Influence of Froth Height on Column Flotation of ..
The influence of the froth height in the reverse flotation of kaolinitic ore was analyzed based on the recovery by entrainment and by true flotation of iron titanium and manganese oxides FeO TiO2 and MnO Also the influence of the particle size in the drainage process was analyzed The recovery by entrainment and by true flotation of the three oxides is inversely proportional to the froth
