Sustainable processing of Canadian sulphides

加拿大是世界上最重要的矿业国家之一，生产60多种矿物和金属。采矿和矿物加工长期以来一直是该国主要的财富来源之一。2014年，该行业雇佣了约37.5万人，为加拿大的国内生产总值（GDP）贡献了570亿美元。这种矿物财富的主要来源之一是贱金属硫化物，这仍然需要大量工作来改进有价值矿物的可持续提取和分离。

Canada is one of the most important mining nations in the world, producing more than 60 minerals and metals. Mining and mineral processing has long been one of the country's key wealth generators. In 2014, the sector employed approximately 375,000 people and contributed $57 billion to Canada's Gross Domestic Product (GDP). One of the major sources of this mineral wealth is in base metal sulphides, which still require significant work to improve the sustainable extraction and separation of valuable minerals. This research proposal aims at generating new knowledge related to sulphide mineral processing, including the reagents used, environmental considerations, and the separation processes employed. Although the proposal is centred on sulphide deposits and operated by the industrial sponsors, the results will be applicable across several mineral deposits, not just those under investigation. The overall goals of this proposal are: 1) to train HQPs in mineral processing, an area vital to Canada's economy; 2) to conduct fundamental and multi-disciplinary research in mineral processing; 3) to meet the short to medium term research needs of the sponsors; and 4) to provide continuing education opportunities for sponsor personnel. The research covers environmental aspects, flotation, physical separations and mineralogy studies, which all link together to promote sustainable processing of Canada's sulphide deposits. This CRD project will provide the Canadian economy with 21 HQP that will be highly trained and ready to join the minerals industry. The skills HQP will acquire will make them competitive for a wide range of careers, including government (e.g. public policy and environment), industry or as entrepreneurs in their own companies. The mining industry as a whole will benefit from these developments to improve safety and to reduce the harmful impacts of mining on the environment.
