    Miller Gold Refining Process by Chlorination. In order to purify gold and remove the silver from it by any process analogous to the cementation with nitre or salt in a reasonable time, the alloy must be in such a fine state of division that the silver will be removed almost instantly, or diffusion must be assisted by actually keeping the alloy in a molten state.

    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.
