Flotation Differential Sedimentation

Flotation Froth flotation (or simply flotation) is a physico-chemical separation process that utilises the effect that different materials normally show also differences in surface properties (e.g. surface tension), for separating a mixture of materials into its fractions. This difference in surface properties yields in a different tendency of
