bauxite ore mining and processing
Mining and Refining – Process
Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which include washing, wet screening and mechanical or manual sortingThe Bayer Process The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the aluminaTENORM: Bauxite and Alumina Production Wastes | Radiation
