Since the middling slurry in the flotation process varies frequently and its maximum variation can be over 60% of the concentrate slurry of the magnetic separation process, the flow-rate of the underflow slurry might exceed its target range. This often leads to the flowrate and its rate of changes exceeding their target ranges.
