<p>A process for improving the reactivity, permeability and/or similar characteristics of an ore charge being subjected to down-draught sintering, characterized by including into said charge an active quantity of a micropelletized product produced by balling a fine-grained ore material with the addition of a minor quantity of hydraulic binder and water to a maximum agglomerate size of up to 10 mm (preferably up to 6 mm) which prior to charging onto said sintering device is cured to in average at least50% of the maximum achievable cured strength or of the cured strength obtainable by curing for 28-30 days at room temperature. </p> |
