Study of Thiocyanate Removal from Mine Water Using Ion Exchange Combined with Electro-Oxidation

硫氰酸盐是一种潜在的令人担忧的污染物。硫氰酸盐存在于许多工业流程和受影响的水中，如贵金属开采和回收、煤炭炼焦、缓蚀和电镀行业。尽管硫氰酸盐的毒性比氰化物小，但它对接收环境的影响可能是巨大的。在目前的选择中，离子交换与电氧化相结合是非常有创新性的。在此背景下，BQE开发了这一创新的硫氰酸盐去除集成技术。在寒冷的温度下用真正的矿泉水展示技术的效率和性能是BQE的主要关注点，再次调查Abitibi的其他市场也是具有挑战性的。在这一尝试中，他们倾向于与CTRI合作，展示和验证他们的离子交换技术结合电氧化去除矿山废水中硫氰酸盐的效率，特别是在Abitibi寒冷的气候条件下。这个项目将受益于一个多学科的团队和一个可操作的研发基础设施；这是在给定的最后期限内实现项目目标的基本要素。

Thiocyanate as a Contaminant of Potential Concern. Thiocyanate is found in a number of industrial process streams and impacted waters such as precious metals mining and recovery, coal coking, corrosion inhibition, and electroplating industries. Although thiocyanate is less toxic than cyanide, its impact on the receiving environment can be significant. Among current options, ion exchange combined with electrooxidation is very innovative. In this context, BQE has developed this innovative integrated technology for thiocyanate removal. Demonstrating the efficiency and the performance of technology with a real mine water at cold temperatures is a main concern for the BQE and again investigating other markets in Abitibi is also challenging. For this attempt, they tend to collaborate with the CTRI to demonstrate and validate the efficiency of their ion exchange technology combined with electrooxidation for thiocyanate removal in mine effluents especially in cold climate of Abitibi. This project will benefit from a multidisciplinary team and an operational R&D infrastructure; essential ingredients for achieving the project's objectives within the given deadlines.
