Kristy Duffy, a minerals processing engineer at Hatch, suggested that the new coarse flotation technologies might be useful in a pre-concentration stage to remove coarse gangue. The stages might run: coarse grind, pre-concentration flotation, grind, rougher flotation, regrind and cleaning flotation. Gorain agrees that it could potentially …

It is widely accepted that flotation is the most popular mineral processing method consuming the greatest amount of water in all the mineral processing plants, e.g., floating 1 t ore normally requires 3~7 t water. Therefore, the flotation process can be regarded as the most intensive water consumption section in a mineral processing circuit.
