  • Sorption Process for Copper Recovery from Effluents of ...

    The sorption process is proposed for copper recovery from waste effluents of mining enterprises by applying the old condensed granulated pyrite-bearing concentrates with obtaining sulfide product of 4.5% in copper content, amenable to pyrometallurgical processing. Copper is precipitated on pyrite particles as a low-temperature modification of β-chalcosine. The sorption …

  • Oxidation of Pyrite

    2021-12-7 · The process of pyrite oxidation relates to all sulphide minerals once exposed to oxidizing conditions (e.g., chalcopyrite, bornite, molybdenite, arsenopyrite, enargite, galena and sphalerite among others). In other words, while the principal sulphide mineral in mine wastes is pyrite, other sulphide minerals are also susceptible to oxidation ...
