Copper | Uses, Properties, & Facts | Britannica
copper (Cu), chemical element, a reddish, extremely ductile metal of Group 11 (Ib) of the periodic table that is an unusually good conductor of electricity and heat. Copper is found in the free metallic state in nature. This native copper was first used (c. 8000 bce) as a substitute for stone by Neolithic (New Stone Age) humans.

Copper: introduction to the chemical element
Typically, copper ores contain only 4 percent copper, so the vast majority is waste. You can use a variety of different processes to separate the copper from the waste. The exact nature of the refining process depends on which metals and other materials the copper happens to be mixed with and how pure you need the final copper to be.

The Ancient History of Copper
The ability to extract copper from ore bodies was well-developed by 3000 BCE and critical to the growing use of copper and copper alloys. Lake Van, in present-day Armenia, was the most likely source of copper ore for Mesopotamian metalsmiths, who used the metal to produce pots, trays, saucers, and drinking vessels.

Turning Copper Ore into Copper: What are the Processes?
After the air is brought up through the water, bubbles form that float the water-repellent copper particles to the surface of the water. This separates out the froth which has 30% copper, 27% iron, and 33% sulfur. The flotation process gets rid of impurities in the ore, where there may also be lead and other vital metals in our society …
