水口山铅锌矿选矿副产的硫铁矿精矿,一部分销售于松柏化肥厂和水口山一厂。我们先后对上述两个单位产出的硫铁矿烧渣进行了浮选金银的小型试验。在试验条件基本相同的情况下,获得的选别指标很悬殊,说明同一硫铁矿进入两个沸腾焙烧炉中,所产出的硫铁矿烧渣中的金银具有不同的可浮 Some of the pyrite concentrates by-product of Shuikoushan lead-zinc ore beneficiation are sold in part by the Songbai Fertilizer Plant and Shuikoushan Plant. We have conducted a pilot study of flotation of gold and silver on pyrite cinders produced by the above two units. In the case of the same test conditions, the obtained sorting index is very poor, indicating that the same pyrite into the two roasting roaster, the output of pyrite cinder gold and silver have different floating
