Are there any possible way to extract copper from waste CCL(copper clad laminate) for recycle or sel

    Currently the price of CCL has risen so rapidly, are there any
    possible way to extract copper from the waste CCL? If the wasted CCL
    is being sold in a form of waste, the price is obviously low but if it
    is being sold in a different form i.e. chemical that contains copper,
    etc.

    Any method or machine which will help me?

    thank you ^^
     
  2. Try stripping it with cupric chloride. You'll have to extract the copper
    with electrolysis.
     

  3. Electric furnace. It melts the copper, and burns the substrate.

    I'd do it carefully, so you can salvage the few milligrams of gold
    from edge connectors, bond wires, etc.

    Oh, and maybe silver:

    [some melting points, degrees C]:
    Silver Ag 961
    Gold Au 1064.58
    Copper Cu 1084.6
    (use fixed-width to see columns)

    Cheers!

    PCB houses already extract and recycle the copper from their used etchant.
    It may make sense to strip all of the waste laminate in the nearly-spent
    etchant, before recovering the copper out of it.
