Flotation is the principal process for preconcentration of the sulphides for subsequent smelting roasting or hydrometallurgical treatment However the selective separation of chalcopyrite and pyrite minerals by froth flotation is often problematic due largely to the number of minerals involved and the nature of the associations of theseOre Concentration by Froth Flotation and a collector chemical called potassium amyl xanthate (or the potassium salt of an alkyl dithiocarbonate) The waste material that comes out of the bottom of the tanks at the tail end of this process is called tailings It is nothing than ground up rock with the copper minerals removed

During the flotation process frothers help create the ideal hydrodynamic conditions (such as bubble size and gas holdup) required within the pulp in the flotation cell They generate froth that is stable enough to hold collected minerals on top of the pulp mobile enough for removal and decays quickly to assist with downstream operationsThe process flowsheet for the two stage circuit is shown in Figure 8 A Microcell™ flotation column froth product after derating was sent to a multi gravity separator (MGS) developed by the Mosley Ltd UK The MGS is similar to the shaking table except that the particles in the flowing film are also subjected to centrifugal forces
