Copper is leached out using acid or bacteria. The solution containing Cu2+ ions is treated with scrap or H2 to recover copper.
Cu2+(aq) + Fe(s) ---------> Cu(s) + Fe2+(aq)
Cu2+(aq) + H2(g) ---------> Cu(s) + 2H+(aq)

How is copper usually found in nature?
i think they mine itCopper 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 cathode. An increasing share of copper is produced from acid leaching of oxidized ores. Nearly as much copper is recovered from recycled material as is derived from newly mined ore.

What are the content of copper ore?
There are several ores of copper but more common are sulphide ores as Copper pyrite CuFeS2, along with iron and sulphur other contents are silicates of calcium and Magnesium.
How copper ores are transported?
Via extra large trucks.
The real name for copper ore?
The most common ore of copper is Copper pyrite CuFeS2 but other ores are also exist.
What is the difference between Copper- rich ores and Low - grade ores?
Copper rich ores contain Relatively large amount of copper. Copper obtained from rich ores is from better quality than low-grade ores. A low-grade ore doesn't contain very high proportion of valuable copper
What is the difference between a copper rich ore and a low grade ore?

What is the cost of extracting copper from low grade ores?
1000 dollars

Is hydrometallurgy used in mining copper?
Hydrometallurgy is used for the processing of copper.Example: Leaching of copper oxide ores using a solution containing sulphuric acid. The Copper can then be recovered from solution using solvent extraction and electrowinning.
What is the problem with using low-grade ores as a copper source?
The metal (copper) extracted may be generally brittle and break easily.
What are ores of copper?
the ores of copper are chalcopyrite .malachite .azurite. and native copper.
What are the problems associated with using low grade ores?
It's poor quality and not all the copper can be extraxted from it
What is hydrometallurgy?
The use of aqueous solutions for the recovery of metals. Example: Leaching of copper oxide ores using a sulphuric acid solutions (or solution containing sulphuric acid). The Copper can then be recovered from solution using solvent extraction and electrowinning.
What has the author Robert L Hoye written?
Robert L Hoye has written: 'Gold/silver heap leaching and management practices that minimize the potential for cyanide releases' -- subject(s): Environmental aspects, Environmental aspects of Leaching, Gold ores, Leaching, Silver ores
What is the ores of copper?
Ores of copper(Cu) are: -Chalcopyrite -Malachite -Azurite Native copper can also be found.
What is copper phytomining?
The world is running out of rich copper ores. Research is being carried out to find new ways to extract copper from the remaining low-grade ores, without harming the environment too much. This research is very important, as traditional mining involves huge open-cast mines that produce a lot of waste rock.Some plants absorb copper through their roots. As a result of this they concentrate these compounds as a result of this. The plants can be burned to produce an ash that contains the copper compounds. This process is known as photomining.
