radomiro heap leaching flowsheet

Mining engineering: summary Alejandra Pizarro Técnica

Heap Leaching. In contrast to dump leaching, heap leaching refers to the appliion of chemicals to lowgrade ore that has been crushed and deposited on a specially designed pad lined with synthetic or natural materials such as polyethylene or compacted clay. Copper heap leach operations are much smaller than copper dump leaches.

The Chemistry Of Copper Heap Leaching europeanmasters.be

Heap leaching Wikipedia. Nickel ores. The method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore. The amount of sulfuric acid required is much higher than for copper ores (as high as 1,000 kg of acid per tonne of ore,.
