Which Indian mineral resource term is correctly associated with course, basin or associated feature “important deposits occur in Odisha and several plateau and hill regions of central and western India”, and also with “alumina is extracted from bauxite before electrolytic aluminium smelting”?

Correct Answer: Option C — Bauxite. Bauxite is correctly identified as important deposits occur in Odisha and several plateau and hill regions of central and western India. Bauxite is also associated with alumina is extracted from bauxite before electrolytic aluminium smelting. Another identifying fact about Bauxite is that important deposits occur in Odisha and several plateau and hill regions of central and western India. A further exam-relevant fact about Bauxite is that alumina is extracted from bauxite before electrolytic aluminium smelting. Why the other options are incorrect: • Option A — Mica: Mica is its electrical and thermal insulating properties support industrial use. It is incorrect here because Mica is instead associated with muscovite and phlogopite are important mica varieties. • Option B — Copper Ore: Copper Ore is chalcopyrite is a common copper-bearing sulphide mineral. It is incorrect here because Copper Ore is instead associated with copper is used in electrical equipment, alloys and construction. • Option D — Limestone: Limestone is it is the principal raw material for cement manufacture. It is incorrect here because Limestone is instead associated with it is also used as a flux in iron and steel processing. Exam Takeaway: Connect Bauxite with “important deposits occur in Odisha and several plateau and hill regions of central and western India” and “alumina is extracted from bauxite before electrolytic aluminium smelting” for revision.
