硫化氢脱除镍钴溶液中锌杂质研究

Research on Removing Zinc from Nickel and Cobalt Acid Pressure Leaching Solution by H_2S

针对镍钴加压浸出液,通过硫化物沉淀溶度积的不同,采用硫化氢对镍钴溶液中的锌、铜进行沉淀,除锌铜率≥80%,镍损失率≤1%,达到选择性除锌的效果。

According to the diffidence of the solubility product, the zinc and copper should be precipitated by H_2S in the nickel and cobalt acid pressure leaching solution. The precipitation rates of zinc and copper are beyond 80% with the loss rate of nickel is below 1%.
