INDIAN GEOGRAPHY

Detailed explanation-1: -The mining process involves the excavation of large amounts of waste rock to remove the desired mineral ore. The ore is then crushed into finely ground tailings for chemical processing and separation to extract the target minerals.

Detailed explanation-2: -Minerals can be extracted by mining, drilling or quarrying. For minerals near the surface quarrying is done to extract them.

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: -The correct option is A Smelting. The process in which metals are extracted from their ores by heating them beyond the melting point is called smelting. The molten mix is then refined and processed further to obtain the output, steel.

Detailed explanation-5: -The mining industry operates through a sequence of stages: exploration, discovery, development, production and reclamation. All stages of this Mining Cycle provide direct economic stimulus.
