The Process of Mining Bauxite
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.
