Iron formation

Iron-formation ores include primary and enriched varieties. Primary magnetite-rich ores are generally lower grade (<40 wt% Fe total) but have larger combined resources and reserves compared with enriched ores that have grades of 40 to 72 wt% Fe total.Enriched ores include early hypogene (magnetite, crystalline hematite) and later supergene (goethite–hematite) ore types.
