| 摘 要： | 硫化铜精矿经浓硫酸用量为１．０－１．４ｋｇ／ｋｇ，在１０５－１４５℃条件下熟化１０－２０ｈ，添加复合氧化剂和催化剂，在一定温度下浸１２０ｍｉｎ，液固比为６，当复合氧化剂ＦＳ３２用量为３７．５－５０．０ｇ／ｋｇ、催化剂ＣＨ１０用量为５ｇ／ｋｇ时，通过溶铜沉铁浸出，其最高浸出率可达９８．４６％，化学浓缩结晶可得到高纯度硫酸铜晶体。

| Abstract: | opper sulfide
concentrate is cured by concentrated sulfuric acid with the ratio of 1.01.4 kg/kg at 105145 for 1020
h,then,adding the compound oxidant FS32 with the ratio of 37.550.5 g/kg and the catalyst CH10
with the ratio of 5 g/kg to the above reactant with l/s=6 at a certain temperature for 120 min.,the
leaching rate can reach to 98.46%.Finally,through concentrating and crystallizing,the high purity
copper sulfate crystal can be obtained. |
