| titleOfInvention | Smelting method of high arsenic copper sulfide ore |
| abstract | A method for smelting a high arsenic copper sulfide concentrate capable of producing a mat having a low arsenic content is provided. Mixing a high arsenic copper sulfide concentrate with silica sand and a CaO-containing material to obtain a mixed material; mixing the mixed material with an oxygen-containing reaction gas and heating to react; mat, slag and Obtaining SO2 containing exhaust gas. By adding CaO and SiO2 in the smelting process, the concentrate materials, CaO and SiO2, can react in a high temperature furnace. Arsenic sulfide in the concentrate first oxidizes and then chemically reacts with the slagging flux CaO to enter the slag phase in the form of calcium-based compounds such as arsenic, iron arsenate, and thereby in the copper matte Arsenic content is reduced.
