Fine and/or light hydrophilic particles may pass upwards through the collection zone by entrainment. There are two forms of entrainment. In the first, a portion of feed water containing suspended fine particles passes into the froth. This type of entrain-ment can be minimized by maintaining a net downward flow of water through the upper column zones. The second form of entrainment is the capture of particles in the eddies behind a rising bubble. These particles are also rejected in the froth zone operating with positive bias.
