Kev Tshawb Fawb Kev Ua Lag Luam Ntawm High Purity Alumina
Aug 02, 2022
Los ntawm kev siv uas twb muaj lawm, alumina tuaj yeem faib ua ob pawg: ib qho yog metallurgical alumina siv rau electrolytic aluminium ntau lawm, accounting rau feem ntau ntawm alumina ntau lawm; lwm yam yog non-metallurgical alumina, nrog rau cov uas tsis yog-metallurgical alumina Cov aluminium hydroxide thiab alumina siv, los yog ntau yam alumina, yog txawv heev ntawm metallurgical alumina vim lawv txawv zog, feem ntau nyob rau hauv cov nqe lus ntawm purity, tshuaj muaj pes tsawg leeg, morphology. , thiab puab.
Alumina yog cov khoom siv tseem ceeb rau kev ua txhuas, yog li cov refiners feem ntau muag nws rau txhuas smelters. Aluminium yog siv rau hauv txhua yam ntawm tsheb mus rau cookware. kuv lub teb chaws yog lub ntiaj teb loj tshaj plaws txhuas cov neeg siv khoom thiab tsim khoom. Kev poob qis ntawm alumina tus nqi yuav zoo li txhawb Tuam Tshoj txoj kev tsim khoom txhuas thiab dampen ntshuam thov. Alumina feem ntau suav rau 40 feem pua ntawm thawj cov nqi tsim khoom txhuas.
Thaum kawg ntawm 2015, lub teb chaws alumina muaj peev xwm yog 70 lab tons / xyoo, kev khiav hauj lwm muaj peev xwm yog 61.04 lab tons / xyoo, thiab kev khiav hauj lwm tus nqi yog 87.2 feem pua. Kev khiav hauj lwm tus nqi ntawm alumina lag luam ib txwm tau khaws cia nyob rau theem siab. Hauv xyoo 2015, kev lag luam loj ntawm kuv lub teb chaws alumina kev lag luam mus txog 126.481 billion yuan, ib xyoos ib zaug nce ntawm 10.3 feem pua, thiab cov zis tau mus txog 49.6524 lab tons, ib xyoos ib zaug nce ntawm 10.1 feem pua.
Nyob rau hauv xyoo tas los no, kuv lub teb chaws txoj kev lag luam alumina tau tsim sai heev thiab tau dhau los ua cov neeg tsim khoom thiab cov neeg siv khoom loj tshaj plaws hauv ntiaj teb, ua rau muaj qhov xwm txheej ntawm cov khoom siv bauxite nruj, overcapacity, thiab kev poob loj hauv kev lag luam hauv ntau thaj tsam.
Tam sim no, kuv lub teb chaws cov khoom lag luam alumina muaj qib siab ntawm homogeneity thiab yog cov khoom lag luam hauv kev lag luam. Kev sib tw ntawm cov lag luam feem ntau yog kev sib tw ntawm cov nqi. Tam sim no, tus naj npawb ntawm cov lag luam hauv kuv lub teb chaws txoj kev lag luam alumina tau poob qis. Nyob rau hauv 2015, muaj txog 500 alumina lag luam nyob rau hauv Tuam Tshoj, nrog ib tug nruab nrab muaj peev xwm ntawm txog 200, 000 tons ib xyoo. Feem ntau ntawm lawv yog cov lag luam me thiab nruab nrab, thiab kev lag luam concentration tsawg. Muaj qhov chaw loj rau kev koom ua ke yav tom ntej. Cov lag luam nkag mus rau hauv kev lag luam alumina hauv tsev nrog qhov zoo ntawm cov peev txheej tsawg, cov nqi khiav lag luam tsawg, thiab cov cuab yeej siv siab, thiab qee lub tuam txhab tsim hluav taws xob txuas ntxiv cov saw hlau kom nkag mus rau kev lag luam alumina, uas yuav ua rau muaj kev sib tw hnyav ntawm cov lag luam alumina hauv tsev. yav tom ntej.
1. Kev tsim khoom alumina hauv tsev
Hauv tsib lub xyoos dhau los, Tuam Tshoj lub peev xwm alumina ntau lawm tau nyob rau theem nthuav dav. Raws li cov ntaub ntawv los ntawm National Bureau of Statistics: nyob rau hauv 2011, kuv lub teb chaws alumina tso zis mus txog 34.172 lab tons; Nyob rau hauv 2014, kuv lub teb chaws alumina tso zis mus txog 52.3991 lab tons; xyoo 2015, kuv lub teb chaws alumina mus txog 58.979 lab tons. kuv lub teb chaws xav kom tsim tau 80 lab tons ntawm alumina hauv 2018.
