Aug 02, 2017 · From Geo-metallurgical point of view, the bauxite mines of the world can be divided in 3 groups namely Gibbsitic Bauxite (less than 3% monohydrates), Boehmitic and Diasporic Bauxite. The earlier definition of Gibbsitic bauxite with less than 5% is modified here as low temperature alumina refineries prefer low boehmite as it causes auto-precipitation apart from non-recoverable alumina.
