It is one of the harmful substances strictly controlled in the national "three wastes" emission standards. Therefore, it is very necessary to carry out comprehensive recovery of cadmium-containing solid waste. In the purification of slag to recover zinc products, there are six major steps: low-acid leaching, iron and arsenic removal, cobalt removal, primary replacement, acid leaching of cadmium, and secondary replacement. The sponge cadmium produced by the primary replacement is loose, and the sponge cadmium slurry has a large water content, which is muddy and the solid is a small particle of cadmium metal agglomerate.
