bauxite extraction from silica sand Bauxite: The principal ore of aluminum. Many people are surprised to learn that bauxite is a rock and not a mineral. It is a rock formed from a laterite soil that has been severely leached of silica and other Almost all of the aluminum that has ever been produced has been extracted from bauxite.

et al., 2008), and Turkey (Dilek et al., 2013)) can be used to remove fluoride from drinking water at significantly lower costs than activated alumina. Bauxite ore is composed largely of aluminum hydroxides, along with significant or trace quantities of iron, silicon, and sometimes calcium and titaniumoxides. Our previous research shows that

decomposition of carbonate gaand, as in the calcination of limestone to drive off carbon dioxide; decomposition of hydrated minerals, as in the calcination of bauxite and gypsum, to remove crystalline water as water vapor; decomposition of volatile matter contained in raw petroleum coke;

Most bauxite are orange to red in colour, because iron is the predominant second element, present mostly as red hematite Fe2O3 and yelloworange goethite AlO(OH). Iron is usually followed (in typical order of abundance) by silicon, titanium, calcium (high in karst bauxites only), phosphorus and vanadium.
