Beschreibung
Zusammenfassung:	21 A process is disclosed which is capable of improving selectivity and recovery in subsequent mineral processing by flotation of fine sulphidic minerals of copper, lead, zinc, nickel, molybdenum, gold, silver, and the platinum group minerals. The process comprises: providing a high shear conditioner consisting of a pulp holding tank, a high shear impeller, and a motor and drive capable of providing power draw for the impeller in the 5 to 150 kW/m3 range; and imparting to the pulp a high energy input ranging from 1 to 100 kWh/m3 of pulp, depending on the volume of the tank.
