The separation of the heavy minerals from the silt fraction is performed according to the following procedure. 1. An 82. 75-mass percent solution of SPT in water (827 .5 g SPT in 172.5 g water equals 1,000 g solution) is needed to create a solution with the desired density of 2.85 g/cm3. Other densities (1.0-3.1) can easily be

Heavy-media separation | Britannica

Other articles where Heavy-media separation is discussed: mineral processing: Gravity separation: In heavy-media separation (also called sink-and-float separation), the medium used is a suspension in water of a finely ground heavy mineral (such as magnetite or arsenopyrite) or technical product (such as ferrosilicon). Such a suspension can simulate a fluid with a higher density than water.
