Regions in which iron ore has formed over millions of years e.g. through volcanism and can be mined economically are also referred to as iron ore deposits. Especially many ore deposits can be found in countries such as China, Australia, Brazil, India and Russia. These countries account for around 85 of the total global iron ore mining volume.

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite Fe 3 O 4, hematite Fe 2 O 3, goethite, limonite or siderite.Hematite is also known as quotnatural orequot.
