Bauxite refineries produce alumina aluminum oxide, which is used to create aluminum metal. Bauxite is also used to manufacture other industrial products, such as abrasives, cement and chemicals. There are two operating bauxite refineries in the United States, both of which are located in Louisiana. The most frequently-occurring radionuclides and their decay products decay products The atoms

Refining four tons of bauxite yields about two tons of alumina. A typical alumina plant, using the Bayer process, can produce 4,000 tons of alumina per day. The cost of alumina can vary widely, depending on the plant size and efficiency, on labour costs and overhead, and on the cost of bauxite.

Extraction Process of Aluminium from Bauxite Ore

Extraction Process of Aluminium from Bauxite Ore

Jan 19, 2021 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 ...
