bauxite to aluminium plant manufacturing
TENORM: Bauxite and Alumina Production Wastes Radiation
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 alumina.

Alumina Refining The Aluminum Association
Alumina is the common name given to aluminum oxide (Al 2 O 3). Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite.
Bauxite The Aluminum Association
ResourcesEnvironmentFutureDiscoveryBauxite ore is the worlds primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal. Bauxite is typically found in topsoil located in various tropical and subtropical regions. The ore is acquired through environmentally responsible strip-mining operations. Bauxite reserves are most plentiful in Africa, Oceania and South America. Reserves are projected to last for ce
ARTICLE: Addressing the Challenge of Bauxite Residue
Mar 11, 2019· Bauxite ore contains 30-60% aluminum oxide (Al 2 O 3). In the Bayer process (Figure 2), the bauxite is digested in a pressure vessel along with a sodium hydroxide solution (caustic soda) at an elevated temperature, which dissolves the aluminum oxide converting it into sodium aluminate, leaving insoluble red mud solids as a by-product.
How aluminium is produced
The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide Al2O3, a white powder. The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today.

Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden. As of 2010,approximately 70% to 80% of the world's dry bauxite production is processed first into alumina and then into aluminium by electrolysis. Bauxite rocks are typically classified according to their intended commercial application: metallurgical, abrasive, cement, chemical, and refractory.
