18.1.1 Key gaseous emissions from sinter plants. Iron ore sintering is a material preparation process employed worldwide in the production of iron and steel. According to statistical data on pollution, sintering plants rank second in terms of toxic emissions, after the incineration of municipal solid waste (Menad et al., 2006; Remus et al., 2013).
Seven open-pit iron ore mines (each with associated concentration and pelletizing plants), and three iron metallic …
2 1 INTRODUCTION In recent years, fine iron ore concentrate production, also referred to as pellet feed, increased as the availability of new lump ore and high quality sinter fines declined

The present work proposes a novel process to sinter porous iron ore (porosity ~23–24%) with enhanced productivity and quality. The iron ore is pre-processed in the presence of calcined lime for the temporary closure of pores, which further prevents water absorption during the granulation process in drum in the presence of water. The …
