The Reflux Classifier (RC) is a relatively new technology for the coal industry. The potential of this equipment for the treatment of iron ore was demonstrated in this paper, especially for the size range between 150 μm and 45 μm. The performances of the RC out of this size range need to be more specifically assessed.

The first crushing of the bauxite may often take place at the mine before transport to the alumina refinery if located nearby, or to the shipping port for export. At the refinery further crushing and/or washing may take place before the crushed bauxite is subjected to a grinding operation for final sizing before digestion.

The bauxite is purified by the Bayer Process. First the ore is mixed with a hot concentrated solution of sodium hydroxide. The N aOH will dissolve the oxides of aluminum and silicon but not other impurities such as iron oxides, which remains insoluble. The insoluble materials are removed by filtration.This method is called the chemical method.
