What is Bauxite? Mineral, Formula, Uses with Videos and FAQs BYJU'S

Bauxite is an aluminiumrich ore used for the manufacture of aluminium (metallurgical bauxite) and refractory products, chemicals or cements. Bauxite is a prime important raw material for the primary aluminium industry. It is also used in a number of nonmetallurgical sectors, like refractory, abrasive, cement, steel making and chemicals.
