Abstract

THE PRESENT INVENTION DESCRIBES A PROCESS FOR THE HEAT TREATMENT OF FINE-GRAINED IRON ORE AND FOR THE CONVERSION OF THE HEAT-TREATED IRON ORE TO METALLIC IRON, IN WHICH@@A)THE FINE IRON ORE IS REACTED WITH AT LEAST ONE BINDER TO PRODUCE PARTICLES HAVING A PARTICLE SIZE OF > 0.1 TO 5MM,@@B) THE PARTICLES ACCORDING TO PROCESS STAGE (A) ARE DRIED,@@C) THE PARTICLES DRIED ACCORDING TO PROCESS STAGE (B) ARE HEAT-TREATED AT A TEMPERATURE OF 700 TO 1100?C,@@D) THE HEAT-TREATED PARTICLES ARE REACTED TO FORM METALLIC IRON.
