Magnetite Lodestone Mineral Photos Uses Properties

Use of Magnetite as an Ore of Iron Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite hematite and chert Once considered a waste material taconite became an important ore after higher grade deposits were depleted Today s commercial taconites contain 25 to 30 iron by weight...
