Concentration of bauxite fines via froth flotation SciELO Rem Revista Escola de Minas Although froth flotation of silicates is well known and mostly applied for mineral concentration, the use in bauxite ,
Gibbsite-rich bauxite is preferred as it can be refined at lower digestion temperatures than the other types of alumina bearing minerals; Bauxite is usually reddish-brown, but can also be white, tan, and yellow, depending on the type and concentration of iron minerals present
What is Bauxite? Many people are surprised to learn that bauxite is not a mineralIt is a rock composed mainly of aluminum-bearing minerals It forms when laterite soils are severely leached of silica and other soluble materials in a wet tropical or subtropical climate
The use of the gravity concentration process, including classification in cyclones, and magnetic separation proved to be feasible for the bauxite from CBA's operations Plant production and available alumina increased as a result of their application
Although froth flotation of silicates is well known and mostly applied for mineral concentration, the use in bauxite in not usual Therefore, this is a pioneer, innovative process for bauxite concentration,
So bauxite is group of hydrated aluminum oxides, Al(OH)3 with possible additional Al and (OH) so it can be written as Al2O3nH2O where n represents that it can have different number of water molecules per Alumina based on concentration of mineral in the ore on an average
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
Bayer Today the Bayer process dominates the production of alumina as it is the lowest cost production route The process uses a recirculating volume of concentrated caustic solution to dissolve the alumina minerals, separate them from still solid impurities, and then re-precipitate alumina tri-hydrate
