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.

150 °C) Fe2 spontaneously forms magnetite without first forming Fe(OH) 2. This magnetite forms a nonporous tightly adherent layer on the metal surface. In most condensate systems two or three forms of iron oxide are present. In pure water a tightly adherent magnetite layer is formed which is indicative of a well-passivated iron surface.
