| titleOfInvention | Method for recovering titanium from titanium-selecting tailings of vanadium titano-magnetite |
| abstract | The invention discloses a method for recovering titanium from titanium-selecting tailings of vanadium titano-magnetite, which comprises the steps of mixing the titanium-selecting tailings into ore pulp, screening, and grading screened products into first settled sand and first overflow; performing secondary classification on the ground first settled sand into second settled sand and second overflow; carrying out first low-intensity magnetic separation on the second overflow to obtain first iron ore concentrate and first magnetic tailings; carrying out magnetic separation on the first magnetic separation tailings to obtain second tailings and second magnetic separation concentrates; carrying out second low-intensity magnetic separation on the first overflow to obtain second iron ore concentrate and second magnetic tailings; carrying out magnetic separation on the second magnetic separation tailings to obtain third tailings and first magnetic separation concentrates; grinding the first magnetic concentrate and the second magnetic concentrate, and then carrying out low intensity magnetic separation to obtain a third iron concentrate and a third magnetic tailings; carrying out magnetic separation on the third magnetic separation tailings to obtain primary titanium concentrate and fourth tailings; and carrying out flotation and scavenging on the primary titanium concentrate to obtain the final concentrate. Solves the problem that the fine ilmenite is difficult to recover in the prior art. |
