It is shown that the interference of uranium (IV) in the determination of iron (II) in minerals and ores could be removed by dissolution of the sample in phosphoric acid in the presence of which ferric iron is not reduced by uranium (IV). The ferrous iron can then be determined by titrating with standard potassium permanganate using methylene blue as indicator. The results obtained with various synthetic mixtures containing iron (II), iron (III), and uranium (IV) are presented. If uranium (VI) is present in a mineral, it interferes in the determination of iron (II) as it alters the ferrous iron content during dissolution itself. (auth)
