An optimization routine for a flotation circuit must first begin with mastering level control even in the presence of disruptions (waves, etc). Ideally, a level control system would adjust downstream levels preemptively to account any upstream disruptions before the effects of the disruptions propagate downstream. The level for each cell is a ...
