In order to refine copper it, is melted in a furnace and it is stirred with green logs of wood. The purpose is:
(a) To expel the dissolve gas in a blister copper.
(b) To reduce the metallic oxide impurities with hydrocarbon gases liberated from the wood.
(c) To bring the impurities to surface and oxidise them.
(d) To increase the carbon content in copper.
