concept of ore upgrading metals recovery and refining

Nov 13, 2015 Nov 13, 2015 • On UG2 ore specifically, ore upgrading will result in not only a higher PGM grade to the mill but an increase in chromite spinel concentration measured as % Cr 2O 3; as silicate waste is rejected. The benefit is an increase in chromite by-product yield in the associated chromite spiral recovery plant, with higher mass yields and hence revenue
