Innovations in Copper: Mining & Extraction: Producing copper …
Prior to the development of the solvent extraction-electrowinning (SX/EW) process in 1959 (see Copper the Green Metal), the only way to recover copper from an acid solution was by a process called cementation. In this process, copper was in effect "traded" for iron by contacting the copper-bearing solution with scrap iron.
How Do You Mine Copper Ore: A Guide to the Extraction Process
Copper ore is typically mined through two primary methods: open-pit mining or underground mining. In open-pit mining, large pits are dug into the earth using heavy machinery, and the ore is extracted from the rock. Underground mining, on the other hand, involves tunneling into the earth to reach the copper deposits. 2.

Chemistry of Copper
The symbol and name for copper are from the Latin cuprum, which literally means "from the island of Cyprus", an early source of copper ore. Before 1982 U.S. pennies were pure copper. Now they are mostly zinc with a thin shell of copper. Most copper that is mined today is refined and drawn into wire for use in the electrical industries.
Copper | Geoscience Australia
Copper is soft but tough. It is easily mixed with other metals to form alloys such as bronze and brass. Bronze is an alloy of tin and copper and brass is an alloy of zinc and copper. Copper and brass are easily recycled¿perhaps 70% of the copper now in use has been recycled at least once. The Properties of Copper.

copper extraction and purification
Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper (II) sulphate solution. Concentration of the copper (II) sulphate solution by solvent extraction.
From Ore to Finished Product
4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction. The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6.
