Bauxite is a mineral made up primarily of aluminium oxide mixed with some other minerals. Bauxite is regarded as high quality if it contains more than 50% of aluminium oxide. Bauxite supplies Confirmed global bauxite supplies are estimated at 18.6 billion tonnes. At the current level of extraction, this should last for more than a hundred years.

The aluminum production per year for a modern potline of 300 cells operating at 350 kA and 95% current efficiency is: The production of 1 ton of aluminum typically requires 420 kg of carbon, 1920 kg Al 2 O 3, and 16 kg AlF 3, and the specific energy consumption is 13.20 kWh/kg Al, as shown in Figure 2.5.11.

The bauxite is then transported to the crushing and washing area, reducing the particle size and increasing the available surface area for the digestion stage. The material that is discharged from the mill is called slurry; Digestion: The slurry is pumped to a digester where the chemical reaction to dissolve the alumina takes place. A hot ...

Bauxite ore is first mechanically pulverized and milled to reduce the particle size and then screened. The crushed ore is mixed with the process liquor containing caustic soda and processed in a grinding mill to produce a slurry containing 35–40% solids. Sodium hydroxide is the main chemical used in the process to extract aluminum hydrate ...

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. The ore is loaded into autoclaves and treated with lime–caustic soda.
