Gold parting

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 remove impurities from the gold

Ways to Separate Metal From Ore Sciencing

The process of separating a metal from its ore is known as smelting. Smelting is widely practiced today and has a long history dating back to the Bronze Age, when ancient peoples first learned the technique. Smelting methods range from the basic to the high tech, and are applied to a variety of materials, including aluminum, iron and copper.

Extracting Gold HowStuffWorks

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon in pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
