项目摘要

Nickeliferous pyrrhotite tailing is a waste stream from the processing of nickel sulfide ores for nickel production. An estimated amount of 50~100 million tonnes of the material has been deposited in shallow lakes or dams in the Sudbury district, Ontario, which poses a potential environmental hazard for the local environment. The proposed project aims at developing a process to recover all values (Ni, Fe and S) from this stream, thereby convert the waste to value, and address the environmental concern at the same time. The final products from the process are Fe-Ni alloys, Fe powders, elemental sulfur for various industrial applications, as well as electricity. The various steps of the process are integrated in a way that would produce products of high economic value with minimal environmental impact and energy consumption, making it attractive from all technical, environmental, and economic perspectives.The proposed three-year project will involve approximately 15 researchers. Thus a large number of highly qualified personnel will be trained through the research. A great deal of knowledge will also be gained by testing the innovative ideas put forward and collaboration with the industry, leading to substantial development of this technology as well as its potential commercialization. By directly addressing the sustainability issues of the mining and metallurgical sectors, this proposed process could bring about benefits to Canada from the economic, social and environmental aspects.

镍黄铁矿尾巴是从镍矿石加工镍生产的废物流。估计有50 〜1亿吨材料存放在安大略省萨德伯里区的浅湖或大坝中，该材料对当地环境造成了潜在的环境危害。拟议的项目旨在开发一个从此流中恢复所有值（NI，FE和S）的过程，从而将废物转换为价值，并同时解决环境问题。该工艺的最终产品是Fe-Ni合金，Fe粉，用于各种工业应用的元素硫以及电力。该过程的各个步骤的整合方式将产生高经济价值的产物，而环境影响和能源消耗最小，从而使其从所有技术，环境和经济角度来吸引它。拟议的三年项目将涉及大约15名研究人员。因此，通过研究将对大量高素质的人员进行培训。通过测试与行业提出的创新想法并协作，还可以获得大量知识，从而实质性地发展了这项技术及其潜在的商业化。通过直接解决采矿和冶金领域的可持续性问题，这一提议的过程可以从经济，社会和环境方面为加拿大带来好处。
