Abstract Scope |
Pelletizing serves as a valuable method for the agglomeration of iron concentrates. In this study, the pelletizing behaviors of commonly used magnetite and hematite concentrates were investigated based on pelletizing experiments using a laboratory disc pelletizer. It was demonstrated that the bentonite dosage and moisture content of green pellets considerably affected the pellets quality. For magnetite concentrate, to achieve qualified green pellets with minimal binder addition, the optimal pelletizing parameters were as follows: a bentonite dosage of 1.5 wt.%, a pelletizing time of 12 minutes, and a green pellet moisture content of 8.43 wt.%. For hematite concentrate, the corresponding parameters were: a bentonite dosage of 1.5 wt.%, a pelletizing time of 8 minutes, and a green pellet moisture content of 11.31 wt.%. The differences between the quality of the pellets from these two concentrates were closely associated with different wettability characteristics of the concentrates. |
