The Think & Act Differently (TAD) incubator, powered by BHP, has announced its support for a new cohort that has come together to develop an innovative technology roadmap for in-situ and alternative extraction options, the company says, lower the impact of mining and processing.

In collaboration with its partner, Unearthed, the TAD Cohort was curated through a venture-style selection process, which also involved selection of members from the TAD Ecosystem.

This cohort is supported and funded by BHP, Boliden, Rio Tinto, South32 and IGO, as part of the TAD Collaboration that is commited to unlocking new technologies and reimagining lower impact mining and processing to find value in overlooked resources.

The TAD Cohort comprises a diverse group of companies ready to apply new ways of thinking to in-situ recovery. It includes:

  • Auric BioRecovery: using bio recovery processes to release metal from tailings;
  • Clean & Recover: ElectroClear recovery of water from acid mine drainage;
  • Destiny Copper: Using high activation potential and chemistry to eliminate electricity requirements for plating copper;
  • Draslovka: A ‘green’ recyclable lixiviant, selective in leaching base and precious metals from host minerals (pictured in a test lab above);
  • Eden GeoPower: Rock preconditioning technology to enable in-situ solution mining;
  • Ekion: Enabling the in-situ extraction of metals using electrokinetics;
  • EnviroGold Global: Clean-technology process for metal recovery from sulphide mine tailings and smelter residues; metal recovery includes strategic, critical, base and precious metals;
  • LeadFX: Metal recovery with CO2 capture;
  • Loop Hydrometallurgy: Clean technology unlocking copper, rare earth elements and other metals from tailings and concentrates;
  • Muon Vision: Cosmic ray sensing for tailings and heap leach monitoring; and
  • Precision Periodic: Enabling industrial scale chromatography using novel filtration media to recover and concentrate elements in mining applications and treatment of wastewater.

Draslovka Holding a.s., a Czech family-owned global leader in cyanide-based specialty chemicals, says its glycine leaching technology has been selected to be part of the OZ Minerals’ Think & Act Differently (TAD) incubator and Waste-to-Value Challenge.

The latter challenge, announced back in December, sees Rio Tinto and Boliden working in collaboration with OZ Minerals to eliminate, minimise, reuse or find new value in mine tailings and ultimately reduce the global carbon footprint of the mining industry. Draslovka said: “The Waste-to-Value Challenge aims to unlock innovative technologies for managing tailings, helping the mining industry to reduce risk while extracting more of the materials the world needs from what was previously regarded as waste for the energy transition at large. Benefits that the initiative hopes to deliver include lower emissions and reduced waste.”

Draslovka offers a range of sustainable solutions to the global mining industry, and its glycine leaching technology (branded as its GlyLeach™ and GlyCat™ processes) represents the best environmentally-friendly alternative to traditional acid and cyanide leaching, according to the company. Due to its selectivity over gangue minerals and the recyclability of glycine, its use enables the recovery of both base and precious metals from lower-grade resources like tailings. This leads to a more sustainable production process and improved economics that are desperately needed to close the looming critical metal supply deficit.

Ivor Bryan, Draslovka’s Mining Innovation Director, said: “I am proud that Draslovka has been invited to participate in the Waste-to-Value Challenge with forward looking companies that understand the need to reimagine solutions for the mining industry. This aligns with our ambition to become the leading supplier for innovative and sustainable solutions for the wider mining industry.”

Speaking to IM on the sidelines of the recent Resourcing Tomorrow conference, in London, Bryan said the company was 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.

OZ Minerals, Boliden and Rio Tinto to collaborate on tailings initiative

OZ Minerals, Boliden and Rio Tinto have agreed to collaborate to unlock new and innovative technologies for managing tailings, helping the mining industry to further reduce risk while extracting the materials the world needs for the energy transition from what was previously regarded as ‘waste’, they say.

Under the umbrella of the Think & Act Differently (TAD) incubator initiative, the three companies will fund and support innovators who are working to reimagine mining and processing to eliminate, minimise, reuse or find value in mine tailings. The three companies will also collaborate on other selected innovations to pursue improved productivity while delivering benefits such as lower emissions and reduced waste.

The collaboration will support innovators by providing materials, funding, technical guidance and the potential for field trials at mine operations, the companies said. Innovators will retain ownership of their intellectual property rights, with a licence to use those rights granted to the companies that support them.

Michelle Ash, OZ Minerals’ Technology Executive, said: “We can accelerate technology much faster by working together and this is an example of how the industry can collaborate to support technology development. We hope this way of working and supporting innovators provides a model that can be replicated because accelerated technology development is likely to have a positive impact on our industry and society.”

Joanna Lindahl, Boliden Mines’ Sustainability Director, added: “By collaboration on generic challenges for the mining industry in a pre-competitive setting we will be able to make progress faster and more resource efficient. For the inventors and startup companies in the TAD incubator, it is also an excellent opportunity to get insights and business understanding from several different mining companies. We are very much looking forward for this collaboration and hope to find new opportunities to strengthen the industry in the future.”

Mark Davies, Chief Technical Officer for Rio Tinto, said: “It isn’t very often that competitors come together to collaborate on industry-critical work. One such area historically has been health, safety and environment, where we learned that sharing leading practices boosts our collective performance. We think collaborating on tailings management capability improvement could have a similar, industry-wide impact. We’re excited to be partnering with Boliden and OZ Minerals through the TAD program.”

