Chalcopyrite Leaching

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 05-1% per month ....

Nickel Heap Leaching

Heap Leaching is an ancient process; leaching metals out of ore goes back nearly 500 years Mines in Hungary recycled copper-bearing solutions through waste heaps in the 1550s, Spanish miners percolated acid solutions through large heaps of oxide copper ore on the banks of the Rio Tinto in 1752 and one of the classical methods for the manufacture of copperas (iron sulphate) was to heap up iron ....
