For this reason, the material needs to be big enough so that there are spaces between each piece. On top of this, the ore needs to be strong enough not to be crushed thereby obstructing the blast furnace. Thus, the production of pellets is fundamental to the steel production process. This is the fuction of the New Vale Pellotizing Plant – Plant 8.
In the pelletizing process, iron ore concentrate is rolled into balls (pellets) and hardened through thermal treatment in an induration furnace. The induration furnace is the primary source of emissions from this sector of sulfur dioxide (SO 2 ), inhalable particles with a diameter of microns or less (PM ), and oxides of nitrogen (NO x );
