· Leaching Chalcopyrite is the holy grail for hydrometallurgists (Leachers), difficult to leach as the sulfur forms a layer over the mineral and makes the leaching slow. Having said that, it is not not leachable, not unusual for ore dumps (low grade) containing chalcopyrite to be placed under leach but report low recovery +/-30% TCu over several years and the rate is around 0.5-1% per month.
Introduction to Mineral Processing or Beneficiation
· Chalcopyrite does not in and of itself have any direct use as a mineral.
