Mined ore which has a copper grade of less than 1% is turned into copper concentrate with a purity of about 30% at mine site and transported to the Toyo Smelter & Refinery. In addition to copper, copper concentrates contain about 30% each of iron and sulfur, and trace amounts of gold, silver and other precious metals, all of which are recovered.

For proper heap design for cyanide leaching of copper-bearing gold ores, it is necessary to run long-term column tests (typically 60 to 180 days) at two or three different cyanide and/or pH levels. The relationships between gold-silver-copper recoveries, cyanide levels, and leach times will be different for each orebody. Since gold-copper types of
