Theory and Applications of the Jameson Cell

The Jameson Cell is a new form of flotation machine whose principles of operation are rather different to existing technologies. The feed plunges down a downcomer in the form of a jet. Air is drawn in from the atmosphere, and forms a dense froth with the feed in the downcomer. The
plunging jet creates a very favourable environment for the creation of very small bubbles, and for bringing them into contact with the particles in the feed. Thus high recove-ries can be achieved with very small residence times, of the order of 10 seconds in the downcomer.
