项目摘要

Cobalt is an essential element for modern world. Its use in metal alloys, rechargeable batteries, electronics and high-value chemicals make it critical for a low-carbon society. Cobalt has the largest global market value of any of the individual e-tech elements (US$2.1 billion in 2013). Cobalt is largely recovered as a by-product from the mining of other major metals and as a result, cobalt has not been the focus of study in ore-forming systems on its own. To address this knowledge gap we propose a systematic geological, geochemical and mineralogical approach to understanding the residence of cobalt in a range of important current and future ore minerals in diverse geological environments. A specific focus for this study are deposits forming in the Critical Zone of the Earth's crust where biological activity and weathering coincide and where cobalt is redistributed into forms where innovative bioleaching could change the way deposits are processed. Using new knowledge gained from the study of natural biological systems, advanced bioleaching techniques will be systematically applied to a range of deposits formed in the Critical Zone. Bioleaching also has great potential for reduced, sulfide-rich ores, particularly complex sulfide and often arsenic-rich ore-types where significant bioleaching has not yet been tested. This COG3 proposal builds on our catalyst grant which developed a multi-institute and multi-investigator consortium with internationally recognised expertise across the geosciences including geology, geochemistry, mineralogy, microbiology and bioprocessing based in leading UK academic institutes: Herrington (NHM), Schofield (NHM), Johnson (Bangor), Lloyd (Manchester), Pattrick (Manchester), Coker (Manchester), Roberts (Southampton), Gadd (Dundee), Glass (Exeter), Mosselmans (Diamond) and Kirk (Loughborough), with in-depth expertise on geology, geometallurgy and geomicrobiology applicable to developing recovery strategies for cobalt from natural deposits. This group is underpinned by the Partners including the major mining companies Glencore, FQML and KGHM; a mid-tier European-based mining company Oriel; a junior UK-based mining SME Brazilian Nickel, an internationally accredited commercial research laboratory RPC and finally the Cobalt Development Institute representing the cobalt industry throughout the supply chain. They have all pledged to engage with the project, some through direct involvement in research activities, some with financial support for research and training and others by facilitating access to natural deposits and datasets. Further support comes from research colleagues at CSIRO in Australia. Specific research will be delivered through a series of work packages which will address: 1) Geology and mineralogy of cobalt in natural systems; 2) Natural biogeochemistry of cobalt; 3) Bioprocessing of cobalt and development of new products; 4) Improving the cobalt supply chain through integrated studies and dialogue with stakeholders representing the supply chain. This research directly addresses the NERC Security of Supply of Mineral Resources (SoS Minerals) initiative Goals 1 & 2 with a fundamental aim to recognise the mineral residence and chemical cycle of cobalt (Goal 1) and provide geometallurgical information that will facilitate new opportunities for improvements to current recovery, minimising waste through geometallurgy; and thoroughly testing innovative, benign bioleach technologies for the extraction and downstream bioengineering of novel cobalt products (Goal 2). Through the collaboration of the PIs, Co-Pis, Partners and the development of PDRAs and PhDs, the program will produce high impact scientific publications for the international literature, highly significant public outreach and education on behalf of the NERC SoS programme and establish the UK COG3 consortium as a world leader in research into innovative cobalt recovery from natural mineral deposits.

钴是现代世界必不可少的元素。它在金属合金、充电电池、电子产品和高价值化学品中的应用使其成为低碳社会的关键。在所有单个电子技术元素中，钴的全球市场价值最大(2013年为21亿美元)。钴主要是作为开采其他主要金属的副产品回收的，因此，钴本身并不是成矿系统研究的重点。为了解决这一认识差距，我们提出了一种系统的地质、地球化学和矿物学方法，以了解钴在不同地质环境中一系列当前和未来重要矿石矿物中的驻留情况。这项研究的一个具体重点是在地壳的临界区形成的矿床，在那里生物活动和风化作用同时存在，钴在那里重新分布成创新的生物浸出可以改变矿床处理方式的形式。利用从自然生物系统研究中获得的新知识，将系统地将先进的生物浸出技术应用于临界区形成的一系列矿床。生物浸出对于还原的富含硫化物的矿石也有很大的潜力，特别是复杂的硫化物，而且往往是富砷的矿石类型，在这些类型中，重大的生物浸出尚未得到测试。COG3建议建立在我们的催化剂赠款的基础上，该联盟发展了一个多研究所和多研究员的财团，拥有国际公认的地质学、地球化学、矿物学、微生物学和生物加工方面的专业知识，这些专业知识设在英国领先的学术机构：赫灵顿(NHM)、斯科菲尔德(NHM)、约翰逊(班戈)、劳埃德(曼彻斯特)、帕特里克(曼彻斯特)、科克(曼彻斯特)、罗伯茨(南安普顿)、GADD(邓迪)、格拉斯(埃克塞特)、莫塞尔曼斯(钻石)和柯克(拉夫堡)，在地质、几何金刚和地球微生物学方面拥有深厚的专业知识，适用于制定从天然矿床中回收钴的策略。该集团的基础是合作伙伴，包括主要的矿业公司Glencore、FQML和KGHM；一家总部位于欧洲的中端矿业公司Oriel；一家总部位于英国的初级采矿中小企业巴西镍公司；一家国际认可的商业研究实验室RPC；以及最后一家代表整个供应链钴行业的钴发展研究所。他们都承诺参与该项目，一些是通过直接参与研究活动，一些是通过为研究和培训提供财政支持，另一些是通过便利获得自然沉积物和数据集。进一步的支持来自澳大利亚CSIRO的研究同事。将通过一系列工作包开展具体研究，这些工作包将涉及：1)自然系统中钴的地质和矿物学；2)钴的天然生物地球化学；3)钴的生物加工和新产品的开发；4)通过综合研究和与代表供应链的利益攸关方对话，改善钴供应链。这项研究直接涉及NERC矿产资源供应安全(SOS Minerals)倡议目标1和2，其根本目的是认识钴的矿物居留和化学循环(目标1)，并提供几何冶金信息，以促进改进当前回收的新机会，通过几何冶金将废物降至最低；以及彻底测试创新的、良性的生物浸出技术，用于新型钴产品的提取和下游生物工程(目标2)。通过PIS、Co-PIS、合作伙伴的合作以及PDRA和博士的开发，该计划将代表NERC SOS计划为国际文献、非常重要的公共宣传和教育制作具有高度影响力的科学出版物，并将英国COG3财团建立为从天然矿藏中创新回收钴的研究的世界领先者。
