Once mined, the ore is then concentrated using techniques like gravity separation or flotation to increase its antimony content. The concentrated ore is further processed through smelting, where it is heated in a furnace to separate antimony from other impurities, resulting in antimony metal or antimony oxide, depending on the intended application.
