Question

The state where copper reserves are not found _____________.
A) Madhya Pradesh
B) Rajasthan
C) Tamil Nadu
D) Jharkhand

Answer 1

Hint: The future accessibility of minerals depends on the idea of stores and resources. Reserves are deposits that have been found, assessed, and evaluated to be productive. Resources are far bigger and incorporate resources, found and possibly productive deposits and unseen stores anticipated dependent on preliminary geographical studies. Copper is normally present in the Earth's covering.

Complete answer:
Worldwide copper reserves are estimated at 870 million tonnes (United States Geological Survey [USGS], and annual copper demand is 28 million tonnes. These copper resources are estimated to exceed 5,000 million tonnes.

India is critically deficient in the reserve and production of copper. Being malleable, ductile, and a good conductor, copper is mainly used in electrical cables, electronics, and chemical industries. The Balaghat mines in Madhya Pradesh, Khetri mines in Rajasthan, and Singhbhum district of Jharkhand are leading producers of copper. So, Tamil Nadu is the state where copper reserves are not found. Tamil Nadu is the leading holder of the country's resources of vermiculite, magnetite, dunite, rutile, garnet, molybdenum and ilmenite.

Chile, the world's leading copper maker by a wide margin, delivered an expected 5.7 million metric tons of copper in 2020. In second place is Peru, with an expected copper mine creation of 2.2 million metric tons around the same time. The world's third-biggest copper maker from mines in China.

Thus the correct answer is option ‘C’.

Note: Copper is among the main mechanical metals, positioning third after iron and aluminium as far as amount utilized. It is esteemed for its heat and electrical conductivities, flexibility, pliability, and protection from corrosion. Electrical utilizations represent around $\dfrac{3}{4} of the total copper utilization, including power links, information links, and electrical gear. It is likewise utilized in cooling and refrigeration tubing, heat exchangers, water lines, and consumer items.
