chalcopyrite minerals processing methods

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 100 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 051 per month
