Effect of Bauxite Microstructure on Beneficiation and

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.

2 天前  Beneficiation and mineral processing of bauxite and feldspar. Bauxite is a sedimentary rock that is rich in alumina, the base for making aluminum. It is generally easy to mine because it is found near the surface of terrain. However, the process for separating the alumina from the other base elements in bauxite can be environmentally unfriendly.
