Extraction Process of Aluminium from Bauxite Ore

Extraction Process of Aluminium from Bauxite Ore

 · 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 ...

However, some bauxites require some form of screening (either wet or dry) to remove the fine grained material to improve the grade and/or handleability. These deposits usually have a beneficiation plant that washes the bauxite and sends the high silica fines (kaolinite and/or quartz) to a tailings dam prior to ship loading the bauxite.
