Bauxite is a mineral that contains varying amounts of combined water and several impurities of which ferric oxide and silica are usually predominant. It is found in a belt around the equator and is generally extracted by open-cast mining. Before mining can commence the land needs to be cleared of timber and vegetation.
Lateritic bauxite is often used as building material when no other materials are available. Calcined bauxite is used by construction companies as an anti-skid road aggregate which is used in selected areas to prevent accidents. 4. Other Uses. Bauxite has limited uses but the wide application in paper making, water purifying, and petroleum refining.
