Bauxite | Properties, Formation, Uses » geologyscience

Bauxite is a sedimentary rock mineral that is the primary source of aluminum. It is formed through the weathering of aluminumrich rocks in tropical and subtropical regions. The name bauxite is derived from the French village of Les Baux, where it was first discovered in 1821 by geologist Pierre Berthier. Bauxite is typically found in layers beneath a few meters of overburden, which can vary ...

Aluminium production process

Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with limecaustic soda.
