include iron scrap, reduced iron pellets and reduced iron briquettes. Sintered ore is made by partially melting and sintering coarse iron ore 1 to 3mm in size into products having a size of 15 to 30mm. The sintering process uses the combustion heat of coke breeze (fuel). Pellets are made from iron ore that is finer

The pelletizing process, where the crude ore from the mine is upgraded, involves several steps, including grinding, balling, and induration; see Figure 1 to the left. In the gratekiln induration process []—see Figure 1 to the right—the sintering is mainly taking place in a rotary kiln, where the pellets increase their strength and metallurgical properties.

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. Binders accomplish two very important functions in iron ore pelletization: •.

In general, pelletization of iron ore is a process where the feed is a mixture of highgrade hematite/magnetite ore mixed with binder and coke breeze as additives to form pellets for the production of iron and steel [5]. Such types of initiatives can eradicate the crises of highgrade iron ore demand as pellet feed material as well as support ...

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 experiments were conducted ...

Abstract Iron ore, pellets, and sinter were reduced with hydrogen at 800 °C to understand the degree of reduction and the mineralogical aspects. The weight loss of goethite and limonite iron ore was noticed to be lower than that of magnetite and hematite varieties. Xray diffractometry (XRD) indicated 100 pct Fe in the case of hematite, 93 pct in magnetite, 53 pct in goethite, and as low as ...
