Some alumina is still produced by melting bauxite in an electric furnace, in a process devised for the abrasives industry early in the 20th century, but most is now extracted from bauxite through the Bayer process, which was developed for the aluminum industry in 1888.In the Bayer process bauxite is crushed, mixed in a solution of sodium hydroxide, and seeded with crystals to precipitate ...
Bauxite, the raw material for the production of alumina, was first discovered in 1924 at Kijang, Bintan Island, in the province of Riau, in northwestern Indonesia. Bauxite from Bintan Island has been mined and exported since 1935. In 1968 ANTAM acquired the mine. Thus, ANTAM is Indonesia's longest running producer of bauxite.
Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts. The principal aluminum hydroxide minerals found in varying proportions with bauxites are gibbsite and the polymorphs boehmite and diaspore.
Bauxite also known as bauxite or bauxite, the main component is alumina, is containing impurities hydrated alumina, is a clay mineral. White or off-white, brownish yellow or reddish because of iron content. Density 3.45g/cm3, hardness 1 ~ 3, opaque, brittle. Extremely difficult to melt.

4.1.1 Bauxite Grinding and Slurry Storage Bauxite is ground to less than 1.5 mm particle size at the refinery, using semi-autogenous grinding mills (SAG and/or Ball mills) to ensure sufficient solid-liquid contact during the digestion phase, which improves alumina extraction efficiency. A solution of hot
Bauxite is a mixture of hydrated alumina, aluminum hydroxide, clay minerals, and insoluble materials such as quartz, hematite, magnetite, siderite, and goethite. The aluminum minerals in bauxite include: gibbsite Al(OH) 3, boehmite AlO(OH) and diaspore AlO(OH).
Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature (from 850 °C to 1600 °C). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina …
