Mineral separation applying heavy liquids is a common method used for separating high density minerals (e.g. zircon, baddelyite, apatite, rutile, titanite, sulfides, Fe-oxides etc.) from minerals of lower density (e.g. quartz, feldspar, micas etc.). We regularly use the heavy liquids Bromoform (max. density of 2.8 g/cm3) and Dimethyleneiodid (DI; max. density of 3.325 g/cm3).
