WEB6 days ago · Bayer's process will be uneconomical due to generation of insoluble sodium aluminium silie. Aluminium ore is also called bauxite. The bauxite is purified to produce aluminium oxide, which is a white powder and aluminium can be extracted from it. The extraction is done by the process of electrolysis. Note: Red Mud is the waste product .
