LEVEL CONTROL STRATEGIES FOR FLOTATION CELLS

One of most commonly controlled variables in a flotation cell is the slurry level. The level in the cell influences the concentration and yield of mineral and it is therefore important that the levels in the cells remain stable. Level control of flotation cells is a very complex task due to high interactions between the process variables.
