method for recovering vanadium from vanadium

Method for recovering vanadium from residues from the

A method is described for recovering vanadium from residues from the combustion of petroleum fractions, wherein the residues, such as ash and soot, are leached with aqueous H 2 SO 4 to extract vanadium and any additional polyvalent cations contained therein. The acid leaching solution, after oxidation of the extracted cations, is treated with a complexing agent, in particular EDTA or salts

Kinetics of vanadium dissolution from black shale in

Abstract The leaching kinetics of vanadium from black shale in the sulphuric acid–oxygen system is presented. The effects of agitation speed, leaching temperature in the range of 110–150 C, sulphuric acid concentration, oxygen partial pressure and particle size on the rate of vanadium leaching were determined. The results indicate that the rate is nearly independent of agitation above
