Nonetheless, the grade of platinum in the chrome dumps compares very favourably with the 0.7 g/t to 1 g/t of the traditional platinum dumps. It is because chromite sources such as the chromite-containing LG-6 reef are typically not mined for PGMs, which are discarded along with tailings.
Rutile occurs as a minor phase in association with PGM, included in chromite or in the contact chromite–silicate. The mode of occurrence of rutile in the Nuasahi chromitite is similar to that reported from the stratiform chromitites emplaced in stable cratonic settings.
