Process for the production of a agglomerate of fine material containing metal oxide for use as a blast furnace feed material

摘要

A process for producing a chipboard, which is used as a blast furnace feed material, mixing a fine material containing metal and / or metal oxide, a mineral binder having a mineral raw material and a lime-based material, and where appropriate conventional additives to form a dough and consolidate the dough to form a chipboard by a sintering process, characterized in that as the mineral raw material a raw material containing clay ore is used that has a silicon oxide part of at least 40% by weight and a very fine grain part of less than 4 μm of at least 20% by weight, and a grain size part of less than 1 μm of at least 10% by weight.
