bauxite

Description

The scientific name bauxite ore, bauxite, bauxite.Its composition is extremely complex, a variety of geological sources vary the floorboard of the hydrous alumina ore.As water soft LvShi, hard LvShi monohydrate and sanshui LvShi (Al2O3 · 3 h2o);Have a plenty of diaspore and kaolinite (2 sio2, Al2O3, 2 h2o) company;Some is given priority to with kaolinite, and with higher content of kaolinite, the form for general bauxite or kaolinite clay.Bauxite is generally formed by the chemical weathering or exogenous, there are few pure mineral, mineral always contains some impurities, more or less contain clay minerals, iron ore, titanium minerals and clastic heavy minerals and so on.
