Raws li lub caij qhuav los txog, nag lossis daus hauv Yunnan yuav txo qis thiab qhov teeb meem ntawm kev siv dej tsis txaus yuav tshwm sim dua. Qhov no yuav ua rau cov lag luam electrolytic aluminium hauv Yunnan ntsib kev txiav ntau lawm dua. Raws li kev lag luam rumors, electrolytic aluminium lag luam hauv Yunnan tuaj yeem pib siv cov phiaj xwm txo qis txij thaum pib lub Kaum Ib Hlis, thiab yuav txo qis kev tsim khoom los ntawm 20% raws li lub peev xwm ua haujlwm tam sim no. Qhov kev txiav tawm no yuav kav mus txog rau thaum xaus ntawm lub xyoo.
Qhov no yuav tsum muaj kev cuam tshuam txog li 1.1 lab tonnes ntawm electrolytic aluminium muaj peev xwm, uas yuav txo qhov kev thov txhua xyoo rau alumina los ntawm kwv yees li 2 lab tonnes raws li ib chav noj ntawm 1.93 tonnes ntawm alumina ib tonne ntawm txhuas. Qhov no yuav muaj qee yam tsis zoo rau kev lag luam alumina.
Kev siv hluav taws xob tsis txaus vim lub caij qhuav tuaj yeem yog qhov tseem ceeb rau kev txo cov khoom siv no. Raws li ib cheeb tsam nplua nuj nyob rau hauv hydropower peev nyob rau hauv Tuam Tshoj, Yunnan yog heev nyob rau hauv hydropower rau nws lub hwj chim mov. Thaum lub caij qhuav, cov khoom siv hluav taws xob hauv dej yuav nyob rau hauv siab, ua rau muaj hluav taws xob tsis txaus, uas yuav cuam tshuam rau cov khoom lag luam ntawm electrolytic aluminium.
Lub cheeb tsam Yunnan yog ib qho tseem ceeb ntawm electrolytic aluminium ntau lawm hauv Suav teb, thiab kev lag luam electrolytic aluminium yog cov neeg siv khoom loj ntawm alumina. Yog li ntawd, kev txo qis ntawm electrolytic aluminium cov lag luam hauv Yunnan yuav cuam tshuam ncaj qha rau kev thov thiab cov khoom siv ntawm alumina. Hauv kev lag luam alumina, kev hloov pauv hauv kev thov thiab cov khoom siv yuav cuam tshuam ncaj qha rau tus nqi thiab kev lag luam sib txawv.
Kev ua raws li txoj kev npaj txo kev tsim khoom kuj tseem yuav muaj qee yam cuam tshuam rau cov saw hlau muaj feem xyuam. Alumina yog ib qho tseem ceeb raw cov ntaub ntawv rau kev lag luam kev lag luam, thiab nws cov kev txiav txiav yuav ncaj qha cuam tshuam rau kev tsim khoom thiab kev loj hlob ntawm kev lag luam downstream xws li txhuas cov khoom, tsheb thiab kev tsim kho. Tsis tas li ntawd, kev txiav ntau lawm kuj yuav muaj kev cuam tshuam rau kev lag luam alumina, uas yuav ua rau muaj kev xa khoom ntau ntawm alumina, yog li ua rau muaj kev kub ntxhov ntawm alumina nqi.
