Abstract
Mossbauer spectroscopy, X-ray photoelectron spectroscopy, infrared spe ctroscopy, electron paramagnetic resonance and X-ray diffraction were used to identify changes of surface, structure and spectroscopic prope rties of sulfide minerals produced by mechanical activation. In the pr esent study we report the results of chalcopyrite (CuFeS2), Pyrite (Fe S2), cinnabar (HgS), bornite (Cu5FeS4) and zinc sulfide (ZnS). The inf luence of energy input to the mill and the nature of grinding environm ent have been investigated upon the Fe contamination of the materials.
