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.
