13. In which district of Chhattisgarh bauxite mineral is available? [Chhattisgarh P.C.S. (Pre) 2019]

Correct Answer: (c) Kondagaon
Solution:According to IMYB, 2021, Bauxite mineral is available in Kabirdham, Kondagaon and Surguja districts of Chhattisgarh. Bauxite is a sedimentary rock with a relatively high aluminum content.

Bauxite is basically an aluminous rock that contains hydrated aluminium oxide as main constituent and iron oxide, silica & titania as minor constituents present in varying proportions.

It is the world's main source of aluminum and is typically found in tropical and subtropical regions. India accounts for 6% of global production, with the largest producers being Australia, the Republic of Guinea, China and Brazil.

Bauxite is the main source of the rare metal gallium. During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor.

14. Which of the following states has immense Tin Ore reserve? [U.P.P.C.S. (Pre) (Re-Exam) 2015]

Correct Answer: (c) Chhattisgarh
Solution:Chhattisgarh has immense deposits of tin ore. Notably, Chhattisgarh is the only tin producing State in India. As per IMYB 2021, about 64.4% of the total Tin ore Reserves/ resources are located in Haryana and 35.6% in Chhattisgarh.

15. Which are the largest Bauxite and Mica producing States in India? [Raj. P.C.S. (Pre) 2023]

(b) ChhattisgarhOdisha
(c) OdishaAndhra Pradesh
(d) JharkhandRajasthan
(e) Question not attempted
Correct Answer: (c)
Solution:According to the Annual Report, 2022-23 of Ministry of Mines. Odisha accounted for 73.13% of the total output of Bauxite during 2021-22 followed by Gujarat, Jharkhand and Chhattisgarh. Notably must important micabearing pegmatities occur in Andhra Pradesh, Bihar, Jharkhand, Maharashtra, Odisha etc.

16. Which mineral has the largest reserves in Chhattisgarh in the country? [Chhattisgarh P.C.S. (Pre) 2019]

Correct Answer: (c) Tin Ore
Solution:Chhattisgarh is the only tin-producing State in India. It also accounts for 35.4% of the tin ore reserves of India. Tin ore is known as cassiterite, which was reported in Dantewara district (Bastar district in formerly Madhya Pradesh) by the Directorate of Geology and Mining associated with the lepidolite bearing pegmatites.

Cassiterite-bearing pegmatites are reportedly rich in columbite and tantalite, which are ore of rare metals niobium and tantalum, respectively.

Lepidolite is also a source of rare alkali metals namely lithium (Li < 2.15%) cesium (Cs < 0.83%) and rubidium (Rb < 5.9%). Chhattisgarh has a population of 25.6 million. The state is currently power surplus and India's leading producer of coal, iron ore, and dolomite, with considerable reserves of minerals such as bauxite, limestone, and quartzite.

17. Top producer of Tin in India is - [U.P.P.C.S. (Mains) 2009]
