Metallurgical bauxite is a low-value bulk ore, and therefore preference is often given to simple beneficiation techniques, such as crushing followed by dry screening or washing and scrubbing processes. The most effective way to remove both kaolinite and goethite is by washing, followed by attrition scrubbing and desliming through removal of ...
