Final answer:
Pyrometallurgy and electrometallurgy are two different processes used in metallurgy to extract metals from their ores. Pyrometallurgy involves the use of heat, while electrometallurgy utilizes electricity.
Step-by-step explanation:
Pyrometallurgy and electrometallurgy are two different processes used in metallurgy to produce metals from their ores. Pyrometallurgy involves the use of heat to extract metals from their ores. This process usually involves smelting, which is the application of heat and a chemical reducing agent to decompose the ore and extract the metal base. For example, in the smelting of iron ore, the reaction can be represented by:
2Fe2O3 + 3C → 4Fe + 3CO2
On the other hand, electrometallurgy involves using electricity to extract metals from their ores. It utilizes electrolytic cells, where an electric current is passed through a molten metal compound or an aqueous solution of a metal compound to facilitate the migration of ions and the deposition of metal at the cathode.
Overall, the main difference between pyrometallurgy and electrometallurgy is the energy source used to extract metals - heat in pyrometallurgy and electricity in electrometallurgy.
