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 fine-grained titanium concentrate from the total tailings of vanadium-titanium-magnetite in the technical field of ore dressing, comprising the following steps: firstly, a trommel is used for impurity treatment, and the target object is passed through a cyclone The non-grinding target minerals are separated by the group, and then the non-magnetic gangue minerals in the undissociated minerals entering the ball mill and most of the dissociated materials after ball milling are separated by the method of "screening-ball milling-screening". Pre-throwing, combined with two-stage strong magnetic + screening system at the same time, the valuable materials in the pre-throwing materials are recovered again, and finally through the spiral chute, arc surface spreading flow film sorting and rotary vibration sorting process Obtain fine-grained titanium concentrate. The whole set of process only adopts physical gravity separation, which is a purely green and environmentally friendly way to recover the fine-grained titanium concentrate in the total tailings of vanadium-titanium magnetite, which not only avoids the complicated flotation process, but also avoids the impact of flotation agents on the environment. impact, while reducing production costs.
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 exceed 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 of tai...
