Nov 15, 2022Iron ore is a type of rock from which metallic iron can be economically extracted. Hematite and Magnetite are the two principal iron ores found in the earth. Most of the iron ore deposits are found in sedimentary rocks. The ores are formed by the combination of iron and oxygen in fresh and marine water, through a chemical reaction.
