Frantz isodynamic separator

Many other devices are available for laboratory use. These include the Davis tube, Frantz isodynamic separator, laboratory dmm-type separators, low intensity rotating field separator, and superconducting high gradient separator (2). 

The Cryostream operates with a peak field of 4 tesla and a magnetic force of 250 XVm allows separation of minerals with magnetic susceptibilities in the order of l(r emu/g. In essence the Cryostream is an industrial-scale version of the well known laboratory Frantz Isodynamic Separator. 

Flinter [1959] investigated the separation of some alluvial minerals in Malaya, using the Frantz isodynamic separator with a constant forward slope of 15° and side slopes of 10°, 20°, and 30°. He found the following relationship ... 

Mafic minerals contained in volcanic rocks (phenocrysts) or in xenoliths are widely exploited in noble gas studies as they frequently contain fluid and/or melt inclusions that trap noble gases. Olivines and pyroxenes are the most commonly utilized minerals. Whole-rock samples are first crushed to 0.5 to 2 mm or larger, depending on the size of the crystals. The olivines and pyroxenes are then separated using a Frantz-Isodynamic magnet separator, followed by hand-picking under a binocular microscope to remove any...
