Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode. An increasing share of copper is produced from acid leaching of oxidized ores.

Copper is found at low concentrations in most marine, estuarine and fresh waters (Table 8.3.2 of the ANZECC & ARMCANZ 2000 guidelines). Copper is an essential trace element required by most aquatic organisms but toxic concentrations are not much higher than those that allow optimum growth of algae.

Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest ...

Approximately two tons of overburden must be removed along with each ton of copper ore. The ratio of overburden to ore is sometimes as high as 5 to 1. The ore itself averages less than 0.7% copper in US mines. Copper ore normally is crushed, ground, and concentrated, usually by flotation, to produce a beneficiated ore containing about 25% copper.
