"Spatial variations in leaching of a low-grade, low-porosity chalcopyrite ore identified using X-ray μCT" - Marijke A. Fagan-Endres, Johannes J. Cilliers, Andrew J. Sederman, Susan T.L. Harrison

  • X-ray μCT used to quantify the proximity of mineral to the ore particle surface.
  • Effect of proximity to surface on leaching efficiency studied over 102 days.
  • Maximum leaching penetration of 2 mm observed for this low grade chalcopyrite ore.
  • Higher recoveries observed at column wall, possibly due to preferential flow.
