The iron oxide mineral magnetite as Fe 3 O 4 has a mass percent of 72.36% Fe and 27.64% O and typically occurs as a natural ore containing 15–40% Fe. Historically hematite direct shipping ore (DSO) has been the preferred source of iron ore globally, with significant resources located on several continents, including Australia in the Hamersley Range, Western Australia.
In the process, low grade iron ores are dry-ground, preferably to their liberation size & passed through a fluidized bed roaster. The process uses coal gas for pre-heating & for partial reduction. Hematite / limonite / goethite ores get converted into magnetite ore in 1-10 minutes depending on the size of iron ore, at temperatures of 500-600 ...
