Titanium Recovery from Baima Crude Residue

The annual output of Baima crude residue is 1.3 million tons,with average 3.09% of TiO₂ content.At present,the residue is directly discharged into tailing pond,resulting in waste of titanium resources.In order to recover ilmenite from the residue,the combined processes of pre-discarding the tailings by ZCLA,then grinding for iron removal-strong magnetic separation-spiral classification-grinding for iron removal-strong magnetic separation-flotation were carried out in the laboratory.The results show that ilmenite concentrate with the yield rate of 0.47%,TiO₂ grade of 46.06% and recovery rate of 7.18% can be obtained through the combined processes,which provides a technical foundation for ilmenite recovery from Baima crude residue.
