Copper mining and the copper extraction process

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.

Copper Mining and Extraction Sulfide Ores

The electrolytic refining of copper produces the high quality, high purity copper required by industry. Even the best chemical method cannot remove all the impurities from the copper, but with electrolytic refining it is possible to produce 99.99% pure copper. Copper cathodes are hung between anodes.

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 ...

Refining (metallurgy) - Wikipedia

Copper Fire refining. The initial product of copper smelting was impure black copper, which was then repeatedly melted to purify it, alternately oxidizing and reducing it. In one of the melting stages, lead was added. Gold and silver preferentially dissolved in this, thus providing a means of recovering these precious metals. To produce purer copper suitable for making copper plates or hollow ...
