Primary Aluminum Refining. Aluminum production from bauxite ore is a three step process. First the alumina is extracted from bauxite ore usually using the Bayer Process. In the Bayer Process, finely crushed bauxite is mixed with sodium hydroxide and placed in a `digester.''. High temperatures and pressures in the digester cause reactions in the

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.

Alumina Extraction Problem. 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

The process which gives the ore such a physical form so that the gauge can be easily removed from it, is called dressing of the ore. It is done by hand – picking, grinding etc. Bauxite ore generally contains ferric oxide and silica as impurities. Dressing of bauxite ore is done by crushing and pulverizing.
