Methods Of Mining Bauxite
The Juruti bauxite mining area is among the first places in Brazil to use the nucleation method of environmental conservation. Alcoa began using the technique last August on a 70 ha area there. In about two years, the area will have an understory favorable to the introduction of new species, like Brazil nut trees, andiras, trumpet trees, copaibas and others.

Bauxite Mining Processing. Bauxite is the principal ore of alumina (Al2O3), which is used to produce aluminum. Bauxite is one of the most abundant elements on earth and contains nearly 25-30% of alumina. Its typically found near the equator in tropical and subtropical regions, in the form of horizontal layers beneath a few meters of overburden.
