How is copper extracted from low grade copper ores ? |
|
Answer» Solution :The extraction of metals by using their aqueous solution is called hydrometallurgy. Example : AU, Ag, Cu etc. are extracted by this method. The copper from low grade ores and SCRAPS is extracted by hydrometallurgy. It is leached out using acid or bacteria. The solution containing `Cu^(2+)` is treated with scrap iron or `H_2`. `Cu_((aq))^(2+)+ H_(2(G)) to Cu_((s)) + 2H_((aq))^(+)`. |
