Underflow Zone

The physical dimensions of this zone should be minimized since its roles are to ensure that there are no small bubbles entrained by the downward flow to the underflow stream, that sloughing of the solids particles does not occur, and that the outflow from the base of the column does not create unwanted flow patterns within the active zones of the vessel. Bubble entrainment to the underflow is obvious, as in this case frothing occurs in the tailing sump or in the next open tank downstream of the column.

A zone underneath the spargers does not contribute to the floatation collection or separation. Design con siderations of the zone include base cone angle and placement, underflow exit port configuration and height to spargers.
