Study on Extraction of Vanadium from High Acid Leach Solution of Stone Coal Using Extractant HBL@101

Article Preview

Abstract:

A new extractant HBL@101 was used to directly extract vanadium from high acid leach solution of stone coal. The effects of acidity and Eh of feed, time, phase ratio and temperature on the extraction of vanadium were investigated. The extraction distribution isotherm was also obtained. The results showed that the extraction of vanadium reached 98% in single stage with A/O ratio of 1:1 at 35~45 °C for 10 min. More than 99.7% of vanadium can be extracted in three-stage counter current extraction. The loaded organic can be easily stripped using NaOH solution. After pH adjustment, the strip liquor was used to precipitate vanadium by adding NH4Cl. The final product of V2O5 with purity of 98.7% can be obtained.
