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.

硫氰酸盐作为潜在关注的污染物。硫氰酸盐存在于许多工业流程流和影响水域中，如贵金属开采和回收、煤炭炼焦、缓蚀和电镀工业。虽然硫氰酸盐的毒性比氰化物小，但它对接收环境的影响可能很大。在目前的选择中，离子交换与电氧化相结合是非常具有创新性的。在此背景下，BQE开发了这种创新的硫氰酸盐去除集成技术。BQE主要关注的是在低温下用真实的矿井水展示技术的效率和性能，而在阿比提比调查其他市场也具有挑战性。对于这一尝试，他们倾向于与CTRI合作，以证明和验证他们的离子交换技术结合电氧化去除矿井废水中硫氰酸盐的效率，特别是在阿比提比寒冷气候下。该项目将受益于多学科团队和可操作的研发基础设施；在规定期限内实现项目目标的基本要素。
