Lime use and functionality in sulphide mineral flotation ...

Nov 01, 2019· In a flotation plant, lime can be used to control the pulp pH and NaSH/SO 2 to regulate the Eh in the proper range for selective flotation to occur. From a practical point of view, however, it is difficult to maintain the pH/Eh at the specified range in flotation if air is used as the carrier.Cited by: 16

A direct flotation tends to take almost all of your impurities into froth just by entrainment. A separation is possible if you have a very dilute slurry, but this is commercially not viable. At the very high solid contents used in commercial limestone float operations, a direct flotation would result in mass transfer of all impurities as well into froth, just by mechanical entrainment.
