The formation of FeS2 from a Fe3S4 precursor in the external magnetic field strength of 0.2 similar to 0.4 T has been experimentally examined. In the reaction system of FeCl3-CH4N2S at 170 degrees C, the conversion rate of Fe3S4 to FeS2 was found to be magnetic field strength dependent. The sulfidation of Fe3S4 may proceed via dissolution and precipitation mechanism, the presence of an external magnetic field could promote the mass transport process and then accelerate the dissolution and crystallization processes, resulting in faster conversion rate of Fe3S4 to FeS2 than that in the absence of an applied magnetic field.
