Mining and Refining – Process
The bauxite layer beneath the overburden is broken up using methods such a blasting, drilling and ripping with very large bulldozers Once the bauxite is loosened into manageable pieces it is generally loaded into trucks, railroad cars or conveyors and transported to crushing and washing plants or to stockpiles, before being shipped to aluminaFeb 27, 2019· The Process of Mining Bauxite by Dajcor Aluminum Bauxite is a mineral that contains varying amounts of combined water and several impurities of which ferric oxide and silica are usually predominant It is found in a belt around the equator and is generally extracted by opencast mining Before mining can commence the land needs to be clearedThe Process of Mining Bauxite Dajcor Aluminum Ltd

Bayer process Wikipedia
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef BayerBauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide The aluminium oxide must be purified before it can be refined toThe 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
