  • Sulfuric Acid-Oxygen Leaching for In-Situ Extraction

    Hydrometallurgical treatment of chalcopyrite by sulfuric acid based systems for primary recovery of copper is limited by the refractory nature of the mineral (Bartlett, 1973; Gerlach et Chalcopyrite Wikipedia,Chalcopyrite is present with many ore-bearing environments via a variety of ore forming processes. Chalcopyrite is present in volcanogenic massive sulfide ore deposits and sedimentary exhalative deposits, formed by deposition of copper during hydrothermal circulation.

  • Copper leaching from chalcopyrite concentrates

    These processes recover copper via hydrometallurgical leaching of the copper component of chalcopyrite concentrates, followed by solvent extraction and electrowinning. A number of demonstration plant operations have been conducted, but as of this writing none of the processes have become completely commercially operational.Kinetic study of copper leaching from chalcopyrite,Comparing with the chalcopyrite content and Cu grade of the original concentrate (95 and 28.8%, respectively), 54% of chalcopyrite and 18.6% of copper in the residue are acceptable numbers based on 42% of copper extraction.
