How to build a circuit for an electrochemical to extract different metals

  1. Jul 6, 2011 #1
    Hello All,

    I am trying to build what is essentially an electrochemical cell which I will use to filter waste water and try to recover gold silver and copper among other metals on a High Surface Area Cathode like Carbon.I want this electronic filter to be selective about the metals recovered based on their positions in the electrochemical series. How could I go about that? I was thinking I could start at low voltages first eg: 0.5v then the next cell would have maybe 0.9 v and the next 1.3 v then 2v in that order.

    Any suggestions as to the circuit needed parts operating principles? is it possible?
