Copper has a vast range of and industrial uses. Its superior electrical conductivity makes it ideal for electronics, such as wiring and computer connections; and its ability to heat up and cool down quickly makes it ideal for heat exchange applications such as air conditioners.

Data on copper mine capacity on a mine-by-mine basis are collected by the International Wrought Copper Council (Survey of Capacities of Copper Mines, Smelters, Refineries and Copper Wire Rod Plants, IWCC (2000)), and circulated within the copper industry. Fig. 2 shows how global mine capacity changed over the much shorter period of 1994–2002.
