Titanium, niobium, and tantalum were determined after separation from cobalt and tungsten, without separation from each other. The initial hydrous oxide precipitate was dissolved in dilute hydrofluoric acid and the three desired elements were re-precipitated by cupferron at pH 3.5. The cupferron precipitate was ignited and the oxide residue was weighed and then fused with potassium bisulfate and dissolved in dilute sulfuric acid with hydrogen peroxide present. Titanium and niobium were determined by successive aliquots of the resulting solution; tantalum was calculated by difference. Results are presented in tabular form. (L.N.N.)
