随着黄金工业的发展，高品位、易选金矿石逐年减少，而低品位、难选金矿石比重加大，这类金矿石，由于微细的金颗粒被黄铁矿、毒砂紧密包裹，传统的氰化工艺很难奏效。细菌预氧化——氰化提金法是一种处理这类难选矿石的有效工艺，成本低、操作简单、不污染环境。采用人工培育
With the development of the gold industry, high-grade, easy-to-choose gold ore decreases year by year, while the proportion of low-grade and refractory gold ore increases. Due to the fine gold particles being closely packed with pyrite and arsenopyrite, the traditional Cyanide process is difficult to work. Bacterial pre-oxidation - cyanidation gold method is an effective treatment of such refractory ore technology, low cost, simple operation, does not pollute the environment. Using artificial cultivation
