ABSTRACT OF THE DISCLOSURE This invention relates to fired iron-ore pellets having at least two precipitated slag phases of different chemical compositions which appear among iron-oxide grains. The pellets having two different slag phases contain not less than 4% by weight of CaO + SiO2, so that large cracks may be produced in the course of reduction. The cracks thus formed cause each pellet to be split into several pieces. The fired iron-ore pellets of the present invention exhibit excellent and improved reducibility than do the ones of the prior art. A process for producing these fired iron-ore pellets is also disclosed.
