The alumina content of bauxite ores varies from one deposit to another, and methods of treatment differ accordingly (see ). This means that each alumina plant is almost tailormade to suit a particular bauxite. The processes are nevertheless basically similar, and a general description is given in the following. The bauxite from the mine is crushed and ground. It is then mixed with a ...

Alumina, or aluminium oxide, is extracted from the bauxite through refining. Alumina is separated from the bauxite by using a hot solution of caustic soda and lime. The alumina mixture is heated and filtered and the remaining alumina dried to a white powder. Alumina is transported by ship to the specially designed berth in the Port of Newcastle before being taken to the smelter to be made into ...
