The authors have developed a series of humic substances-based binders for iron ore pelletizing. This work was to gather information for the further industry application of humic substances-based binders in the field of iron ore oxidized pellets production. Pyrolysis of humic substances as the active fraction in the binders and its effects on fired hematite pellets was investigated in this study. Pyrolysis product of humic substances was focusing on four main gases (CO2, CO, H2and CxHy). The results demonstrated that effect of O2/N2atmosphere on weight loss of humic substances is obvious above 600 °C. Instantaneous concentration of gas products is increased with increasing pyrolysis temperature. Weight percentage of CO2 is increased obviously with increasing O2 concentration, while those of CO and H2 decreasing.
