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.
