Tuam Tshoj tus alumina ntau lawm suav txog ib nrab ntawm lub ntiaj teb kev tsim khoom. Raws li Steel Federation, thoob ntiaj teb alumina ntau lawm hauv 2021 yuav yog 118 lab tons. Tuam Tshoj cov alumina ntau lawm yuav yog 64 lab tons, suav txog 48.1% ntawm kev tsim khoom thoob ntiaj teb. Australia cov khoom lag luam alumina nyob qib thib ob, ua raws li Australia thiab Is Nrias teb. , Brazil nyiam tsim ib qho nyiaj ntawm cov khoom siv hauv tsev tshaj li qhov xav tau rau hauv alumina rau kev xa tawm. Txawm hais tias Guinea muaj nplua nuj reserves ntawm high-zoo bauxite, nws yog txwv tsis pub los ntawm nws tsis muaj zog kev lag luam thiab nyhav ncaj qha export bauxite. Txhua xyoo, Tuam Tshoj muaj ib tug loj npaum li cas ntawm alumina, tab sis nws yog tsuas yog muab rau domestic muag khoom. , tsawg exports.
Raws li ALD cov ntaub ntawv, raws li xyoo 2020, lub ntiaj teb alumina tsim muaj peev xwm yog 160 lab tons, kev ua haujlwm muaj peev xwm yog 127 lab tons, thiab kev khiav hauj lwm tus nqi yog 79%; Nyob rau tib lub sijhawm, cov khoom siv hluav taws xob electrolytic aluminium tsim muaj peev xwm yog 75.31 lab tons, kev ua haujlwm muaj peev xwm yog 67.89 lab tons, thiab kev khiav hauj lwm tus nqi yog 90%. Raws li IAI cov ntaub ntawv, lub ntiaj teb metallurgical-qib alumina ntau lawm txij lub Ib Hlis Ntuj txog Lub Xya Hli 2022 yog 11.36 lab tons, ib xyoos ib zaug nce ntawm 3%. Tag nrho cov khoom siv alumina hauv tsev los ntawm Lub Ib Hlis mus txog Lub Yim Hli yog 97.02 lab tons. Thaum lub Yim Hli, lub peev xwm tsim tau yog 8,170 tons, thiab kev khiav hauj lwm tus nqi yog 84%. , ntiaj teb no alumina muaj peev xwm tau nthuav dav.
Tam sim no alumina: electrolytic aluminium smelting ratio yuav tsum yog 1.92: 1, thiab tam sim no alumina: electrolytic aluminium piv yog 2.08: 1. Lub ntiaj teb no alumina ntau lawm mov yog ntau dua li cov electrolytic aluminium ntau lawm thov. Lub peev xwm ntawm alumina siv tau tsis muaj zog dua li cov khoom siv hluav taws xob electrolytic aluminium ntau lawm txij li xyoo 2021. Alumina lub peev xwm tsim tau txuas ntxiv nthuav dav, kev khiav hauj lwm muaj peev xwm hloov me ntsis, thiab alumina ntau lawm muaj peev xwm yog overcapacity.
