Effect of Calcium on the Vanadium Extraction from High Calcium Type Stone Coal包申旭1,2,LIANG Liang1,张一敏1,2,HAN Shihua1,HU Yangjia11. College of Resources and Environmental Engineering, Wuhan University... by water and dilute acid separately after being roasted with different dosage of Na Cl. The water leaching rate of vanadium(WLRV) was low and only 26.8% of vanadium can be leached by water when 4% Na Cl......
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......
