  • Heavy Minerals Sands Processing by Rare Earth Magnets

    2020-6-25  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. The performance was not good because only a single separation pass flow sheet was used. Furthermore,
