Paper Title:
Processing the Precipitate and Waste Water Formed in Refining Crude TiCl4
  Abstract

The recovery of vanadium and copper from the precipitate and the waste water formed in the removing vanadium from crude TiCl4 with copper wire was investigated. For the processing of the precipitate, the brief flow includes dechlorinating, H2SO4 leaching copper, crystallization blue vitriod, as well as NaOH leaching vanadium, followed by ion exchange enrichment vanadium; the copper and vanadium leaching percent was 88.4% and 84.3%, respectively. For the processing of the waste water, the coprecipitation process was used, after that the discharged wastewater could meet with the National Standards. The precipitate formed in coprecipitation process was first leached by NaOH solution for recovery of vanadium, and then the leach cake containing copper was leached by H2SO4 solution for recovery of copper; the overall vanadium and copper recovery was 79.5% and 86.8%, respectively.
