Central Chemical Consulting developed a safe, improved heavy liquid for material separations. The resulting low viscosity, low toxicity water-based heavy liquid replaces the toxic organic liquids such as bromoform and tetrabromoethane. LST Heavy Liquid is used widely in the mineral sands industry and in many research and testing laboratories for geological separations based on density. Software was also developed which simulated gravity settling of various minerals in heavy liquids. LST Heavy Liquid is manufactured by Central Chemical Consulting and now exported for use in over 60 countries.
