bauxite de classification

Bauxite Wikipedia

Numerous classification schemes have been proposed for bauxite but, as of 1982, there was no consensus.. Vadász (1951) distinguished lateritic bauxites (silicate bauxites) from karst bauxite ores (carbonate bauxites):. The carbonate bauxites occur predominantly in Europe, Guyana, and Jamaica above carbonate rocks (limestone and dolomite), where they were formed by lateritic weathering and

Classification of Bauxite Deposits ScienceDirect

1982-01-01· The classification adopted in the final analysis thus reflects some of the features of Vadász', Valeton's, De Weisse's, Kirpal's and Bushinsky's classifications and of the Soviet classification of 1973. From each, the writer has gleaned the factors that he deemed to be the most realistic. The principal difference is that all bauxites overlying carbonate rocks have been united into

Bauxite: The principal ore of aluminum.

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. This is because bauxite is almost always processed into
