Abstract:In the electrolytic process of copper refining, part of the waste electrolyte needs to be treated with copper removal and impurity removal. In order to improve the direct yield and cost saving of high-purity copper products in the electrolytic cleaning process of Xiangguang Copper Industry, the initial copper sulfate production process, electrodeposition copper and impurity removal process and nickel sulfate production process are reformed. Finally, the original production of copper sulfate and part of high impurity electrodeposition copper and high impurity copper containing materials are optimized to produce high purity grade A copper and high purity copper powder.
