Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit mining, in which a series of stepped benches are dug deeper into the earth. Yet, it can also be mined underground, through horizontal tunnels.

1996-11-20 discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
