Abstract Effects of the nuclei ores on the granulation behavior of the low-titanium magnetite concentrate （LTC） were investigated using micro-drum granulation equipment in order to improve the granulation properties of the LTC. The results show that the LTC has coarse grain size， small specific surface area， and the granule morphologyof the LTC is mainly smooth irregular shape and the adhesion among granules is relatively week. The granulation index （GI） and uniformity index（UI）of the LTC are relatively high， the granulating efficiency and the uniformity of quasi-particles are not the restrictive link for the LTC granulation.There is no evident relationship between nuclei ores and the granulation index or uniformity index. Compared with other iron ores， the resistance index of the thermal disintegration （KI） of quasi-particlesis relatively high but the damage index （DI） exhibits the opposite behavior. The KI and DI of the quasi-particles varies greatly for the different nuclei ores. Given that there are three kinds of nuclei ores can be selected in the low-titanium magnetite concentrate granulation process， when the limonite acts as nuclei ore， the quasi-particles has the strongest capability of impact-resistance and hot pulverization resistance， but for the hematite， the capabilities of impact-resistance and hot pulverization resistance are comparatively worse， and the impact-resistance and hot pulverization resistance of the sinter return is the worst.
