Extracting CuCl2 from used PCB etchant.

  1. Mar 23, 2015 #1
    Greetings all. I was wondering if any of you would know how exactly to extract copper chloride (CuCl2) from a solution of used pcb etchant. I know that when you react ferric chloride (the initial etchant) with copper, the products are FeCl2 and CuCl2 dissolved in a dark colored solution but how would i separate the 2 from there? I dont think boiling would help. If any of you know that would be great. Thanks.

    Are you interested just in recovering the copper? Or the copper chloride?

    I'm interesting in extracting the copper chloride but if that if not directly possible, I would also like to know how to recover the copper and then turn it into copper chloride.
