  • 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 .

  • Liquation - Wikipedia

    The copper-lead alloy created can be tapped off and cast into large plano-convex ingots known as 'liquation cakes'. As the metals cool and solidify the copper and the silver-containing lead separate as they are immiscible with each other. The ratio of lead to copper in these cakes is an important factor for the process to work efficiently .
