• Gallium - Wikipedia

    This lack of independent deposits is due to gallium's geochemical behaviour, showing no strong enrichment in the processes relevant to the formation of most ore deposits. The United States Geological Survey (USGS) estimates that more than 1 million tons of gallium is contained in known reserves of bauxite and zinc ores.

  • Bauxite - Wikipedia

    Source of gallium. 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 ion-exchange resin.

    Gallium also is a liquid over a greater temperature range than any other element. Gallium is one of the few substances that expands as it freezes, making solid gallium less dense than liquid gallium (water is another substance that possesses this property). Gallium has a very high boiling point, making it useful for high temperature thermometers.
