beneficiation of bauxite ore

Beneficiation of bauxite - [email protected]

Beneficiation of bauxite containing less than 4-5% silica was not found to be justifiable especially in view of the depletion of ore reserves. A typical economic analysis for bauxite containing 4'43°, reactive silica is summarised in Table Ill. A proposed scheme for beneficiation by dry screening A schematic flow diagram for the proposed beneficia-tion plant is given in Fig. No. 1. In the ...

Mining and Refining – Process - World Aluminium

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which include washing, wet screening and mechanical or manual sorting. Beneficiating ore also reduces the amount of material that needs to ...

The microstructure of bauxite determines to a significant extent the opportunities for its beneficiation and optimum processing downstream. Adequate fine grinding commensurate with its microstructure may result in proper mineral liberation and grain size distribution required for effective ore dressing (i.e. H/M or magnetic separation) and digestion respectively. Particle size distribution ...
