A packing-flotation column was proposed to optimize the flotation environment A research system was established using a 100 mm diameter cyclonic micro-bubble flotation column to study fluid properties. Dry-plate and wet- plate pressure drops were studied and the corresponding pressure drop equations developed. The results show that the dry-plate pressure drop of the packing cyclonic micro-bubble flotation column is 10-15 times less than that of the chemical tower, which is principally shown in its relatively small resistance coefficient, 0.0207. The wet-plate pressure drop is 2-3 times higher than that of the chemical tower, which is largely caused by the separation materials and characteristics of the equipment. With flotation, the greater the pressure drop, the better the flotation environment.
