Gravity and heavy medium separation GTK

Gravity and heavy medium separation methods are used when separating minerals with different specific gravities. Typical examples of such industrial minerals include chromite and kimberlite. The method is also used in precious metal and sulphide ore combination processes and in a variety of recycling processes as an auxiliary method.

Flotation of chromite and serpentine - ScienceDirect

Jun 15, 2007  FSA seems to be an effective medium for selective separation of chromite from serpentine. At pH values 6–10 the flotation recoveries differ by around 65% and chromite floated almost quantitatively. The best conditions for selective separation of chromite from chromite–serpentine mixture were achieved at pH 8.0 using 20–30 mg L −1 ...

Improving the Quality of Ferruginous Chromite Concentrates ...

The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron ratio.

Separation is facilitated by a separation medium as follows; for densities greater than 2.96g/cm³, an unstable suspension of TetraBromoEthane (TBE) and atomised ferrosilicon is used as the medium. This method of fractionation is time-dependant and hence only particles coarser than 1mm can be treated.
