Approximately 90 percent of all bauxite mined is refined into alumina, which is ultimately smelted into aluminum. The remaining 10 percent is used in other applications, such as abrasives, refractories, and proppants in the recovery of crude oil.

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.
The equipment used meets best mining standards. The Run of Mine (ROM) annually is at an average of 1.2 million metric tonnes. The 1.2 million metric tonnes raw bauxite ore produced is loaded into 45 cubic metre haulage trucks and hauled via road to the Takoradi Port Facility, which is approximately 240km.

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 is the principal ore of alumina (Al 2 O 3 ), which is used to produce aluminum (Al). It is composed of hydrated aluminum oxides, hydrated aluminosilicates, iron oxides, hydrated iron oxides, titanium oxide, and silica. It contains mixtures of various minerals such as gibbsite, boehmite, hematite, goethite, Al-goethite, anatase, rutile ...

Sustainable Bauxite Mining Guidelines ii Executive summary . Bauxite, the primary ore used to make aluminium, is refined into alumina, which is then smelted into aluminium. Other uses of alumina include chemical grade applications. Bauxite demand has historically been met by a few large players in the market, which have operated large scale mines.
Sustainable bauxite mining is not a "one-size fits all" prescriptive process but involves risk management and applying technologies appropriate to the circumstances of each mine. These Guidelines build on the 2018 Sustainable Bauxite Mining Guidelines (SBMG) and provide a practical, attainable guide to improve sustainability.
