2016-12-4 plants consistently produced concentrates of more than 71 pct Fe. Edison devoted eight years, at a cost of more than $2 million, to inventing a magnetic process and con- structing a plant for concentrating low grade iron ore into desirable furnace feed.

Read MoreMagnetite is an iron oxide formed by Fe3+ and Fe 2+ cations that can be represented by the chemical formula (Fe 3+) tet (Fe 3+ Fe 2+) oct O 4, although it is more commonly represented by the chemical formula Fe 3 O 4. The presence of ferrous ions in their structure ensures unique redox properties.
