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.

Chloride heap leaching - BHP Billiton SA Limited

Sulfuric acid heap leaching of nickel. The technique is an acid heap leaching process like that of the copper method in that it uses sulfuric acid instead of cyanide solution to liquefy the target minerals from crushed ore. The process has been urbanized by European Nickel PLC for the rock laterite deposits of Turkey and the Balkans.
