Abstract:About 11.0 billion tons solid wastes were produced in 2021 in China, in which 4.0 billion tons came from industries, and about 1.2 billion tons solids contained valuable metals with potential comprehensive utilization. This paper focus on typical solid wastes with multi-metals and introduced the technologies of reused and harmless treatment including solids containing arsenic from copper smelters, residues from lead and zinc plant, spent Li battery, spent catalysts, electroplating sludge and cyanide residues. At present, the disposal system of typical solid waste, especially hazardous waste, has been initially established in China, but there are some problems such as insufficient disposal capacity, uneven technical equipment, incomplete treatment, and poor economy etc. The future development trend will be toward large-scale plant, harmless with high temperature, and collaborative smelting.
