Metallurgy

Metallurgy is the process of extracting metals from their ores.

Minerals, Ores, and Gangue

  • Minerals: Natural substances in which metals and other impurities are found in a combined state.
  • Ores: Minerals from which metals can be extracted conveniently and profitably. All ores are minerals, but not all minerals are ores.
  • Gangue (or Matrix): Impurities associated with the ore.

FAQs on Metallurgy - General Awareness for SSC CGL

1. What is metallurgy and why is it important in the extraction of metals?
Ans. Metallurgy is the branch of science and technology that deals with the extraction, purification, and processing of metals. It is important in the extraction of metals as it provides the necessary techniques and methods to obtain pure metals from their ores.
2. What are minerals, ores, and gangue in the context of metallurgy?
Ans. Minerals are naturally occurring substances that are solid and have a specific chemical composition. Ores are rocks or minerals from which metals can be extracted economically. Gangue is the undesired material in an ore that has to be separated during the extraction process.
3. What are the steps involved in the extraction of metals through metallurgy?
Ans. The steps involved in the extraction of metals through metallurgy include mining of the ore, concentration of the ore, isolation of the metal from its ore, and refining of the metal to obtain pure form.
4. How does metallurgy play a role in the recycling of metals?
Ans. Metallurgy plays a crucial role in the recycling of metals by providing processes to extract and purify metals from recycled materials. This helps in conserving natural resources and reducing the environmental impact of metal extraction.
5. What are some common techniques used in metallurgy for the extraction of metals?
Ans. Some common techniques used in metallurgy for the extraction of metals include smelting, roasting, leaching, and electrolysis. These techniques help in separating the metal from its ore and obtaining it in a pure form.
