Bauxite - an overview | ScienceDirect Topics
The more severe conditions will also extract trihydrate alumina from bauxite so the deciding factor for the digestion conditions required is the presence of a significant concentration of monohydrate alumina content. Fortunately, trihydrate alumina is the dominant aluminum species present in the major world deposits of Africa, Australia, the Caribbean, Central and South America, and the U.S.A. European bauxites are mainly the monohydrate.
Bauxite – Alufer Mining Limited
Bauxite is the main commercial mineral from which aluminium oxide is extracted, which in turn is smelted to form aluminium metal. Typically, a bauxite resource contains 30-60% alumina (Al 2 O 3), and occurs as two main types: trihydrate (“low temperature”) bauxite and monohydrate (“high temperature”) bauxite

Aluminium hydroxide - Wikipedia
The residue or bauxite tailings, which is mostly iron oxide, is highly caustic due to residual sodium hydroxide. It was historically stored in lagoons; this led to the Ajka alumina plant accident in 2010 in Hungary, where a dam bursting led to the drowning of nine people. An additional 122 sought treatment for stone burns. The mud contaminated 40 square kilometres (15 sq mi) of land and ...
Calcined Bauxite — Alchemy Mineral
Calcined Bauxite’s thermal stability, high mechanical strength and resistance to molten slags make it an ideal raw material in the production of many refractory, abrasive and specialty product applications. Typical applications are aluminum production, abrasives, cement, ceramics & flooring.
METHOD FOR PROCESSING BAUXITE RICH IN …
09.08.2001 · [0006] Bauxite containing alumina in the monohydrate state (boehmite, diaspore) is more difficult to digest than trihydrate bauxite and is treated according to the Bayer process at temperatures higher than 200° C., usually between 220 and 300° C. Bauxite containing alumina in the trihydrate state (gibbsite) is treated at temperatures below 200° C., usually between 100 and 170° C.
Bauxite 101 | The Bauxite Index
Bauxite Occurrence Based on a broad geological assessment the potential for bauxite mineralisationis quite common across the globe.Typically deposits in the tropics and southern temperate zones are lateritic deposits, while those in the northern temperate zones and beyond are monohydrate deposits, often associated with karst systems.

Jamaican Bauxites – Jamaica Bauxite Institute (JBI)
The latter in often present in insignificant amounts, but in some areas, the monohydrate form may exceed 5% by weight of the total bauxite. The proportion of trihydrate to monohydrate is of considerable importance since the processing characteristics of monohydrate bauxite is markedly different from that of trihydrate bauxite. The gibbsite content of Jamaican bauxite ranges from 34-46%, whereas …
Frequently Asked Questions - Australian Bauxite …
Boehmite and diaspore have the formula AlO(OH), which is monohydrate. The main mineral of aluminium in our bauxite deposits is gibbsite. Large bauxite deposits in China and Vietnam are either low grade, high in monohydrate minerals, and/or high in reactive silica. Dissolution of monohydrate minerals requires higher temperatures and higher concentration of caustic soda; energy consumption …
Precipitation of monohydrate alumina in the …
The production of alumina by the Bayer process involves three main steps: digestion of bauxite, precipitation of aluminum trihydrate (gibbsite, Al2O3.3H2O) from the resulting solution and calcining of the gibbsite at 980 - 1200oC to produce alumina. The calcination step absorbs 3 GJ/t alumina or 25% of the total Bayer process. The objective of the current project is to develop a highly ...
