The early development of copper probably was most advanced in Egypt.As early as 5000 bce, copper weapons and implements were left in graves for the use of the dead.Definite records have been found of the working of copper mines on the Sinai Peninsula about 3800 bce, and the discovery of crucibles at these mines indicates that the art of extracting the metal included some refining.

For copper oxide ore, electrowinning is the final stage in the process of hydrometallurgy, in which concentrated copper solution from the heap leaching and solvent extraction processes is used as an electrolyte an electric current is applied through an inert anode, resulting in the plating of copper onto 99.9 pure copper cathodes.

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.
