  • Method for producing an agglomerate made of fine material containing metal oxide for use as a blast furnace feed material
    Patent number: 9988695
    Abstract: The invention relates to a method for producing an agglomerate, which is used as a blast furnace feed material, by mixing a fine material containing metal and/or metal oxide, a mineral binder, which comprises a mineral raw material and a lime-based material, and optionally other additives to form a mass and solidifying the mass to form an agglomerate, wherein a raw material comprising a silicon oxide fraction of at least 40 wt %, a fine grain fraction of less than 4 ?m of at least 20 wt %, and a grain size fraction of less than 1 ?m of at least 10 wt % is used as the mineral raw material. The invention further relates to a blast furnace feed material that can be produced by means of the method according to the invention, and to a pre-mixture for producing the blast furnace feed material.
