对于深度氧化,不含硫化物或含少量硫化物,而含有大量泥质组分(如绢云母等)的含金氧化矿石,采用浮选法选矿,选矿指标一般都比较低。目前国内外选别这种矿石主要采用氰化法。采用氰化法工艺比较合理,可取得较高的技术经济指标。但是,由于氰化物污染环境,需要对尾渣、尾水采取必要的技术措施进行处理,使其氰化物含量低于国家要求的排放标准。对污渣、污水的处理势必造成选矿工
For the deep oxidation, sulfide-free or containing a small amount of sulfide, and contains a large number of argillaceous components (such as sericite, etc.) of gold-bearing ore, flotation beneficiation, beneficiation indicators are generally lower. At present, the main selection of this ore at home and abroad cyanidation. Cyanide process more reasonable, high technical and economic indicators can be obtained. However, due to cyanide pollution of the environment, the tailings, tail water need to take the necessary technical measures to deal with its cyanide content below the national emission standards. On the sludge, sewage treatment is bound to result in miners
