Kev Ntsuam Xyuas Daim Ntawv Qhia Txog Kev Txhim Kho Kev Txhim Kho thiab Kev Muag Khoom ntawm Titanium Kev Lag Luam los ntawm 2024 txog 2030
Titanium yog ib qho ntawm cov khoom siv dav tshaj plaws thiab ntau tshaj plaws nyob rau hauv lub ntiaj teb lub pob zeb, suav txog 0.61% ntawm nws qhov hnyav thiab qeb thib 9. Txawm li cas los xij, nyob rau hauv qhov xwm txheej, nws yog dispersed thiab nyuaj rau extract, thiab suav hais tias yog ib tug tsis tshua muaj hlau.
titanium muaj cov tshuaj lom neeg muaj zog thiab tsis muaj nyob hauv cov titanium hauv cov xwm txheej. Nws yog ib qho yooj yim los ua ke nrog oxygen. Titanium nyob rau hauv cov zaub mov feem ntau muaj nyob rau hauv daim ntawv ntawm TiO2 thiab titanates, feem ntau coexisting nrog hlau los tsim ntau yam minerals. Muaj ntau tshaj 140 minerals nrog TiO2 cov ntsiab lus ntau tshaj 1% ib leeg, ntawm uas tsuas yog ntau tshaj 10 muaj nuj nqis, feem ntau suav nrog rutile, ilmenite, ilmenite, rutile, perovskite, thiab lwm yam.
Txawm li cas los xij, vim muaj kev vam khom siab ntawm tus nqi kev lag luam thiab cov peev txheej mining ntawm titanium cov peev txheej ntawm cov khoom siv zoo, cov khoom siv titanium ore tam sim no nrog kev lag luam mining nqi yog ilmenite thiab rutile. Ntawm lawv:
(1) Titanium hlau ore: Titanium hlau ore muab faib ua pob zeb ore thiab xuab zeb ore. TiO2 qib ntawm titanium mloog zoo xaiv los ntawm pob zeb ore feem ntau yog 42% -48%, thaum TiO2 qib ntawm titanium concentrate xaiv los ntawm cov xuab zeb ore tuaj yeem tshaj 50%. titanium hlau ore tam sim no yog qhov tseem ceeb tshaj plaws titanium ore peev txheej, uas tuaj yeem siv ncaj qha los ua cov khoom siv raw los ua titanium dioxide lossis daim txhuam cev titanium. Txawm li cas los xij, cov txheej txheem no yuav ua rau muaj kev kub ntxhov ib puag ncig thiab pov tseg ntau ntawm cov peev txheej hlau. Txhawm rau kom siv tag nrho cov hlau hauv ilmenite, ntau cov smelters siv ilmenite ua raw khoom rau hluav taws xob rauv smelting, tau txais npua hlau thiab siab titanium slag, uas yog siv los ua raw cov ntaub ntawv los ua daim txhuam cev titanium, titanium tetrachloride lossis titanium dioxide.
(2) Rutile: Rutile yog ib qho ntawm cov xuab zeb loj tshaj plaws hauv titanium ore, nrog qib siab thiab siab TiO2 cov ntsiab lus. Nws kuj muaj cov impurity hais xws li Fe, Mg, Al, Si, Ca, thiab lwm yam. Tom qab tau txais txiaj ntsig los ntawm txoj kev xws li kev sib cais sib nqus, sib nqus sib nqus, thiab electrostatic sib cais, qib siab concentration nrog cov ntsiab lus siab TiO2 tuaj yeem tau txais, uas tuaj yeem ua tau. siv los tsim daim txhuam cev titanium, titanium tetrachloride, titanium dioxide thiab lwm yam khoom. Txawm hais tias ntuj hematite muaj qhov ua tau zoo, nws cov peev txheej me me, ua rau nws nyuaj rau kev ua kom tau raws li qhov xav tau ntau lawm. Yog li ntawd, ib tug loj npaum li cas ntawm hluavtaws hematite (tseem hu ua hluavtaws hematite) yuav tsum tau tsim los ua ib tug hloov.
Tam sim no, cov tuam txhab lag luam tseem ceeb feem ntau siv ilmenite ua cov khoom siv raw thiab siv txoj hauv kev xws li sulfuric acid leaching, hydrochloric acid leaching, xaiv chlorination, thiab txo xeb kom cais cov hlau feem ntau hauv cov hlau ore, ua cov khoom siv titanium nplua nuj nrog tib yam. muaj pes tsawg leeg thiab cov khoom siv raws li ntuj hematite. Nws yog qhov zoo tshaj plaws hloov rau ntuj hematite.
Lub ntiaj teb no titanium ore peev txheej yog ilmenite, concentrated nyob rau hauv lub teb chaws xws li Tuam Tshoj, Australia, thiab Is Nrias teb. Raws li cov ntaub ntawv los ntawm Teb Chaws Asmeskas Geological Survey, tag nrho lub ntiaj teb reserves ntawm titanium ore kev pab nyob rau hauv 2022 yog kwv yees li 700 lab tons (xws li TiO2), uas cov reserves ntawm ilmenite thiab rutile peev yog 650 lab tons thiab 49 lab tons feem, suav txog 92.86% thiab 7.00%, feem.
Los ntawm lub regional foundations, raws li cov ntaub ntawv los ntawm Teb Chaws Asmeskas Geological Survey, ilmenite cov kev pab cuam feem ntau yog muab faib nyob rau hauv Tuam Tshoj thiab Australia, mus txog 190 lab tons (TiO2 cov ntsiab lus, tib yam hauv qab no) thiab 160 lab tons raws li nyob rau hauv 2022, accounting rau 27% thiab 23%, feem. Rutile cov peev txheej feem ntau yog muab faib rau hauv Australia, suav txog 63%, kwv yees li 30 lab tons. Tuam Tshoj muaj cov nplua nuj titanium ore kev pab, nrog rau tag nrho cov cia ntawm 230 lab tons, suav txog 30.7%.
Txawm hais tias Tuam Tshoj muaj cov peev txheej loj thiab nthuav dav ntawm cov khoom siv titanium, feem ntau ntawm lawv yog cov qib qis qis qis nrog rau ntau hom minerals. Ntau tshaj 90% ntawm cov hlau ore yog pob zeb hom vanadium titanium magnetite, nrog cov hlab ntsha siab thiab cov qauv ntom ntom, ua rau cov ntxhia sib cais nyuaj. Ua ke nrog cov cuab yeej siv hauv tsev tsis paub qab hau, kev siv dav siv tsawg, uas tsis tuaj yeem ua tau raws li qhov xav tau hauv tsev rau titanium ore.
Yog li ntawd, Tuam Tshoj muaj qee yam kev thov rau cov qib siab thiab cov khoom zoo titanium, nrog rau sab nraud dependence ntawm li 40%. Raws li Titanium Zirconium Hafnium ceg ntawm Tuam Tshoj Nonferrous Hlau Industry Association, nyob rau hauv 2022, muaj kwv yees li 3.144 lab tons ntawm domestically tsim titanium ore (TiO2 ntsiab lus, tib yam hauv qab no) thiab 1.553 lab tons ntawm imported titanium ore.
