ABSTRACT OF THE INVENTION This invention relates to an iron ore pellet having specially excellent properties as the raw material of iron in the production of pig iron and to a method of making the same and also to a method of operating a blast furnace. Conventional iron ore pellets, due to their spherical shape, are liable to ununiformalize the layer thickness distri- bution of the materials charged in furnace resulting in reduction in operational efficiency of blast furnace. In the present invention, after a powdered iron ore has been subjected to granulation and firing into spherical pellets, a further crushing is applied while adjustment of a particle size of crushed pellet is made so that the outer surface of the pellets is composed of spherical formed surfaces and crushed surfaces. By doing so, improvements are made in the angle of repose and in the reducing characteristic of iron ore pellets and eventually an efficient and highly economical blast furnace operation is attained.
