Bauxite is a sedimentary rock mineral that is the primary source of aluminum. It is formed through the weathering of aluminum-rich rocks in tropical and subtropical regions. The name bauxite is derived from the French village of Les Baux, where it was first discovered in 1821 by geologist Pierre Berthier. Bauxite is typically found in layers beneath a few meters of …
Bauxite ore is the world's primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Bauxite is a rock formed from a reddish clay material called laterite soil and is most commonly …
According to the grade of the bauxite ore, 2–3 tonnes of ore yield one tonne of alumina and about one tonne of red mud (dry weight). When designing an alumina plant, factors other than the type of bauxite ore to be used as feed material and the form of alumina to be produced have to be taken into consideration. A high silica content of the ...
Bauxite production of 54.6 million tonnes in 2023 was unchanged from 2022. Operations saw a continued improvement in the fourth quarter, with production 8% higher than the prior quarter, following the challenges of higher-than-average rainfall at Weipa in the first quarter and equipment downtime at both Weipa and Gove in the first half.
Primary aluminum production begins with the mining of bauxite ore, a hydrated oxide of aluminum consisting of 30 to 56 percent alumina (A l2O3) and lesser amounts of iron, silicon, and titanium. The ore is refined into alumina by the Bayer process. The alumina is then shipped to a primary aluminum plant for electrolytic reduction to aluminum.
Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches …
Bauxite discovered near Les Beaux in southern France by Pierre Berthier: 1847: Armand Dufrénoy names the ore "beauxite" ... The aluminium-containing bauxite ores gibbsite, böhmite and diaspore are the basic raw material for primary …

The principal ore of aluminum is bauxite, a complex mixture of a number of aluminum hydroxides and hydrous aluminum oxides. Office of the State Geologist. Home (current) ... Mining of bauxite for metal production began in …
Bauxite is the principal ore of aluminum. Bauxites vary physically according to the origin and geologic history of their deposits: some deposits are soft, easily crushed, and structureless; some are hard, dense, and pisolitic, or …
Bauxite, an aluminum ore, is the world's main source of aluminum.It consists mostly of the minerals gibbsite Al(OH)3, boehmite γ-AlO(OH) and diaspora α-AlO(OH), mixed with the two iron oxides goethite and haematite, the clay mineral kaolinite and small amounts of anatase TiO2, Ilmenite, FeTiO3, and FeO TiO2.
The production volume of bauxite in the North American country has been on a continual annual decline since 2018. Bauxite ore is the main source of aluminum worldwide. It contains alumina (in ...
Bauxite is the ore for the bulk metal aluminium. The World Bank identified aluminium as the 'high-impact, cross-cutting metal' that has the highest production levels compared to all other metals deemed significant to the Clean Energy Transition, with cumulative production reaching 102 million tons by 2050 to primarily supply solar PV and then other …
China accounts for 22% of global production, with the largest producers being the Republic of Guinea, Australia, China and Brazil.
