Oxidation of chalcopyrite by extended milling ScienceDirect

Dec 01, 2005· After 20 h milling, the peaks for chalcopyrite were absent. The only phases which could be confirmed as present were Fe 2 O 3, CuSO 4 ·5H 2 O and S. Further milling to 50 h resulted in crystallite refinement of these phases with the concomitant weakening and broadening of the peaks making positive identification difficult.

Mar 01, 1999· Fig. 1 illustrates the XRD pattern 2 for the as-received chalcopyrite. Pyrite and quartz are also present, as would be expected (see Table 1, Table 2).After 28.8 ks of simultaneous autogenous milling and leaching, chalcopyrite is not detected, but synthetic nantokite (CuCl) becomes the dominant pattern (see Fig. 2).This would seem to suggest that the reaction (1) CuFeS 2 +4FeCl 3 →CuCl 2
