Rare earth elements (REE) are the headline of the critical metals security of supply agenda. All the REE were defined as critical by the European Union in 2010, and in subsequent analysis in 2014. Similar projects in the UK and USA have highlighted 'heavy' REE (HREE - europium through to lutetium) as the metals most likely to be at risk of supply disruption and in short supply in the near future. The REE are ubiquitous within modern technologies, including computers and low energy lighting, energy storage devices, large wind turbines and smart materials, making their supply vital to UK society. The challenge is to develop new environmentally friendly and economically viable, neodymium (Nd) and HREE deposits so that use of REE in new and green technologies can continue to expand.The principal aims of this project are to understand the mobility and concentration of Nd and HREE in natural systems and to investigate new processes that will lower the environmental impact of REE extraction and recovery.By concentrating on the critical REE, the research will be wide ranging in the deposits and processing techniques considered. It gives NERC and the UK a world-leading research consortium on critical REE, concentrating on deposit types identified in the catalyst phase as most likely to have low environmental impact, and on research that bridges the two goals of the SoS programme.The project brings together two groups from the preceding catalyst projects (GEM-CRE, MM-FREE) to form a new interdisciplinary team, including the UK's leading experts in REE geology and metallurgy, together with materials science, high/low temperature fluid geochemistry, computational simulation/mineral physics, geomicrobiology and bioprocessing. The team brings substantial background IP and the key skills required. The research responds to the needs of industry partners and involves substantive international collaboration as well as a wider international and UK network across the REE value chain. The work programme has two strands. The first centres on conventional deposits, which comprise all of the REE mines outside China and the majority of active exploration and development projects. The aim is to make a step change in the understanding of the mobility of REE in these natural deposits via mineralogical analysis, experiments and computational simulation. Then, based on this research, the aim is to optimise the most relevant extraction methods. The second strand looks to the future to develop a sustainable new method of REE extraction. The focus will be the ion adsorption deposits, which could be exploited with the lowest environmental impact of any of the main ore types using a well-controlled in-situ leaching operation.Impact will be immediate through our industry partners engaged in REE exploration and development projects, who will gain improved deposit models and better and more efficient, and therefore more environmentally friendly, extraction techniques. There will be wider benefits for researchers in other international teams and companies as we publish our results. Security of REE supply is a major international issue and the challenges tackled in this research will be relevant to practically all REE deposits. Despite the UK not having world class REE deposits itself, the economy is reliant on REE (e.g. the functional materials and devices industry is worth ~£3 Bn p.a.) and therefore the UK must lead research into the extraction process. Manufacturers who use REE will also benefit from the research by receiving up to date information on prospects for future Nd and HREE supply. This will help plan their longer term product development, as well as shorter term purchasing strategy. Likewise, the results will be useful to inform national and European level policy and to interest, entertain and educate the wider community about the natural characters and importance of the REE.

稀土元素（REE）是供应议程关键金属安全的标题。所有REE在2010年被欧盟定义为至关重要的，在随后的2014年分析中。英国和美国的类似项目强调了“重型” REE（Hree -Europium- Europium to Lutetium），因为金属最有可能面临供应中断的风险，并且在不久的将来都有供应中断和短期供应。 REE在现代技术中无处不在，包括计算机和低能照明，能源存储设备，大型风力涡轮机和智能材料，使其对英国社会至关重要。面临的挑战是要开发新的环境友好且在经济上可行，新近山（ND）和Hree存款，以便在新的和绿色的技术中使用REE可以继续扩展。该项目的主要目的是了解自然系统中ND和HERE的迁移率和集中度，并降低了REE的恢复环境和研究的新过程。考虑了技术。它为NERC和英国提供了有关关键REE的世界领先的研究联盟，专注于在催化剂阶段确定的存款类型，最有可能对环境产生较低的影响，以及桥接SOS计划的两个目标的研究。该项目汇集了两个群体，将两组汇集在一起​​，从催化剂项目（包括Gem-cre，MM-Free the Inukery the Interdiry Interderirily Geleders）中，将两组汇集在一起​​，以融为一体，将其组合起来，以融合了新的互联网，并将其融合在一起。材料科学，高/低温流体地球化学，计算模拟/矿物质物理学，地球生物学和生物处理。团队带来了大量的背景知识产权和所需的关键技能。该研究响应了行业合作伙伴的需求，并在REE价值链中涉及实质性的国际合作以及广泛的国际和英国网络。该工作计划有两个链。最初的关于常规存款的中心，该存款构成了中国以外的所有REE地雷以及大多数积极的勘探和开发项目。目的是通过Mineraological Analysis，实验和计算模拟对REE在这些自然沉积中的迁移率的理解进行逐步改变。然后，基于这项研究，目的是优化最相关的提取方法。第二条链希望未来开发一种可持续的REE提取方法。重点将是离子添加吸附沉积物，可以使用良好控制的原位利用操作对任何主要矿石类型的环境影响进行探索。影响力将通过我们从事REE勘探和开发项目的行业合作伙伴立即进行，他们将获得改进的存款模型，并获得更高的储备模型，更有效，更有效，因此具有更高的环境友好的技术。当我们发布结果时，其他国际团队和公司的研究人员将为研究人员带来广泛的好处。 REE供应的安全是一个主要的国际问题，这项研究所面临的挑战将与几乎所有REE存款有关。尽管英国没有世界一流的REE存款本身，但经济与REE相关（例如，功能材料和设备行业的价值约为30亿英镑），因此英国必须领导对提取过程的研究。使用REE的制造商还将通过收到有关未来ND和Hree供应的前景信息的最新信息，从研究中受益。这将有助于计划其长期产品开发以及较短的定期购买策略。同样，结果将对信息国家和欧洲一级的政策以及对REE的自然特征和重要性的兴趣，娱乐和教育。
