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 .

Aluminium is made from bauxite, or aluminium ore. Bauxite is the basic raw material that is refined into alumina, which in turn is sent to smelters for processing into aluminium. First discovered near Les Beaux in the South of France in 1821, bauxite was initially called "beauxite". In 1886, Charles Martin Hall and Paul Héroult independently developed a process for making .
