A large amount of lead-zinc waste residue produced after the smelting of a company's lead-zinc mine contains abundant valuable metal resources.In order to rationalize it,according to the properties of the waste residue,after the harmless treatment of roasting-magnetic separation-flotation process,the valuable products of lead,zinc,iron,carbon and silver are extracted from the lead-zinc waste residue for comprehensive recovery and recycling.At the same time,the tailings are used as raw materials for the production of cement plants and the production of building materials as raw materials for the production of cement and building materials,which realizes the resource utilization of valuable metals in lead-zinc waste residue and the harmless treatment of other wastes,and brings considerable economic benefits to enterprises.
