| Abstract: |
| Studies were conducted on the electrostatic separation tailings of Panzhihua V-Ti-Sc magnetite. The process includes sulfuric acid or caustic fusion or lime proportional to additive roasting. A fairly good way of completely decomposing Ti tailings was found out, then leaching caustic-fusion-roasted residue by 30% HCl, leaching lime-roasted residue by 60% H2SO4, respectively, their maximum leaching rate of scandium was 89.8% and 67.9%, the purpose of decomposing tailings is reached. |
