摘要
金精矿氰化渣经铅浮选后 ,尾矿再进一步综合回收铅、锌、金、银、硫 ,在资源不足的情况下 ,为矿山开辟了一条新的途径。试验中 ,采用Na2 SiF6、纤维素联合强化抑制剂 ,重点抑制脉石矿物和黄铁矿 ,加入CuSO4 活化剂活化强烈抑制的锌矿物 ,使铅、锌混合精矿达到了产品质量要求 。
After the lead flotation of cyanidation slag of gold concentrate, the lead, zinc,gold,silver and sulphur are comprehensively recovered furtherly from lead flotation slag,which creats a way to mine under the shortage of resources.Using combined depressants of Na 2SiF 6 and cellulose to depress gangue minerals and pyrite,and using CuSO 4 to activate zinc minerals that have been depressed strongly,by which the mixed concentrate quanlity of lead and zinc meet the demands of production quanlity,and good technical indexes are obtained.
