以硫酸化焙烧 水浸 浓缩结晶工艺从含砷的硫化铜物料中回收硫酸铜。试验结果表明，该工艺技术指标稳定，成本低；硫酸铜产品质量符合国标一级品要求；铜浸出率达９７－４７ ％ ，砷、锑、铋等金属集中于渣中，可进一步回收
Recovery of Copper Sulphate from Arsenic - Containing Copper Sulfide by Sulfation Roasting and Water Condensation Concentration. The test results show that the technical indicators of the process are stable and the cost is low; the quality of the copper sulfate product meets the requirements of the first grade of national standard; the leaching rate of copper reaches 97-47%; the metals such as arsenic, antimony and bismuth are concentrated in the slag for further recovery
