processing bauxite

Mining and Refining – Process

The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.

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.
