Bauxite is a sedimentary rock mineral that is the primary source of aluminum. It is formed through the weathering of aluminum-rich rocks in tropical and subtropical regions. The name bauxite is derived from the French village of Les Baux, where it was first discovered in 1821 by geologist Pierre Berthier. Bauxite is typically found in layers …

Bauxite rock is mined and extracted through land clearing, digging, and removing thick sections of bauxite ore by means of blasting or ripping. Bauxite mining calls for the use of heavy equipment. Miners commonly use machines like bulldozers, scrapers, front-end loaders, and hydraulic excavators to help with the digging.
