This is a fundamental study on the use of resin and polymer-based ligands to recover copper and cyanide from gold cyanidation tailings. This process is environmentally more acceptable than other recovery methods, as it does not involve the use or generation of harmful species, such as HCN. It also has the advantage that copper metal and cyanide are recovered as products from the copper cyanide containing streams. Thus the proposed project has the potential to substantially alter the gold recovery process, particularly in an era where environmental and public concerns exist over the discharge of cyanide species into tailings dams.

这是利用树脂和聚合物配体从金氰化尾矿中回收铜和氰化物的基础性研究。这一过程在环境上比其他回收方法更容易接受，因为它不涉及使用或产生有害物种，如六氯甲烷。它还具有从含铜氰化物的溪流中回收铜金属和氰化物作为产品的优点。因此，拟议的项目有可能极大地改变黄金回收过程，特别是在环境和公众对向尾矿坝排放氰化物物种存在关切的时代。
