Bauxite Wikipedia

Bauxite is the main source of the rare metal gallium. During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ionexchange resin. Achievable extraction efficiencies critically depend on the original

Lateritic Bauxite Deposits – Our Largest Source of

Selective mining ensures that only the highest grades are mined. Below the pisolitic bauxite horizon is a nodular ironstone layer. At this level, the bauxite becomes increasingly iron and kaolinrich. Kaolinite, which contains a great deal of silica, is also much lower in aluminium content than bauxite.
