Extracting Gold HowStuffWorks

­Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F 1,149 degrees C. When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers pour off the flux and then the gold.
