The preparation of high-purity ammonium metavanadate from impure vanadium pentoxide by precipitation with ammonium chloride: M34-20/64E-PDF

“High-purity ammonium metavanadate can be obtained as a precipitate when the filtered solutions from the leaching of crude vanadium pentoxide are treated with ammonium chloride. The effect of using an excess of sodium carbonate, as a leaching agent, on the rate of leaching of vanadium pentoxide has been qualitatively investigated, and the effects of excess sodium carbonate, and of the concentration of vanadium pentoxide in the leach liquor on the efficiency of precipitation with ammonium chloride have been quantitatively determined. Data are given showing the results obtained when both pure and crude vanadium pentoxides are treated in this way. Conditions are specified which result in the dissolution of 97% of the vanadium from crude vanadium pentoxide, and in the precipitation of 99% of the dissolved vanadium as ammonium metavanadate of high purity"--Abstract, p. i.
