Embodiment 1
[0047] TiO 2 The total tailings with a grade of 5.68% pass through a trommel screen with a mesh size of 1.5mm to remove +1.5mm trash materials, and the -1.5mm titanium selection raw materials pass through the cyclone group to produce an overflow accounting for 35% of the -1.5mm titanium selection raw materials Materials and sandy materials accounting for 65% of -1.5mm selected titanium materials;
[0048] Pass the grit material through the auxiliary vibrating sieve with a mesh size of 0.18mm, and the +0.18mm particle size TiO on the sieve 2 Grade 3.89%, under-sieve -0.18mm particle size TiO 2 The grade is 6.73%, and TiO is obtained by sweeping the +0.18mm particle size material on the sieve through a wet magnetic separator with a magnetic field strength of 11500GS 2 Magnetic material with a grade of 6.68%;
[0049] Put the -0.18mm material under the sieve and the magnetic material obtained by magnetic separation and sweep into the ball mill for grinding according to the con...

Abstract
The invention discloses a method for recovering micro-fine-fraction titanium concentrate from vanadium titano-magnetite total tailings in the technical field of mineral separation. The method comprises the following steps that firstly, a rotary screen is adopted for impurity throwing treatment, and target objects are used for separating non-grinding target minerals through a cyclone set; then, a screening-ball milling-screening manner is adopted for pre-removing non-magnetic gangue minerals in non-dissociated minerals entering ball milling and most dissociated materials obtained after ball milling discharging in a throwing manner, and meanwhile, a two-section strong magnetism and screening system is used in cooperation for recovering valuable materials still in the pre-removed materials again; and finally, the micro-fine-fraction titanium concentrate is obtained through a spiral chute, arc face spreading flow film sorting and rotary vibration sorting technologies. According to the whole technology, only physical gravity separation is adopted, the micro-fine-fraction titanium concentrate in the vanadium titano-magnetite total tailings is recovered in a purely environment-friendly manner, the complex flotation process is avoided, influences of flotation reagents on the environment are avoided, and meanwhile the production cost of enterprises can be reduced.
Description
technical field [0001] The invention relates to the technical field of beneficiation, in particular to a method for recovering fine-grained titanium concentrate from vanadium-titanium magnetite total tailings. Background technique [0002] Panzhihua is the main ore-forming belt of vanadium-titanium magnetite in my country, which contains extremely rich vanadium-titanium magnetite resources, and is also one of the important producing areas of similar deposits in the world. From south to north, it is mainly composed of three mining areas: Panzhihua, Hongge and Baima. The reserves of vanadium-titanium magnetite are more than 7 billion tons. After nearly 50 years of resource development, a huge amount of solid waste has been produced, among which tailings are one of the important solid wastes. According to incomplete statistics, a total of 52 large and small tailing ponds have been formed in the development of resources in the three major mining areas, and the cumulative stock...
