Chemical Process Of Bauxite Mining

2008-9-29 · The first step in the commercial production of aluminum is the separation of aluminum oxide from the iron oxide in bauxite. This is accomplished using a technique developed by Karl Joseph Bayer, an Austrian chemist, in 1888. In the Bayer process, bauxite is mixed with caustic soda, or sodium hydroxide, and heated under pressure. The sodium

    2019-4-26 · 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.
