JOURNAL FREE ACCESSThe chemical analysis has been used to assay iron ore. In the routine analysis of iron ores containing magnetite, ferrous, and ferric oxides, percentages by weight of Fe++ and Fe+++ are given as the sum of the percentages of Fe++ and Fe+++ in each component. Therefore we can't obtain the percentages of each component separately by chemical analysis. If any one component be determined by any other method, it is possible to calculate the remaining two components.
In this report, magnetite was determined independently by the magnetic measurement and ferric and ferrous oxides were calculated. It was ascertained by chemical analysis that there exists no magnetic substance such as reduced metallic iron. It is also possible to determine the reduced metallic iron by magnetic measurement. It is a necessary condition in this case that the sample does not contain any other magnetic substance, for example, magnetite, but the ore containing the reduced metallic iron had no Fe++, and the existence of magnetite was not recognized. In conclusion, when we use both magnetic and chemical analysis, we can determine ferrous oxide, magnetite, ferric oxide and the reduced metallic iron in the study of mechanism of reducing reaction of iron ores.View full abstractDownload PDF (1286K) -
