The mineralogical analysis in the ore showed that the occurrence of chromite phases in the ore is very similar in all Middle group seam layers as indicated in Figure 3. The six end-member compositions that combine to form chromite are hercynite (FeAl 2 O 4), spinel (MgAl 2 O 4), Fe-chromite (FeCr 2 O 4), magnesiochromite (MgCr 2 O 4), magnetite ...
In the processing of PGMs, these include the widespread use of flow sheets which take into account multiple liberation/beneficiations and are referred to as MF (mill-float) 2 or MF3 flow sheets. Figure 1 shows a typical MF2 flowsheet. The advantages of such circuits are that they reduce the propensity of over-grinding.
