Used For Mining Bauxite

What is Bauxite? - Mineral, Formula, Uses with Videos and

2022-1-3  Bauxite is an aluminium-rich ore used for the manufacture of aluminium (metallurgical bauxite) and refractory products, chemicals or cements. Bauxite is a prime important raw material for the primary aluminium industry. It is also used in a number of non metallurgical sectors, like refractory, abrasive, cement, steel making and chemicals.

Bauxite - an overview ScienceDirect Topics

Bauxite (Fig. 1.33) is formed by surface weathering of clay rocks around the tropical region and composer of aluminum oxide (Al(OH) 3).It contains 15%–25% aluminum and only ore used for commercial extraction for aluminum. The bauxite occurs as near-surface layers and usually mixed with clay minerals, iron oxide, and titanium dioxide.
