Heap Leaching Mining Techniques, Metals Mining, Copper

Heap leaching is an industrial mining method to dig out precious metals and copper compounds from ore. Process of heap leaching . The mined ore is crushed into tiny chunks and heaped on an impermeable plastic and/or clay lined leach pad where it may be irrigated with a leach solution to melt the valuable metals. Sprinklers, or frequently drip irrigation, are used to minimize evaporation. The

Precious Metal Heap Leach Design and Practice Ore-Max

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. Thirty-seven different heap leach operations with a total production of 198 tonnes of gold per year (6,150,000 ounces/yr.) were surveyed to determine operating practice.
