ABSTRACT:
A new method for the preliminary treatment of the raw materials used for sintering of powdery iron ore is provided, in which the hydrophilic binder is dividedly incorporated in a first treatment step and/or a second treatment step. The solid carbon is also dividedly incorporated. The high productivity and quality of the product can thus be maintained and also the NOx conversion rate can be largely decreased.
