HEAP LEACHING OF COPPER ORE HEAP LEACHING PROCESS The mined

HEAP LEACHING PROCESS: COPPER LEACHING COUPLED WITH SX/EW CONSISTS OF THE FOLLOWING STEPS: Application of a sulfuric acid solution to the top of a heap. Interaction of the leach solution with the ore and gangue minerals within the heap. Stoichiometric exchange of one copper ion for two hydrogen ions in the SX plant. Recirculation of the copper depleted solution back onto the heap.

In heap leaching the ore is usually heaped as it comes from the mine without any breaking on crushing treatment. Frequently, pieces of rock 5 or 6 feet across a face are found in the heaps. Solution is added to the ore at the surface and seeps downward by gravity and is collected in a solution sump.

There are two main leaching methods: heap leaching and insitu leaching. Heap leaching is the most common method used in the U.S. When processing copper through heap leaching, vast quantities of ore and overburdenoverburdenSoil and rocks that have been moved out of the way to get to ore are called "overburden.".
