Iron ores are rocks and minerals from which metallic iron can be economically extracted. .. Currently magnetite iron ore is mined in Minnesota and Michigan in the U.S., Eastern Canada and Northern Sweden. .. rock must be comminuted to enable efficient magnetic separation to provide a high purity magnetite concentrate.
Automatic characterization of iron ore by digital microscopy and .
The present paper describes the current state of complete system for iron ore . All the image processing and analysis steps were performed in Fiji/ImageJ  and Octave  . Hematite, magnetite and goethite segmented regions can be seen in Fig. . while compact hematite follows to the 'Mono Poly Separation' step.
