  • Heavy Liquid Separation Purdue University

    Heavy Liquid Separation This step is the most important in the mineral separtion lab procedure Heavy mineral separation removes all the minerals that are more or less dense than quartz Minerals such as rutile (TiO2) and zircon (ZrSiO4) and coal will disrupt later chemistry Procedure Materials: 250 ml separatory funnels Ring standsIn the mineral industry, heavy liquids are commonly used in the laboratory to separate the “light” minerals such as quartz and clay from the “heavy” minerals The density used for this type of separation is about 285 g/mL, nearly three times theLST Heavy liquid for density separations ChemHeavy Liquid Separation Mineral Separation Lab The photo above shows the basic set up for heavy liquid separation, including the separatory funnels on the ring stands with the coffee filters below The funnels are correctly labled and also contain the sample withHeavy Liquid Separation Purdue University: Department
