Process optimization of a chrome ore gravity concentration …
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).
Hydrocyclone Working Principle
The entrance to the cyclone was designed this way to allow the incoming feed to help generate and not interfere with the spiral path that the ore must take inside the cyclone. The centrifugal force (the central Hydrocyclone Working Principle) that is generated by this spin, forces the "bigger particles outwards towards the wall of the cyclone ...
A study on the recovery of fine chromite from UG2 tailings
Subsequent flotation tests at natural pH on hot tailings samples with two stages of cleaning showed good upgrading, where a feed grade of 16.1 % Cr 2 O 3 after desliming was converted to a concentrate of 29.4 % Cr 2 O 3 at a yield, based on deslimed feed, of 28.6 % and a recovery of 52.4 %. The overall upgrade ratio in this case of 1.83 was slightly lower than those …

ore (e.g. grade in the heavy products) are not always considered for preconcentration. Compared to the cyclone which is limited by the crowding effect in the apex, the multi-stage separation in the Condor unit provides larger sinks product capacity. The primary advantages of using a dense medium cyclone arise when only a single stage
THE DEVELOPMENT OF THE VOSKHOD CHROME …
lower grade ore (at less than 2.97t/m3 ) should ensure very good separation in the DMS drum and DMS cyclone stages resulting in high recoveries of Cr2O3 - rich chromite ore products. Very high chrome ore grades of up to 64% Cr2O3 and Cr/Fe ratios of 4 to 1 were obtained at an 80% mass yield from selected samples of lumpy and chip ore size ...

Hydrocyclone
The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container. The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds of times greater …
