Copper Matte is the mixture of copper sulphide (C u 2 S) and some iron sulphide (F e S). Matte is the phase where copper is extracted prior to the final reduction. The roasted ore is mixed with coke and silica (sand) S i O 2 and is introduced in to a blast furnace. The hot air is blasted and F e O is converted in to ferrous silicate (F e S i O 3).

Copper matte is made up of copper sulfide (80-95 percent) and Fe – Co alloys (five to seventeen percent). Metallic copper, silver, Pb – Ag alloys, and arsenide can all be found in addition to Fe – Co. Finally, the copper matte is a mixture of copper sulfide and a small amount of iron sulfide recovered during the matte process.
