摘　　要：介绍了难选冶金矿石预处理现状,对氧化焙烧、加压氧化法、常压氧化法、细菌氧化法、硝酸催化氧化法、微波焙烧法以及其它预处理方法进行了分析比较。提出应从投资低、生产成本低、污染少、易于分散建厂、效益好等来考虑,选择最佳的处理方案。The status quo of pretreatment technique of refractory gold ores is introduced. The pretreatmert ways of these resources such as oxidation roast, pressure oxidation, non-pressure oxidation, bacteria oxidation, nitric acid catalyzing oxidation, microwave roast and other pretreatment ways are analyzed and compared. It considers that it should select the optimum treating plan on the basis of less investment, low production costs, less pollution, easy construction of plant and good benefits.
