Typically, a deposit must contain at least 25 percent iron to be considered economically recoverable. This percentage can be lower, however, if the ore exists in a large deposit and can be concentrated and transported inexpensively (Weiss 1985). Over 300 minerals contain iron but five are the primary sources of iron-ore minerals: magnetite (Fe,O4).
