Aluminium smelting is an industrial process used to extract the metal aluminium from aluminium oxide, or alumina The first step in this process involves processing raw ore to produce purified aluminium oxide This can include washing, grinding, and treating

Discovery of aluminium ore. In 1821 Geologist Pierre Berthier discovered reddish clay rock deposits in France. The rock was named bauxite after Les Baux, the area where it was found. HenriEtienne SainteClaire Deville, an outstanding French chemist and technologist, transferred the chemical method of aluminium creation discovered by scientists to industrial appliion. .

 · After alumina is extracted from bauxite ore, further processing called 'smelting' is necessary to convert it into aluminum. In this process, alumina is dissolved in a solution and a strong electric current is applied. This process has generally remained unchanged since its invention in 1886. Because smelting requires significant amounts of electricity, some primary aluminum smelters can .

The ore is loaded into autoclaves and treated with lime–caustic soda. Aluminium oxide appears in the resulting slurry while all the admixtures settle to the bottom as red mud. The sodium aluminate solution is stirred in precipitators for several days, eventually pure alumina or Al 2 O 3 settles at the bottom. REDUCTION PROCESS. At an aluminium smelter, alumina is poured .
