Computer circuit board scrap was first treated with one part concentrated nitric acid and two parts water at 70°C for 1 h. This step dissolved the base metals, thereby liberating the chips from the boards. After solidliquid separation, the chips, intermixed with some metallic flakes and tin
When the aqua regia is no longer effective (no longer dissolves the gold on the boards), it is time to recover the pure gold from the solution. The acid will be a dark, emerald green color and should be clear, like Coca Cola, not murky or muddy looking (nothing floating inside the dark waters). If the acid is murky, it may contain particles and

All electronic devices contains inside of them circuit boards, in this article we will discuss about the most common circuit boards that can be found in a normal computer.
The term scrap gold recovery refers to the process of extracting gold from old circuit boards, computer chips, computer parts and connectors. Depending on your source of the aforementioned this can be a very affordable way for you to obtain gold.
circuit board fingers, found inside computers, are covered in gold plating and look like fingers that insert into connectors within the computer. People collect or purchase old, obsolete computers for the purpose of recovering gold from the computer's electronics. In order to recover enough gold to make a profit, you need to collect a hundreds of
Remove any gold-plated pins and connectors by breaking the boards where the pins are. Leave a small section of circuit board attached to the pins to avoid losing any gold from them. Step. Sort the remaining scrap into piles for later recovery of lesser metals and smaller amounts of precious metals.
Gold, silver, platinum and palladium can all be recovered from circuits and processors of electronics. Of all the precious metals, gold is the one most frequently recovered and refined from electronics. Although it is possible to melt the gold plating away from the circuitry, you will cause more of a mess and lose some of the precious metal.
Aug 13, 2014· Back in the 70's I extracted the gold, copper and solder from from about a 100Kg of salvaged circuit boards. Even with the thicker gold used in those days I didn't get enough total return to cover the total cost of the processing.
Can anyone tell me if it is worth reclaiming the gold from the circuit boards and connectors So I wanna to know about this process of recovering the gold from
