heap leaching copper ores

Heap Leaching Mining Fundamentals

2014 4 23&ensp·&enspHeap leaching is an industrial mining process of separating precious metals, copper, and other minerals, from ores. It involves a series of chemical processes, through which the mineral ores are piled into the form of a heap, and a leach solution is spread over the ore surface to leach metal from the heap.
