If So, What Is The Matrix?What Is The Concentration of The Target Metal(S) in Solution?Are There Any Other Metals Or Impurities in Solution?What Is The Throughput Or Production Rate?Can I Recover Copper from this?This question is important because not all metals can be recovered by electrowinning. The ability to recover the metals depends on their respective positions in the Electrochemical Series. The Electrochemical Series arranges redox reactions according to their standard potentials relative to hydrogen ion (H+). More noble metals such as silver and copper are good at accepting electrons and therefore easy to electrowin. More reaSee more on blog.emew
