Jun 07, 2021 · Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution. Concentration of the copper(II) sulfate solution by solvent extraction

why is scrap iron used to displace copper? economical

why is scrap iron used to displace copper? economical

Scrap iron is used to displace copper because it is a more reactive, cheaper metal, making it a cost-effective way to produce copper. Scrap or old iron is also easier to obtain, as it is one of the world’s most recycled scrap metals. During a displacement reaction, iron reacts with a copper sulphate solution

Plants absorb small quantities of metal ions through their roots. The plants are burnt as a renewable form producing electricity. If the metal is copper, sulfuric acid is added to make copper sulphate. In both phytomining and bioleaching, iron is added to displace the copper. Finally electrolysis is used to get pure copper metal. Useful metals

Iron is going to displace copper from it's sulfate and form iron sulfate. Iron sulfate, SO4 and plus we will get copper atom displaced, separated out. Similarly here zinc is more reactive so it will displace copper out from it's sulfate. And finally we will get zinc sulfate, zinc sulfate plus copper atom
