For sinters, ongoing studies have identified differences according to different blend compositions and also differences between sinter size fractions, to be discussed later. Fig. 3.7 shows the differences between different clusters of sinter samples as small spheres of different colors. The biggest differences between samples are manifestedFurthermore, at 10 pct contraction, a pseudo-globular wüstite structure interspersed with slag was observed for the pellet and sinter cores. At 50 pct contraction, the previous structure coalesced to form a globular shape wüstite in a well-connected slag matrix. self-fluxed pellet, and sinter.

The use of high basicity sinter with high-silica fluxed pellet is the direction of development of high proportion pellets suitable for our resource characteristics [9,10]. Many scholars have studied the differences between acid and fluxed pellets, and softening-melting behavior of high proportion pellets in blast furnace.study. Jagannath found that there was only a tiny difference between the metallurgical performances of limestone fluxed pellet and calcium lime fluxed pellet with basicity of 0.2.18) The hydrated lime may be more suitable for preparation of basic pellets as it can provide abundant CaO in the indura-Utilization of Hydrated Lime as Binder and Fluxing Agent

Sinter fines and lumps make up the bulk of the seaborne iron ore market, and are the products most frequently traded on a spot basis, so daily pricing is used for the key 62% Fe, 58% Fe and 65% Fe fines, and lump premium references. By contrast, the beneficiated ore segment comprising pellet and concentrate is smaller in terms of sinter, 20% lump ore, and 15% pellets is found to have the best results (Hsieh and Liu 1998 ).

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, The lump ore from Azul (47.7% in the overall sample) and the pellets (50.9%) have a manganese content considered good for the process. The difference in manganese content reaches 3.2%. The lump ore from Azul has a Mn/Fe ratio of 13.3, while that of the pellets is 6.8.A geometallurgical comparison between lump ore and pellets
