From Ore to Finished Product Copper
2022-1-2 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.

Applications of Electrolysis Electroplating
Copper purity can be enhanced by electro-refining. The same electroplating or electrodeposition principle is used in this case. The electrolyte is a copper ion solution, like copper sulphate. The cathode is a strip of pure copper and the anode is an unclean copper lump. At the anode: copper atoms dissolve to form copper ions from the impure copper.
