Problems solved by technology

The selected titanium grade of spiral + electric separation is about 25%, and high-voltage ionization above 10,000V is used. This method occupies a small area and has a high titanium recovery rate, but the production cost is high and the investment cost of equipment is high.
Spiral + shaking table titanium concentrate not only consumes a lot of water, has low titanium recovery rate, but also occupies a large area, which is not conducive to long-term development in today's increasingly scarce land resources

Embodiment 1

[0030] TiO obtained by spiral treatment 2 100 tons of spiral concentrate with a content of 37%, 90 tons of the part with a particle size of 0.6-0.074mm is collected through a double-layer high-frequency vibrating screen, dried by a dryer, cooled by a cooler, and then enters the sand blasting drum and iron removal drum, producing 77 tons of TiO 2 Titanium medium ore with a content of 43.5%, after 5 times of dry separation, produces 70 tons of TiO 2 The qualified titanium concentrate with a content of 47% has a titanium recovery rate of 88.92%.

Embodiment 2

[0032] TiO obtained by spiral treatment 2 100 tons of spiral concentrate with a content of 36%, 88 tons of the part with a particle size of 0.6-0.074mm is collected through a double-layer high-frequency vibrating screen, dried by a dryer, cooled by a cooler, and then sent to a sand blasting drum and iron removal drum, producing 75 tons of TiO 2 Titanium medium ore with a content of 43.3%, after 5 times of dry separation, produces 67 tons of TiO 2 The qualified titanium concentrate with a content of 47% has a titanium recovery rate of 87.47%.

Embodiment 3

[0034] TiO obtained by spiral treatment 2 100 tons of spiral concentrate with a content of 35%, 85 tons of the part with a particle size of 0.6-0.074mm is collected through a double-layer high-frequency vibrating screen, dried by a dryer, cooled by a cooler, and then enters the sand blasting drum and iron removal drum, producing 71 tons of TiO 2 Titanium medium ore with a content of 43.2%, after 5 times of dry separation, produces 65 tons of TiO 2The qualified titanium concentrate with a content of 47% has a titanium recovery rate of 87.29%.

[0035] Advantages of the present invention: due to the adoption of double-layer screening, coarse particles and fine particles are separated, greatly improving the sorting quality (TiO 2 Increased by more than 0.3%, concentrate output increased by more than 20%), reduced dust pollution (reduced by more than 70%). The mineral processing cost of the process of the present invention is 130-180 yuan / ton, the mineral processing cost of spi...

Abstract

The invention relates to a coarse fraction ilmenite titanium selecting art, belonging to the ore sieving field. The method comprises following steps: A. concentrating the magnetic tailings, entering into a spiral chute, obtaining a spiral ore concentrate and a helical mine tailing; B. sieving the helical ore concentrate, collecting the part with the graininess of 0.6-0.074 mm, drying, enriching the titanium middling, performing dry type strong magnetic separation, obtaining titanium ore concentrate and ferrotitanium middling. The invention for sieving titanium ore concentrate not only ensures the quality, but also the recovery rate of the titanium ore concentrate. The product quality and the recovery rate are better than the helix as well as shaking table art and the cost is smaller than the helix as well as electrostatic separation art.

Description

technical field [0001] The invention relates to a titanium beneficiation process of coarse-grained ilmenite, belonging to the field of ore screening. Background technique [0002] During the iron separation process of vanadium-titanium magnetite, the magnetic separation tailings produced include coarse-grained ilmenite and fine-grained ilmenite, and the coarse-grained ilmenite is mainly separated by spiral + shaking table, spiral + electric separation Extract titanium concentrate; if fine-grained ilmenite is selected by physical methods such as spiral + shaking table, spiral + electric separation, the effect is poor, and the recovery rate is very low, so flotation process is usually used to select titanium. [0003] The specifications of spiral + shaking table, spiral + electric separation spiral chute are ￠1200mm, height 4.8m, and the separation products are tailings, middle ore and concentrate from the outside and inside. The selected titanium grade of spiral + electric s...
