Copper Heap Leaching & SX-EW Slideshow
Heap leaching & SX-EW is a method of extracting pure copper from oxide ore by placing the crushed ore on a pad in a heap and spraying the leaching solution, sulphuric acid, over the heap. The acid trickles through the heap and dissolves the copper mineral into solution. The leach solution collects at the bottom of the pad in a collection pond.
Ammonia Leaching: An Alternate Route for Copper Recovery
The use of ammonia as a leaching agent in the recovery of copper from ores and concentrates has a number of potential benefits. These include the ability to treat ores with an acid consuming gangue, non-corrosivity, the insolubility of iron in the solution and increased selectivity. This paper reviews the previous and current use of ammonia …

SART for copper control in cyanide heap leaching
The problem of copper leaching is compounded when multiple lifts are placed on the heap (as is usually the case). Old lifts buried under active leaching areas can continue to slowly leach copper and consume free cyanide in the process. It is possible to install impermeable liners on top of old lifts, but this is expensive, technically difficult ...
