氰化钠是铅锌选矿中对铅锌分离的一种有效的抑制剂,习用已久;但它是一种有剧毒的物质,又价格昂贵,来源不易,特别是含氰尾矿水污染江河,对农业、渔业及人民身体健康危害甚大,并且氰化物有溶解金的特性,给矿石中的贵金属造成损失。近年来国内有关矿山,为了改变这一状况,已在采用无氰选矿工艺,并获得良好效果。桃林铅锌矿选厂为了推广这一先进工艺,在矿党
Sodium cyanide is a potent inhibitor of the separation of lead and zinc from lead-zinc concentrates, and has long been used conventionally; however, it is a highly toxic substance that is expensive and not readily available Rivers, on agriculture, fisheries and the health of people is very harmful, and cyanide has the characteristics of dissolved gold, to the loss of precious metals in the ore. In recent years, the relevant domestic mines, in order to change this situation, has been using non-cyanide beneficiation process and achieved good results. Taolin lead-zinc ore processing plant in order to promote this advanced technology in the mining party
