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. Thirty-seven different heap leach operations with a total production of 198 tonnes of gold per year (6,150,000 ounces ...

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
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%.

TENORM: Copper Mining and Production Wastes Within the United States, mining and production of copper are primarily located in the West, specifically Arizona, New Mexico, Utah, Nevada and Montana. According to the United States Geological Survey (USGS), production in these states and Michigan account for more than 99% of domestic copper production.
Much work has been done on the effect of copper in cyanide solutions on the leaching of gold. It is generally accepted that copper in cyanide solutions can form complex ions such as Cu(CN)2-, Cu(CN)3=, and Cu(CN)4=-, although Cu(CN)3= is considered the most probable of these. According to leach scientists, the complex having an empirical formula KCu(CN)2, is not a solvent for gold and silver.
The study was performed using electronic waste with high copper contents. The electronic components were manually separated from each of the printed cards (EW-PCB), leaving only the substrate with traces of welding ().Once selected, a preliminary milling was performed and the EW-PCB was classified by particle size.
