PROCESS FOR SIMULTANEOUSLY PREPARING CUPRIC SULFATE AND CALCIUM CHLORIDE FROM CUPRIC CHLORIDE WASTE

摘要

The present invention neutralizes the copper chloride or copper chloride waste solution with calcium carbonate or calcined to obtain calcium chloride and copper hydroxide or copper carbonate, and then filtered to obtain calcium chloride from the filtrate, and the separated copper hydroxide or copper carbonate with sulfuric acid to obtain copper sulfate, This is washed with an alcohol such as methanol to disclose a process for producing copper sulfate of high purity.
