摘要
针对镍钴加压浸出液,根据溶液中硫化物沉淀溶度积的不同,采用硫化氢为沉淀试剂沉淀镍钴溶液中的锌,整个过程没有引入其它杂质,锌去除率大于98%,而镍损失率小于1%,选择性除锌效果好。
According to the difference of the solubility product, H2S was used to make zinc in the nickel and cobalt acid pressure leach liquor precipitated. No metallic impurities were drawn into leach liquor. The removal efficiency of zinc is more than 98% and the precipitation loss rate of nickel is less than 1%. This process has a good selectivity for the removal of zinc.
