Crushing, Grinding and Concentration of the Ore
Most of the elements do not occur in the free state in nature but these occur in the combined states. In the combined states, metals are usually found in the oxidised form (e.g., Fe2O3, MnO2, SnO2etc.), while non-metals occur in the reduced form such as halide ions (Cl¯, Br¯, I¯). The metals can be obtained from their oxidise…
