The recovery of gold at Stawell Gold Mine can be improved by using cyanide and thiocyanate free water in the milling process. The aim of this research is the development of a novel separation technology for the removal of these two ions from mine wastewater to allow it to be recycled. Novel polymeric materials, known as polymer inclusion membranes (PIMs), which have never been used before in industrial separation, will be at the centre of this technology. In addition to increasing gold recovery, this technology is expected to reduce substantially the reliance of the Australian goldmining industry on fresh water. This research will also promote PIM based separation as a viable industrial separation technology, applicable in other areas.

在选矿过程中采用氰化物和硫氰酸盐游离水可以提高斯塔维尔金矿金的回收率。本研究的目的是开发一种新的分离技术，从矿山废水中去除这两种离子，使其能够循环利用。新型聚合物材料，被称为聚合物包合膜（pim），以前从未在工业分离中使用过，将成为这项技术的核心。除了提高黄金的回收率外，这项技术预计将大大减少澳大利亚金矿采矿业对淡水的依赖。这项研究也将促进基于PIM的分离作为一种可行的工业分离技术，适用于其他领域。
