Influence of Iron Ore Characteristics on FeO Formation

The results indicate that LOI (loss on ignition) in iron ores have a positive influence on FeO formation by promoting the sintering process of Fe 2 O 3 decomposing and reducing. Silica contents in iron ores play a determining role in final content of FeO in sinter.

Recrystallization of Fe O During the Induration of Iron

The FeO content in pellets with H/M=70:30 under different preheating conditions were analyzed and are shown in Fig. 3. FeO content falls gradually with the increase in preheating temperature and time. FeO conten t is less than 3% only if the preheating time is more than 11 min at 850 qC; however, at 900 qC, FeO content goes down to

Effect of FeO Content in Ore on the Properties of Sinter

The content and stability of FeO in sinter are the important comprehensive indicators to assessing the sintering production. They not only reflect the quality and energy consumption of agglomerates, but also influence the smelting results of blast furnace. The effects of the FeO content of original ores on the FeO content in sinter and the creating ability of calcium ferrite are discussed in

FeO determination in rocks and minerals by wet chemistry

oxidation states of different chemical elements, including iron. Because of its abundance, the redox state of iron can be particularly important. The iron in common rocks is in the Fe2+and Fe3+states, usually present in minerals as the nominal chemical components FeO and Fe 2 O 3, respectively.

Influence of Basicity and FeO Content on Viscosity of Blast

FeO. Since the reduction of iron ores and the formation of slags with coke/coal ash proceed in the BF, basicity (CaO/SiO 2) and FeO content in slags continuously change from the composition of initial sintered ore. Because the slags do not fully assimilate with ash in the bosh region of the blast furnace, they exhibit relatively high CaO/SiO 2

Goethite Wikipedia

Composition. Goethite is an iron oxyhydroxide containing ferric iron. It is the main component of rust and bog iron ore. Goethite's hardness ranges from 5.0 to 5.5 on the Mohs Scale, and its specific gravity varies from 3.3 to 4.3. The mineral forms prismatic needle-like crystals ("needle iron ore") but is more typically massive.. Feroxyhyte and lepidocrocite are both polymorphs of the iron

Maximizing Iron Unit Yield from Ore to Liquid Steel (Part

Higher slag volumes or higher FeO content of the slag will lead to higher iron in the slag. This is not unreduced oxide from the DRI product and is completely independent of metallization and DRI carbon content. This is the equilibrium (or dis- equilibrium) of the slag with the oxidation state of
