Bauxite — Wikipédia

La bauxite est une roche latéritique blanche, rouge ou grise, caractérisée par sa forte teneur en alumine Al2O3 et en oxydes de fer. Cette roche constitue le principal minerai permettant la production d'aluminium. Elle se forme par altération continentale en climat chaud et humide. De structure variée, elle contient dans des proportions variables des hydrates d'alumine, de la kaolinite, de la silice et des

Bauxite Market Size, Share Analysis Report, 2020-2027

Bauxite is primarily used as a raw material for alumina production, which is further used as a feedstock for producing aluminum, and therefore the market is primarily driven by aluminum production around the globe. The industry is undergoing significant transformational change, driven by strong demand from China. China dominated the global bauxite industry with a massive revenue share of 58.0% in 2019.

Bauxite an overview ScienceDirect Topics

Bauxite is used in chemical industry, refractory brocks, abrasive, cement, steel, and petroleum. Lateritic bauxite is often used as a building material. The calcined bauxite, produced by sintering of high-alumina in rotary, round or shaft kilns at high temperature, is used as an anti-skid road aggregate which is used in selected areas to prevent road accidents. The largest bauxite ore

Bauxite chemeurope

Bauxite is the most important aluminium ore. It consists largely of the minerals gibbsite Al(OH) 3, boehmite γ-AlO(OH), and diaspore α-AlO(OH), together with the iron oxides goethite and hematite, the clay mineral kaolinite and small amounts of anatase TiO 2.It was named after the village Les Baux-de-Provence in southern France, where it was first discovered in 1821 by geologist Pierre Berthier.

Bauxite (Saline County) Encyclopedia of Arkansas

The story of Bauxite (Saline County) is largely the story of the bauxite mining industry. Bauxite, the ore from which the town derives its name, and which is a key component in the production of aluminum, was discovered in great abundance in this area of central Arkansas in 1887. The company that became Alcoa, which mined the ore, not only provided plants and mills but also provided a

Bauxite mining in Australia Wikipedia

Industry influences. Global demand for alumina. Bauxite is currently the only economically viable raw material to produce alumina. Therefore, any shifts in demand for alumina will also create shifts in demand for the bauxite industry in Australia. This could be increased demand for bauxite ore so countries can produce their own alumina or increased demand for alumina, which would increase

Bauxite Wikipedia

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH) 4) and small

ARTICLE: Addressing the Challenge of Bauxite Residue

The largest waste by-product generated in the Bayer bauxite refining process is bauxite residue, commonly called red mud. An enormous quantity of caustic red mud is generated worldwide every year, posing a very serious and alarming environmental and safety problem. The storage of red mud is a challenge for alumina refineries (Figure 1), as storage pond dams sometimes collapse and/or fail due
