Embodiment

[0060] to TiO 2 The total tailings with a grade of 3.83% are classified with a 60-mesh sieve; 2 Grade 2.35%, under-sieve -0.35mm particle size TiO 2 Grade 4.57%;

[0061] +0.35mm particle size is pre-enriched by ZCLA separator, the ore concentration is 50%, the magnetic field strength is 8500Gs, and TiO can be obtained 2 Grade 5.85% coarse concentrate; -0.35mm particle size ZH combined magnetic separator feed concentration is 35%, magnetic field strength is 8500Gs, TiO can be obtained 2 Grade 6.61% rough concentrate;

[0062] The mixed concentrate of ZCLA concentrator and ZH combined magnetic separator enters the ball mill and grinds to -200 mesh, accounting for 91%;

[0063] Grinding products adopt ZH combined magnetic separator with one coarse and one fine separation, the ore concentration is 35%, the medium flushing water pressure is 0.3MPa, the rough separation and concentration adopt the magnetic field strength of 8000Gs and 10000Gs respectively, and TiO can be obtain...

Abstract

The invention belongs to the technical field of mineral processing, and particularly relates to a method for recycling micro-particle ilmenite through vanadium-titanium magnetite titanium beneficiation main tailings. For the problems that in the prior art, the micro-particle yield of micro-particle-level ilmenite in vanadium-titanium magnetite titanium beneficiation main tailings is large, and themicro-particle-level TiO2 distribution rate is high, according to the technical scheme of the method, classifying equipment is adopted for classifying the vanadium-titanium magnetite titanium beneficiation main tailings, a ZCLA concentrating machine is adopted for enrichment for the coarse fraction, a ZH combined magnetic separator is adopted for enrichment for the fine fraction, and after concentrates of two devices enter a ball mill for ore grinding, the ZH combined magnetic separator is adopted for one roughening and one refining, ZH concentrates with the TiO2 grade larger than 18% are obtained, then preselection desulfuration and one-roughening, four-refining and one-sweeping refining are conducted, and titanium concentrates with the TiO2 grade larger than 47% are obtained.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to a method for recovering fine-grained ilmenite from vanadium-titanium magnetite beneficiation total tailings. Background technique [0002] In the Panxi vanadium-titanium magnetite ore, apart from iron, there are strategically important metals such as titanium, vanadium, chromium, cobalt, nickel, etc., and their content mostly reaches the industrial index of comprehensive utilization, and the recovery value is very high. By the end of 2007, the proven ore reserves of the four major mining areas and surrounding mining areas reached 10.1 billion tons, and the predicted prospect resources amounted to more than 19.452 billion tons. Iron ore reserves rank second among the country's four major iron ore mining areas (Anben, Panxi, Hebei, and Wulan). Titanium and vanadium reserves account for more than 90% and 62% of the country's total respectively, and the prospec...
