For mineral applications, mechanical flotation cells are now available with volumetric capacities up to ~120 m 3. For coal applications, however, where much of the flotation feed is removed as froth concentrate, the maximum practical size is considered closer to ~40 m 3 /cell. Fig. 1.6 shows a typical bank of mechanical flotation cells.
