Heavy Liquids Separation. The final step in mineral separation is by preferential flotation of mineral fractions by heavy liquid. Nonmagnetic fractions first undergo separation by sodium polytungstate (SPT; 2.85 g/cm3) and finally by methylene iodide (MEI; 3.3 g/cm3). At the end of separation, the final fraction should contain minerals such as ...

LST Heavy liquid for density separations

In 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 2.85 g/mL, nearly three times the density of water.

Mar 24, 2021  Three different types of heavy liquids and a magnetic separator (Frantz) can be found in the mineral separation room. This room is mostly used for separating heavy minerals - like zircon, monazite and apatite - from lighter minerals. Zircon and monazite are important minerals for U/Pb dating with the help of laser ablation and a mass spectrometer.
