Bauxite

Occurrence ::A mineral of secondary origin, commonly produced under tropical climatic conditions by the prolonged weathering of aluminum-bearing rocks. Also at times derived from the weathering of clay-bearing limestones. It has apparently originates as a colloidal precipitate. It may occur in place as a direct derivative of the original rock or it m ay have been transported and deposited in a sedimentary formation. In the tropics, deposits, known as laterites, consisting largely of aluminum and ferric oxides are found in t the residual soils. These vary widely in composition and purity but may at time become valuable as sources of aluminum and iron.

Bauxite is not a mineral, but a rock with minerals in it. Bauxite is a sedimentary rock that is an aluminum ore. It is formed in weathered volcanic rocks.

USAGES:
Bauxite is used in aluminum Industries , cement, chemicals, face makeup, soda cans, dishwashers, siding for houses, and other aluminum products.  It is recycled so that it can be used over again.

MINING:

Bauxite consists of 45-60% aluminum oxide, 12-30% water, and various other impurities. Bauxite is typically mined in open-pits and either processed . The water in bauxite is taken out of the ore.  This leaves a white powder that is called alumina which is another name for aluminum oxide.  Alumina is made into aluminum.
