Detailed explanation-1: -The process of extracting metal ores buried deep underground is called mining. The metal ores are found in the earth’s crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground.

Detailed explanation-2: -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-3: -Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore. Iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times.

Detailed explanation-4: -In principle, any metal could be extracted from its compounds using electrolysis . However, large amounts of electrical energy are needed to do this, so electrolysis is expensive.

Detailed explanation-5: -The primary methods used to extract minerals from the ground are: Underground mining. Surface (open pit) mining.
