Bauxite Beneficiation: An Approach to Value Addition in ...

2021-7-2  The most effective way to remove both kaolinite and goethite is by washing, followed by attrition scrubbing and desliming through removal of clay-rich super fines in hydro-cyclone. Processing of bauxite for smelter grade alumina is quite sensitive to bauxite recovery and total cost for processing of ore, particularly in wet beneficiation.

Kaolinite removal from bauxite by flotation

One of the objectives in bauxite beneficiation is to reduce the content of aluminosilicates. The presence of aluminosilicates, such as kaolinite, illite and pyrophyllite, decreases the alumina/silica mass ratio, and, consequently renders unfeasible the utilization of the bauxite in the Bayer Process to produce alumina.
