Beneficiation and agglomeration process to utilize low-grade
Hence, theoretically, iron can be reduced to 5% without considering the iron dissemination in finer size ranges. In the size analysis, it was found that gangue minerals are concentrated in finer fractions and classification at 0.50 mm size can remove 44% alumina; 38% silica and 27% iron at 15% manganese loss.

Effect of Bauxite Microstructure on Beneficiation and Processing
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.
