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.

What Is Copper Smelting? (with pictures)

A pot made out of copper. Matte is then poured into a converter where it reacts with air, lime, and silica to separate the copper from iron slag. The resulting copper from this step is known as blister copper. Blister copper undergoes further firing and purification to remove any remaining impurities.
