Question

___ was the only gold mine in India that had to be closed down.
A) Balaghat mines.
B) Khetri mines
C) Kudremukh mines
D) Kolar goldfield

Answer 1

Hint: The extraction of precious minerals or other geological elements from the Earth, usually from an orebody, lode, vein, seam, reef, or placer deposit, is known as mining. The miner is interested in these deposits because they constitute a mineralized commodity.

Complete answer:
Kolar Gold Fields is a mining zone in the Kolar district of Karnataka, India. It is located in the K.G.F. taluk. It is headquartered in Robertsonpet, which is home to Bharat Gold Mines Limited and BEML Limited personnel and their families.

Let us look at the given options:
A) Balaghat mines: This option is incorrect Bhalaghat mines are located in Madhya Pradesh and the mineral that is mined in this mine is Manganese.
B) Khetri mines: This option is incorrect because copper mines are famous in Rajput's Khetri mines. The 'Tamba Project' is located 10 kilometres from Khetri and is known as Khetri Nagar. Hindustan Copper Limited, a public sector under the "Government of India" and under his supervision, created Khetri Nagar.
C) Kudremukh mines: This option is incorrect because in 2006, the Kudremukh mine, one of the world's largest iron ore mines, was shut down. On the Western Ghats range, captive mining took place at Kudremukh.
D) Kolar goldfield: This is the correct option. The Kolar Gold Field is located in Karnataka's Kolar District. It's a mining area. About 30 kilometres from Kolar and 100 kilometres from Bangalore, the Kolar goldfield is located. In the east, there is a ridge of hills known as Doddabetta Hill. For nearly a century, this town was famed for its gold mining. The mine closed on 28 February 2001 It was India's sole gold mine that had to be shut down. Due to the low level of gold production, it was eventually closed.

Thus, the correct answer is Option (D) i.e, Kolar goldfield.

Note: The town has been recognised for gold mining for almost a century. Despite the presence of gold, the mine closed on February 28, 2001, due to a drop in gold prices. In 1889, one of India's first power plants was developed to serve mining operations. Between the 1960s and 1992, the mine complex hosted some particle physics experiments.
