FerrovanadiumTxoj kev smelting - thermite method. Aluminium yog siv los ua tus neeg sawv cev txo qis, thiab cov txheej txheem hluav taws xob hauv qab yog siv rau smelting nyob rau hauv lub cub tawg chim lined nrog ib tug alkaline rauv. Ua ntej muab ib feem me me ntawm cov nqi sib xyaw rau hauv lub reactor thiab ignite nws. Tom qab cov tshuaj tiv thaiv pib, ntxiv qhov seem ntawm tus nqi ib zaug. Nws feem ntau yog siv los smelt siab vanadium hlau (muaj 60 ~ 80% vanadium). Tus nqi rov qab yog me ntsis qis dua li ntawm txoj kev electrosilicothermal, txog 90 ~ 95%.
Feem ntau siv ferrovanadium muaj 40%, 60% thiab 80% vanadium. Lub ntsiab raw khoom rau Tuam Tshoj ferrovanadium ntau lawm yog vanadium-titanium magnetite. Tom qab tau txais txiaj ntsig thiab kev nplua nuj, vanadium-muaj cov npua hlau yog smelted los ntawm lub qhov cub tawg, thiab vanadium slag yog muab rho tawm thaum lub sij hawm atomizing rauv los yog converter tshuab.
Tom qab lub vanadium slag yog crushed, sodium ntsev (soda tshauv, rooj ntsev los yog anhydrous Glauber's ntsev) yog ntxiv rau sodium oxidation roasting tig lub vanadium rau soluble sodium metavanadate (NaVO3). Tom qab leaching thiab purification, ammonium sulfate yog ntxiv rau precipitate polyvanadate.
Ammonium [(NH4) 2V6O16] yog tom qab ntawd yaj los ntawm deamination thiab muab pov rau hauv flake-shaped vanadium pentoxide. Cov khoom xyaw uas xav tau yog V2O597 ~ 99%, P<0.05%, S<0.05%, Na2O+K2O<1.5%. In addition, vanadium pentoxide is also extracted directly from vanadium-containing iron concentrate or vanadium-containing carbonaceous shale through chemical treatment.
