This proposal describes the plan for the development of breakthrough technologies for the extraction of iron from ore, refinement of the final steel product, and valorization of the slag byproduct. Primary steel, with the annual demand of 1.6 billion tons, is produced by carbothermic reduction in blast furnace, emitting million tons of CO2 (about 4-7% of the total anthropogenic GHG emissions emanate from steelmaking). Environmental concerns led industries worldwide to search for environmentally sound technologies, and to this end, the steel industry is exploring the feasibility of using electrochemical technologies that can potentially be carbon free.This project aims to transform steelmaking into an environmentally friendly and sustainable industry. The work plan involves three concurrent Segments focusing on: (I) Developing and advancing high temperature electrolysis for iron extraction, (II) Developing an innovative electrorefining process for producing high purity steel, and (III) Developing a novel process for the valorization and inertization of steel slag. Preliminary results have established proof-of-principle for these processes. To achieve the goals of the project, a multidisciplinary approach that places at the intersection of materials science and engineering, molten salt electrochemistry and thermodynamics, hydrometallurgy, materials characterization, and process engineering and optimization will be followed.This project leverages expertise, facilities, and funds from Tenova Goodfellow, a knowledge based, pioneering technology-providing company offering cutting edge know-how to a wide range of industries, in particular steelmaking, in a 4-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 steelmaking industry.

该提案描述了从矿石中提取铁、精炼最终钢铁产品以及矿渣副产品的增值等突破性技术的开发计划。年需求量16亿吨的初级钢是通过高炉碳热还原生产的，排放数百万吨二氧化碳（约占炼钢过程中人为温室气体排放总量的4-7%）。环境问题促使全球各行业寻求环保技术，为此，钢铁行业正在探索使用可能无碳的电化学技术的可行性。该项目旨在将炼钢转变为环保和可持续发展的行业。该工作计划涉及三个同时进行的部分，重点是：(I) 开发和推进高温电解提铁，(II) 开发生产高纯钢的创新电解精炼工艺，以及 (III) 开发钢渣增值和惰化的新型工艺。初步结果已经为这些过程建立了原理验证。为了实现该项目的目标，将采用材料科学与工程、熔盐电化学和热力学、湿法冶金、材料表征以及工艺工程和优化交叉的多学科方法。该项目利用了Tenova Goodfellow的专业知识、设施和资金，Tenova Goodfellow是一家以知识为基础的开拓性技术提供公司，为各行各业提供尖端专业知识，特别是 与多伦多大学 Azimi 集团合作为期 4 年的炼钢业务。该项目在学术卓越、行业竞争优势和高素质人才方面对加拿大非常有利，因为它为基于知识的经济和环境影响以及增强炼钢行业的技术优势创造了机会。
