Copper can be extracted by hydrometallurgy but not zinc as per the below-given reason:

The E^o of zinc ( Zn²⁺/Zn = - 0.76V) is lower than that of copper (Cu²⁺/Cu = 0.34V). this means that zinc is a stronger reducing agent and can displace copper from a solution of Cu²⁺ ions.

Zn (s) + Cu²⁺ (aq) → Zn²⁺ +
