Abstract

In connection with recent analyses of Taranaki ironsand, it was suggested that a simpler analytical separation of iron and vanadium might be found than the method in use, namely fusion with a flux consisting of a mixture of sodium and potassium carbonates. This method is tedious because of the two or three fusions which are necessary, the amount of time consumed and the uncertainty that all the vanadium has been extracted. Accordingly, in this work several methods of separation have been tried including fusion, precipitation and distillation methods. Many methods are available for the estimation of iron and vanadium in the presence of each other. These are chiefly reduction - oxidation processes in which ferric iron is reduced to ferrous and the vanadium from v5 to V4 or V2, with subsequent oxidation.
