Titanium Recovery from Baima Crude Residue
-
摘要: 白马粗渣年产量130万t,TiO2平均品位约3.09%,目前直接排入尾矿库,造成资源浪费。在实验室采用ZCLA进行预先抛尾,抛尾精矿采用“磨矿除铁—强磁—螺旋—磨矿除铁—强磁—浮选”流程进行钛回收试验,获得了产率0.47%、TiO2品位46.06%、TiO2回收率7.18%的钛精矿,为白马粗渣钛回收提供了技术依据。Abstract: 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.
