What is the composition of 'Copper matte'?

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 ).

What is Copper Matte? - Chemistry Q&A

Copper matte is a mixture of copper sulfide (Cu 2 S) and some iron sulfide (FeS). Matte is a process in which copper is extracted before the final reduction. when a hot blast of air is blown through a molten matte placed in a silica lined converter, FeS of the matte oxidizes to FeO. This FeO combines with SiO 2 (silica) to produce FeSiO 3;(slag).
