2014-11-1  Complementary XRD analysis showed that the chalcopyrite sample contained 6.3 wt.% pyrite while the pyrite contained 10% impurities of virtually no copper sulphide. A two stage grinding procedure (primary grinding to d 80 of 105 μm and secondary grinding to d 80 of 10, 20, and 30 μm) was used to produce the feed for this study.
