摘要
以“矿浆电解法”为基础 ,结合广西难处理复杂锑铅矿的铅锑分离难题 ,用矿浆电解法对复杂锑铅矿的处理进行了研究。研究证实 ,采用矿浆电解法处理复杂锑铅矿 ,可以实现锑、铅的一步分离和锑的一步提取 ,在阴极可以直接得到金属梯板 ,锑的浸出率大于 98%。铅以PbCl2 的形态沉淀入渣 ,经碳铵转化 -脱硫 ,可以得到含铅大于 45 %、含硫小于 15 %的铅精矿和单质硫产品 ,铅的总回收率大于95 % ,银的总回收率大于 80 %。
Based on Slurry Electrolysis Process,and combined with the problem of separation of antimony from lead for refractory antimony lead concentrate in Guangxi,China, a series of tests have been done Using Slurry Electrolysis Process to treat complex antimony lead concentrate,antimony can be separated from lead in one step,and metalic antimony can be achieved in cathode directly at the same time The leaching rate of antimony is above 98% Lead of jamesonite is precipitated in the slag in the form of PbCl 2 After changing over with ammonium carbonate and extracting sulphur,the lead concentrate (Pb is above 45%,S is below 15%) and sulphur can be achieved The lead recovery is above 95%,and silver is above 80%
