About the Sampling Test:
An sampling experiment has been conducted on the beneficiation process to study the scientific and rational process, comprehensively to recycle the ferrotitanium resources lost in the tailings.According to the results of the original ore mining in combination with existing beneficiation process, such selection process by weak magnetic-strong magnetic- gravitional has been carried out together with detailed conditional tests and full-process tests , obtaining very good technical indicators . One step of the rational utilization of the titanium tailings resources provides a technical basis.
For this sample, two experiments were investigated in this experiment. Process 1 is a weak magnetic-strong magnetic-centrifuge combined process, which can obtain a titanium concentrate with a TiO2 grade of 36.08% and a recovery rate of 20.89%.
According to the needs of the site, if it is necessary to continue to improve the grade of titanium concentrate, then process 2 can be used, and process 2 is a weak magnetic-strong magnetic-centrifuge-shaker combined process, which can obtain titanium with a TiO2 grade of 45.12% and a recovery rate of 18.08%.
Original Mineral Composition
The main metal mineral in the ore is ilmenite, and there are small and trace amounts of magnetite and leucox. The ilmenite is mainly in the form of crystal grains, and the particle size is fine, generally less than 0.05 mm, and the smallest is 0.001 mm.
Titanium is mainly produced in the form of ilmenite, followed by leucite. Most of them exist in the form of monomers. The edges and cracks of a small amount of ilmenite are etched into leucosite. The ettringite chemical formula TiO2·nH2O, TiO2, leuco is not an independent mineral, it is a cryptocrystalline anatase mineral. Rutile, brookite, hematite
(Occasionally there is a mixture of vermiculite) (Photo 1), part of the titanium mineral and magnetite are solid solution separation structure, forming a sheet-like crystal (photo 2), the two are more difficult to dissociate, occasionally pyrite and titanium Iron ore is adjacent to continuous life, and the intercalation relationship between other minerals is not close.
These two options are technically feasible.
4. After the industrial construction according to the recommended procedure, the annual profit will be 7.3801 million yuan, which is economically feasible.
5. The program obtained in this test is technically feasible, economically feasible, and can achieve high economic benefits. It is recommended to implement it as soon as possible.
