the precipitate formed in the waste water after vanadium removal from raw TiCl4 with copper-wire. The recovery process consists of five major procedures, namely, the self-oxidization of precipitate, the removal of chlorine with sodium hydroxide solution, the first-stage leaching of copper with sulphuric acid and recovering vanadium by roasting the first leached residue with sodium carbonate......
