The presence of copper is a major problem in Australia's gold industry. We have proposed an innovative method for treating copper containing ores which eliminates discharge of copper and cyanide to the tailings dam. The copper is recovered, and the cyanide is either recycled or destroyed within the plant. Another advantage of the process is a reduction in the cyanide requirement, hence reducing the risk associated with cyanide transport and storage. Thus the proposed project has the potential to substantially improve the gold recovery process, particularly in an era where environmental and public concerns exist over the use of cyanide.

铜的存在是澳大利亚黄金行业的一个主要问题。我们提出了一种处理含铜矿石的创新方法，该方法消除了铜和氰化物向尾矿坝的排放。铜被回收，氰化物被回收或在工厂内销毁。该方法的另一个优点是减少了氰化物的需求，从而降低了与氰化物运输和储存有关的风险。因此，拟议的项目有可能大大改善黄金回收过程，特别是在一个环境和公众对氰化物使用存在担忧的时代。
