However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process.

Industrial iron ore green pellets are over-saturated and a supporting network of viscous liquid is formed on the green-pellet surface . The strength of this network is initially controlled by the viscosity of the liquid phase.Iron Ore Pellets and Pelletization Process – IspatGuru. Nov 26, 2014 Iron Ore Pellets and Pelletization Process. Pellets plants are normally integrated with the iron ore beneficiation plants. In case they are not integrated then concentrated iron ore in slurry form is usually pumped to the pellet plant by slurry pipelines.
Iron ore pelletizing434 Кб. 2 Iron ore pelletizing Process flexibility There are two main processes for producing iron ore pellets The Grate-Kiln system and the straight grate system.Pelletization process Pelletization is comprised of two main stages (1) agglomeration and (2) induration.Five iron ore agglomeration technologies can be defined briquetting, nodulization, extrusion, pelletization and sintering. Sintering and pelletization are the most important agglomeration technologies, in this way, in the EU-27, 14 countries operate 34 iron ore sinter plants with 63 iron ore sinter strands, producing in the first decade of the.Dec 20, 2017 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. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration.
