| 摘 要： | 呷村铜铅混合精矿中铜、铅矿物主要为黝铜矿和方铅矿,还含有较高的锌、银、砷和锑.本试验针对该矿采用一段氧压浸出综合回收工艺进行处理,通过条件优化实验确定了氧压浸出的操作条件.扩大验证实验表明Cu、Zn的浸出率分别高达98.89%、94.92%,Pb、Ag转化为矾类和硫化物形式留在浸出渣中,铜锌与铅银分离彻底.浸出液中的铜、锌分别通过萃取、电积进行回收.浸出渣中的铅、银通过碳酸盐转化-硅氟酸浸铅-硫脲浸银进行回收.铜萃取率,铅、银浸出率分别为96%、94%和93%. |

| Abstract: | The main copper and lead minerals in complex Cu-Pb bulk concentrate from Sichuan province of China are tetrahedrite and galena,and there are also abundant Pb,Zn,Fe,As and Sb in the concentrate.The concentrate is treated by oxygen pressure acid leaching synthetic reclaiming technique.The best technology conditions are obtained by experiments.It is concluded through the enlarged experiment that the leaching rates of copper and zinc are 98.89% and 94.92% respectively,and that the elements of Pb and Ag transform into sulfate and sulfid depositions.The abruption between Cu,Zn and Pb,Ag is complete.Copper and Zinc are reclaimed with the method of extraction and electrolyse.While lead and silver in the leaching residue are reclaimed through the translation of carbonate first,and then leaching Pb with silicofluoric acid and leaching Ag with thiourea at the last.The extraction rate of copper,leaching rate of lead and silver are 96%,94% and 93% respectively. |
