Magnetic Separation of Gemstones

2009-6-25  Magnetic Separation of Gemstones Sylvia Gumpesberger Toronto, Canada INTRODUCTION Some gems are more magnetic than others, making magnetic separation of gem materials possible. Historically, this approach was hindered by the lack of strength of then available magnets, such as aluminum nickel cobalt (“Alnico”).

Induced Magnetic Roll Separator IMR Bunting Redditch

2021-5-17  The Induced Magnetic Roll Separator (IMR) uses an electromagnet to generate high-intensity magnetic fields. These magnetic fields enable the separation of weakly and para magnetic minerals (e.g. mica, iron-coated silica, etc) from non-metallic minerals (e.g. feldspar, silica sand, zircon, etc) in a dry state.

Eriez Dynamic Drum Separators

The non-magnetic fine powder does not react with the magnetic field and falls away from the head pulley in a normal trajectory. A strategically placed splitter enables separation of the iron from the non magnetic powder. The success of the DDS is attributed to the unique Eriez Dynamic Agitation Effect. This greatly improves magnetics recovery

Spearating Look-alike Gems gemstonemagnetism

Separating look-alike gems with a magnet. Chrome Tourmaline and Verdelite Tourmaline can look similar, but Chrome Tourmaline (a Dravite species) is rarer and more valuable. The two are easily separated with a magnet. The deep green color of Chrome Tourmaline is due to small amounts of chromium and/or vanadium, and it is usually inert (diamagnetic) when floated, or occasionally very
