Iron ore pellets are small and hard spherical particles agglomerated from a fine iron ore concentrate. They are used in the blast furnace process to produce hot metal. The diameter of blast furnace pellets is usually between 8 and 16 mm. In this study, a batch of magnesia iron ore pellets was first sieved into particle sizes of 8–10 mm, 10–12.7 mm, 12.7–16 …

Iron ore lump, sinter, and pellets comprise the main burden of modern blast furnaces. However, sinter and pellets are now the dominant blast furnace burden, because the natural lump supply has declined dramatically due to depletion of the world's high-grade competent iron ore resources. In addition, more iron ore concentrates are being ...

The sinter plant that converts the iron ore fines into a desirable blast furnace feed, offers an avenue for recycling wastes. One of the several wastes that are produced at an iron and steel plant is the undersized pellet fines, which cannot be directly used in iron making. The present study evaluated the influence of these pellet fines on the sintering process. 5 …

4.2.2 Sinter. Low-temperature (< 1300 °C) iron ore sinter is an agglomerate of unmelted and partially melted nuclei particles (+ 1 mm) and a matrix bonding phase produced from the melting of fine ore (− 1 mm) and flux particles, with the majority of melt formation occurring in the granule adhering fines layer. The majority of nuclei are hematitic, but they can also be any other …
