Purpose of stirring blister copper with green logs of wood:
The purpose of stirring blister copper with green logs of wood is to reduce the metallic oxide impurities present in the blister copper. This process helps in refining the copper and obtaining a purer form of the metal.
Explanation:
- Reduction of metallic oxide impurities: When blister copper is melted in a furnace and stirred with green logs of wood, the hydrocarbon gases liberated from the wood act as reducing agents. These reducing agents react with the metallic oxide impurities present in the blister copper, leading to their reduction. As a result, the impurities are converted into their metallic form and separate from the molten copper, making it easier to remove them.
- Formation of slag: The impurities that are reduced form a slag on the surface of the molten copper. This slag can be easily skimmed off, leaving behind a purer form of copper known as refined copper.
- Carbon content: Although the process does involve the use of wood, the main purpose is not to increase the carbon content of copper. Instead, the focus is on reducing the metallic oxide impurities to refine the copper.
In conclusion, stirring blister copper with green logs of wood helps in the reduction of metallic oxide impurities, leading to the production of refined copper. This process is an essential step in the refining of blister copper to obtain high-quality copper metal.

Blister copper obtained from smelting and air is allowed to blow through and a flux must be added. Impurities are oxidised and escape as gases or pass into the slag. Finally, the surface of molten metal is covered with low sulphur coke (to prevent the oxidation of the metal) and green logs of wood are introduced into the molten metal and metal is stirred. The addition of green logs reduces the metallic oxide impurities with hydrocarbon gases liberated from the wood. This process is known as poling or furnace refining.
