RECOVERY OF VANADIUM VALUES |
摘要 |
<p>RECOVERY OF VANADIUM VALUES Vanadium values such as those in the form of vanadium pentoxide may be recovered from vanadium-containing materials by leaching the vanadiumcontaining material with caustic and thereafter precipitating insoluble salts of vanadium with an ammonium-containing compound followed by separation and recovery. After suitable stripping of ammonia from the lean leach solution, said solution may be recycled to the leach step. The recovery of the vanadium values is enhanced by effecting the precipitation step in the presence of carbon dioxide which maintains the pH of the solution in the optimum range.</p> |
