Australia is one of the world's largest producers of gold, and the ability to more efficiently separate gold from its ores will benefit the Australian economy by maximising the value of every tonne of ore which is removed from the ground. Inefficiencies in processing technology can lead to the loss of gold from extraction processes, and the reasons for some of these losses are poorly understood but are believed to be related to interactions between gold and silicate minerals. We will study these interactions with a view towards improving the percentage of gold present in the ores which is able to be extracted and used.

澳大利亚是世界上最大的黄金生产国之一，更有效地将黄金从矿石中分离出来的能力将使从地下开采出来的每吨矿石的价值最大化，从而使澳大利亚经济受益。加工技术效率低下可能导致提取过程中金的损失，其中一些损失的原因尚不清楚，但据信与金和硅酸盐矿物之间的相互作用有关。我们将研究这些相互作用，以期提高矿石中能够提取和利用的金的百分比。
