Bauxite - ALS

There are two types of bauxite deposits. Both are a result of chemical weathering: 1. Lateritic These are the silicate bauxites formed in situ from weathering of various aluminous silicate rocks such as granite, gneiss, basalt, syenite, and shale. They are found mostly in tropical and temperate regions and occur primarily on plateau surfaces and hill slopes. Most are residual accumulations ...

Bauxite - an overview ScienceDirect Topics

Bauxite is essentially hydrated alumina in an ore-specific (every bauxite mine is different) blend of its three common mineral forms: gibbsite Al(OH) 3, boehmite γ-AlO(OH), and diaspore α-AlO(OH), combined with many impurities, most commonly clay, silica, iron oxide, and titanium dioxide.

SUSTAINABILITY IN ALUMINA PRODUCTION FROM BAUXITE

different types of bauxites (from specific regions) in the Bayer process are presented in Table I. Obviously, red mud production in the Bayer process causes a direct loss of the iron and aluminum units contained in the ore. The Red Mud production indeed represents an environmental problem because of its alkalinity and being stockpiled/stored in holding ponds.4 The process residue (slurry) must ...

Management and use of bauxite residue

of bauxite residue was stored in lagoon-type impoundments and the practice is still carried out at some facilities. In this method, the bauxite residue slurry from the mud washing circuit is pumped, with a solids content of 20 to 30%, into storage areas created by dams and other earthworks for secure containment. In many instances valleys were dammed for example, Ewarton (Jamaica), see Figures ...

Bauxite — Wikipédia

La bauxite est une roche latéritique blanche, rouge ou grise, caractérisée par sa forte teneur en alumine Al 2 O 3 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 ...

DRY BENEFICIATION OF BAUXITE MINERALS USING A

The terms trihydrate and monohydrate are commonly used by industry to differentiate various types of bauxite. Bauxite that is totally or nearly all gibbsite bearing is called a trihydrate ore; if boehmite or diaspore are the dominant minerals it is referred to as monohydrate ore [3]. Mixtures of gibbsite and boehmite are common in all types of bauxites, boehmite and diaspore less common, and ...
