Processing Gold Ore With Electrolysis

The gold is separated from the solution by either running it over zinc shavings or by means of electrolysis. In either case the gold is deposited as a black mud and is periodically collected and refined. In electrolysis the solution flows continuously through vats containing either lead or tin plate cathodes and oxidized lead anodes.
