毒砂和黄铁矿是广泛存在的赋金矿物,我国这两种含金矿物资源十分丰富.金通常以显微金或次显微金的形式被包括在这两种矿物中,因此,在用湿法冶金的方法从含金硫化矿提金过程中,毒砂和黄铁矿的分解程度对金的提取率有决定性的影响.然而,毒砂和黄铁矿是很难用湿法分解的顽固矿物,从中提金的传统方法是焙烧——氰化法.由于环境保护日趋严格,焙烧过程带来的As_2O和SO_2污染已引起广泛的关注.因此,近 Arsenopyrite and pyrite are widely exchanging gold-bearing minerals, and the two gold-bearing minerals in our country are very abundant. Gold is usually included in both minerals in the form of micro-gold or sub-micro-gold. Therefore, With the hydrometallurgical method, the degree of decomposition of arsenopyrite and pyrite has a decisive effect on the extraction rate of gold from gold-bearing sulphide ore, however, arsenopyrite and pyrite are difficult to decompose with wet methods The traditional method of extracting gold from it is roasting-cyanidation method.As the environmental protection is becoming more and more strict, the pollution of As 2 O and SO 2 caused by the roasting process has drawn wide attention.Therefore,
