In view of the present situation that the existing industrial technology for vanadium precipitation is not suitable for the carbonated leachate of vanadium slag with high content of calcium and phosphorus,the process of precipitating vanadium by ammonium carbonate ((NH4)2CO3) was adopted for that leachate. The residue washing water in leaching process was mixed with the washing water for vanadium precipitation,concentrated by evaporation and then mixed with the upper-liquor of precipitating vanadium for the reuse as leaching agent. The results show that after 5 times of recycling every component of the obtained product meets the industry standard with more than 99% vanadium pentoxide (V2O5). It realized the recycle of waste water.
