Among the influencing factors shown in Fig. 1, particle size is the most important [[9], [10], [11]].Froth flotation works best when minerals are in an intermediate particle size range, typically from 20 to 150 μm, but varies with the types of minerals [[10], [11], [12]].When particles are smaller than about 20 μm, value mineral recovery and separation selectivity drop quickly.
