Abstract Scope |
Two copper – cobalt ore samples from Zebesha Mine in Zambia with varying amounts of nickel (0.02 – 0.45 weight %), manganese and iron were leached under different conditions with a purpose of understanding leaching characteristics. Leach test were conducted at different conditions such as pH, temperature and, in the presence and absence of reductant (SMBS). Acid consumption was decreasing with increase in leaching pH. Leach recoveries of Cu, Co, Ni, Mn and Fe were determined and the results were compared with thermodynamic predictions. Recoveries of Co, Ni and Mn were poor in the absence of SMBS. There was a good agreement between the experimental results and thermodynamic predictions. Recoveries of Cu and Ni were more sensitive to leaching pH. The feed samples were characterised using scanning electron microscopy and x-ray diffraction techniques. |
