Effect of Humic Acid Binder on the Preparation of Oxidized Pellets from Vanadium-Bearing Titanomagnetite Concentrate

In order to pursue the goal of low-carbon ironmaking, a new type humic acid (HA)-based binder was applied preparation oxidized pellets from vanadium-bearing titanomagnetite (VTM) in this work. Effects HA (or with limestone) on balling, preheating, and roasting behaviors VTM were comparatively studied bentonite. The embedded features each mineral phase sintered pellets, especially crystallization growth state hematite grains, deeply investigated by XRD, optical microscopy, SEM–EDS measures. dosage can be cut down 50% when used instead Fine grains evolved into plump interlocking ~5% limestone addition. Pseudobrookite magnesioferrite spinel formed at optimal sintering temperature 1250 °C, which could hinder affect strength final pellets.
