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. As in all mining operations, the ore must usually be beneficiated. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper

Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituentssuch as alumina, limestone, pyrite, and silicaso that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.

Extraction of copper from suitable ore by leaching methods is generally assumed to cost less than the combined expense of concentration, smelting, and refining, and experimental data tend to confirm this opinion. At the ButteDuluth plant, which is handling in excess of 100 tons of oxidized ore daily, the copper is said to cost $0.085 per pound.
