This proposal describes the plan for the development of transformative processes for production of pure feed for the battery and magnet industry. The focus is put on impurity removal from nickel (Ni) and cobalt (Co) precursor for cathode production of lithium-ion batteries as well as solvometallurgical reduction of rare earth element (REE) compounds for magnet production. The proposed project will enable near-term objective of providing high quality feed materials to the Canadian energy and metal industries, as well as long-term objectives of delivering significant environmental benefits by using more efficient and environmentally friendly processes. The conventional process for impurity removal from Ni and Co feed relies on solvent extraction which requires large volumes of organic solvents, large number of stages with high operating cost and generates large volumes of waste. The conventional process for REE reduction relies on molten salt electrolysis that is energy intensive and takes place in a corrosive environment involving fluorides or chlorides, generates environmental pollutions due to chlorine or fluorine gases and requires high operating cost. The proposed processes in this project are based on complexation and selective precipitation for impurity removal and solvometallurgy using sodium in liquid ammonia and alkalides and electrides for REE reduction. These processes are novel and require a fresh methodological approach and close academic-industry partnership. Preliminary results have established proof-of-principle for these processes. This project leverages expertise and funds from Hatch, a knowledge-based pioneer consulting firm and technology and in-plant service provider to the global metals, infrastructure, and energy sectors, in a four-year partnership with the Azimi group at the University of Toronto. This project is highly beneficial for Canada in terms of academic excellence, industrial competitive advantage, and highly qualified personnel, as it creates the opportunity for knowledge based economic and environmental impact as well as enhanced technical edge in the Canadian Minerals, Metals, and Energy sectors.

该提案描述了开发用于电池和磁铁行业纯饲料的变革过程的计划。将重点放在从镍（Ni）和钴（CO）前体中去除液化电池的阴极产生的杂质，以及用于磁铁生产的稀土元素（REE）化合物的溶剂化铝还原（REE）化合物。拟议的项目将使近期目标能够为加拿大能源和金属行业提供高质量的饲料材料，以及通过使用更高效和环保的过程来提供重大环境益处的长期目标。从NI和CO Feed中去除杂质的常规过程依赖于溶剂提取，该提取需要大量有机溶剂，大量的阶段，其工作成本高，并产生大量的废物。 REE减少的常规过程取决于能量密集型的熔融盐电解，并发生在涉及氟化物或氯化物的腐蚀性环境中，由于氯或氟气体而产生环境污染，需要高运营成本。该项目中提出的过程基于使用液体氨，碱和电气的综合性去除和溶剂化铝的选择性降水，以减少REE。这些过程是新颖的，需要一种新的方法论方法和紧密的学术行业伙伴关系。初步结果已经为这些过程确定了原则证明。该项目将基于知识的先驱咨询公司和技术以及在全球金属，基础设施和能源领域的植物内部服务提供商Hatch的专业知识和资金与多伦多大学的Azimi集团进行了四年合作。就学术卓越，工业竞争优势和高素质的人员而言，该项目对加拿大非常有利，因为它为基于知识的经济和环境影响创造了机会，并增强了加拿大矿物质，金属和能源部门的技术优势。
