Gold Extraction via High Temperature Chlorination

金属和矿产工业严重依赖水，水是人类日常生活中最宝贵的资源之一。在黄金加工厂中，水被广泛用于通常用氰化物浸出处理低品位矿石的地方。该工艺的浆状尾矿储存在尾矿池**中，其中储存的水占采矿过程中最大的不可用水。**Goldcorp推出了一项雄心勃勃的节水战略，其最终目标是引领金属和矿产行业大幅减少用水量，并最终消除传统矿浆尾矿的使用。**目前的提案旨在研究通过氯化物挥发回收黄金的方法，最终目标是开发出具有更低用水量的提取黄金的替代工艺。将在不同的操作参数下考察挥发过程的效率。该项目的成果将为减少黄金提取过程中的用水量提供一条途径。该工艺特别适用于水资源匮乏的地区，可以显著减少与黄金提取相关的水污染。

The metals and minerals industries are heavily dependent on water, one of the most precious resource for**day-to-day life of human being. In gold processing plants water is extensively used where low grade ores are**customarily treated with cyanide leaching. The slurry tailings of the process are stockpiled in tailing ponds**where the stored water accounts for the largest unavailable water in the mining process.**Goldcorp has launched an aspiring water reduction strategy with the ultimate goal of leading the metals and**mineral industries in exceedingly reducing water consumption and eventually eliminating the use of traditional**slurry tailings.**With the final goal of developing alternative processes for extracting gold with lower water consumption, the**current proposal investigates gold recovery via chloride volatization. The efficiency of the volatilization**process will be examined under various operating parameters. The outcome of this project will provide a path**towards reducing the water consumption in gold extraction process. The process is specifically favorable for**regions with water scarcity and can significantly reduce the water pollution associated with gold extraction.
