EXPLANATION OF THE FROTH FLOTATION PROCESS IN DETAIL The main principle of the froth flotation process depends on the differences in the wetting properties of the sulfide ore and the impurities (which may or may not be non-sulfide ores). Figure 1: Froth flotation cell[4] The components of a flotation system are (figure 1):
