3.2.1 Heavy media separation. Heavy media separation (or sink-and-float separation) is a part of the gravity separation process and uses heavy liquids in the separation operation. The primer liquids for density separation include bromoform (2.84 g/cm 3) and diiodomethane (3.31 g/cm 3), where heavy particles (heavier than the selected liquid) will sink while light materials float.
