Aluminium ntau muaj tsib theem.
Thawj, Bauxite Mining: Australia, Guinea, thiab Tuam Tshoj ua kav lub ntiaj teb bauxite lub ntiaj teb extraction, feem ntau los ntawm kev qhib-qhov kev pheej hmoo ntawm kev pheej hmoo.
Ib xi nkoos, BAYER Txheej Txheem: Bauxite yog ua kom zoo rau hauv Alumina (al₂o₃) Siv Caustic Dej qab zib, tsim cov av nkos "liab".
Thib peb, elololsissis(Hall-hérice cov txheej txheem): Alumina yog yaj hauv Molten Cryolite (950 degree), thiab hluav taws xob sib cais nws mus rau hauv txhuas hlau thiab co₂, siv 13-15 ib tuj.
Thib plaub, sib ntxaws: Cov ntsiab lus li tooj liab (rau lub zog) lossis magnesium (rau corrosion tsis kam) yog ntxiv rau cov khoom ua kom titoror.
Tsib, ubno: Seem txhuas yog remelted siv 95% tsawg zog dua li kev tsim khoom, kaw lub voj sustainability. Kev nrhav hluav taws xob zoo li inert anodes tsom rau tshem tawm co₂ emissions, thaum lub sij hawm liab av yog rov ua dua nyob rau hauv xis mas ntau lawm. Txawm li cas los xij, kev cia siab rau cov hluav taws xob tua hluav taws smelters hauv Suav teb tseem muaj kev txhawj xeeb ib puag ncig.
