Tuam Tshoj Tau Los Ua Qhov Tseem Ceeb Thiab Cuam Tshuam Cov Titanium Hauv Kev Ua Lag Luam Thoob Ntiaj Teb

Txhua txhua xyoo, Tuam Tshoj noj ntau dua 45% ntawm tag nrho cov neeg xav tau thoob ntiaj teb rau cov khoom siv titanium . Tsis tas li ntawd, kev tsim cov titanium daim txhuam cev tau hais los saum toj no tso nyiaj rau ib feem peb ntawm kev tsim khoom hauv ntiaj teb tag nrho, thiab kev tsim tawm ntawm cov pa roj carbon monoxide titanium yog 45% ntawm lub ntiaj teb tag nrho cov khoom. Nws tuaj yeem hais tias Tuam Tshoj tau dhau los ua qhov tseem ceeb tshaj plaws ntawm kev lag luam titanium thoob ntiaj teb. Qhov zoo ntawm Tuam Tshoj tus lag luam titanium thiab kev loj hlob ntawm Tuam Tshoj tus titanium kev lag luam yuav muaj qhov cuam tshuam tseem ceeb ntawm kev lag luam titanium thoob ntiaj teb. Nyob rau hauv xyoo tas los no, qee cov kev cai tshiab thiab kev hloov pauv hauv lub khw tau dhau los ua qhov cuam tshuam rau Tuam Tshoj kev lag luam titanium. Ntsib nrog cov cawv no, Suav cov lag luam tau hloov kho tas li. Nyob rau hauv xyoo tas los no, qhov loj tshaj uas cuam tshuam rau kev ua lag luam yog lub zog coj los ntawm ib puag ncig cov cai. Txij xyoo 2016, Tsoomfwv Suav tau tshaj tawm cov kev kuaj xyuas ib puag ncig thiab nres zam cov tuam txhab uas tsim cov pa phem tawm. Qhov no ua rau txhua lub lag luam yuav tsum nce kev nqis peev ntawm cov cuab yeej tiv thaiv ib puag ncig. Rau qee lub koom haum me thiab nruab nrab, cov peev txheej pib txhim kho cov cuab yeej tiv thaiv ib puag ncig yog dhau qhov lawv muaj peev xwm tiv taus, ua rau qee lub tuam txhab me thiab nruab nrab kom nres ntau lawm thiab tawm ntawm kev ua lag luam. Ntxiv rau, qee qhov kev lag luam muaj kev txwv tsis pub kho cov khoom pov tseg, thiab txhawm rau ua kom muaj kev ua raws li cov pa phem, cov kev lag luam no yuav tsum ua kom tsawg cov khoom pov tseg kom ua tiav cov khoom kho. Txhawm rau txo cov khoom pov tseg, qee lub tuam txhab tseem xaiv rau cov khoom ua tau zoo dua qub, uas ua kom cov nqi ntau lawm.

 

Hauv cov txheej txheem ntawm kev loj hlob sai ntawm titanium kev lag luam hauv Suav teb, qee cov teeb meem tau tshwm sim. Ua ntej tshaj plaws, domestic titanium ore ntau lawm kev loj hlob yog qhov qeeb, uas ua rau kom muaj kev nce zuj zus ntawm kev vam khom rau kev siv ntshuam. Tuam Tshoj tus peev xwm tus peev xwm ntawm titanium tus kheej, uas nce rau 67 feem pua hauv 2014, tau poob mus rau 58 feem pua. Thib ob, thaum qhov kev thov rau cov khoom lag luam titanium ntau ntxiv nce, kev hloov pauv tshwm sim hauv qee qhov chaw ntshuam tseem ceeb, uas ua rau tsis muaj cov khoom lag luam ruaj khov rau qee cov lag luam nqes, uas tau cuam tshuam ntau lawm. Qhov tsis ruaj khov ntawm cov khoom siv raw khoom muaj qhov tsis zoo rau cov khoom lag luam zoo thiab cov nqi tsim khoom ntawm cov khoom lag luam titanium dioxide. Tsis tas li ntawd, qhov kev ua tau zoo ntawm cov khoom lag luam titanium tau tuaj tsawg zuj zus nyob rau xyoo tas los no. Ntawm lawv, qhov kev poob qis ntawm TiO2 cov ntsiab lus ua rau poob qis ntawm kev tsim khoom ntawm cov khoom lag luam titanium dioxide, thiab tseem coj ntau cov khoom pov tseg. Tom qab xyoo 2016, Tuam Tshoj txoj kev tiv thaiv kev tiv thaiv ib puag ncig tau muaj zog ua kom muaj zog, thiab cov khoom pov tseg ntau ntxiv tau ua rau muaj kev cuam tshuam loj heev rau cov chaw tsim khoom lag luam titanium dioxide, thiab qee cov lag luam hauv qee thaj tsam tau txo qis lossis tso tseg kev tsim khoom vim muaj teeb meem emission. Txawm li cas los xij, qhov txo qis ntawm TiO2 cov ntsiab lus feem ntau yog nrog los ntawm kev nce ntawm qhov tsis huv lub ntsiab lus, uas tseem ua rau cov khoom zoo ntawm cov khoom hauv nqes yuav raug cuam tshuam. Kev lag luam hauv qab qis yuav tsum nqis peev ntau dua nyob rau hauv ntau lawm kom tshem tawm qhov cuam tshuam.

 

Raws li Tuam Tshoj txoj kev thov rau cov khoom siv titanium nce sai heev, ntau thiab ntau lub tuam txhab tau nqis peev pab koom nrog kev txawv teb chaws. Tam sim no, Africa yog thaj chaw muaj peev xwm tshaj plaws rau Suav kev lag luam los ua lag luam, thiab Australia kuj tsis yog qhov chaw zoo tshaj plaws rau kev nqis peev. Muaj qee qhov zoo tshaj rau titanium mine tej haujlwm puag ncig Perth uas tab tom tsim. Peb cia siab tias yuav pom ntau cov kev vam meej ntawm kev koom tes thiab yeej-yeej kev koom tes nrog Suav kev lag luam. Nyob rau hauv Suav teb, txawm li cas los xij, vim qhov kev thov loj heev tshwm sim los ntawm kev txhim kho chlorine yav tom ntej, qee qhov kev lag luam tau tsim cov thev naus laus zis tshiab kom muaj ntau cov khoom siv titanium thiav qis kom ua tiav kom tau raws li cov kev xav tau ntawm kev ua haujlwm ntawm chlorinated titanium dioxide, yog li nce tus nqi ntawm low-grade titanium ore. Yog hais tias cov tshuab zoo li kev lag luam tiav, nws yuav daws tau Tuam Tshoj cov khoom lag luam teeb meem. Txog tam sim no, Tuam Tshoj txoj kev thov rau titanium raw cov ntaub ntawv yog yeej los ntawm sulfuric acid titanium ore, tab sis kev txhim kho yav tom ntej yog titanium chloride ore, rutile thiab lwm yam ntaub ntawv raw. Tuam Tshoj cov khoom tsim hluav taws xob hauv titanium tuaj yeem siv tsis tau ua cov khoom siv rau cov tshuaj chlorine, thiab yuav luag txhua tus tso siab rau kev siv ntshuam, uas yog qhov laj thawj vim li cas Tuam Tshoj sim tsim cov thev naus laus zis tshiab los hloov qhov kev siv tau ntawm cov ore titanium. Mus txog thaum cov thev naus laus zis tshiab tshwm sim, Tuam Tshoj txoj kev thov rau yav tom ntej ntawm cov khoom nyoos rau chlorination khi rau thawb tus nqi nce ntxiv.
