    Synthesis of α-Fe2O3 nanoparticles by dry high-energy ball

    Nov 25, 2016 In this research, hematite nanoparticles (α-Fe 2 O 3 NPs) with spherical morphology were synthesized by high-energy ball-milling method for different milling times (40 and 60 h) at dry medium. The synthesized α-Fe 2 O 3 NPs were characterized by X-ray diffraction and field-emission scanning electron microscope (FE-SEM) techniques. An average particle size (APS) of α-Fe 2 O 3

    Hydrogen Reduction of Hematite Ore Fines to Magnetite

    Surplus coke oven gases (COGs) and low grade hematite ores are abundant in Shanxi, China. Our group proposes a new process that could simultaneously enrich CH 4 from COG and produce separated magnetite from low grade hematite. In this work, low-temperature hydrogen reduction of hematite ore fines was performed in a fixed-bed reactor with a stirring apparatus, and a laboratory Davis magnetic
