WebMay 7, 2024 · The pyrometallurgical copper-making process consists of four steps in which the concentrate of polymetallic sulfides is refined into copper. These four steps are[2,3,4,5]: Smelting This is a continuous oxidative-smelting process that produces two immiscible liquids: slag and copper matte.
WebThe primary purpose of matte smelting is to melt and recombine the charge into a homogeneous matte of metallic copper, nickel, cobalt, and iron sulfides and to give an iron and silicon oxide slag. It is done in many types of furnace on both roasted or unroasted sulfide feed material. The reverberatory furnace is essentially a rectangular refractory … WebCopper Matte is the mixture of copper sulphide and some iron sulphide. Matte is the phase where copper is extracted prior to the final reduction process converting it to crude copper . The composition of copper matte is:-. 5 – 17 % metallic copper, Fe-Co alloys, metallic silver, galena, Pb-Ag alloys, Pb-Ni alloys, Pb-Cu alloys and arsenides.
