Explanation:

Statement 1: In India, the minerals are classified as minor minerals and major minerals. Central Government by notification in the Official Gazette declares minerals to be a minor or major mineral. The major- minor classification has nothing to do with the quantum /availability of these minerals, though it is correlated with the relative value of these minerals. Further, this classification is based more on their end use, rather than level of production, level of mechanization, export and import etc. (e.g. Sand can be a major mineral or a minor mineral depending on where it is used; same is the case for limestone.) Major minerals are those specified in the first schedule appended in the Mines and Minerals (Development and Regulation) Act, 1957 (MMDR Act 1957) and the common major minerals are Lignite, Coal, Uranium, iron ore, gold etc. It may be noted that there is no official definition for “major minerals” in the MMDR Act. Hence, whatever is not declared as a “minor mineral” may be treated as the major mineral. Major minerals are exploited by the Centre, and minor by the State.
