Bauxite

Bauxite is a mixture of aluminum-rich minerals, chiefly gibbsite, boehmite, and diaspore. It is the principal ore used to produce aluminum.

Bayer process: An industrial process that extracts alumina from bauxite using hot sodium hydroxide. It separates aluminum-bearing compounds from bauxite before metal production.
Gibbsite: An aluminum hydroxide mineral and a common aluminum-bearing component of bauxite. It is one of the chief minerals that give bauxite its aluminum content.
Aluminum: A lightweight, corrosion-resistant chemical element widely used in alloys, packaging, and construction. Most bauxite is mined to supply aluminum production.
Bauxite mining: The extraction of bauxite from surface or near-surface deposits. It supplies refineries but can remove vegetation and alter landscapes.
Alumina: Aluminum oxide, Al₂O₃, used as the feedstock for primary aluminum production. This refined oxide is the intermediate product made from bauxite.
Boehmite: An aluminum oxide hydroxide mineral found in some bauxites. Its abundance helps distinguish the mineral composition of bauxite deposits.
Refractory: A heat-resistant material used to line furnaces and other high-temperature equipment. Some bauxite is processed into refractory materials for high-temperature service.
Aluminum recycling: The recovery of aluminum scrap for reuse, requiring far less energy than primary production. Recycling reduces demand for newly mined bauxite and energy-intensive refining.
Hall–Héroult process: An electrolytic process that produces aluminum metal from dissolved alumina. It converts the alumina derived from bauxite into aluminum.
Diaspore: An aluminum oxide hydroxide mineral that occurs in some bauxites. It is another principal aluminum-bearing mineral in the ore.
