21-01-2014· 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.

13-07-2010· There are several methods that are used practically to extract gold from a printed circuit board. But before we can start the process we need to determine the amount of gold that the PCB contains. It can be done by a procedure which is known as “ milling ”. You can mill the PCB yourself or you can take it to an assay laboratory for this purpose.

Method 1 Removing Gold Using Nitric Acid Get protective gear. Purchase concentrated nitric acid. Put your circuit boards in a glass container. Pour the concentrated nitric acid into the glass container with the circuit boards. Stir the mixture using a glass rod until the contents become fluid in form. Is it worth getting gold from computers?

Is Extracting Gold from Printed Circuit Boards Possible,13/07/2010 Extracting gold from a printed circuit board is definitely possible but the amount of the gold in the PCB has to be evaluated first. The process involves a number of steps which have to be carried out carefully in order to get the desired results.
