A binder is required to hold the particle grains together before, when, and after the pellet is dried. The pelletization process is the primary consumer of binders in the iron ore industry. The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price.Web

Abstract. 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 ...Web
