If the ore contains iron, it is mixed with silica before heating. Iron oxide ‘slags of’ as iron silicate and copper is produced in the form of copper matte which contains Cu 2 S and FeS. FeO + SiO 2 → FeSiO 3 (Slag) Meaning of slag: - During metallurgy, ‘flux’ is added which combines with ‘gangue’ to form ‘slag’. Slag separates more easily from the ore than the gangue. This way,
