Gold and silver are products of the copper mining and smelting process. They follow the same production pathway as our copper ore from the mine to the smelter. At the refinery, we lower copper anodes (which contain gold and silver) into an acid solution. Gold and silver drop off into the bottom of the tank as electrolytic slimes.

60 Centuries of Copper: Early Smelting Practice

Sep 24, 2018· Early Smelting Practice. Virtually all the ore used by the ancients was handpicked with only the most worthwhile material being taken. Originally it was probably smelted by the Sumerians in shallow pits using charcoal as the fuel.
