Abstract:MHA (modified humic acid based) binder has been found as an effective substitution for bentonite in the pelletization of specularite concentrates. This study aimed to clarify the roasting behavior of specularite pellets with MHA binder under different oxygen atmospheres. The thermal behavior of the MHA binder was initially determined by TG-DSC, TG-FTIR and MRU gas analysis. The reducing gaseous products, such as CO and H2, affected the oxidation and consolidation of the specularite pellets with MHA binder due to the pyrolysis of organic matter in the MHA binder heated in air. The primary phase
