| Abstract: | An optimum method for recovering the titanium and aluminium from titanium-iron slag has been described in the paper. The conditions of acidolysis with sulphuric acid and leaching wiht water have been studied. The separation of titanium and aluminium is attained by solvent extraction.Through washing and stripping, finally the titanium are recovered with a form of titanium pigment which purity is over 98%. The recovery rate of titanium is about 93%. |
