Bauxite - AIMR 2013 - Australian Mines Atlas

The bauxite mines in the Darling Range have the worlds lowest grade bauxite mined on a commercial scale (around 27-30% Al 2 O 3). Despite the low grade, the mines accounted for 23% of global alumina production as they also have low reactive silica, making the bauxite relatively easy to refine.

The Chemistry and Processing of Jamaican Bauxite

In October, 1943, Alcan was incorporated under the name Jamaica Bauxites Limited as a Jamaican company to investigate the commercial potential of Jamaican bauxite. In the same year, 2500 tonnes of ore was shipped to the USA for process investigation and it was realised that the bauxite was suitable for processing using Bayer technology.
