Chemical mining can often be used to recover metals economically from materials that could not be so treated by more conventional mining, milling, and smeltering processes. A chemical mining plant usually requires less capital investment than a mine and mill plant. A chemical mining process usually increases a mine's ore sources and reserves.

Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (coppertin alloy) about 3000 BC, was the first engineering material known to man.

In its pure form, copper is relatively soft, and is malleable and ductile, meaning that it can be shaped or molded without breaking; for example, hammered flat into sheets or drawn out into wires. Copper is resistant to corrosion, and is a good conductor of heat and electricity (second only to silver).
