本文简要回顾了世界主要产金国澳大利亚的金矿产品的性质和湿法冶金工艺；讨论了对易选、复杂和难选矿石采用不同方法分选的依据．氰化－氰化和炭浆法或炭浸法是处理易选矿石最基本的也是最成熟的方法；还论述了和炭浆法有关的含铜矿石的分选．论述了耗氧型和内质竞争型矿石的分选；详细介绍了难选矿石预处理的5种方法：超细磨、酸浸或碱浸热压氧化、活化法、HMC法和电解氧化法．在澳大利亚，焙烧和生物氧化是预处理难选金矿石的常用方法，在这方面的进展情况也常有报道．介绍了澳大利亚戈登斯佩克（GoldenSpec）矿采用加压氰化法富集辉锑矿的尝试；而到目前为止，热解法、硝化／氧化法、Artech／Cashman法以及卡氏酸法还没有真正用于工业实践。讨论了矿浆离子交换树脂法替代炭浆法选金的发展潜势．由于氰化物具有毒性而带来环保问题，因此就要研究其他能使用无毒药剂的提金方法．氰化的主要替代品有：氨的硫代硫酸盐、硫脲和卤化物溶液．简要论述这些浸滤方法的化学机理，并对流程加以说明，还预测了生物湿法冶金的远景．
This article briefly reviews the properties of gold ore products and hydrometallurgical processes in Australia, the main gold producing country in the world. The basis for the selection of alternative, complex and refractory ore by different methods is discussed. Cyanide-cyanidation and carbonization or carbon-leaching are the most basic and mature methods for the treatment of readily-available ores. The classification of copper-bearing ore related to the carbonization process is also discussed. Discusses the selection of oxygen-consuming and endoplasmic competing ores. Five kinds of pretreatment methods for refractory ore are introduced in detail: ultrafine grinding, hot-pressing and acid-leaching or alkali-impregnation oxidation, HMC and electrolytic oxidation . In Australia, roasting and biooxidation are common methods for pretreatment of refractory gold ore and progress has also been reported in this area. Attempts have been made to enrich the stibnite by the pressurized cyanidation at the GoldSpec mine in Australia. Until now, pyrolysis, nitration / oxidation, Artech / Cashman, Not really used in industrial practice. The development potential of pulp ion exchange resin method instead of carbon slurry method was discussed. Due to the toxicity of cyanide and bring environmental problems, it is necessary to study other non-toxic drugs can be used gold extraction method. The main alternatives to cyanation are: ammonia thiosulfate, thiourea and halide solutions. A brief discussion of the chemical mechanisms of these leaching methods, along with a description of the process, also predicts the future of biohydrometallurgy.
