    Bauxite is the main source of the rare metal gallium. [17] 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. [18]

  4. Bauxite mining in the United States - Wikipedia

    en.wikipedia.org/wiki/Bauxite_mining_in_the...

    Bauxite forms by the weathering of aluminum-rich and silica-poor rocks in hot, humid, climates, at places with good drainage. Under the proper conditions, weathering disintegrates the aluminium silicate minerals, and dissolves and removes the silica, creating bauxite. The mined US bauxite deposits have all been in the southeastern United States.

  5. Bauxite mining in Australia - Wikipedia

    en.wikipedia.org/wiki/Bauxite_mining_in_Australia

    Bauxite is a raw material used primarily in the production of aluminium. The bauxite ore is refined into alumina before being smelted into aluminium. [3] Australia is known for its high-grade ore, especially in the Weipa and Gove deposits. [2] The quality of bauxite ore is determined by its available alumina (Al 2 O 3) content.
