The mined graphite ore contains several gangue materials which needs to be removed through beneficiation. Ore beneficiation is a separation technique that enriches the desired mineral from their ores through systematic judicious removal of gangue materials that are undesirable.
The flotation experiments were performed by varying the flotation cell energy input parameters of volumetric air input flow rate and flotation cell rotor speed depending upon the experiment matrix. Level in the flotation cell was maintained using a 20-liter conditioning tank. Frother and pH modifiers were added into the conditioning tank.
The results showed that the performance of the combined flotation process of the cyclonic-static microbubble flotation column (FCSMC) and mechanical flotation cells was superior to that of the mechanical flotation cell, while the flowsheet was simplified.
