Magnetite - an overview | ScienceDirect Topics

Magnetite, ideal formula Fe 3 O 4, is an intriguing mineral, and not only because it is magnetic.The formula could be written as Fe 2+ Fe 3+ 2O 4, which more precisely designates one of its peculiarities.It contains both ferrous (Fe 2+) and ferric (Fe 3+) ions implying synthesis, growth, and stability within an environment where oxidized and reduced states of iron are present and maintained.

Hydrogen Reduction of Hematite Ore Fines to Magnetite Ore ...

Surplus coke oven gases (COGs) and low grade hematite ores are abundant in Shanxi, China. Our group proposes a new process that could simultaneously enrich CH4 from COG and produce separated magnetite from low grade hematite. In this work, low-temperature hydrogen reduction of hematite ore fines was performed in a fixed-bed reactor with a stirring apparatus, and a laboratory Davis magnetic ...

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 at the expense of Fe3O4. Fe3O4 completely disappeared after a ball to powder ratio of 50  ...
