Origin of the UG2 chromitite layer, Bushveld Complex ...

Thus, the UG2 is the second layer up-section within the upper group. Except for the UG1, the Upper Critical Zone chromitites are generally embedded in pyroxenite (locally they are underlain by anorthosite). The one that hosts the UG2 is ≈25 m thick and is hereafter referred to as the UG2 pyroxenite. Fig. 2.

Determining the PGM bearing mineral phase in the UG2 ore ...

Jun 15, 2017· UG2 is a low grade PGM ore, with value concentration in the range of 1–2 ppm. In this paper, we aim to determine whether the PGM values in the UG2 ore are associated with a soft or hard mineral phase. The anticipated benefits of determining which mineral phase the PGMs are associated with is that such knowledge may be very useful in the ...
