2014-5-8 Washing and beneficiation (further treatment of the ore to concentrate the minerals) if necessary. Delivery to export or to local refineries. Approximately 165 million tonnes of bauxite are mined each year. Bauxite is generally transported to refineries by conveyor, rail, or ship. Some alumina refineries are located close to their bauxite mines.
