1. Rov qab los ntawm Vanadium Slingag: Vanadium slag yog cov khoom siv raw nrog cov ntsiab lus vanadium, thiab kev rov ua haujlwm rov qab yog cov paub tab. Cov txheej txheem tam sim no yog sodium roasting txheej txheem. Cov khoom siv sib txawv yog siv: Cov chaw lag luam loj feem ntau siv cov tshuaj ntsuab, thaum muaj qee qhov kev lag luam siv cov kauj ruam. Cov txheej txheem cuam tshuam nrog kev sib xyaw vanadium slag nrog sodium carbonate lossis gloiber ntsev), thiab ci ntawm ib qho kub kom hloov lub vanadium rau hauv cov ntsev ua si. Cov xuab zeb roasted yog tom qab ntawd ua kom yaj kom yaj tus vanadate mus rau hauv kev daws, thiab ua kom zoo nkauj thiab ua kom zoo kom tau txais vanadium pentoxide. Qee cov tuam txhab txawv teb chaws ncaj qha Siv Vanadium-Rich Vanadium-cov kabmob titanoz-magnetite los tsim vanadium pentoxide. Ua ntej, cov ore yog tsim rau hauv lub siab xav, uas yog tom qab ntawd tov nrog flux thiab ci hauv lub teb chaws qeeb. Cov xuab zeb ci yog leached nrog dej, cov Vanadium-muaj kev daws teeb meem yog kho nrog ammonium ntsev, thiab thaum kawg ammonium meanadate yog precipitated.
2. Rov qab los ntawm pob zeb thee: cov txheej txheem ntawm kev rho tawm vanadium los ntawm cov txheej txheem ntws-howing-lase-likadium nag lossis daus-ua kom zoo nkauj vanadium. Cov txheej txheem no feem ntau siv nyob rau hauv Suav teb kom rho Vanadium los ntawm pob zeb thee. Nws yog tus cwj pwm los ntawm nws qhov yooj yim thiab ua kom siv tag nrho cov hluav taws xob thermal ntawm pob zeb thee. Qhov tsis zoo yog tias tus nqi rov qab yog qhov tsawg, feem ntau hauv qab 60%. Tebchaws Asmeskas siv cov txheej txheem saum toj no, tab sis siv tshuaj sulfuric kua qaub kua qaub thiab cov kuab tshuaj extraction thiab kev rov qab ua kom txog 70%.
Cov txheej txheem ntau lawm ntawm lub cub rau vanadium pentoxide yog li hauv qab no
Khib catalyst → crushing → hydrochloric acid acid → lim hydrium hydrocium daus → refining → reccination → cov khoom. Cov txheej txheem yooj yim, thiab tus nqi rov qab yog dua 90%. Txoj kev hais kom qeeb ncas yog siv los rho cov vanadium pentoxide. Qhov kev kub-taws kub ntu yog 720-800 degree. Ib qho nyiaj ntawm cov sodium carbonate yog ntxiv rau hauv Vanadium swb kom ua tiav qhov zoo tshaj plaws hloov dua siab tshiab ntawm cov ore. Lub sijhawm nyob ntawm lub ore nyob rau hauv ntu kub-seem ntawm txog 930 qib yuav tsum tau tswj hwm ntawm 5-6 teev. Qhov tsawg kawg nkaus-kub siab ntawm lub Kiln rau ib txwm muaj kev puas tsuaj yuav tsum tsis qis dua 1100 degree, thiab lub zog melting ntawm cov ore yuav tsum tsis pub tshaj 1000 degree.
