iron bauxite mining process

  • 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 resinAchievable extraction efficiencies critically depend on the original concentration in the feed bauxiteBayer process Bauxite ore is a mixture of hydrated aluminium oxides and compounds of other elements such as iron In the Bayer process, bauxite ore is heated in a pressure vessel along with a sodium hydroxide solution (caustic soda) at a temperature of 150 to 200 176;C.
