separation techniques, froth flotation employs a relatively high gas flow-rate under turbulent conditions. Next to froth flotation, the most useful foam separation technique is precipitate flotation where the species to be separated is first precipitated, usually by a change of solution pH, and thenseparation techniques, froth flotation employs a relatively high gas flow-rate under turbulent conditions. Next to froth flotation, the most useful foam separation technique is precipitate flotation where the species to be separated is first precipitated, usually by a change of solution pH, and thenFlotation is a separation technique based on the capture of particles by bubbles and their collection in a froth layer.
