Metallurgy, in the context of Class 10, refers to the branch of science and technology that deals with the extraction and refinement of metals from their ores. It encompasses various processes and techniques aimed at obtaining pure metals or their alloys from naturally occurring mineral deposits.
Metallurgy plays a crucial role in our everyday lives as metals are widely used in industries, construction, transportation, and many other fields. The study of metallurgy helps us understand how metals are formed, how they can be extracted from ores, and how they can be processed and transformed into useful products.The process of metallurgy involves several steps. It starts with mining, where ores are excavated from the earth’s crust. These ores may contain a variety of minerals and impurities. The next step is the concentration of the ore, which involves removing unwanted materials and increasing the metal content. This is achieved through processes like froth flotation, magnetic separation, or leaching.
After extraction, the metal is subjected to purification processes to remove any remaining impurities. These purification methods can include techniques such as electrolysis, fractional crystallisation, or zone refining.
