spiral separator in recovering titanium concentrate - jxsc

spiral separator in recovering titanium concentrate - jxsc

By taking a review of mineral characters and process technology of ilmenite ore, it is necessary to improve the titanium concentration rate and optimizing the mineral processing plant. This is a research paper of using spiral separator to recover titanium concentrate from ilmenite ore, that would be worthy to do it if do a little help for you in the titanium mining.

The metal minerals are mainly ilmenite, secondary of white titanium, anatase, hematite, limonite and a small amount of fine magnetite. Gangue minerals are mainly plagioclase, chlorite and titanaugite. The metal sulfides are mainly of pyrite, traces of chalcopyrite, covelline, magnetic pyrite. Other components have biotite, sericite, swarthy, aragonite, calcite, quartz, apatite, spinel, garnet, titanite, etc. From Table 3, it can be seen that the grain size yield of-0.074 mm and the distribution rate of TiO2 account for more than 40 percent, and the gravity difference between of target minerals and gangue is significant, that is suitable for using spiral chute concentrator of gravity separation. What is the gravity separator machine?

Through observing the distribution of different particle size in the trial experiment, it is preliminarily determined that the grade of crude concentrate is not high. In order to select suited spiral concentrator, four models of the spiral chute with different structural parameters are used for rough separation.

There are four models of spiral separator, QL610 type, QL12AP type, QL12AK type and QL6AK type. The test results show that the QL610 type screw classifier can obtain 25.68% concentrate product with 28.81% of recovery rate, it is suited for rough separation of materials. The concentrate grade and concentrate recovery rate of QL12AP type spiral chute is 16.23% and 35.13% separately; the QL12AK type has a high concentrate recovery rate and low tailings grade. Therefore, the QL12AK spiral chute is the best for rough separation. Spiral separator for sale

2.2.1 Shake table concentration test Adding water to the concentrate ilmenite which obtains from the QL12AK spiral chute, the shake table test result of the slurry as follows. As is shown in table 5, we can obtain the crude ilmenite concentrate products with 33.01% TiO2 grade, yield 6.61%, recovery rate 35.91% through the gravity separation process of QL12AK spiral chute and 6S shaker, from the raw ores with 6.08% TiO2 grade.

2.2.2 Spiral chute concentration test The concentrate products obtained from QL12AK spiral gravity separation machine were fed into three different types of spiral gravity chutes one by one for the selection test. As can be seen from table 6, QL12AK spiral chute is used in both rough selection and selection, we obtain the concentrate titanium with 25.01% grade, yield 9.40%, recovery rate 38.66%. If set the TiO2 28% grade as the target, can be obtained Ti concentrate of grade 29.50%, yield 6.43% and recovery rate 31.20%.

According to microscope observation, there are many sulfide compounds in the shaker titanium concentrate. If the sulfide compounds are sorted out, not only the TiO2 grade of coarse titanium concentrate can be improved, but also the sulfide minerals with a higher grade of S can be recovered. The flotation agent: butyl xanthate 300 g/t, sulfuric acid 300 g/t, 2# oleic acid 60 g/t. Here are two types of raw ilmenite ore processing circuit, one is QL12AK spiral separator, 6S shake table then flotation desulfurization; another is QL12AK both of rough selection and concentrate selection, then flotation desulfurization. the former one has the concentrate titanium of TiO2 38.80%, yield 83.11%, recovery rate 97.69%, and the S for grade 40.03%, yield 16.28% and recovery rate 97.14%. the latter one has the titanium concentrate for 28.35% grade TiO2, yield 85.02%, recovery rate 96.39%, and the S for grade 32.06%, yield 14.98% and recovery rate 81.54%.

Flotation agents: trapping agent 2700 g/t, Roughing sulfuric acid 3000 g/t, concentrate sulfuric acid 800 g/t. According to the titanium processing flow of spiral chute, shaking table, floating sulfur, floating titanium, the ilmenite raw ore 100 t/h can produce the more qualified grade of high titanium ore 3.40 t/h.

It is workable that to recover high titanium ore by floating the tailings which were beneficiated by gravity separation and desulfurization by flotation.
