Several attempts have been made by different researchers and technologists to understand the separation behavior of particles in each of these separators treating different types of para-magnetic minerals. Despite all these efforts, these separators are yet to find widespread applications to treat different para-magnetic …
A commonly used magnetic separation equipment for chromite ore beneficiation is a drum magnetic separator. This type of equipment uses a rotating drum surrounded by a magnetic field to separate magnetic particles from non-magnetic particles. Chromite ore is fed into the drum. As the drum rotates, magnetic materials …

The magnetic carrier tests performed in the case of individual minerals (i.e. single minerals) showed that chromite (recovery of 95.1%) could be separated from serpentine (recovery of 3.2% ...
To address this, dry magnetic separation is an alternative approach to separate these iron bearing gangue minerals from the chromite.This work investigated on the application of different dry high ...
As reported by Tripathy et al. [4] that the Cr/Fe ratio can be improved from 2.31 to 3.35 by gravity separation process using wet shaking table followed by high-intensity magnetic separation.
Chromite recovery from UG2 tailings by physical separation and flotation was studied. • Desliming, magnetic separation and acidic flotation (pH2.5) achieved …
Therefore, concentration of chromite is required. The most commonly used beneficiation methods for chromite ores are gravity separation, such as shaking table, jig, spiral, and Reichert cone ...
Magnetic separation of chromite can be differentiated based on the ore type, i.e., magnesian chromite or ferrian type chromite. As the chromite ore is of magnesian chromite, magnetic separation is ...
This paper investigates the potential for using dry magnetic separation to reduce the chromium content of a dried high quality olivine sand product in order to meet with anticipated future quality demands. The original feed contained 0.28-0.29% Cr2O3 of which approximately one third occurred as chromite and two thirds as chlorite. Two …

In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron ratio. Also, detailed characterization …
Chromite, Magnetic Separation, Paramagnetic, Tailing Recovery 1. Introduction Chromite is the major commercial source of chromium metal; this mineral is a
Chromite (FeCr 2 O 4) is the only commercially recoverable source of Cr. South Africa holds approximately three-quarters of the world's viable chromite reserves. Kazakhstan, India, Russia, Turkey, Finland, and Iran follow this country. ... gravity and magnetic separation wet methods were applied because the flue dust sample contains …
A petrographic examination was conducted on the minus 100-mesh magnetic separation products to characterize the products and to determine if further grinding would improve liberation of the chromite. The nonmagnetic fraction of the cleaner concentrate consists of approximately 73 to 75 pct chromite, 15-17 pct silicates, and 8 to 10 pct ...
To address this, dry magnetic separation is an alternative approach to separate these iron bearing gangue minerals from the chromite.This work investigated on the application of different dry high ...
