Copper is the most popular commodity (after uranium) that is mined by ISR (Table 1). There are references to primitive forms of in situ leaching of copper in Roman times, and maybe even long before that in China (O'Gorman et al., 2004). The San Manuel copper mine in Arizona is the best known copper mine exploited by ISR (O'Gorman et al., 2004).

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.

There are two basic types of mining: mining underground and mining at the earth's surface. Nearly two-thirds of the world's solid minerals are mined through surface mining. It is especially predominant in obtaining items such as coal, copper, sand, gravel, crushed stone, iron, aluminum, and phosphates.

The copper is recovered by electrolytic refining. Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off it can be used on ores with as little as 0.1% copper - for this reason, leaching extraction is growing in importance.

Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.

The Copper Age | The Bronze Age | The Middle Ages and Later | Mining. Copper minerals and ores are found in both igneous and sedimentary rocks. 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.
