| Abstract: | Extracting of cabalt from cobalt oxide ore has been researched.Using sulfuric acid solution,leaching rate of cobalt can reach to 99% and mass fraction of cobalt in leaching residue can reduce to 0.5% by two stages leaching.From the leaching solution,iron is removed by jarosite method,and calcium and magnesium are removed using sodium fluoride,and copper is removed using sodium sulfite.All impurities can be more removed by P204 multilevel solvent extraction.Colbalt and nickel can be separated by P507 solvent... |
