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

Jan 01, 1982· Jan 01, 1982· In the Explanatory Note to the bauxite geology map of the USSR (1973), a 16member authors' collective subdivided the bauxite deposits into three basic types corresponding to three bauxitic formations, distinguishing within those types some further groups on a morphogenetic basis. (1) Bauxite deposits of the lateritic formations.

Bauxite is a product of weathering. The name bauxite is derived from its first study area. It has been classified into laterite and terrarossa types. The laterite type bauxite is formed in situ from crystalline rocks and is rich in dibbsite. The terrarossa type bauxite overlies limestone of dolomite and is rich in bochmite. Recommended Videos

Bauxite: The principal ore of aluminum. - Geology

Physical Properties of Bauxite. Bauxite is typically a soft material with a hardness of only 1 to 3 on the Mohs scale.It is white to gray to reddish brown with a pisolitic structure, earthy luster and a low specific gravity of between 2.0 and 2.5. These properties are useful for identifying bauxite; however, they have nothing to do with bauxite's value or usefulness.
