The origin of the name copper was derived from the Latin word "cuprum" which means the island of "Cyprus".

Copper is one of the oldest metals ever used and is one of the most important materials in the development of civilization. The use of Copper has been known since prehistoric times where reports of its use date back to 9000BC, and evidence of mining and refining copper ore are dated at 5000BC. Copper is usually found in nature in association with sulfur, and also occurs in its native form. A common copper compound is CuFeS2 and is referred to as chalcopyrite. It is also found in many other mineral forms including malachite, cuprite, bornite and azurite.

Copper has a melting point of 1083.4 +/- 0.2°C, boiling point of 2567°C, specific gravity of 8.96 (20°C), with a valence of 1 or 2. Copper is reddish coloured metal and takes a bright metallic lustre. It is malleable, ductile, and a good conductor of electricity and heat

The production of pure copper metal is a multistage process, beginning with the mining and concentrating of ores containing copper sulfide minerals, followed by smelting, leaching and electrolysis to produce a pure copper cathode. Copper is commercially available at a purity of 99.999+ %.

Due to its properties of ductility, malleability, thermal and electrical conductivity, resistance to corrosion, copper has become a major industrial metal, ranking third after iron and aluminium in terms of quantities consumed. Electrical uses of copper, including power transmission and generation, building wiring, telecommunication, and electrical and electronic products, account for about 3/4 of total copper use. Building construction is the single largest market, followed by electronics and electronic products, transportation, industrial machinery, and consumer and general products. Copper by products from manufacturing and obsolete copper products are readily recycled and contribute significantly to copper supply.
