Djoko Widajatno, tus thawj coj ntawm lub koom haum Indonesian Mining Association, tau hais tias tsoomfwv txoj kev npaj yuav txwv tsis pub xa tawm bauxite tau txais tos los ntawm ntau lub tuam txhab hauv zos uas tau tsim kev lag luam bauxite smelting.
PT Adaro Zog Tbk tau tsim lub alumina smelter, uas yog ua los ntawm nws cov chaw muag khoom PT Adaro Aluminium Indonesia, thaum lub Kaum Ob Hlis 2021.
Lub tuam txhab kuj tau kos npe rau tsab ntawv xav kom nqis peev US 728 lab los yog sib npaug ntawm 10.41 trillion Rupiah (piv tus nqi ntawm 14,300 rupiah rau US duas) hauv cov nroj tsuag electrolytic aluminium.
Qee cov bauxite smelters tau ua zoo sib xws. Xws li PT Well Harvest Winning AR, PT Indonesia Chemical Alumina, PT Bintan Alumina Indonesia thiab smelters uas yog Inalum thiab PT Antam Tbk.
"Yog tias muaj, tej zaum peb cov khoom siv bauxite tam sim no tau nqus los ntawm cov smelters tshiab thiab cov smelters uas twb tau ua haujlwm lawm. Qhov tseem ceeb, yog tias ua tiav hauv tsev, peb yuav tau txais txiaj ntsig ntxiv los ntawm bauxite rau alumina," Djoko hais rau cov neeg sau xov xwm.
Raws li Ministry of Energy thiab Mineral Resources, Indonesia bauxite reserves suav txog li 4 feem pua, lossis 1.2 billion tons, ntawm tag nrho lub ntiaj teb ntawm 30.3 billion tons. Qhov ntawd yog qhov txaus los ua rau Indonesia ua rau lub ntiaj teb thib rau - cov khoom loj tshaj plaws ntawm bauxite. Lwm lub tebchaws yog Guinea nrog 24 feem pua, Australia nrog 20 feem pua, Nyab Laj nrog 12 feem pua, Brazil nrog 9 feem pua thiab Jamaica nrog 7 feem pua.
Muab hais tias tsis muaj cov smelters tshiab tau ntxiv txij li xyoo 2020, cov khoom siv bauxite hauv tsev tau kwv yees tias yuav ploj mus rau 92 xyoo.
Hauv xyoo 2019, Indonesia tau tsim tawm 19 lab tons ntawm bauxite thiab xa tawm 16.1 lab tons, thaum lub teb chaws bauxite tsim 2.9 lab tons thiab 1.1 lab tons ntawm alumina. Cov khoom no xa tawm thoob ntiaj teb 1.08 lab tons, hauv tsev tsuas yog 46,{11}} tons.
Indonesia tom qab ntawd yuav tsum tau rov ua dua-tso tawm qee qhov 458,000 tonnes ntawm alumina los tsim 250,000 tonnes ntawm electrolytic aluminium.
Kev thov hauv tsev rau txhuas, ntawm qhov tod tes, tshaj 1m tonnes. Qhov ntawd txhais tau hais tias kev lag luam yuav tsum tau rov ua dua -Ntshuam txog 748,000 tonnes ntawm txhuas.
Djoko kwv yees tias kev lag luam tuaj yeem ua rau nws muaj peev xwm nqus tau txhuas ore, tab sis tseem tsis tau muaj kev ntseeg siab tias tsoomfwv cov phiaj xwm tau ua haujlwm "ib nrab-txoj kev siab" thiab tias kev lag luam txhuas tsis tau ua tiav hauv kev nyiam kev nqis peev. . Feem ntau, ob qho tib si sab sauv thiab qis qis, txawm tias cov thee lossis mining, tab tom tos cov tub ua lag luam tshiab.
