Description

The recovering of vanadium from Na2SO3-H2SO4 solution obtained from the leaching of spent vanadium catalyst in sulphuric acid production is presented by using solvent extraction with D2EHPA-TBP-kerosene, stripping and oxidation-precipitation. The results showed that the vanadium efficiency of extraction, stripping and oxidation-precipitation was up to 99%, 99.7% and 98% respectively. The obtained product can meet the requirements for export commodities. The tested flowsheet is simple, feasible and suitable for industrial production
