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.

该提案与核心地球科学服务公司合作。（Coregeo），Whitehorse，YT，涉及对极地地区和世界上更温和的地区有益且经济上可行的技术。考虑到五个最大的联邦污染场地中的三个- Faro矿、Giant矿、Colomac矿-位于育空地区和西北地区，因此加拿大北方具有特殊的意义，在这些地区，新的矿址通常需要进行水处理。伙伴关系的主要目标基于各种不同的观点：（a）以具有成本效益的方式协助杂质分离过程，并有可能减少政府对受污染矿址的补救费用;（B）克服水的低温净化领域的知识差距，以开发创新的水处理技术，从而实现水的再利用;以及（c）通过推广和向其他司法管辖区出口这一技术，为加拿大的长期竞争力做出贡献。 该项目的成果计划为开发一种特殊的节能水处理技术奠定基础，该技术利用北方寒冷的气候条件，并有可能在Faro现场或其他矿场或工业现场扩大规模和应用。使用冷冻浓缩、喷雾冷冻和冰花冰形成等低温净化技术去除污染物是创新的水处理概念之一。根据实验室和现场数据，冷冻技术可以有效地去除水溶液中的无机和有机污染物。然而，利用低温净化技术从矿山污染水中去除锌的全面调查还没有在文献中报道。Coregeo已经完成了使用一系列低温净化技术从受矿山影响的水中去除锌的初步测试/研究。这导致了目前的合作伙伴关系，以更深入地研究和测试尖端的冷冻纯化技术。
