At present, the use of mechanical flotation cells of up to 300 m 3 has become common in the mining industry, and more recently cells of up to 660 m 3 have been tested and incorporated in industrial operations (Lelinski et al., 2017, Romero, 2018). Due to their greater size, fewer cells are now necessary for larger flotation capacities.
