Hematite has a wide variety of other uses, but their economic significance is very small compared to the importance of iron ore. The mineral is used to produce pigments, preparations for heavy media separation, radiation shielding, ballast, and many other products.
Hematite is not made from calcium carbonate.
The chief form of iron ore is hematite, which is a mineral form of iron(III) oxide (Fe2O3). Hematite is a common iron ore that is widely used for extracting iron.
The best quality of iron ore is typically high-grade iron ore, which contains a high percentage of iron content and few impurities. High-grade iron ore is more valuable and in demand in the steelmaking industry because it requires less processing to extract the iron.

The mineral that leaves a grey streak and is metallic is likely hematite. Hematite is a common iron oxide mineral that has a metallic luster and leaves a grey streak when scratched against a rough surface like unglazed porcelain.
Iron is extracted from haematite.

Hematite is not made from calcium carbonate.
Hematite is a mineral made of iron and oxygen. It can be gray, red, or brown.
Hematite is black.
Chemical formula of hematite: Fe2O3
Iron is bonded to six oxygen ligands.
The main raw material for iron-making is iron ore.There are two iron ore minerals:haematite and magnetite.Actually haematite is an ore where iron is extracted.One can say that haematite is a source if iron.
Haematite is mined in Western australia, Hamersley province.
