Beneficiation of low-grade, goethite-rich iron ore using …
Microwave-assisted magnetizing roasts were used to produce an iron ore product from low-grade, goethite-dominant, iron ore plant rejects. Goethite was found to be converted to hematite at temperatures above 370 °C on reduction in a microwave furnace under gas mixtures of 30:70 and 40:60 CO/CO 2. Reduction to magnetite occurred at …
