Blister copper is refined by stirring molten impure metal with green ...
Poling to Purify Blister Copper:
Poling is a refining process used to purify blister copper. It is a type of pyrometallurgical process that involves stirring molten impure metal with green logs of wood. The wood liberates hydrocarbon gases like CH4, which react with the impurities in the metal to form volatile compounds. These volatile compounds are then removed from the molten metal, leaving behind a purer form of the metal.
Steps involved in Poling:
1. Heating of the impure metal: The impure metal is heated to a molten state.
2. Addition of green logs of wood: Green logs of wood are added to the molten metal.
3. Formation of hydrocarbon gases: The wood liberates hydrocarbon gases like CH4.
4. Reaction with impurities: The hydrocarbon gases react with the impurities present in the metal to form volatile compounds.
5. Removal of volatile compounds: The volatile compounds are then removed from the molten metal using a vacuum or suction pump.
6. Purification of metal: The process of poling removes impurities from the metal, leaving behind a purer form of the metal.
Impurities in Blister Copper:
Blister Copper is an impure form of copper that contains impurities like Cu2O, Fe, S, and ZnO. These impurities can be removed using the poling process to obtain pure copper.

Blister copper is refined by stirring molten impure metal with green ...
Process of refining Blister copper using green logs of wood is called poling. The impurities in the blister copper is Cu2O.
Explanation:
Poling is a method used to remove impurities from metals such as copper. The process involves stirring a molten metal, in this case, blister copper, with green logs of wood. The wood releases hydrocarbon gases such as methane, which react with the impurities in the blister copper, such as Cu2O, forming a layer of slag on top of the molten metal. The slag is then removed, leaving behind a purified metal.
Blister copper is a crude form of copper that contains impurities such as Cu2O, FeS, and other metal sulfides. The impurities in the blister copper can affect the properties of the metal, making it brittle and less malleable. Therefore, it is essential to purify the metal before it can be used for various applications.
In the poling process, the green logs of wood are added to the molten blister copper, which is heated to about 1200°C. The wood reacts with the impurities in the metal, such as Cu2O, FeS, and other metal sulfides, producing hydrocarbon gases like methane, which rise to the surface and form a layer of slag. The slag is then skimmed off the surface, leaving behind a purified metal.
In conclusion, the process of refining blister copper using green logs of wood is called poling. The impurities in the blister copper are Cu2O, FeS, and other metal sulfides. The poling process removes these impurities, leaving behind a purified metal that can be used for various applications.
