Determination of iron oxides (Fe_2O_3, FeO, Fe_3O_4) in their mixtures by chemical method

摘要

Quantitative determination of iron contents at different level of oxidation is an important problem ifn ferrous metallurgy. It is particularly important in determing the level of iron reduction in sinters, ores and others conglomerates. The paper presents the results of iron oxide dissolution process for different solvents and gives suggested way of chemical analysis procedure, which aims at determining iron at different oxidation levels.
