WhatsApp: +86 18838072829Bauxite is Al 2O 2O. Water molecules and other impurities are removed from it to make it pure Al 2O 3. By leaching in the Bayer's process, pure Al 2O 3 obtains. When a sulphide ore is roasted, it turns to oxide ore. Here the ore is oxidized and the ore acts as reducing agent. So sulphate part acts as reducing agent.
