| description | The invention discloses a method for recovering zinc through combined treatment of zinc-containing waste residues and aluminum electrolysis overhaul residues, which comprises the following steps of: mixing the zinc-containing waste residues, the overhaul residues and a fluorine fixing agent, heating in a muffle furnace, reacting the mixed material at high temperature, reducing zinc into simple substances, and exchanging the simple substances; and then reacting with oxygen in the air to generate zinc oxide so as to realize zinc recovery. According to the method, the zinc-containing waste residues and the aluminum electrolysis overhaul residues are combined, efficient recovery of zinc is effectively achieved, meanwhile, harmful substances such as soluble fluoride and cyanide in the aluminum electrolysis overhaul residues are converted into stable compounds or decomposed into harmless substances in the high-temperature roasting process, harmless treatment of the aluminum electrolysis overhaul residues is achieve |
