Iron Ores | ispatguru.com

Hematite is a steel-gray to iron- black colored mineral which is as hard as magnetite (Moh’s scale hardness is 5.5 to 6.5) but slightly less heavy (usually specific gravity varies from 5.0 to 5.3). It has also a metallic luster. The three primary sources of iron ore are banded iron formations, magmatic magnetite ore deposits, and hematite ore.
