Copper concentrate (CuFeS 2) is fed into the furnace along with a flux of silica sand, SiO 2, and oxygen, O 2. The flux is used to control the chemistry of the slag. In particular, it causes the iron (Fe) in the copper concentrate to accumulate in the slag phase, while the copper (Cu), accumulates in the matte phase. Copper Concentrate
