  • Heap leaching Wikipedia

    In 2011 leaching, both heap leaching and in-situ leaching, produced 3.4 million metric tons of copper, 22 percent of world production. The largest copper heap leach operations are in Chile, Peru, and the southwestern United States. Although heap leaching is a low cost-process, it normally has recovery rates of 60-70%.Heap Leach: Mining's breakthrough technology MINING.COM,Aug 20, 2015· New techniques for tailings treatment and sulfide ore recovery will see low-cost environmentally friendly heap leaching take another giant leap forward. copper production.

  • Copper extraction Wikipedia

    Carbonate concentrates are a relatively minor product produced from copper cementation plants, typically as the end-stage of a heap-leach operation. Such carbonate concentrates can be treated by a solvent extraction and electrowinning (SX-EW) plant or smelted.Escondida Copper Mine Oxide Leach Expansion Ausenco,The Escondida Mine is located in the Atacama Desert, Chile. In 2012 it accounted for five per cent of global copper production and around 15 per cent of Chilean copper production. The mining operation includes an oxide ore heap leach plant processing approximately 20 mt/y of ore.
