upgrade the low-grade chromite ore using different physi-cal beneficiation techniques for production of ferrochrome/ charge chrome. Gravity method like tabling was used by many workers to pre-concentrate chromite ore [6–19]. Nafziger [20] while reviewing the beneficiation of low-grade chromite ores from the world over opined that
Gravity concentration of Sudanese chromite ore using laboratory shaking table 273 ore at a feed size fraction +100 mesh (+150 μm) materials (Hunter and Sullivan, 1960). Considerable amount of coarse gangue minerals was rejected and a sink product assaying 35.0% Cr 2 O 3 at a recovery of 86% was obtained.

Supply of world chromite (chrome ore) has come under severe pressure over the past year driven by strong demand for ferrochrome used in ferroalloy production for making stainless steel.
These being the PCMZ_MG (medium-grade Ni-Cu sulphide silicate ore with disseminated chromite), PCMZ_HG (high-grade Ni-Cu sulphide silicate ore containing disseminated chromite) and MCHR (massive chromite unit) ore types. These were processed using benchtop flotation followed by gravity concentration using a shaking table at different …
Shaking tables are widely used in commercial mines but have found little use by small-scale miners due to their relatively high cost (Mitchell, C.J., 1997).They utilize both particle density and to a lesser extent particle size to fractionate ne ore samples (<1mm) into products, middlings and waste fractions (Mintek 2016). That is, if a

The investigation result of Güney et al. (2001) depicts that the chrome concentrate of 45%–48% Cr 2 O 3 and a tailing loss of below 7% Cr 2 O 3 with an overall plant recovery of 60%–65% can be recovered by introducing shaking table for 0.1–1.0 mm size fraction and high-intensity wet magnetic separator and column flotation for treating ...
Chrome has strong siderophilicity, and ferrochrome is often associated, also called chromite.Chrome ore beneficiation aims to extract chromium minerals from raw ore and remove impurities to obtain high-quality chrome concentrate. Generally speaking, chrome ore contains a certain amount of iron, so gravity separation and magnetic separation …
Chrome ore beneficiation. Most of the chrome ores around the world are beneficiated by gravity concentration techniques. A conventional chromite ore beneficiation process plant (Figure 3) consist of two sections: > Communition (for preparing the material for the subsequent unit operations) > Concentration (classification and beneficiation).

The aim of this study was to optimize the recovery of chromite from the chrome plant tailings of the South African Middle Group chromite seams using a shaking table. The optimization process employed the response surface methodology in conjunction with the central composite design. The independent variables considered in …
Particle shape characterization of shaking table streams in a Turkish chromite concentration plant by using dynamic imaging and microscopical techniques
Whilst the use of a shaking table was unsuccessful, a pilot Jones wet high intensity magnetic separator (WHIMS) proved to be more promising. In the latter case, testwork was conducted on an 'as-received' sample from the concentrator, i.e. that did not undergo any feed preparation, and another that was deslimed at 25 µm by wet …

The mainly process of chrome ore processing is gravity separation.Sometimes low intensity magnetic separation or high-intensity magnetic separation will be used to deal with the chrome concentrate for a second processing to improve the grade of the chrome. Also some ores treated by flotation, but the gravity separation is still the main processing way …
