The refiners will then pass an electric current through the cell. At the end of this process, the gold will be 99.99 percent pure. Reclaiming the Mine; No gold mine lasts forever. No one can predict how long any mine will last because it's different for each one. But usually after a few years, the gold in the mine is exhausted.
