摘要： Mini-pellets made of raw materials of fine powder iron ores are indurated, and effected with diffusion bond. A plurality of said treated mini-pellets are combined with calcium ferrites at the surface layers thereof. Thus, agglomerated ores are produced, wherein main grain sizes of said fine powder iron ores are not more than 5 mm, and are subjected to a primary pelletization with flux, and solid fuels are coated in a secondary pelletization to produce the mini-pellets of 3 to 9 mm diameter, and the produced mini-pellets are undertaken with induration in a travelling grate typed sintering furnace.Depending upon the present agglomerated ores and the producing method therefor, the raw materials may be selected from a wide range of grain sizes, and a blow faculty is enough to be small, and producing yield of the agglomerated ores may be increased, having improved qualities of high RI and low RDI.
