Chapter 2. Production and Processing of Aluminum

1999-5-7  Bauxite occurs mainly in the tropics and in some Mediterranean countries. Today, the main mining locations are in Latin America, Australia, India, and Africa. Bauxite is a weathered rock containing two forms of hydrated aluminum oxide, either mostly a monohydrate AlO(OH) in caustic bauxite, or mostly a trihydrate Al(OH) 3 in lateric bauxite.

Kinetic Modelling of Different Bauxite Types in the Bayer

2013-7-18  The dissolution of aluminum hydroxides from bauxite ores constitutes a key process in the aluminum industry. Generally, aluminum minerals in bauxites are present in the form of gibbsite, boehmite or diaspore. Usually, these mineral forms are mixed in bauxite as a boehmite-diaspore or a gibbsite-boehmite mixture with different weight ratios.

Approximately 98% of the alumina produced worldwide is manufactured via the Bayer process, which consists of digestion and calcination. Initially, the bauxite is washed and ground. During digestion, the bauxite is dissolved in caustic soda (sodium hydroxide) at high pressure (40–220 bar) and at high temperature (120–300°C).
