    Extraction Of Gold

    The extract is transferred to tanks, and the gold precipitated as a powder by addition of zinc. It is then washed out from the bottom of the tanks, dried, and freed from zinc by roasting and fusing. In the electrolytic precipitation of the gold an iron anode and a sheet-lead cathode are employed, the current-density being very low, about 0.5 amp. per sq. metre.

    Dec 05, 2019 Put the rock powder in a mining pan. A mining pan has holes in the bottom of it like a colander. Because gold is heavy, it will sink to the bottom of the mining pan even while its submerged in water, while the other minerals wash away. Pour a layer of rock powder onto the mining pan so you can extract the gold pieces.
