The process of making pellets from iron ore is called pelletizing. ... During the process of pelletizing, the non-agglomerated iron ores are mixed together with the additives. The ratio of mixing depends on the quality of the pellets and the quality of the sinter fines. The mixture is then molded in the form of round pellets.
Iron ore lump and sinter fines are examples of DSOs, which are mined predominantly from areas ... Only a few producers can supply iron ore pellets and rarely lump grades upward of 66-67 Fe suitable for the DR route. Iron ores that can ... as sintering where they are agglomerated into crude pellets called sinter. This step is
Simultaneously, iron ore fines are agglomerated into sinter and pellets through the sinter and pellet plants, respectively, and iron ore lumps are reduced to DRI in the sponge iron kilns. The sinter, pellets, metallurgical coal and quartzite are fed into the blast furnace where the mixture, through a reaction with preheated air, is reduced into ...

Sinter, lump ore, and iron ore pellets were used in experiments. The composition for all three materials is shown in Table 1.
There are three major iron sources pellets, sinter, and iron ore. Metallurgical coke is used as the fuel and reducing agent in the blast furnace process. Coke is the product of carbonization or distillation of mainly bituminous coal. Flux is also added to the blast furnace charge to absorb impurities present in the iron sources and coke ash.
2.2 Comparing Sinter and Pellets Sinter and pellets are agglomerated forms of iron ore, both suitable for use as blast furnace burden materials. The principle difference between sinter and pellets arises from the type of raw materials used in their preparation and the nature of the sinter and pelletizing agglomeration processes.
