Method for Producing an Agglomerate Made of Fine Material Containing Metal Oxide for Use as a Blast Furnace Feed Material

Agglomerate, produced by a sintering process for use as a blast furnace feedstock, comprising

• metal- and/or metal oxide containing fines, that comprise a proportion of intermediate grain sizes between about 0.2 mm to 0.7 mm of more than 30% wt., and
• a mineral binder comprising a mineral raw material and a lime-based material, wherein the mineral raw material
• contains a clay mineral, and
• comprises a silicon oxide proportion of at least 40 wt.% and
• a finest grain proportion of less than 4 μm of at least 20 wt.%, and
• a grain size proportion of less than 1 μm of at least 10 wt.%.
