On some surface deposits there is no overburden, and on others, the bauxite may be covered by up to 20 metres of rock and clay On average, overburden thickness is around 2 metres The bauxite layer beneath the overburden is broken up using methods such a The bulk of world bauxite production (approximately 85%) is used as feed for the manufacture of alumina via a wet chemical caustic leach method commonly known as the Bayer processBauxite and Alumina Statistics and InformationObjective: To describe bauxite mining and alumina refining processes and to outline the relevant physical, chemical, biological, ergonomic, and psychosocial health risks Methods: Review article Results: The most important risks relate to noise, ergonomics, trauma, and caustic soda splashes of the skin/eyes Other risks of note relate to fatigue, heat, and solar ultraviolet and for some Bauxite mining and alumina refining: process description

Mining and Refining – Energy Efficiency
Bauxite mining requires relatively low energy inputs, compared to other steps in the aluminium production process – with less than 15 kilograms of fuel oil (mainly in the form of diesel for haul trucks) and less than 5 kWh of electricity consumed per tonne of bauxite extractedBauxite is mined at St Ann and the ore is transported via railway to Port Rhoades There, it is dried and shipped to its customers A considerable portion of the bauxite mined at St Ann is shipped to the Gramercy refinery in Louisiana, where it is refined into aluminaBauxite Alumina Plants – Jamaica Bauxite Institute (JBI)Alumina processing in Tayan will produce chemical grade alumina products by processing bauxite ore through the Bayer process into alumina products with a capacity of 300,000 metric tons of Al2O3 (alumina) base per year The Bayer process consists of three stages, namely Liquor Clarification process, Precipitation Process, and Calcination ProcessPT ANTAM Tbk Bauxite Alumina

Mined bauxite ore is refined into alumina, through what is known as the Bayer process The Bayer process, discovered in 1887, extracts alumina from bauxite through crushing, dissolving it in caustic soda, filtration and an electrolytic process A white powder, similar to table salt, called alumina is produced and can then be smelted into 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 electrolysisBauxite WikipediaBauxite is mined near the town of Boddington, 130 kilometres south east of Perth The bauxite is transported to the alumina refinery via an overland conveyor system that stretches more than 50 kilometres The refinery extracts alumina using a fourstage Bayer process This process turns the red bauxite rock into white alumina powderWorsley Alumina Mine
