Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper .
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted.
Copper mining in the United States has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2017 the United States produced 1.27 million metric tonnes of copper, worth $8 billion, making it the world's fourth largest copper producer, after Chile, China, and Peru. Copper was produced from 23 mines in the US.

Copper has a remarkable combination of properties. It is a good electrical and thermal conductor. It is ductile and it can prevent bacterial growth (see Copper: Properties and Applications). As with all world resources, the supply of copper from the ground is limited. Ever since copper was first mined.
Outfitted in hard hat, miner's headlamp and a yellow slicker, thousands of Bisbee visitors descend into the Queen Mine Tour each year—heading underground and back in time. Tour guides, retired Phelps Dodge employees, lead the group 1,500 feet into the mine and recount mining days, techniques, dangers and drama.
Mining metals: Metals are often found as compounds in ores.An ore is a rock or mineral that has enough metal in it to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1000 kg of ore.

The Great Ancient Copper Mines of Michigan. It is estimated that half a billion pounds (Ref.1) of copper were mined in tens of thousands of pits on Isle Royale and the Keweenaw Peninsula of Michigan by ancient miners over a period of a thousand years.
The copper is recovered by electrolytic refining. Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off it can be used on ores with as little as 0.1% copper - for this reason, leaching extraction is growing in importance.
