[0037] Example 1
[0038] Such as figure 2 As shown, a process method for improving the quality of vanadium-titanium iron concentrate includes the following steps:
[0039] (1) The second-stage coarse iron concentrate is lifted and transported to the third-stage screening equipment for pre-classification by a slurry pump. The under-screen material enters the three-stage coarse magnetic separation, and the over-screen material is pumped to the three-stage mill. Magnetic separation and concentration by the former magnetic separator.
[0040] Specifically, the raw vanadium-titanium magnetite ore is crushed in three stages, namely, one open-circuit coarse crushing, one open-circuit crushing, and one closed-circuit cycle fine crushing. The raw ore is crushed to -10mm≥90%, and then wet pre-sorting is performed. The ore enters the sieving operation, the oversieve enters the first stage of grinding, and the undersieve enters the first stage of magnetic separation operation; the first stag...
