Bauxite, which consists of oxide type ores containing hydrated alumina is mainly used for the production of aluminum. In addition, minor amounts of bauxite and alumina are consumed in the refractory, abrasive and chemical industries.
Aluminum is obtained from two basic sources:
| Capacity | According to buyer |
| Production Process | Design for buyer |
| Equipment | Produce and install |
| OEM | ACCEPT |
| Funcations | Negociated |
The actual beneficiation processes adopted are deter-mined by the nature and physical properties of ores and gangue minerals,their mde of association with each otherthe method of exploiting the deposit and the end.use of thebeneficiated product,In small-scale mining operat ions,selective mining is supplemented by hand sorting wherebyferruginous or siliceous impurities like laterite, quartz,etc,are separated from bauxite with the help of megascopiccharacteristics like colour,texture, specific gravity, etc.In large-scale mechanised mining, the upgradation of r o,m.ore by simple manual dressing,sorting,screening and washingis not practicable,In such cases,mechanical beneficiationof the r,o,m,bauxite becomes inevitable particularly whenthe ore bly is mixed up with deleterious constituents. Themechan ical benefic iation methods for upgrading such bauxitecan only be effective if the impurities are easily liberatedfrom the ore by comminution.Metallurgical grade bauxitesare beneficiated by mechanical screening and washing.
The beneficiation techniques that are employed in China and some important bauxite producing countries are not effe~ctive in beneficiating marginal or sub.marginal grade ores inwhich iron,kaolinitic clay and titanjum minerals are finelydispersed in the crystal lattice of bauxite minerals, Althoughconsiderable research has been and is being carried out invarious countries to develop method for beneficiating suchores,none of the physical or chemical processes tried so faron a laboratory.scale has been found to be commercially fiable.
