control and supervision of flotation cells
Supervision of Control Valves in Flotation Circuits Based. Flotation circuits play an important role in extracting valuable minerals from the ore. To control this process, the level is used to manipulate either the concentrate or the tailings grade. One of the key elements in controlling the level of a flotation cell is the control valve.

Level control strategies for flotation cells ScienceDirect
01/11/2003 Level control of flotation cells is a very complex task due to high interactions between the process variables. A control action implemented at any point in the flotation circuit tends to be transmitted to both upstream and downstream units, and sometimes with amplification. Large variations in the flow rate to the first cell and varying composition of the raw ore also cause problems
