Bauxite | The Aluminum Association

Metallurgical Bauxite: The metallurgical Bauxite is used for aluminium production. Metallurgical bauxites are sub-divided into two basic types based on the processing methods that must be applied to them at the alumina refinery stage, namely: (i) low temperature gibbsite (tri-hydrate or tropical bauxite) & (ii) high-temperature boehmite (monohydrate or European bauxite).30 BAUXITE AND ALUMINA - USGS,BAUXITE AND ALUMINA1 (Data in thousand metric dry tons unless otherwise noted) Domestic Production and Use: In 2019, the quantity of bauxite consumed was estimated to be 5.1 million tons, 30% more than that reported in 2018, with an estimated value of about $162 million.
