Tuam Tshoj tau dhau los ua qhov chaw tsim khoom tseem ceeb thiab kev lag luam rau lub ntiaj teb titanium kev lag luam

Tuam Tshoj txoj kev noj txhua xyoo ntawm titanium raw cov ntaub ntawv suav txog ntau dua 45% ntawm lub ntiaj teb tag nrho cov kev xav tau, ua ke nrog rau yav dhau los hais txog titanium daim txhuam cev ntau lawm suav rau ib feem peb ntawm lub ntiaj teb, kev tsim cov titanium dioxide suav txog 45% ntawm lub ntiaj teb, nws tuaj yeem hais tias Tuam Tshoj tau dhau los ua ib feem tseem ceeb ntawm kev lag luam titanium thoob ntiaj teb tam sim no. Tuam Tshoj txoj kev lag luam titanium yog qhov zoo lossis qhov tsis zoo, kev txhim kho ntawm Tuam Tshoj txoj kev lag luam titanium, yuav muaj kev cuam tshuam tseem ceeb rau kev lag luam titanium thoob ntiaj teb. Nyob rau hauv xyoo tas los no, ntau txoj cai tshiab thiab kev lag luam hloov pauv tau muaj kev cuam tshuam rau Suav kev lag luam titanium. Nyob rau hauv lub ntsej muag ntawm cov kev cuam tshuam no, Suav tuam txhab uas muag tseem pheej hloov kho. Qhov tseem ceeb uas tau muaj kev cuam tshuam loj tshaj plaws ntawm kev ua lag luam nyob rau xyoo tas los no yog kev kub ntxhov los ntawm kev tiv thaiv ib puag ncig. Txij li xyoo 2016, tsoomfwv Suav tau ntxiv dag zog rau nws cov kev txheeb xyuas ib puag ncig thiab tsis zam kev ua txhaum cai ntawm cov tuam txhab ntxiv lawm. Qhov no ua rau nws tsim nyog rau cov tuam txhab lag luam kom nce lawv cov peev txheej hauv cov cuab yeej tiv thaiv ib puag ncig. Rau qee qhov kev lag luam me thiab nruab nrab (SMEs), qhov pib nyiaj txiag rau kev txhim kho cov cuab yeej tiv thaiv ib puag ncig yog dhau qhov lawv muaj peev xwm, ua rau qee cov SMEs kaw kev tsim khoom thiab thim tawm ntawm kev ua lag luam. Tsis tas li ntawd, qee lub tuam txhab muaj peev xwm kho cov khib nyiab tsawg, yog li txhawm rau kom ntseeg tau tias lawv muaj peev xwm ua tau raws li cov emissions, lawv yuav tsum tau txo lawv cov khoom kom phim lawv cov peev txheej kho cov khib nyiab. Txhawm rau txo qis kev tsim khoom pov tseg, qee lub tuam txhab kuj xaiv cov khoom siv zoo dua, tab sis qhov no kuj thawb lawv cov nqi tsim khoom.

Txoj kev loj hlob sai ntawm Tuam Tshoj txoj kev lag luam titanium kuj tau nthuav tawm ntau yam teeb meem. Ua ntej, domestic titanium ore ntau lawm tau loj hlob kuj maj mam, ua rau ib tug maj mam nce nyob rau hauv dependence rau imported ore. Tuam Tshoj tus titanium ore tus kheej txaus tus nqi nce mus txog 67% hauv 2014, tab sis tam sim no tau poob rov qab mus rau 58%. Qhov thib ob, thaum qhov kev thov rau cov khoom siv titanium tuaj yeem loj hlob, muaj kev hloov pauv hauv qee lub tebchaws loj tuaj, ua rau qee lub lag luam qis qis tsis muaj cov khoom siv raw khoom ruaj khov, uas tau ua rau muaj kev cuam tshuam rau kev tsim khoom. Cov khoom tsis ruaj khov ntawm cov khoom siv raw ntawm cov khoom zoo thiab cov nqi tsim khoom ntawm cov tuam txhab titanium dioxide muaj kev cuam tshuam tsis zoo. Tsis tas li ntawd, qhov zoo ntawm titanium ore imported tau poob qis hauv xyoo tas los no. Ntawm lwm yam, qhov poob ntawm TiO2 cov ntsiab lus tau ua rau txo qis hauv kev tsim khoom ntawm cov tuam txhab titanium dioxide, nrog rau kev tsim cov khoom pov tseg ntau dua. Tom qab xyoo 2016, Tuam Tshoj txoj kev tiv thaiv ib puag ncig tau muaj zog ntxiv, thaum qhov kev nce hauv cov pov tseg tau ua rau muaj kev kub ntxhov rau cov tuam txhab titanium dioxide, nrog qee qhov ntawm lawv txo qis kev tsim khoom lossis kaw ib ntus vim muaj teeb meem emission. Qhov txo qis hauv TiO2 cov ntsiab lus feem ntau yog nrog kev nce hauv cov ntsiab lus ntawm cov ntsiab lus tsis huv, thiab qhov no tau ua rau cov khoom lag luam qis qis raug cuam tshuam. Cov lag luam hauv qab yuav tsum tau nqis peev ntau dua cov nqi hauv kev tsim khoom kom tshem tawm qhov cuam tshuam.

Nrog rau kev nce ceev hauv Tuam Tshoj txoj kev thov rau titanium raw khoom, ntau thiab ntau lub tuam txhab tau pib nqis peev hauv mines txawv teb chaws. Tam sim no, Africa yog thaj chaw tseem ceeb tshaj plaws rau Suav lag luam los nqis peev, thiab Australia kuj yog qhov chaw tsis zoo rau kev nqis peev, nrog qee qhov zoo tshaj plaws titanium mining tej yaam num nyob rau hauv kev loj hlob nyob ib ncig ntawm Pas. Peb kuj cia siab tias yuav pom muaj kev vam meej ntxiv ntawm kev koom tes nrog cov tuam txhab suav thiab paub txog qhov xwm txheej yeej-yeej. Hauv Suav teb, vim qhov kev thov loj heev los ntawm cov phiaj xwm chlorination yav tom ntej, qee lub tuam txhab tab tom tsim cov thev naus laus zis tshiab los ua kom tus nqi qis ntawm titanium ore los ntawm kev ua kom tau raws li cov kev cai ntawm chlorination. Yog hais tias xws li tshuab tau ua tiav industrialized, nws yuav daws tau cov khoom siv raw cov teeb meem ntsib los ntawm Tuam Tshoj. Txog tam sim no, Tuam Tshoj qhov kev thov rau titanium raw cov ntaub ntawv yog tus thawj ntawm sulfuric acid titanium ore, tab sis lub neej yav tom ntej kev loj hlob taw tes ua chloride titanium ore, rutile thiab lwm yam ntaub ntawv raw. Tuam Tshoj lub teb chaws tsim titanium ore Cheebtsam tsis tuaj yeem siv los ua cov khoom siv raw rau cov txheej txheem chlorination, thiab yuav luag txhua tus ntawm lawv tso siab rau kev xa khoom, uas yog qhov laj thawj tseem ceeb rau Tuam Tshoj txoj kev siv zog los tsim cov thev naus laus zis tshiab los hloov cov kev siv ntawm titanium ore. Txog thaum lub tshuab tshiab tshwm sim, Tuam Tshoj qhov kev thov loj rau chlorinated feedstocks yav tom ntej yog khi kom thawb lawv cov nqi ntxiv.
