In the Bayer process, the insoluble residue obtained after digestion of bauxite with sodium hydroxide at elevated temperature and pressure to extract alumina is known as red mud, or bauxite residue. Annual production of smelter and chemical grade alumina in 2015 was about 115 million tonnes produced using the Bayer process.

Serpeck's process Bayer's method and Hall's method is used for the red bauxite which contains F e 2 O 3 and silicates as impurities. Serpeck's method is used for the white bauxite which containes silica as impurities.
Serpeck's process. The purification process of aluminium is based on the amphoteric nature of aluminium oxides. Since aluminium is found in compounds with other elements it needs to be reduced. The Bayer process is essentially referring to the refining of bauxite, the most important aluminium ore, to produce alumina. ...
Keeping the above characteristics in view, several west coast lateritic bauxite mines of India employ dry crushing−screening process to bring down silica content from the metallurgical grade bauxite [].Recently, a bauxite mine of Guinea known as AGB2A has also adopted the dry beneficiation procedure to cut down silica from about 7% to below 3%, to make this one the best metallurgical grade ...
Bauxite is Al 2O 2O. Water molecules and other impurities are removed from it to make it pure Al 2O 3. By leaching in the Bayer's process, pure Al 2O 3 obtains. When a sulphide ore is roasted, it turns to oxide ore. Here the ore is oxidized and the ore acts as reducing agent. So sulphate part acts as reducing agent.
