Abstract: A process for producing cold-bonded or non-fired iron ore which introduced as a charge into a blast furnace. The iron ore, which contains 10 to 70% of particles having a diameter ranging from 1 to 10 mm, is molded into a block, preferably by a pressure-molding method, a shock-molding method or a packing-molding method with vibrations. The block is then cured or hardened. This hardened block is crushed to have a predetermined shape. An additive such as CaO, Al.sub.2 O.sub.3, or MgO may be added to the iron ore to adjust the basicity as a whole to 0.8 to 2.0. Moreover, the molding step is conducted so that the product may have a void volume equal to or less than 25%.
