1.2.2.2.1.3 Pelletizing Technologies There are two main types of pelletizer that are used to produce iron ore pellets at industrial scale, the rotary drum and the disc. Besides iron ore agglomeration, these pelletizers can also be used for other materials such as copper ore, gold ore, coal...
Use of Hot Briquetted Iron Made From Low-Grade Iron Ore Pellets in a Blast FurnaceDRIHBIAlternate ironBFIron oxide pelletsIron oxide pellet specifications for direct reduction require gangue levels considerably less than typical blast furnace pellets. This restriction is due to the needs of the ...
All iron ore that is mined has to be crushed, and if the particles are of suitable size are directly charged to a blast furnace; however, if the particles are too fine, then they are processed in a sinter or pellet plant prior to introduction in a blast furnace (Walker, 1986). ...
While Sweden is one of Europe’s largest iron-ore-producing nations, with 12 active mines, H2 Green Steel is still in discussions with local mining companies to supply ore according to its pellet specifications. And while the rail network connecting Swedish mines passes by Boden, available logist...

S&P Global [Commodity Insights] has broadened its coverage of iron ore ever since its inception, going beyond 62% Fe materials to lump, pellet and pork stock pricing. The market needs transparency and I think that S&P Global [Commodity Insights] can help to promote this ...
The relative fineness of an iron ore pelletizing feed may be derived from its specific surface. However, the Blaine Number calculated from air permeability data according to ASTM specifications relies on the presumption that the particle...

low gangue lump from Australia – enables higher hot metal production and lower energy requirements in the blast furnace. The direct charge into the blast furnace also avoids costs and emissions associated with sintering and pelletising processes. Sintering is a highly air polluting activity that is...
Induration is a crucial step in pellet making process in the steel industry. This unit is well-known as an energy intensive process [6] and motivated with this fact, the present work is undertaken to deal with this iron ore pellet induration system. The induration units used for heat hardeni...
