ABSTRACT:
The present invention relates to a method to improve the iron production rate in a blast furnace being charged by iron containing agglomerates. The method includes contacting the chargeable iron containing material with a slag modifying effective amount of a dispersion of a particulate material, wherein the contacting occurs prior to the charging of the agglomerate to blast furnace process.
