Extraction Process of Aluminium from Bauxite Ore

Other major steps in the process are the precipitation of aluminum hydroxide from the sodium aluminate liquor and the calcination of the aluminum hydroxide to produce aluminum oxide (alumina). In this study the minus 1.5 bauxite ore is ground to minus 3/16 in a Steel Head Rod Mill operating in open circuit.

Bauxite

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium. Bauxite consists mostly of the aluminium minerals gibbsite, boehmite and diaspore, mixed with the two iron oxides goethite and haematite, the aluminium clay mineral kaolinite and small amounts of anatase and ilmenite. In 1821 the French geologist Pierre Berthier discovered bauxite near the

How aluminium is produced

The aluminium production process can be broken down into three stages; first bauxites, which contain aluminium, are extracted from the ground. Second, bauxites are processed into alumina or aluminium oxide, and finally in stage three, pure aluminium is produced using electrolytic reduction, a process in which aluminium oxide is broken down into its components using electric current.

Mining and Refining Aluminum HowStuffWorks

Aluminum isn't found in nature as a pure element. It exhibits relatively high chemical reactivity, which means it tends to bond with other elements to form compounds. More than 270 minerals in Earth's rocks and soils contain aluminum compounds. This makes aluminum the most abundant metal and the third most abundant element in Earth's crust.
