Jul 13, 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. There are some instruments and acids involved in the process. Necessary precautions must be taken before starting the procedure.
Check the boards to make sure all the gold has been removed and dissolved into the aqua regia acid. Remove the basket from the acid, taking care not to drip acid anywhere. The aqua regia is not used up yet, so you can use the same acid to dissolve the gold off more boards. You can continue to use this acid, several times, to dissolve the metal ...
