    A review of copperarsenic mineral removal from copper The common copperarsenic bearing minerals in copper ores, enargite (Cu 3 AsS 4) and tennantite (Cu 12 As 4 S 13), contain significant amounts of copper; 48.4% and 51.6% respectively. Removal of these minerals from the concentrate removes valuable metal, hence income. Get Price

  • Dissolution of Arsenic Minerals Mediated by Dissimilatory ...

    In turn, oxidation of arsenic-bearing sulfide minerals causes not only the release of arsenic but also the acidification of waters and their enrichment in sulfate anions and the accompanying heavy metals . Arsenic minerals dissolution can be mediated also at circumneutral pH, but mainly by sulfur- and arsenite-oxidizing microbes.
