Hematite is an ore of iron. It is a dark red rock from which we get iron. It has a red or brown colour with an earthy lustre. It is a heavy and usually hard oxide mineral that constitutes the most important iron ore. It is derived from the Greek word "blood" in allusion to its red colour. It is the most important iron ore in the world.

In the paper are shown the history, processing and applications of hematite. Hematite is an oxide of iron having the composition Fe2O3. Pure hematite, also called "red ore" contains 70% Fe.
However, more than 97% of the iron ore is low-grade refractory iron ore (LGRIO) resources, such as limonite, siderite, and high phosphorus oolitic hematite (Roy et al., 2020;Yu et al., 2020). ...
The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and …
In many parts of India, because of depletion in high grade iron ore, efforts are focused on the use of low-grade iron ore for steel production.
