  • Gold Refining Techniques Sciencing

    Gold refining, or parting, is used to separate gold from impurities and other metals, such as silver. Gold and silver, which are often extracted from the same ores, are chemically similar, making them difficult to separate. Before the advent of processes to separate silver and gold, a gold-and- silver alloy called electrum was frequently used.