The Think & Act Differently program, powered by OZ Minerals, works towards building an ecosystem of partners who will explore and accelerate themes that prioritise social and environmental responsibility for the development of the modern mine, the company says.

Novamera and OZ Minerals to take surgical mining concept forward with new MoU

Novamera Inc and OZ Minerals have entered into a Memorandum of Understanding (MoU) that, they say, provides a basis of common understanding to support the creation of a “collaborative innovation relationship” between the parties.

The two companies share a desire to unlock value in stranded mineral assets, transform the mining project lifecycle and enable the world’s raw material needs to be met responsibly, equitably and sustainably, they said. To that end, the partnership plans to engage in certain activities including, but not limited to, the following:

  • Participation by OZ Minerals in the Canada Mining Innovation Council (CMIC) Consortium of Mining Companies to trial Novamera’s near borehole imaging tool (NBIT) at various project sites later in 2022;
  • Assess the potential of deploying Novamera’s technology within OZ Minerals’ project portfolio;
  • Collaboratively evaluate potential project opportunities; and
  • Co-develop collateral to articulate the operational experience and value proposition associated with Novamera’s technology.

The agreement follows Novamera being named as one of seven companies in OZ Minerals’ ‘Scalable and Adaptable’ mining cohort to work together to explore flexible mine design, in September. The challenge was run as a partnership between OZ Minerals’ Think & Act Differently Incubator, Canada-based Inspire Resources and Unearthed.

Dustin Angelo, President and CEO of Novamera, said: “Since last September, we have been working with the Think & Act Differently team on the Scalable & Adaptable Mining Challenge. Over that period of time, we realised we share common goals and ideas on the direction of the mining industry and where to unlock value. The MoU will allow us to focus our efforts collectively and begin to leverage our individual core competencies to create a tremendous amount of value for each of our companies.”

Katie Hulmes, General Manager Transformation at OZ Minerals, added: “The Novamera technology can enable surgical mining. This approach has the potential to operate with less waste, water, energy and a smaller footprint. We look forward to working with Novamera as part of the CMIC Consortium and various internal projects.”

Novamera, through surgical mining, has set out to adapt a combination of drilling and imaging techniques already proven in the oil & gas industry for the narrow-vein mining sector, providing the technical and economical means to mine steeply dipping narrow-vein orebodies with the reduced footprint disturbance modern mining operations require.

Last year it carried out a proof of concept trial of the technology at the Signal Gold-owned Romeo and Juliet deposit in Newfoundland, Canada, which was designed to test the entire surgical mining system and process, which is made up of three steps. This includes drilling a pilot hole with a standard NQ-sized diamond core rig and sending imaging tools down through the core barrel on wireline; bringing in a large-diameter drill to drill to depth following the trajectory provided by the imaging tool and extracting the cuttings; and backfilling the holes thereafter.

Angelo told IM recently that the company had assembled a consortium of companies looking to co-fund a field trial of the company’s minimum viable product version of the NBIT (the version used at Romeo and Juliet, pictured), which is the key enabling technology within surgical mining, through CMIC.

As part of the Hydrogen Hypothesis challenge, seven teams have been selected to take part in the OZ Minerals’ Think & Act Differently (TAD) accelerator program.

The focus of the challenge, launched at the end of March, was to identify experiments that can demonstrate the safe and effective use of hydrogen in a mining context, with the aim of providing OZ Minerals insight into how hydrogen can be used to support zero or low carbon processes.

It was underlined by the miner’s strategic aspiration to eliminate Scope 1 emissions and strive to systematically reduce Scope 2 and 3 emissions across its value chain.

There were 158 participants in the OZ Minerals and Unearthed Hydrogen Hypothesis challenge, from 35 countries.

Brett Triffett, OZ Minerals’ Transformation Technologist, said: “The mining sector has the opportunity to leverage the progress made in other sectors and explore the use of hydrogen technology in its operations.

“The finalist teams were chosen because they have proposed ideas that have the potential to demonstrate the value hydrogen technologies and applications could create for our industry.

“These teams also demonstrated their willingness to work and learn together with each other and OZ Minerals. The OZ Minerals TAD incubator acceleration program is designed to create as much mutual value as we possibly can, rather than just transacting an experiment for funding.”

The program, according to Triffett, includes frequent capability uplift sessions on a range of topics so participants come out with something more than just a funded experiment.

“Many of the finalist teams are not from the mining industry and are keen to learn more about how the industry works,” he added.

These insights are embedded through regular insights panels with members of OZ Minerals’ broad ecosystem. They also come together with a technical mentor to gain valuable feedback on the technical aspects of their work with one another.

The teams selected are

  • Avid Group (Aaron Teo) – Hydrogen powered lighting towers;
  • Carbon 280 (Mark Rheinlander) – Hydrilyte storage system – safe hydrogen transport and storage at atmospheric temperature and pressure;
  • Carnot (Francis Lempp) – Ultra efficient ceramic engine;
  • Fly H2 Aerospace (Mark Van Wyk) – Hydrogen-powered drone;
  • OZ Minerals (Steve Day) – Hydrogen highway;
  • Supercritical (Luke Tan) – High pressure electrolyser; and
  • Yakum Consulting/Queens University (Yeonuk Choi) – Produce clean metal products from concentrate using green hydrogen.
