一、前言国际镍公司汤姆逊厂日产电镍150吨。电解槽排出的阳极液温度为60℃,PH值为1.9,含铜0.5克/升及其他杂质。现在采用化学沉淀法净化阳极液。采用硫化氢除铜(4.6吨/日)及少量砷。然后采用硫化镍粉中和,通氯气氧化除钴、铁。硫化铜滤饼中含大 I. Introduction International nickel company Thomson plant Nissan nickel 150 tons. Electrolytic cell discharge anolyte temperature of 60 ° C, PH value of 1.9, containing 0.5 g / liter of copper and other impurities. Now use chemical precipitation to purify the anolyte. The use of hydrogen sulfide copper (4.6 tons / day) and a small amount of arsenic. Then nickel sulfide powder and neutralization, through chlorine oxidation of cobalt, iron. Copper sulfide cake containing large
