How To Extract The Gold From Computer Circuit Gold in these circuits occurs as a layer over a base metal substrate such as nickel or coppereparate the goldplated metal parts in the circuit boards using a magnetome goldplated parts may be inside ceramic componentsut on the goggles and gloveslace all of the recovered circuit parts in one of the glass containers.
Containers for the boards (most people use 5 gallon plastic buckets) Before refining. Cut off those portions of the board that have gold. Discard the rest. Chips, which have gold inside as well as outside, must be broken open. On a small scale, one tap with a hammer should suffice. With lots of chips, you might want to use a cement mixer.
