The aluminium production process starts with the mining of bauxites, an aluminium rich mineral in in the form of aluminium hydroxide. About 90% of global bauxite supply is found in tropical areas. ALUMINA PRODUCTION

The production of the metal Aluminum from the raw ore of Bauxite is a two stage process. Stage 1 Converting Bauxite to Alumina STEP 1 - Crushing and Grinding: Alumina recovery begins by passing the bauxite through screens to sort it by size.

Approximately four tons of high-grade bauxite yield two tons of alumina, from which one ton of aluminum is produced. Extraction and refining. The production of aluminum from bauxite is a two-step process: refining bauxite to obtain alumina and smelting alumina to produce aluminum. Bauxite contains a number of impurities, including iron oxide, silica, and titania.

This process involves immersing the aluminum workpiece into an electrolytic solution and introducing an electric current to deposit dissolved ions of another metal onto the surface. An alternative to the aluminum electroplating process is electroless plating, which does not require electricity to deposit the metal ions.

Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite. To produce pure aluminum, alumina is smelted using the Hall–Héroult electrolytic process.

This simple process is the basis for producing aluminum plate, sheet and foil. Sheet, the most widely used form of industrial aluminum, is used in applications including aerospace (the skins of planes), transportation (auto body sheet), packaging (can bodies and ends) and construction (building facades).
