FeO determination in rocks and minerals by wet chemistry

FeO determination in rocks and minerals by wet chemistry Introduction Most analytical techniques used for rocks and minerals cannot distinguish between the 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 Fe 2+and Fe3+states, usually present in minerals as the ...

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 ...

Theory and Practice of Sintering of Iron ore – IspatGuru

2018-11-25  In an another study it has been found that the softening temperature comes down as the gangue content in the ore increases, due to the fact that gangue forms compounds with low melting point such as 2FeOSiO2, FeOSiO2CaO, and Fe2O3SiO2CaO (Fig 5). The alkalis contained in gangue can also form compounds with a low melting point such as Na2SiO3, K2SiO3, and
