Apr 15, 2018 Heavy Minerals Sands Processing by Rare Earth Magnets. The first known attempts to apply a REM roll separator to a heavy mineral sands application were made in South Africa and Western Australia in 1985. At that time, an ilmenite beneficiation process, which was normally achieved with cross-belt separators, was tested with a full-size machine

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 zircon, apatite, monazite, barite, and pyrite
