  • Galvanic Interaction between Chalcopyrite and Pyrite with

    This study was aimed to investigate the galvanic interaction between pyrite and chalcopyrite with two types of grinding media (low alloy and high carbon chromium steel ball) in grinding of a porphyry copper sulphide ore. Results indicated that injection of different gases into mill altered the oxidation-reduction environment during grinding.


    If the process works in the range of pH 7-8, i.e. almost neutral, at this pH-range dichromate falls out as chrome oxides, Cr2O3(s) and chrome hydroxide, Cr(OH)3 (s) (aq). Any excess of Cr (VI) is reduced to Cr (III) with iron (II) sulfate, added at the end of the flotation process, and will precipitate as Cr(OH)3 (s). Most of the chromate will
