摘要：
A process for recovery of vanadium from vanadium slag involving leaching with acid, solvent extraction, precipitation of V2O5 with ammonia, and roasting has been developed. Soaking the raw material in-dilute acid allows over 98% of the vanadium to be directly extracted. Using an accelerant enhances the leaching efficiency compared with the conventional method. The total recovery efficiency of vanadium is above 80%, which is more than 15% higher than that obtained in the conventional process. The new process does not cause air pollution, released by calcination of the raw material.
