The Mined copper ore is initially crushed, milled and concentrated by ore beneficiation process into a fine, gray powder called copper concentrate. If the nature of ore is sulphide, froth floatation process is adopted to do the beneficiation wherein the 1 % copper containing ore is converted to more than 25 % copper containing concentrate.
Cobalt is mined across the world and the vast majority is produced as a by-product from large scale copper and nickel mines.

Scrap is already in a metallic form, so we can think of it as "containing" all of the energy previously expended to mine, crush, transport, smelt and refine copper ore. Very little of that energy need be expended again since the re-melting and re-refining of scrap are relatively clean, efficient processes.
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 (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
