POR Le Heap Leach Machine Fir Gold

Apr 30, 2021

Because capital and operating costs are low, heap leaching is applicable to large low-grade deposits. The largest heap leach operation in the U.S. processes 7,200 tons per day of ore containing 2.2 ppm gold. One operation in Nevada heap leaches, profitably, 1,100 tons per day of ore containing only 1.2 ppm gold; the

    Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to
