Beneficiation of low-grade, goethite-rich iron ore

2021-6-1  The use of a gaseous reductant to convert goethite to magnetite in low grade iron ore fines offers additional advantages over conventional reductants such as coal or coke. For example, traditional ironmaking processes such as the blast furnace emit large volumes of CO 2 contributing significantly to the global carbon budget.

Roasting conditions for the best conversion of goethite to synthetic magnetite were 600 °C in a gas atmosphere of 40:60 CO/CO 2, with a soak time of 20 min. Laboratory-based magnetic separations in a Davis tube indicated that a blast furnace grade (+62 wt% Fe) pellet concentrate could be produced with an acceptable iron recovery of > 88 wt%. Under both gas atmospheres, a higher reduction temperature of 1000 °C achieved a greater conversion of goethite to magnetite

DRY BENEFICIATION OF LOW-GRADE IRON ORE FINES

Magnetic separation is typically used in the beneficiation of high grade iron ores where the dominant iron minerals are ferro and paramagnetic [1,5]. Wet and dry low-intensity magnetic separation (LIMS) techniques are used to process ores with strong magnetic properties such as magnetite while wet high-intensity magnetic separation is used to separate the Fe-bearing minerals with weak magnetic properties such as hematite from gangue minerals. Iron ores such goethite and limonite are commonly found in tailings and does not separate very well by either technique [1,5]. Magnetic methods present challenges in terms of their low capacities and in terms of the requirement for the iron ore
