The dry magnetic separator is used for sorting dry magnetic minerals, and is mainly used for selecting large-sized, coarse-grained ferromagnetic ores and fine-grained weak magnetic ores. It has three types of single disc (diameter φ = 900 mm), double disc (φ = 576 mm) and three discs (φ = 600 mm). The magnetic field strength can reach 880-1440 kA/m.
Chromite concentrates were as high as 55 pct Cr2O3 with a Cr-Fe ratio >2. Recirculating loads between the table and the Bartles-Mozley separator were 250 pct, which was predicted by the locked cycle test. Sand tailings from the Bartles-Mozley assayed between 2.9 and 3.3 pct Cr2O3, which was better than the bench tests.
Mozley multi-gravity separator (MGS) can be used with success for reducing fine chromite losses Large amounts of fine sized chromite tailings naturally occur in the gravity tailings of Turkish chromite gravity plants, based during production and processing, and this causes severe environ- on the fact that 105 lm fraction amounts to 8–46.4% of ...
Alongside models that rely on electricity to separate minerals, there are also physical separators. These aluminum oxide separator types include vibrating shaker tables and alluvial washing machines, and they can be used alongside more precise separation tools to prepare raw materials. But they can also be used alone when there's less need for …
Chromite typically sells for about 25-30% less than Zircon (comparing bulk prices of both types of sand). Chromite sand is black in color. So when you buy "heavy sand," make sure you are getting what you pay for. 1.00 pound of Chromite displaces 152cc vs. 295cc for Play Sand. So, that means Chromite is 94% heavier than an equal volume of Play Sand.

Our test facility delivers extensive testwork for chromite ores including: ROM and tails of LG, MG, and UG2. Materials from >15% Cr2O3 grade.
The wet magnetic separator has a wide particle size and a lower particle size of 20um. Therefore, the wet magnetic separator is more suitable when the zircon particle size is fine. Because there are many associated minerals in zircon sand, it is necessary to combine gravity separation, magnetic separation, flotation, and electrostatic …
