Gold parting Wikipedia

Gold parting is the separating of gold from silver.Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum.With the advent of coinage, methods had to be invented to
