Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. In this chapter, the sintering process is first described to identify the key steps of the process, that is, granulation and thermal densification. Discussion is then focused on the effect of the chemical, physical, and ...

In steel manufacturing, the sintering process is the main emission source of PCDD/Fs followed by the electric arc furnace process (Zhu et al. 2016). Studies performed on iron ore sintering plants have indicated that PCDD/Fs are formed through a de novo synthesis, taking place in the sinter bed in regions where the temperature is 250–450 °C.

The continuous sintering process was invented more than 60 years ago by two metallurgists, Arthur S. Dwight and Richard L. Lloyd, who saw a need for automation in mineral processing. Their specific objective was to beneficiate copper ore by desulfurizing and agglomerating it for copper blast furnace smelting at the Cananea plant in Mexico.
