  • 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 ion-exchange resin.Achievable extraction efficiencies critically depend on the original concentration in the feed bauxite.
