Investigation and Testing of Environment-friendly and Energy-efficient Freezing Technology for the Remediation of Mine-impacted household water

该提案是与怀特霍斯的Core Geoscience Services Inc. （Coregeo）合作的，涉及的技术将对全球极地地区和温带地区有益且经济可行。考虑到五个最大的联邦污染地点中的三个——法鲁矿、巨人矿、科洛马克矿——位于育空地区和西北地区，加拿大北部是特别值得关注的，在这些地区，新矿区通常需要进行水处理。伙伴关系的主要目标是基于不同的观点：(a)以具有成本效益的方式协助杂质分离过程，并有可能减少政府修复受污染矿区的费用；(b)克服在水的冷冻净化以作回用方面的知识差距，发展创新的水处理技术；(c)通过向其他司法管辖区推广和出口这项技术，为加拿大的长期竞争力做出贡献。

The proposal in partnership with Core Geoscience Services Inc. (Coregeo), Whitehorse, YT, deals with technology that will be beneficial and economically feasible for the polar regions and more temperate locations worldwide. Northern Canada is of special interest considering that three of the five largest federal contaminated sites - Faro Mine, Giant Mine, Colomac Mine - are located within Yukon and Northwest Territories where a water treatment is normally required for new mine sites. The main goals of partnership are based on diverse perspectives: (a) to assist in the process of impurity separation in a cost-effective manner, with the potential to reduce government costs for remediation of contaminated mine sites; (b) to overcome knowledge gaps in the field of cryopurification of water for water reuse to develop an innovative water treatment technology; and (c) to contribute to Canada's long-term competitiveness by promoting and exporting this technology potentially to other jurisdictions as well. The outcomes of the project are planned to form a foundation for the development of an exceptional, energy efficient water treatment technology that utilizes northern climates' cold temperature conditions and has the potential to be scaled up and applied at the Faro site or other mine sites, or industrial sites. The removal of contaminants using cryopurification techniques such as freeze concentration, spray freezing and frazil ice formation, is one of the innovative water treatment concepts. It was reported based on laboratory and field data that freezing technology can be effective for the removal of both inorganic and organic contaminants from aqueous solution. However, a comprehensive investigation of zinc removal from mine-contaminated water using cryopurification technology has not been reported in the literature. Coregeo has fulfilled the preliminary tests/study on zinc removal from mine-impacted water using a range of cryopurification techniques. This led to the current partnership to deeper investigate and test the cutting-edge cryopurification technology.
