A review of froth flotation control
If the cell air flowrates are not controlled individually, and air is fed to a group of cells, butterfly valves are often operated manually to adjust the flow to each cell. Lastly, Laurila et al. (2002) add that "flotation cells with self-aspirating aeration mechanisms often do not have automatic airflow control.
