The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide
Insoluble components of the bauxite are removed by digesting the ore with very hot caustic soda (sodium hydroxide) in the Bayer process. A waste by product of the Bayer process for producing al oxide from the bauxite ore, red mud contains toxic heavy metals and its high alkalinity makes it extremely corrosive and damaging to soil and life forms, presenting a massive problem for disposal.

Red mud, formally termed bauxite residue, is an industrial waste generated during the processing of bauxite into alumina using the Bayer process. It is composed of various oxide compounds, including the iron oxides which give its red colour. Over 95% of the alumina produced globally is through the Bayer process; for every tonne of alumina

In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch. However, some lateritic bauxite ores are readily soluble in caustic, making it possible for them to be leached, or “digested,” at atmospheric pressure.

Optimal bauxite blends with constant composition secure optimal use of caustic soda and other reagents during refining and avoid costly processing of waste material. Control of the moisture content on the conveyor belt using near-infrared (NIR) technology, together with accurate monitoring of the composition of iron ore before shipment, guaranties constant ore quality to avoids penalties.

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.

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.
