  • Hydrometallurgy - an overview | ScienceDirect Topics

    The process of converting solid metals into ions in aqueous solution by using a leaching agent produced though the catalysis of microorganisms is called bioleaching (Brandl, 2008). In 1947, Colmer et al. isolated At. ferrooxidans from acid mine drainage and found that the strain could oxidize Fe 2 + into Fe 3 + to leach copper from pyrite ...

  • Leaching of CuO Nanoparticles from PES Ultrafiltration ...

    Nov 30, 2021 · Based on the measured CuO concentration, 0.1 M HCl resulted in more leaching of the nanoparticles and the leaching order was 0.1 M HCl > 0.5% NaClO > 0.1 M NaOH > 0.1 M NaCl > water. The leaching order makes sense, considering that the PES polymer has a limited working pH range (3.5–10) outside of which it is prone to chemical alterations.
