L. Lu, O. Ishiyama, in Iron Ore. 14.5 Conclusions. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Compared with pellets, production of sinter is cheaper, and compared with lump ore, fluxed sinter is often more reducible with better softening characteristics.Cold briquetting of iron ore fines for DRI ,To overcome this, agglomeration of high grade iron ore fines is done to serve as blast furnace burden.

PiñuelaNoval, Luis FelipeVerdeja. Published 20 December . Materials Science. Iron Ores and Iron Oxide Materials. Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm.
In a reduction roasting process the nonmagnetic iron is converted into magnetite (Fe 3 O 4), or maghemite (γFe 2 O 3). Ore fines of 0–3 mm were treated with coal (10, 15, and 20%) at different temperature (500–750 °C) and passed through the low intensity magnetic separator (0.2–0.3 Tesla). The iron present in the form of hematiteCurrent News of Primetals Technologies Primetals ,Currently, all available technologies require agglomeration, like pelletizing to produce DRI or HBI. An additional challenge steel producers face, is the reduced quality of iron ore, resulting in the need to beneficiate the iron ores. In order to progress to a CO2free steel production, a process using mainly H2 is most desirable.A Process Intensification Approach to Improve ,Process Intensification (PI) is a rapidly growing field of research aiming to improve productivity, accelerate the process with higher reaction rates innovatively, improve efficiency, safety, and reduce emissions to fulfill Environmental Social, and Governance (ESG) commitments. The PI approach is also a pathfinding tool to achieve carbon
The process of compressing or shaping a substance (mineral) into the shape of a pellet is known as Mineral beneficiation, including pelletisation. Pellets are made from various sources, including chemicals, iron ore, animal compound feed, polymers, waste materials, and others. The method is considered a practical choice for storing andAgglomeration metallurgy Britannica,Other articles where agglomeration is discussed: iron processing: Crushing: Fines, however, must first be agglomerated, which means reforming them into lumps of suitable size by a process called sintering.Innovative Development on Agglomeration of Iron Ore ,In steel industry and in mines, a significant amount of ultrafines waste iron oxides and iron ore fines is generated. Utilizations of these fines are required to reduce the environmental hazards and conserve the natural resources. Some of these fines are normally used in sintering practice.
Iron ore concentrate is an output product from processed iron ores that have been milled (crush, grind, magnetic separation, flotation) to separate deleterious elements and produce a highquality product.
