chrome from ug2 tailings by falcon process

The impact of platinum production from UG2 ore on

quantities of chromite with typically a chrome-to-iron (Cr/Fe) ratio of 1.35. UG2 ores can contain between 10 and 25% Cr2O3 depending upon the reef width and the selected mining method. It is relatively cheap and easy to extract a portion of the chromite from a platinum concentrator tailings stream at a grade of between 40–42% Cr2O3.

PGM Ore Processing at Impala's UG-2 Concentrator

Historically UG2 ore could not be processed due to the high chrome content in the feed and subsequently in the final concentrate. Very little of the chrome itself exhibits any degree of positive floatability, but when excessive grinding takes place it reports to the final concentrate in the form of entrainment. The chrome occurs in the ore as a

Therefore the Cr2O3, PGEs and Au mineralisation that is now being targeted in the tailings, originates from within the UG2 chromitite seam itself. Some of the tailings were later reprocessed at Barplats to extract a limited amount of the Cr2O3 (an estimated at 1%-2% was processed) and PGEs (estimated at a grade of 0.2 g/t) and then re-deposited in the new front compartment of the tailings dam
