Deine the term slag.
During metallurgy 'Flux’ is added which combines with ‘gangue’ to form ‘slag’. Slag separates more easily from the ore than the gangue. Slag is fusible mass, which usually floats over molten metal, obtained by the reaction of the flux with impurities present in the concentrated ore.
CaO + SiO2 → CaSiO3
