Iron, as commonly available, nearly always contains a certain small percentage of carbon, which is picked up from the coke during the process of smelting. This results in modifying its properties, from hard and brittle cast irons containing up to 4% carbon to more malleable low-carbon steels containing less than 0.1% carbon.
So, the ore of iron is haematite with the chemical formula F e 2 O 3. Suggest Corrections.
Hematite, heavy and relatively hard oxide mineral, ferric oxide, that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance. Its name is derived from the Greek word for 'blood,' in allusion to its red color. Learn more about hematite in this article.

Detailed Solution. Fe2O3 is the chemical formula of an iron ore called Hematite. Hematite is one of the most abundant minerals on the Earth's surface. Fe2O3 have an iron oxide with a chemical composition. It is a common rock-forming mineral discovered in sedimentary, metamorphic, and igneous rocks.
Goethite is a common iron oxide mineral that has a chemical formula of FeO (OH). It is often referred to as "limonite" although that term is used more broadly to describe a mixture of various iron oxides and hydroxides. Goethite is an important mineral in various geological and environmental contexts due to its widespread occurrence and …
From raw iron ore mined from the earth to the refined metal used in countless applications, the process is intricate and fascinating. This article delves into the types and characteristics of iron ore, the methods of processing it into steel, and the global distribution of these crucial raw materials.
