The invention relates to a method for producing electrolytic zinc by using cobalt-rich residue. In the method, cobalt-containing purified residue produced in a cobalt removal process of electrolytic zinc purification is used as a main raw material to realize production of manganese-free electrolytic zinc; the cobalt-containing raw material and sulfuric acid are neutrally leached according to a certain proportion; pressure filtration is performed by using a pressure filter; the manganese-free electrolytic zinc is produced from qualified zinc liquid obtained by performing cobalt removal, purification and deep purification on the neutral leaching solution; neutral leaching residue is then leached with a strong acid at a high temperature; and metal zinc is fully recovered. By means of the method provided by the invention, the cobalt-containing waste residue produced during the electrolytic zinc production can be fully utilized, and a product is obtained to fulfill the aims of changing a waste ...
