A new kind of iron ore pellet binder named humic acid modifying bentonite (HA-MB) has been developed by the author’s group, which has the advantages of both organic HA and inorganic bentonite. The green pellet strength can be obviously improved by using the HA-MB binder. In this study, the detection of the characterization of HA-MB was conducted by zeta-potential, TG-DSC, FTIR, XRD, etc. The addition of HA was able to change the zeta-potential of bentonite. And HA-MB had more weight loss than that of bentonite according to TG-DSC analysis. Some functional groups of HA were also found in the FTIR spectrum of HA-MB. XRD result indicated that d(001) of crystal layer of bentonite had apparently altered due to the addition of HA.
