Q70. Which ore is considered the finest grade of iron ore?
[Madhya Pradesh Teacher Eligibility Test, 16 May 2023]
(A) Anthracite
(B) Haematite
(C) Magnetite
(D) Lignite
Answer: (C) Magnetite
Explanation: Magnetite has very high iron content and strong magnetic properties, giving it a reputation as a high-grade iron ore. Haematite is also commercially important but contains a smaller theoretical iron percentage. Anthracite and lignite are types of coal, not iron ore.
Q69. Which statements about the location of Tata’s Jamshedpur steelworks are correct?
(1) It enjoys transport links.
(2) It lies near the Subarnarekha and Kharkai rivers.
(3) It can access iron ore from Noamundi and Badampahar.
(4) It can obtain coking coal from Jharia and West Bokaro.
[SSC Junior Engineer, 9 October 2023]
(A) 1, 2, 3 and 4
(B) 2 and 3 only
(C) 1, 3 and 4 only
(D) 1, 2 and 3 only
Answer: (A) 1, 2, 3 and 4
Explanation: Jamshedpur’s location combines water from nearby rivers, iron ore from the Odisha–Jharkhand belt, coal from Damodar Valley fields and established transport links. These complementary advantages explain its development as a leading integrated steel-production centre.
Q68. Which of the following is regarded as the finest iron ore?
[KVS Post Graduate Teacher Geography, 18 February 2023]
(A) Haematite
(B) Magnetite
(C) Mica
(D) Cobalt
Answer: (B) Magnetite
Explanation: Magnetite is an iron oxide with a theoretical iron fraction above 70%, making it exceptionally iron-rich. Haematite is another main ore but has a somewhat lower iron fraction. Mica is non-metallic and cobalt is a different metallic element.
Q67. Which statement about iron ore in India is incorrect?
[MPPSC State Service Preliminary Examination (2022 Cycle), 21 May 2023]
(A) Haematite and magnetite are major iron ores.
(B) Eighty percent of India’s iron ore occurs only in Jharkhand and Odisha.
(C) Ballari is an iron-ore region in Karnataka.
(D) Mayurbhanj is an iron-ore region in Odisha.
Answer: (B) Eighty percent of India’s iron ore occurs only in Jharkhand and Odisha.
Explanation: India’s iron-ore resources are spread across several regions, including Odisha, Jharkhand, Chhattisgarh, Karnataka and Goa. Limiting roughly eighty percent of all iron ore to only Jharkhand and Odisha overlooks other substantial resource belts. The remaining location statements are sound.
Q66. Which state leads India in iron-ore production in the referenced period?
[Odisha Police Sub-Inspector, 26 November 2023]
(A) Jharkhand
(B) Karnataka
(C) Odisha
(D) Bihar
Answer: (C) Odisha
Explanation: Odisha has been a leading iron-ore-producing state, with major deposits in Keonjhar, Mayurbhanj, Sundargarh and neighbouring districts. High-grade haematite supports steel plants and exports. Production rankings vary by year, but Odisha occupied the first position in the exam’s reference period.
Q65. Which of the following is a metamorphic rock?
[SSC MTS, 14 September 2023, Shift 1]
(A) Conglomerate
(B) Sandstone
(C) Basalt
(D) Slate
Answer: (D) Slate
Explanation: Slate forms when shale or similar fine-grained sedimentary rock is subjected to heat and pressure. Sandstone and conglomerate are sedimentary, whereas basalt is igneous. Recognising rock types is useful because particular mineral deposits are associated with particular geological settings.
Q64. Kolar is historically famous for mining which mineral?
[SSC MTS, 14 September 2023, Shift 1]
(A) Coal
(B) Gold
(C) Petroleum
(D) Copper
Answer: (B) Gold
Explanation: The Kolar Gold Fields of Karnataka were historically among India’s best-known gold-mining centres. They are associated with ancient rocks of the southern peninsular shield. Although large-scale operations declined, Kolar remains a standard landmark in Indian mineral geography.
Q63. Which mineral was extracted at the famous Kolar Gold Fields?
[Delhi Police Constable, 29 November 2023, Shift 2]
(A) Gold
(B) Silver
(C) Limestone
(D) Copper
Answer: (A) Gold
Explanation: The Kolar Gold Fields are in Karnataka and are associated with extensive historical gold mining. Gold mineralisation is linked to ancient greenstone belts and related geological formations. This distinguishes Kolar from major copper, limestone and coal mining areas elsewhere in India.
Q62. Which pair is NOT recognised as a major iron-ore belt of India?
[SSC CHSL (2022 Cycle), 17 March 2023, Shift 2]
(A) Maharashtra–Goa
(B) Haryana–Rajasthan
(C) Odisha–Jharkhand
(D) Durg–Bastar–Chandrapur
Answer: (B) Haryana–Rajasthan
Explanation: India’s major iron-ore belts include Odisha–Jharkhand, Maharashtra–Goa, Durg–Bastar–Chandrapur and the Ballari–Chitradurga belt. Haryana–Rajasthan is not generally listed as a principal national iron-ore belt, although isolated iron occurrences exist in different states.
Q61. In which state are the Kolar Gold Fields located?
[SSC CHSL (2022 Cycle), 15 March 2023, Shift 3]
(A) Jharkhand
(B) Kerala
(C) Karnataka
(D) Andhra Pradesh
Answer: (C) Karnataka
Explanation: Kolar lies in Karnataka, east of Bengaluru. It is historically important for gold production and for demonstrating the association of gold-bearing veins with ancient peninsular geological formations. The location should not be confused with gold occurrences in other Indian states.
