The Effect of Hydrodynamic Conditions on the Selective Flotation of Fully Liberated Low Grade Copper-Nickel Ore

Low grade sulfide ores are difficult to process due their composite mineralogy and fine grained dissemination with gangue minerals. Therefore, grinding of such becomes essential liberate valuable In this research, selective flotation was carried out using two pitched blade turbine impellers diameters 6 cm 7 float copper nickel. The main focus research generate optimum hydrodynamic conditions that can effectively separate nickel from addition, we investigated the effects superficial gas velocity, impeller speed, bubble size distribution, surface area flux on recovery rate constant. results demonstrated a comparatively produced improved Cu-Ni maximum recoveries in tests were observed at 93.1% 72.5%, respectively. However, significant decrease observed, entrainment concentrate slime coating minerals particle surfaces.
