Sub-grade chromite ore with Cr2O3 of about 38.5% of Sukinda region of India, can be upgraded to a marketable chrome concentrate of 53–54% Cr2O3 with a recovery of about 58–60% and tailing loss of around 14–16.39% of Cr2O3, by using wet shaking tables in the circuit (Banerjee et al., 2005).

2nd Stage Concentration Process: The concentrated ore from the chrome ore jig machine or spiral chute separator will go to the chrome ore shaking table concentration machine for final concentration, which can get high-grade chrome ore concentrate. Shaking table is a good concentration effect mining equipment for chrome ore processing plant.

The lower density particles tend to be washed over the riffles to the lower edge of the deck. Tabling was tested as a method of primary concentration for each of the chromite ore samples. Separations were made using a one-eighth scale Deister shaking table with a sand deck (fig. 7).

The XRD of concentrate (d) presents higher hematite peaks. The chemical composition by ICP-OES shows 3.5% Mg, 9% Ca, and 40.4% Fe. According to Abaka-Wood et al., the gravity separation using shaking table of iron oxide silicate tailing with 26.2% of Fe provides a concentrate fraction of 49.3% Fe. The Abaka-Wood study …

A three layer feed forward neural network (3:3–11–2:2) as shown in Fig. 2 has been developed for predicting the recovery and grade of the concentrate fraction of wet shaking table by using the three operating parameters like wash water flow rate (L/min), deck tilt Angle (degree), slurry feed rate (L/h) etc. The MLP architecture obtained has ...

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 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 …

Shaking table is one of separation equipment of gravity method used to increase concentrate based on difference of specific gravity. The optimum concentration result is influenced by several ...

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

From roughing and scavenging spiral groups, ~85% of chromite could be obtained prior to the shaking table concentration, and this led to a minimum increase of 20% in the total …

The shaking table was used to process 500 g of the tailing. Three different materials were obtained after the Separation process: Hematite concentrate, middling, and Gravity separation ...
