| description | The invention provides a method for treating high-iron-content copper sulfate mother liquor, and relates to the technical field of waste liquid treatment. The method specifically comprises the following steps: (1) putting a copper sulfate mother solution with high iron content into a replacement reaction kettle, and adding a waste hard alloy material containing iron and copper; (2) heating to a proper condition, and carrying out replacement reaction on iron in the hard alloy material and copper ions in the mother liquor; (3) after the reaction is finished, filtering the solution in the reaction kettle, collecting the filtrate, placing the filtrate in a ferrous sulfate crystallization system, and crystallizing to obtain a ferrous sulfate byproduct; and (4) collecting a filter cake in the reaction kettle to obtain a copper sponge product. Furthermore, the copper sponge obtained through replacement can also be used as a raw material for preparing copper sulfate, and copper sulfate with the purity larger than or |
