Iron ore mines are located in which of the following group of places?

Answer: (d) Singhbhum, Mayurbhanj, Keonjhar

Singhbhum, Mayurbhanj and Keonjhar are iron ore belts.

The idea

An iron-ore belt can extend across districts and State borders. A steel-plant town is a place where ore is processed, not necessarily where it is mined. Check the deposit family before treating all industrial or coal towns as iron-ore locations.

Why the others are wrong

(a) Bokaro is a steel plant; Hazaribagh is mica.

(b) Singareni is coal.

(c) Jharia and Raniganj are coal.

The trap

Steel plant towns are not ore mines.

Elimination technique

Singareni is a coal anchor, removing (b). Jharia and Raniganj remove (c), while Bokaro’s industrial role does not make the group in (a) an iron-ore group.

Noamundi, Gua and Kiriburu are Jharkhand iron-ore anchors; Gorumahisani and the Keonjhar belt are Odisha counterparts. Bailadila and Dalli-Rajhara form the Chhattisgarh family. Hematite and magnetite are the two principal iron-ore types to distinguish.
