    for magnetite is in the dense-medium washing process used in most coal preparation plants (Doral Resources NL 1990). This requires a suspension of finely milled magnetite in water. Magnetite is particularly well-suited to this application, because of its high density and recoverability by magnets for recycling (Evans 1993). Magnetite for coal
