pgm magnetic separation:

PRODUCTION AND USES OF PLATINUM GROUP METALS

a magnetic nickel-rich phase with enhanced phase growth containing the vast majority of the PGMs which, after crushing and milling, can be recovered by magnetic separation. Alternatively, the crushed and milled converted matte may be treated hydrometallurgically to remove the base metals. In either case, a PGM-rich concentrate is produced which becomes the feedstock for PGM separation and ...

A discussion of magnetic separation techniques for ...

Magnetic separation has long been used to upgrade and beneficiate a wide variety of industrial minerals. Advances in both wet and dry magnetic separators over the years has broadened their use, and questions are often raised about which separation technique or equipment type is most appropriate for a particular operation. This paper will provide a brief look at existing magnetic separation ...

Magnetic separation - Wikipedia

Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those that are magnetic. This technique is useful for not all, but few minerals such as Ferromagnetism/ ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic ...

The terminology is confused further by PGM being referred to as platinum group metals (which is strictly correct) but often leads to the abbreviation of PGM, which refers to the mineral and not the metal. The abbreviation, PM, should be avoided as this ...
