aluminium industries and small bauxite deposits, accelerating their prospecting and research activities to consider itilising indigenous aluminium-bearing minerals for aluminium production. However, the US for example, still imports over 90 per cent of its bauxite. The situation with bauxite is not
small. The plant of the Norsk Aluminium Co. at Hoyangfaldene (Sagne) stopped because of lack of alumina. This company has ob- tainecl a concesssion to mine bauxite in Surinam, Dutch Guiana, which may remedy the raw-material situation. This company lost 1,336,000 kroner during the year.

WATER REQUIREMENTS OF THE ALUMINUM INDUSTRY By Howard L. Conklin ABSTRACT Aluminum is unique among metals in the way it is obtained from its ore. The first step is to produce alumina, a white powder that bears no resemblance to the bauxite from which
The Bayer process dissolves the aluminium component of bauxite ore in sodium hydroxide (caustic soda); removes impurities from the solution; and precipitates alumina tri hydrate, which is then calcined to aluminium oxide. A Bayer Process plant is principally a device for heating and cooling a large re circulating stream of caustic soda solution.
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to ...
The smelting of aluminum begins with the extraction of bauxite ore by a form of open cast mining. The bauxite is washed and screened before being converted to alumina, a white powdery element from which the aluminum is produced. Aluminum smelting is carried out in a Hall Heroult reduction cell, which is lined with carbon. A mix of alumina and cryolite is fed into the cell and carbon blocks ...

Aluminum Manufacturing Industry Description and Practices The production of aluminum begins with the mining and beneficiation of bauxite. At the mine (most of which are of the surface type) bauxite ore is removed to a crusher following which the crushed ore is screened and stockpiled ready for delivery to an alumina plant.

Bauxite mining requires relatively low energy inputs, compared to other steps in the aluminium production process – with less than 1.5 kilograms of fuel oil (mainly in the form of diesel for haul trucks) and less than 5 kWh of electricity consumed per tonne of bauxite extracted.
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.

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 (Al(OH) 3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH)) and small amounts of ...
The Bayer Process is the most economic means of obtaining alumina from bauxite. Other processes for obtaining alumina from metal ores are also in use in some refineries, particularly in China and Russia, although these make up a relatively small percentage of global production. The process stages are: 1. .
