UNDERSTANDING FROTH BEHAVIOUR WITH CFD

2006-11-28 · flotation tanks have a volume of 100m 3 to 300m 3, and plants have 3 or 4 flotation stages, each with 6 to 10 tanks. Although occupying less than 10% of the flotation cell volume, the froth behaviour largely determines the fractional and relative recoveries of the valuable and waste minerals from the pulp to the concentrate.
