Fired iron-ore pellets having macro pores and process for producing the same

摘要

Fired iron-ore pellets are disclosed which are prepared by crushing iron ore to be pelletized, mixing a carbonaceous material of grain sizes ranging from 0.1 to 3 mm in diameter to the crushed iron ore in an amount of up to 4% by weight, pelletizing the mixture thus prepared, and firing the resulting pellets; thereby providing pellets throughout each of which is dispersed macro-pores of sizes ranging from 0.1 to 3 mm in diameter at a ratio of up to 25% relative to all pores contained in each pellet.
