    Cu 2 O + C → 2 Cu + CO In actual process, the ore is heated in a reverberatory furnace after mixing with silica. In the furnace, iron oxide 'slags of' as iron silie and copper is produced in the form of copper matte. This contains Cu 2 S and FeS. FeO + SiO 2 → FeSiO 3 (Slag) Copper matte is then charged into silica lined convertor.

    These are heated by combusted fuel or electric current to a temperature of 1,230–1,300 °C (2,250–2,370 °F), producing an artificial copperiron sulfide that settles in a molten pool at the bottom of the furnace. The sulfide material, known as matte, contains from 45 to 70 percent copper, depending on the particular process.

  • Why copper matte is put in silica lined converter?

    Copper matte is put in a silicalined converter to remove the remaining FeO and FeS present in the matte as slag (FeSiO 3 ). Also, some silica is added to the silicalined converter. Then, a hot air blast is blown. As a result, the remaining FeS and FeO are converted to iron silie (FeSiO 3) and Cu 2 S is converted into metallic copper.
