Overview of Known Alkaliphilic Bacteria from Bauxite Residue
Bauxite residue, also known as red mud, is an insoluble byproduct generated from the extraction of alumina from bauxite during the Bayer process (Figure 1), a crucial step in manufacturing aluminum. Solid waste residue is generated from the digestion of bauxite ores with caustic soda for alumina (Al 2 O 3) production [11].
Bauxite
Bauxite is the most common aluminum ore. Approximately 98% of primary aluminum production is based on bauxite. In the former Soviet Union, aluinite and kaolinite are also used in small proportions for aluminum production. Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals plus ...
