A review of froth flotation control
Re-circulating material through a flotation plant results in decreased residence time of material per flotation cell, but does allow for the valuable material to spend more time in the flotation plant as a whole; and, subsequently, increases the overall recovery (Wills and Napier-Munn, 2006).
