GoldCopper Ores ScienceDirectJan 01, 2016· 1. Introduction. The association of gold and copper mineralization in commercially viable ore is a common occurrence. At one end of the spectrum is the predominantly copper ore, which contains levels of gold mineralization.

From the gold of aluminum bronzes to patina green (e.g., the Statue of Liberty), the diverse colors of copper and copper alloys, or metals in which copper is the principle component, make it unique. The most wellknown copper alloy families are brass (copperzinc), bronze (coppertin) and coppernickel.

Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.

Typical mines today have ore grades of only 0.6 percent copper. Since metal concentrations occur at much lower grades, the copper concentrations are measured in parts per million (ppm). If a sample has 1ppm copper, this means that in 1 million lbs of rock, there is 1 lb of copper.
