Step-by-Step Gold Recovery From Circuit Boards ...

21/01/2014  Removing the Gold Gold can be removed from circuit boards in a variety of ways. It can be scraped off of the boards by hand, which is time consuming, but yields excellent results. The gold can also be removed via a process known as reverse electroplating, where a chemical solution and electricity are used to draw the gold off of the circuit board. Finally, gold can be removed by dissolving it in a
