Jan 07, 2018 Bauxite is the primary feedstock for an alumina refinery to extract aluminium oxide using the Bayer process. Generally, around 2 to 3 tonnes of bauxite is required to produce one tonne of alumina. Aluminium metal is subsequently extracted from alumina in a smelter via electrolysis through the HallHeroult method.

Extraction Process of Aluminium from Bauxite Ore

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

Alumina is converted into primary aluminium through a smelting process by using electrolytic reduction. From the pot-line, the molten aluminium is routed to either the casting units, where the aluminium can be cast into ingots, sow ingots, tee ingots, billets, wire rods, cast strips and alloy ingots, or to RPU where the molten aluminium is

An estimated 80% of the water safely collected and treated at Alunorte is rainwater – coming either from the refinery area or from the rainwater basins of the bauxite residue deposits. Only about 15% of the water that passes through the water treatment system is water stemming from the production of alumina.

Aluminum rod and bar is produced by several different processes namely extrusion, rolling and coiling, or drawn directly from molten aluminum. These processes elongate the aluminum into circular or bar-shaped pieces that can be machined into all kinds of applications.

ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites.
