Cov kws tshawb fawb hauv University of Stanford ua qhov zoo tshaj plaws hauv kev tsim cov thev naus laus zis tshiab rau kev rho tawm lithium los ntawm cov dej briny. Qhov ntau npaum thiab eco-phooj ywg txoj kev chaw nyobteeb meem lithium concentrationnyob rau hauv tsoos extraction thiab ua. Cov cuab yeej txhawb nqalithium brine concentrationua thiab ua kom nws sai dua, pheej yig dua thiab ib puag ncig ruaj khov ntawm redox-couple electrolysis (RCE). Cov thev naus laus zis tshiab txo tus nqi los ntawm 40% dua li txoj kev rho tawm tseem ceeb.
Rau kev nce ntawm cov tsheb hluav taws xob thiab cov khoom siv hluav taws xob tauj dua tshiab, kev thov thoob ntiaj teb rau lithium tau nce siab nyob rau xyoo tsis ntev los no.Lithium ore concentrationyuav tsum tau mus txog qib tshwj xeeb, ces nws tuaj yeem siv rau hauv lithium roj teeb. Feem ntau cov lithium extraction cia siab rau evaporating brines nyob rau hauv lub pas dej loj nyob rau hauv lub hnub rau ib xyoos los yog ntau tshaj, tawm hauv qab lithium nplua nuj kua.
Tam sim no, lithium ua lub luag haujlwm tseem ceeb hauv lub ntiaj teb lub zog hloov mus rau lub zog ruaj khov. Nws tau kwv yees tias qhov kev thov rau lithium yuav nce los ntawm 0.5 lab metric tons hauv 2021 txog 4 lab metric tons los ntawm 2030. Qhov kev nce ntxiv yog tsav los ntawm kev muaj koob meej thiab kev nthuav dav ntawm cov tsheb hluav taws xob thiab lub zog huv.
Feem ntau, lithium muaj nyob rau hauv brine, seawater thiab crude roj, yog li ntawdLithium concentration ntsuasyog qhov tseem ceeb hauv nws cov extraction, tau txais kev nyeem ntawv meejlithium concentration hauv brine, lithium concentration hauv dej hiav txwv, lithium concentration nyob rau hauv cov roj crude, lithium concentration nyob rau hauv cov roj teb brine.
Ib txwm lithium yog muab rho tawm los ntawm cov pob zeb mined, uas yog ib qho kim dua, lub zog siv zog thiab tsav los ntawm cov tshuaj lom ntau tshaj li brine extraction. Niaj hnub no, lithium extraction hloov mus rau evaporating ntsev-lake brine rau tus nqi qis dua thiab nyiaj txiag ntau dua nrog rau cov nqi ib puag ncig. Cov xwm txheej huab cua yog qhov tseem ceeb cuam tshuam rau kev tsim khoom, cuam tshuam rau kev lag luam lithium muaj peev xwm ua tau raws li qhov xav tau nce.
Nqi & Kev Pabcuam Ib puag ncig
Cov thev naus laus zis tshiab no tau txais txiaj ntsig zoo dua rau qhov laj thawj ntawm cov nqi qis dua ntawm kev tsim thiab tswj cov pas dej loj hnub ci evaporation. Tsis tas li ntawd, kev siv hluav taws xob, dej thiab tshuaj lom neeg muaj txiaj ntsig tsawg dua li ntawm ob txoj hauv kev dhau los. Los ntawm kev zam kev siv av ntau thiab kev siv dej ntawm cov txheej txheem ib txwm muaj, RCE txoj hauv kev kuj tseem txo cov hneev taw ecological ntawm lithium ntau lawm.
Saib tom ntej
Qhov scalability ntawm REC txoj kev tau cog lus ib yam nkaus rau yav tom ntej ntawm cov peev txheej txuas mus ntxiv. Tsis siv neeg thiab ntse lithium extraction yog ib qho irreversible qauv, tshwj xeeb tshaj yog nyob rau hauv tag nrho cov kab ntau lawm integratinginline density meters, qib sensors thiab txawm viscometers. Hu rauLonnmeterrau optimized extraction daws ntawm lithium brine. Koj tuaj yeem tau txais cov lus pom zoo los ntawm peb cov engineers. Tsis txhob yig tau thov daim ntawv tsocai pub dawb tam sim no!
