Brett Triffett, OZ Minerals’ Transformation Technologist, said: “This challenge will help us learn about the power of simulation together with some really talented and collaborative people, as we accelerate progress towards a fully electrified zero carbon zero particulate mine. The benefit of crowdsourcing, particularly in an area where ideas may come from outside our traditional mining networks, is that we can scour the globe to find start-ups, academics and individuals that we would not have otherwise had encountered.”

Multiple mining companies from the EMC will be able to collaborate on the outcomes of this experiment and we’re excited to see what we can learn about the process as well as the technology. The teams will work together over a three-month period to develop simulation concepts.

OZ Minerals, IGO South 32, Blackstone Minerals, Evolution Mining, Barminco and Gold Fields have committed to significantly reducing their carbon footprint. These seven mining companies, along with a number of partner companies, have come together to form the Electric Mine Consortium, a collaborative group seeking to accelerate progress towards a fully electrified zero carbon and zero particulate mine.

The TAD incubator is powered by OZ Minerals and is focused on themes that prioritise social and environmental responsibility for the future of mining.
