Question

In which all places are iron ore mines found extensively?
(A) USA
(B) India
(C) Africa
(D) Brazil

Answer 1

Hint: Iron ores are rocks and minerals from which steel iron can be economically extracted. The ores are commonly prosperous in iron oxide and differ in colour from darkish grey, shiny yellow, or deep pink to rusty red. The iron is generally located in the shape of magnetite , hematite , goethite , limonite or siderite .

Complete Answer:
- Brazil is the primary producer of extraordinary iron-ore in the world. Chile and Peru are the most essential producers of copper. Brazil and Bolivia are amongst the world’s essential producers of tin. There are additionally big deposits of gold, silver, zinc, chromium, manganese, bauxite, mica, platinum, asbestos and diamond in South America.
- In Indian states of Chhattisgarh, Madhya Pradesh, Karnataka, Jharkhand, Odisha, Goa, Maharashtra, Andhra Pradesh, Kerala, Rajasthan and Tamil Nadu iron ores are located extensively. Metallic iron is certainly unknown on the floor of the Earth besides as iron-nickel alloys from meteorites and very uncommon varieties of deep mantle xenoliths.
- Some iron meteorites are thought to have originated from accreted bodies 1,000 km in diameter or larger. The foundation of iron can be subsequently traced to formation through nuclear fusion in stars and most of the iron is concept to have originated in demise stars that are massive sufficient to cave in or explode as supernovae.
- Although iron is the fourth-most ample aspect in the Earth's crust, composing about 5%, the enormous majority is certain in silicate or extra not often carbonate minerals (for extra information, see iron cycle).

Hence, the correct option is A,B and D.

Note: The thermodynamic obstacles to isolating pure iron from these minerals are ambitious and energy-intensive, consequently all sources of iron used with the aid of human enterprise make the most comparatively rarer iron oxide minerals, mainly hematite.
