Kev Tshawb Fawb Txog Kev Siv Khoom thiab Kev Xav Tau Rau Alumina

Los ntawm lub ntiaj teb no muaj peev xwm ntau lawm foundations, alumina ntau lawm muaj peev xwm yog mas faib nyob rau hauv lub teb chaws xws li Tuam Tshoj, Australia, Brazil, Is Nrias teb, Russia, Saudi Arabia, thiab Jamaica. Nyob rau hauv 2011-2021, lub ntiaj teb no alumina muaj peev xwm tsim tau nce los ntawm 101.53 lab tons / xyoo rau 168.89 lab tons / xyoo, nce 67.37 lab tons / xyoo, nrog rau qhov nruab nrab txhua xyoo kev loj hlob ntawm 5.2%, tuav txoj kev loj hlob tsis tu ncua . Nyob rau tib lub sijhawm, Tuam Tshoj lub peev xwm tsim khoom alumina tau nce los ntawm 47.38 lab tons hauv ib xyoos rau 90.38 lab tons hauv ib xyoos, nce ntawm 43 lab tons hauv ib xyoos, nrog qhov nruab nrab txhua xyoo kev loj hlob ntawm 6.7%. Nws tuaj yeem pom tau tias Tuam Tshoj yog lub luag haujlwm tseem ceeb rau kev loj hlob ntawm lub ntiaj teb alumina muaj peev xwm. Raws li qhov kawg ntawm 2021, kev sib koom ua ke muaj peev xwm ntawm Tuam Tshoj (54%), Australia (16%), Brazil (7%), thiab Is Nrias teb (5%) suav txog ntau dua 80% ntawm lub ntiaj teb tag nrho cov peev txheej tsim khoom. Ntawm lawv, kev vam khom rau kev lag luam muaj zog, Tuam Tshoj tau ua lub ntiaj teb cov neeg tsim khoom loj tshaj plaws thiab cov neeg tsim khoom ntawm alumina rau 15 xyoo sib law liag. Australia, Brazil, thiab Jamaica tau dhau los ua lub ntiaj teb cov neeg tsim khoom loj ntawm alumina vim lawv cov peev txheej bauxite ntau, cov nqi hluav taws xob tsawg, thiab cov chaw thauj mus los tau zoo.
Kev faib tawm ntawm cov khoom siv alumina hauv tsev muaj peev xwm muaj peev xwm ua tau zoo, feem ntau yog tsom rau hauv cov cheeb tsam uas muaj cov peev txheej bauxite thiab cov chaw nres nkoj ntug dej hiav txwv, feem ntau hauv Shandong, Shanxi, Guangxi, Henan, thiab Guizhou. Raws li qhov kawg ntawm 2021, Tuam Tshoj lub peev xwm alumina yog 90.35 lab tons hauv ib xyoos, suav txog 53.9% ntawm lub ntiaj teb tag nrho cov peev txheej. Lub peev xwm ntau lawm tau nce 1.7 lab tons hauv ib xyoos piv rau qhov kawg ntawm lub xyoo dhau los, nrog rau kev loj hlob ntawm 1.5%. Lub peev xwm tshiab tau ntxiv yog qhov tseem ceeb hauv cheeb tsam Guangxi thiab Guizhou. Los ntawm kev xa tawm, kev tsim muaj peev xwm faib qauv ntawm Tuam Tshoj txoj kev lag luam alumina yog qhov ruaj khov, nrog Shandong lub peev xwm alumina ntau lawm (30 lab tons / xyoo) qeb duas, suav txog ze li ib feem peb ntawm lub teb chaws tag nrho cov peev txheej; Shanxi (23.8 lab tons / xyoo), Henan (12.6 lab tons / xyoo), thiab Guangxi (12 lab tons / xyoo) kuj muaj cov feem ntau, thiab cov alumina muaj peev xwm ntawm plaub lub xeev thiab cheeb tsam muaj ze li ntawm 87% ntawm tag nrho alumina ntau lawm muaj peev xwm nyob rau hauv lub teb chaws. Thaum kawg ntawm 2021, Tuam Tshoj txoj kev npaj alumina muaj peev xwm yog kwv yees li 16.2 lab tons hauv ib xyoos, qhia tias muaj peev xwm alumina tseem nyob rau theem nthuav dav. Los ntawm txoj kev loj hlob ntawm alumina, nws tuaj yeem pom tias lub peev xwm tsim khoom ntawm Tuam Tshoj txoj kev lag luam alumina tsis tshua muaj kev tshem tawm, thiab muaj qee lub sijhawm kaw thiab tsis muaj peev xwm ntau lawm, tos rau lub lag luam rov pib tsim khoom ntawm lub sijhawm tsim nyog, thiab yuav tsis tawm tag nrho. cov txheej txheem ntau lawm. Nyob rau hauv 2014, 1.2 lab tons / xyoo alumina muaj peev xwm ntawm Chinalco Guizhou ceg raug kaw, tab sis nyob rau hauv 2015, Guizhou Huajin Aluminium Industry Company resumed ntau lawm nrog ib tug muaj peev xwm ntawm 1.6 lab tons / xyoo; Xyoo 2022, thawj tus tswv ntawm alumina cog hauv Suav teb, Nanchuan Pioneer Alumina Cog, nrog lub peev xwm ntau lawm ntawm 800000 tons hauv ib xyoos, raug kaw. Nyob rau tib lub sijhawm, Bosai Jiulong Wanbo Alumina Project nrog lub peev xwm ntau lawm ntawm 3.6 lab tons hauv ib xyoos tau muab tso rau hauv kev ua haujlwm, ob qho tib si yog kev hloov pauv ntawm cov khoom qub thiab tshiab muaj peev xwm nyob rau hauv lub system. Raws li lub peev xwm tsim tawm tshiab ntawm alumina tseem nce ntxiv, lub sijhawm tos rau kev tsim khoom rov pib dua kuj tseem yuav ntev. Yog tias tus nqi qauv tsis tuaj yeem txhim kho thiab ua kom zoo dua qub, qhov ntsuas ntawm qhov kev txo qis yuav nce ntxiv, thiab kev hloov pauv ntawm cov khoom qub thiab tshiab yuav dhau los ua lub ntsiab lus tseem ceeb ntawm Tuam Tshoj txoj kev lag luam alumina hauv ob peb xyoos tom ntej no.
