从矿石中回收共生铅银要达到较高的分选指标,需采用不同的药剂制度,通常浮铅的调整剂(石灰、硫化钠、氰化物)将使银矿物的可浮性变坏,从而提出了选用具有选择作用的药剂问题。在中亚细亚某一铅银矿选矿厂处理的矿石性质是:氧化铅的含量极不稳定(15％到85％);铅银回收率的相关系数比较小(r=0.53)。主要的工业有价铅矿物是方铅矿、白铅矿、铅矾和少量铅铁矾(6％),银的赋存状态是,在方铅矿中以银黝铜矿和针铅鉍 Recovery of symbiotic lead and silver from ore to achieve a higher sorting index, the need for a different pharmaceutical system, usually float lead regulator (lime, sodium sulfide, cyanide) will make the flotability of silver minerals to deteriorate, and thus Proposed selection of the role of the choice of pharmaceutical problems. The nature of the ores treated at a lead-silver concentrator in Central Asia is that the lead oxide content is extremely unstable (15% to 85%); the correlation coefficient for lead-silver recovery is relatively small (r = 0.53). The main industrial-value lead minerals are galena, lead, lead and a small amount of lead alum (6%). The silver deposit is characterized by the presence of silver-tetrahedrite and lead-bismuth
