Explanation:
Detailed explanation-1: -The process of extracting metals from their ores is called metallurgy. The process employed in the extraction of the ore depends on the nature of the ore and the impurities present in it. The following are the basic steps for a metallurgical operation: Crushing and grinding of the ore.
Detailed explanation-2: -Metallurgy consists of three general steps: (1) mining the ore, (2) separating and concentrating the metal or the metal-containing compound, and (3) reducing the ore to the metal. Additional processes are sometimes required to improve the mechanical properties of the metal or increase its purity.
