· For 1 t of metal production, approximately 2 t of alumina is required, which is obtained through processing 5–6 t of bauxite ore. Large amount of power is consumed for smelting of aluminum, which is mostly provided by coal-based power plants. For this, about 8–12 t of coal is needed per ton of aluminum produced.

Deposits are classified into karstic and “sedimentary” (paralic) bauxites. The estimated 2400–2500 Mt of total reserves/resources are scattered over a huge area. Because of the high silica and in some cases high sulfur content the bauxite needs beneficiation or selective mining in many cases.
Consulta
Processing of bauxite for smelter grade alumina is quite sensitive to bauxite recovery and total cost for processing of ore, particularly in wet beneficiation. On the other hand, owing to homogeneous nature and consistent quality, some alumina refineries prefer washed ore compared to simple crushed run-of-mine (ROM) bauxite.

Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and flushed away.

Bauxite can be divided into high alkali bauxite, high titanium bauxite and high iron bauxite according to its impurities. The process of separating bauxite concentrate from bauxite ore is actually a process of removing gangue minerals and harmful impurities, separating high aluminum minerals and low aluminum minerals, so as to obtain a concentrate with high
