Treatment method of zinc sulfate leach solution

The invention discloses a treatment method of a zinc sulfate leach solution, which comprises the following steps: A) adding zinc into a zinc sulfate leach solution to carry out replacement reaction, and carrying out solid-liquid separation on the zinc sulfate leach solution to obtain copper concentrate and a medium supernatant; and B) removing iron from the medium supernatant, and purifying to obtain purified residues. The treatment method of a zinc sulfate leach solution can greatly enhance the recovery rate of copper in the zinc sulfate leach solution, and greatly enhance the grade of the recycled copper concentrate.
