Separate the gold flakes from the solution by pouring it through a coffee filter. Allow the solution to drip through to a third glass beaker. The gold flakes will remain on the filter. Fill the plastic tray with water to half of its depth, place the remaining circuit board scrap in it and rinse. Pour this water through the filter to extract any remaining gold flakes.
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
