From Ore to Finished Product
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.

Copper demand, supply, and associated energy use to 2050
The anticipated decrease in ore grade will lead to an increase in the energy required per ton of produced copper, mainly in the mining and mineral processing stage (Fig. 2 (b); Norgate and Jahanshahi, 2010). The future energy required for primary copper production is then estimated by Eqs. (3q) and (3b).
