FAQs on Metallurgy of copper PPT Chemistry Class 12

1. What are the main properties of copper that make it valuable in metallurgy?
Ans.Copper is valued in metallurgy for its excellent electrical conductivity, thermal conductivity, malleability, ductility, and resistance to corrosion. These properties make it an essential material in electrical wiring, plumbing, and various industrial applications.
2. What are the primary methods of extracting copper from its ores?
Ans.Copper is primarily extracted from its ores through two main methods: pyrometallurgy and hydrometallurgy. Pyrometallurgy involves smelting the ore at high temperatures to separate copper from impurities, while hydrometallurgy uses aqueous solutions to leach copper from ores.
3. What are the common alloys of copper and their applications?
Ans.Common alloys of copper include bronze (copper and tin) and brass (copper and zinc). Bronze is known for its strength and corrosion resistance, making it suitable for marine applications, while brass is valued for its machinability and aesthetic appeal, often used in fittings and musical instruments.
4. How does the process of annealing affect copper?
Ans.Annealing is a heat treatment process that relieves internal stresses in copper, improving its ductility and reducing hardness. This process allows copper to be easily shaped and formed, making it more workable for various applications.
5. What role does copper play in electrical applications?
Ans.Copper is crucial in electrical applications due to its high electrical conductivity, which ensures efficient transmission of electricity with minimal energy loss. It is widely used in electrical wiring, circuit boards, and components in electronic devices.
