Is Recovering Gold from Electronics Worth it?

Pour some borax onto the bowl. Borax is an alkaline mineral with a white, powdery appearance. It helps bring down gold's melting point below 1,948 degrees Fahrenheit, making it easier to melt the gold flakes. Transfer the gold flakes into the pot when the borax softens. Turn off the heat once the gold flakes turn into gold beads.
