Question

______ is the best quality iron ore.

पर्याय

• Magnetite

• Lignite

• Hematite

• Anthracite

Answer 1

Magnetite is the best quality iron ore.

Explanation:

Magnetite is considered as the finest quality iron ore because it has the largest proportion of metallic iron, up to 70% to 72%. It naturally has significant magnetic characteristics, making it extremely valuable in specialised areas such as the electrical sector. In comparison, hematite is the most often used industrial iron ore, but it contains slightly less iron (60% to 70%), whereas Lignite and Anthracite are coal rather than iron ore.
