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 …

15.1. Introduction. 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.

This paper summarizes the data of pellet studies conducted by Torex LLC in the period 2014–2022 and partially published in [12–14]. In particular, a comparison was made of the analysis of the pellets structure from magnetite concentrates with a SiO 2 content of 2.5–4.0% (sample 1), 4.5–6.0% (sample 2) and 6.5–8.3% (sample 3) in the …

The degrading iron ore quality and environmental norms has forced sinter producers to look for additives which can improve the sintering process efficiency. For the current work, use of calcined colemanite as an additive was studied by adding it from 0% to 4% within the sinter raw blend through lab-scale pot trials.

Before iron ore can be used in steel production, it often undergoes an additional step called pelletization or sintering. Pelletization involves forming small balls or pellets by agglomerating the fine iron ore particles with a binder, such as bentonite clay.

This process of converting iron ore into pellets is known as Pelletization. Iron Ore Pellets are then used in the production of steel. Pellets are usually preferred instead of raw Iron Ore because it allows for maximum utilization of iron ore. This is important since iron ore reserves are depleting globally.

ABSTRACT. The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the inter-particle bonding within the pellet.

The iron ore fines with less than 10 mm size are usually fed to the sintering process, and only limited fraction (less than 20%) of − 150 micron size of iron ore fines are allowed in the sintering process. The finer sized iron ore may choke the sinter bed and hinder the uniform air suction through the bed.
