the intermediate product during the previous vanadium-chromium co-extraction by vanadium slag sub-molten salt process
to vanadium oxide using calcification and carbonization-ammonium method was proposed. The calcification of sodium vanadate
carbonization-ammonium of calcium vanadate
and cooling crystallization of ammonium vanadate were systematically studied. The results showed that vanadium oxide prepared by sodium vanadate can be realized by calcification and carbonization-ammonium method. Vanadium recovery rate can arrive at 96.99% and the purity of product V2O5 over 98.53% (mass fraction). The production of high salt ammonia nitrogen wastewater was avoided from source
