1. Introduction. Iron ore pellets are nearly spherical agglomerates of fine iron ore, agglomerating agents and additives that are sintered in a furnace at temperatures of up to 1350 °C in oxidizing atmosphere [1].Handling and transportation of these pellets from the pelletizing plant to the reduction furnace of the steelmaker can cause …
