摘　　要：随着人们对黄金等贵金属的需求不断增大,金矿企业获得了前所未有的发展。但是,随着金矿开采的进行,易处理金矿资源日渐枯竭,所以我们只能把目光投向难处理的低品位金矿。难处理金矿要用传统的氰化浸金方法来提取金,就必须要用一定的方法进行预处理。生物氧化法由于自身的环境友好性,以及不产生有毒有害物质等优点而不断被现代金矿企业所采用。我们通过对生物氧化预处理低品位金矿的机理分析、影响因素、国内外研究发展现状、前景展望等方面,简要介绍生物氧化法预处理低品位金矿的优越性。In recent years, with the development of economy, people’s living is improving, and people’s demandfor precious metals such as gold is increasing. But, with gold mining, easy processing gold resources is graduallyreduced, so we can only turn to intractable low grade gold mine. If we want to use the traditional method of cya-nide leaching of gold extract gold from low grade gold mine, we will have to be pre-treated in a certain way. Bio-logical oxidation process has been adopted by modern gold miners because of its environmental friendliness, anddoes not produce toxic or harmful substances, etc. In this paper we introduced the superiority of this method topre-treat low grade gold mine based on the mechanism analysis, influence factors, domestic and foreign researchdevelopment status,outlook, etc.
