∙ 13y agoBacteria, fungi and plants may be able to extract copper from the ground when normal mining isn't efficient enough to do so. These methods have been developed in order to make mining easier, cheaper and better for the environment (it is nicer than a quarry to look at, there is no noise pollution and no habitats are destroyed).

How do you extract copper using dilute acid?
If you want to extract copper using dilute acid you must use sulphuric dilute acid.
