  • How to Refine Gold From Electronic Scrap |

    How to Refine Gold From Electronic Scrap |

    The electrolyte solution you made will dissolve the gold from the scrap, and the positive charge in the gold will cause it to attract to the negatively charged steel. All of the gold in the electronics scrap will form onto the steel, where it can be peeled off and set aside until you have enough to refine.
