Define the following terms. (i) Mineral (ii) Ore (iii) Gangue
ScienceClass 10CBSEAnswered 27 Mar 2026
Answer
- Minerals are compounds (also known as elements) which are found naturally in the earth’s crust. E.g. Alums, K2SO4.Al2(SO4)3.24H2O, etc.
- Ores are minerals from which metal can be extracted Ex: Bauxite Al2O3.2H2O is the ore of Al, copper pyrite CuFeS2. All minerals are not considered as ores but all ores are also minerals.
- Ores mined from the earth are naturally contaminated with sand, rocky materials. There are impurities present in the ore which are known as gangue.
