Mining activities are one significant source of anthropogenic sulfate into natural waters, mainly due to the extraction of metals from ubiquitous sulfur containing ores such as, pyrite and pyrrhotite. Because of its detrimental impact to freshwater species especially at high concentrations, its removal remains a priority in mine effluents. Future trends in regulatory practice may promote more research and application of sulfate removal technologies through desalination of mine water effluent. There are several strategies for mitigating sulfate removal. Among current options, ion exchange is very common. In this context, Aldex chemicals has developed a resin for sulphate removal in industrial water. Investigating other markets including mine sector is very challenging for the company. For this attempt, they tend to collaborate with the CTRI to demonstrate and validate the efficiency of their ion exchange technology for sulphate removal in mine effluents especially in cold climate. 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.

采矿活动是人为硫酸盐进入天然沃茨的一个重要来源，主要是由于从普遍存在的含硫矿石（如黄铁矿和磁黄铁矿）中提取金属。由于其对淡水物种的有害影响，特别是在高浓度时，其去除仍然是矿山废水中的优先事项。监管实践的未来趋势可能会促进更多的研究和应用硫酸盐去除技术，通过淡化矿井水废水。存在用于减轻硫酸盐去除的若干策略。在目前的选择中，离子交换非常常见。在这种情况下，Aldex化学公司开发了一种用于去除工业用水中硫酸盐的树脂。调查包括采矿业在内的其他市场对公司来说非常具有挑战性。为此，他们倾向于与CTRI合作，以证明和验证其离子交换技术在矿山废水中去除硫酸盐的效率，特别是在寒冷气候下。该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;在给定的期限内实现项目目标的基本要素。
