Describe the extraction process of copper.
Answers
Answer:
Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. ... The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate.

In this e-source, we’ll look at the ways of extracting copper from the ground.
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, it has been recycled. Today, nearly one third of demand for copper is met through recycling, helping to conserve the earth’s resources.
Copper is very well suited to being recycled because it can be remelted endlessly with no loss of properties. For example, old copper plumbing pipes, taps and car radiators are a major source of recycled copper. They can all be melted down and made into new products. Even the few grams of copper in your mobile phone is worth recovering.
Copper is an unreactive metal, it reacts only slowly with the atmosphere. This means that huge lumps of copper metal are found buried in the ground as nuggets. This is called native copper. The largest nugget of native copper ever found came from Minnesota, USA and weighed over 400 tonnes. Native copper isn’t mined because there is so little of it. Therefore it is of little commercial importance.
