Abstract
Provided herein is a method for smelting high-arsenic copper sulfide concentrate, which comprises the steps of: mixing the high-arsenic copper sulfide concentrate with quartz sand and CaO-containing material to obtain a mixed material; mixing the mixed material with oxygen-containing reactant gas and heating for reaction to obtain matte, slag and SO2-containing flue gas. By the addition of CaO and SiO2 in the smelting process, the concentrate material, the CaO and the SiO2 are allowed to react in the furnace under high temperature. The arsenic sulfides in the concentrate are oxidized first and then chemically react with slagging flux CaO to enter the slag phase in the form of calcium-based compounds of arsenic, iron arsenates and etc., thus reducing the arsenic content in the copper matte.
