  • Heap Leaching Mineral Processing & Metallurgy

    Heap leaching of gold and silver ores is conducted at approximately 120 mines worldwide Heap leaching is one of several alternative process methods for treating precious metal ores, and is selected primarily to take advantage of its low capital cost relative to other methods Thirtyseven different heap leach operations with a total production of 198 toHistory
  • Copper Heap Leaching & SXEW Slideshow MineralsEd

    Heap leaching & SXEW 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
