Which Indian mineral resource term is correctly associated with classification or identity “the principal ore used for aluminium production”, and also with “it commonly forms through intense lateritic weathering”?

Correct Answer: Option A — Bauxite. Bauxite is correctly identified as the principal ore used for aluminium production. Bauxite is also associated with it commonly forms through intense lateritic weathering. 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 B — Mica: Mica is a sheet-silicate mineral group that splits into thin elastic sheets. It is incorrect here because Mica is instead associated with traditional mica belts are associated with Jharkhand, Andhra Pradesh and Rajasthan. • Option C — Copper Ore: Copper Ore is a metallic resource valued for electrical conductivity and ductility. It is incorrect here because Copper Ore is instead associated with Khetri in Rajasthan, Malanjkhand in Madhya Pradesh and Singhbhum in Jharkhand are important associations. • Option D — Limestone: Limestone is a sedimentary rock composed mainly of calcium carbonate minerals. It is incorrect here because Limestone is instead associated with large deposits occur across several states including Rajasthan, Madhya Pradesh, Andhra Pradesh and Chhattisgarh. Exam Takeaway: Connect Bauxite with “the principal ore used for aluminium production” and “it commonly forms through intense lateritic weathering” for revision.
