| 摘 要： | 采用NH3-NH4Cl-H2O体系浸出锌焙砂,经过锌粉两段净化,再电积出低铁金属锌。浸出时Fe、Ge、Si、As、Sb、Pb均进入浸出渣,而Zn、Cu、Cd等进入浸出液中。锌的平均浸出率90.8%,总回收率89.5%。得到的电锌产品中杂质元素Cu、Cd、Sb、As、Ni、Co、Pb和Fe含量≤0.0002%。

| Abstract: | A process of preparing low iron zinc has been studied.The process includes: leaching zinc calcine with ammonia and ammonium chloride solution,purifying with two stage cross-flow and zinc electrowinning.In leaching stage,iron,germanium,silicon,arsenic,antimony and lead remained to stay at residue,but zinc,copper,cadmium dissolved.The average leaching ratio of zinc is 90.82% and total recovery ration of zinc is 89.44%.The impurities of copper,cadmium,antimony,arsenic,nickel,cobalt,lead and iron in zinc are lower than 0.0002%. |
