**New paper** Microbial mine-site offsets. Last (for now) in a series of bio-mineral carbonation papers set in South African diamond mines. This paper focuses on the use of biofilms and kimberlitic material from the Venetia Diamond mine to accelerate mineral carbonation in Fine Residue Deposit kimberlite (the smallest fraction of mine 'waste' of the diamond mining process). This paper tracks experiments from lab to field scale - with some pretty cool results.

New open access paper alert! We explore the relationship between stable dissolved black carbon and DOC - revealing initial evidence that legacy mining infrastructure may act as a source of geogenic black carbon, decoupling DBC and DOC in some cases. https://lnkd.in/ef_gQ5vS

I recently gave a presentation to the Board of a gold mining company about #mining in 2035... We covered new methods of mining - heavy focus on using AI and other digital technologies - but I also talked about how companies are measuring the gold content in plant leaves to determine whether there are potential deposits to explore. So my gardener alter ego was delighted to see the latest investment (from ARPA-E) in #phytomining emerge - this is where plants extract minerals from the earth and we extract them directly from the plant. Of the 350,000 known plant species, 750 are “hyperaccumulators” that readily absorb sky-high amounts of metals and incorporate them into their tissues. Hyperaccumulator plants also concentrate the mineral and help soil clean up - focus currently is on Nickel for batteries. And ARPA-E has promised to fund up to $10m for Phytomine research.   I am a complete fan of DARPA and ARPA-E (the US government defense advanced research projects agency and the energy ) that has been funding much research that has reached us over the years. I am a huge supporter of free markets. But I am very conscious that government has a massive (misunderstood) influence (monetary and otherwise) on new inventions and innovations. I think of the millions that the NIH has poured into the orphan drug programme that is making money for the pharma companies. Or the fact that GPS and Siri are direct descendants of DARPA funded programmes. For more examples, read Mariana Mazzucato 'The Enterpreneurial State'. And think twice before you say "cut governmental research spending" because private equity does that ...

Sustainable mining may be closer than we think! With the development of phytomining, plants can now mine metals through their roots. This innovative practice not only captures minerals like nickel more efficiently, but also helps to capture carbon dioxide from the atmosphere. As we face a future with a growing need to mitigate our ecological footprint, embracing sustainable mining practices like phytomining is more important than ever.

I am pleased to announce the publication of our latest paper published in Science of the Total Environment. The study entitled "Impact of climatic seasons on the dynamics of carbon, nitrogen, and mercury in soils of Brazilian biomes affected by gold mining" explores the effects of gold mining in Brazilian biomes and how climatic seasons influence the availability of mercury and the carbon retention in the soil. Gold mining can reduce soil carbon stocks by up to 50% and increase mercury availability by 70%. The impact of weather seasons, particularly dry season, exacerbates carbon loss and mercury mobilization in the soil. We estimate a loss of up to 0.019 Gt of carbon in Brazilian mining areas.

Hello Linked In Innovators! Climate change is changing how we design #desalination plants, especially for #responsiblemining companies. 💦⛏️ Learn from Black & Veatch's desalination guru, Srinivas (Vasu) Veerapaneni, who is presenting on desalination trends at the upcoming 12th International Congress on Water Management in Mining and Industrial Processes in Chile, 4-6 September organized by Gecamin. Without water there is no mining. As #ResponsibleMining companies reduce withdrawal impacts on local communities and explore desalination options to secure water supply for their mining operations, Vasu will explain how #ClimateChange is impacting seawater quality and, in turn, changing how the industry is designing pre-treatment water process - more algae blooms, more jelly fish, more suspended solids. All of these factors mean developers need to actively consider a selection of pre-treatment processes to ensure reliable operations and optimize costs. Connect with Vasu during the event to learn more!

Nancy Perreault, who leads the environmental microbial processes team in our Energy, Mining and Environment Research Centre, was a speaker at the recent Québec Mines + Énergie conference. The conference focused on implementing sustainable solutions to current issues in the mining sector. Dr. Perreault spoke about the development of new biotechnological approaches, primarily aimed at reducing greenhouse gas emissions and energy consumption compared to traditional extraction techniques. She also spoke about building and strengthening the supply chain for critical minerals to support Canada's energy transition. Her presentation provided an overview of mining biotechnologies and covered a range of topics, including: - Advances in gold extraction using biocyanidation – a technique that can enable in situ extraction - Faster, more cost-effective options for the biological extraction of critical minerals from secondary resources - Ways to optimize mining bioprocesses to make them more stable and robust Learn more about our capabilities: https://ow.ly/StX350QpzZ4 #NRCMiningTechnology

Pyrite May Be Known as Fool’s Gold, but It Actually Contains a Kind of Green Gold–Lithium Appalachian mining country seems an unlikely place to find a potential breakthrough in renewable energy, but samples of mine tailings in West Virginia have turned up plenty of lithium contained inside fool’s gold. The team of scientists behind the discovery described it as “previously unheard of” and they hope that lithium extracted this way could […] The post Pyrite May Be Known as Fool’s Gold, but It Actually Contains a Kind of Green Gold–Lithium appeared first on Good News Network.

A International System Dynamics Conference 2024 terá a participação de Karim Chichakly, membro do Capítulo Brasileiro, que apresentará o trabalho "An Ecosystem Model of Post Mining Land Use", com co-autorias de Mayra Zevallos e Paul Hesketh, e discutirá a pesquisa sobre "Reducing Veteran Suicide Risk in the USA", com co-autorias de David Rozek e Katherine Dondanville. Veja o resumo de: An Ecosystem Model of Post Mining Land Use Returning mined land at closure to its pre-mining land use is not always desired or possible due to alterations of the landscape and socioeconomic context. Post Mining Land Use (PMLU) is often promoted as a solution, however significant effort is required in developing PMLU options with different land uses providing widely different outputs. The mine site can be a value driver by providing resources (among these water, waste and land) that can springboard these activities. To create a sustainable system, a holistic approach is needed to understand the whole business ecosystem and the inter-relationships between different PMLU activities and how these activities reinforce each other (generation of wastes, supply of energy, use of water and benefits developed), e.g., the inter-relationship between land, cropping for energy generation, irrigation of the crop with mine water and the impact on biomass generated and economic activity developed (measured as jobs). The ecosystem model developed simulates processes across value streams over the life of an asset, identifies opportunities and gaps in knowledge, improves the understanding of the business ecosystem, and supports investment decisions.
