Abstract

Pellets and a process for producing them, the pellets having sizes that range from 14 to 25mm and aggregating coal, limestone and bentonite as additives, the process of producing the pellets comprising the steps of: a) adding to a ground (88%<325&num;) iron ore concentrate additive: H2O, coal, limestone and bentonite; b) causing said concentrate to roll on a balling disc, bringing about agglomeration of the material and forming the green pellets; c) sorting the pellets by sizes, selecting those with sizes ranging from 14 to 25 mm; d) returning the pellets smaller than 14mm and bigger than 25mm to the balling disc; e) firing the pellets in a straight grate, where sintering of the pellets take place between the oxides.
