Abstract
    This work is concerned with study the affecting parameters on the recovery of V from pre-processed gibbsite bearing shale sample which assays 0.045% of V which obtained from Abu Thor area, Southwestern Sinai, Egypt. The original sample (0.05 % V) was previously treated to selectively extraction of Cu, Cd and U through applying H2SO4 acid agitation leaching. The present study work involves alkaline dissolution of the sample residue with NaOH solution at the obtained optimum conditions. However ion exchange process was applied by using anion exchange resin, Amberlite IRA743.
     About 97.25% of the extracted V was already regenerated by using 4% H2SO4. Not less than 98.2% of V was precipitated as hydrated V2O5 by using NH4OH solution via strongly oxidation by the addition of 0.25g KClO3 at 75 oC with continuous stirring for 2h. The latter was dried in the oven at 120 oC to prepare the final V product V2O5 (red cake). The overall process was designed in a technical flowsheet.
