  Comparative investigations on sulfidic gold ore processing: …

  2019815 · A two-step biooxidation process is proposed by several research groups. The sulfides are leached with biogenic ferric iron at elevated temperature using the ferric iron containing solution produced during the second biooxidation step. The second step is the biooxidation of the products of the first step by microorganisms.
