Reduction of Magnetite in the Presence of Activated Carbon Using Mechanical Alloying

Reduction of Magnetite in the Presence of Activated Carbon Using Mechanical Alloying

The reduction behaviour of magnetite using graphite under ball-milling conditions (using a planetary mono mill, Fritsch Pulverisette 6) has been investigated. The reaction of magnetite and graphite at different milling conditions leads to the formation of Fe2+ and Fe3+ species, the former increasing...

The reaction of magnetite and graphite at different milling conditions leads to the formation of Fe2+ and Fe3+ species, the former increasing at the expense of Fe3O4. Fe3O4 completely disappeared after a ball to powder ratio of 50 : 1 and beyond. The Fe2+ species were confirmed to be due to FeO using Mössbauer Spectroscopy and X-ray diffraction techniques.
