bauxite mineral performance

Bauxite - an overview | ScienceDirect Topics

Bauxite. Bauxite contains typically 40–60% aluminium oxide (alumina) in the form of several hydrous alumina phases (gibbsite, Al (OH)3, boehmite (AlOOH) and diaspore (ALOOH), and with smaller amounts of iron, silicon and titanium compounds as well as other trace impurities. From: Fundamentals of Aluminium Metallurgy, 2011.

What minerals are in bauxite? – JanetPanic

2018-10-15 · What minerals are in bauxite? The principal minerals in bauxite are gibbsite (Al2O3. 3H2O), boehmite (Al2O3. H2O) and diaspore, which has the same composition as boehmite, but is denser and harder. Australia is the world’s largest producer of bauxite, representing 28% of global production in 2012.
