Aluminium oxide (IUPAC name) or aluminum oxide (American English) is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3.It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxide.It is commonly called alumina and may also be called aloxide, aloxite, or alundum depending on particular forms or applications.
Alumina is Aluminum Oxide. It is a white granular material. The Bayer Process is the most economic means of obtaining alumina from bauxite. To turn bauxite into alumina, we grind the ore and mix it with lime and caustic soda, pump this mix into high-pressure containers, and heat it.
Alumina refining ; Our alumina refineries are located at Utkal, Renukoot, Muri and Belagavi. Alumina produced from these facilities is largely utilised for our internal operations to manufacture aluminium. Excess alumina beyond our internal requirements is sold to third parties both in the form of standard alumina and specialty alumina.
