Open-pit copper mining, smelting, and production Britannica

In the final extraction step—refining—any remaining minor impurities are removed from the anodes. The result is almost 100 percent pure copper. This metal will be sent to other plants to be made into products such as copper pipe and copper wire. Most of the world's production of copper is used by electrical industries.

Copper mining and the copper extraction process explained

Reasonable quality, high conductivity copper can be recycled by melting, though copper that has been brazed needs refining or can be used to make copper alloys. Where are the most important copper regions and producers? The largest copper mining country in the world is Chile, which produces 5.5 million tonnes per year.

Jul 08, 2019 Copper smelting and refining facilities produce 2.5 million metric tons (MT) of smelter slag and 1.5 million MT of slag tailings per year. This is a large volume of slag, however, it is very small compared to comparable waste volumes from mining and crushing operations.

Innovations: Introduction to Copper: Mining & Extraction

Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest
