Vanadio a partir de los residuos de combustión de coque de petróleo. Precipitación

Abstract

Different proccesses to precipitate Vanadium from solutions gotten by H2SO4 leaching of combustion residues of Venezuelan fuel oil cocke are tried. Using NaClO4, it is recovered 85% of vanadium as V2O4 and Fe, Ni and V sulphates. Using NaOH and NaClO4, it is recovered 20% of vanadium as Na3V04.16H2O Using HClO4, it is recovered 60% of vanadium as impure V2O5.
