Luamtxiag Kev Tshaj Tawm rau lub tshuab ua haujlwm sib cav siv neodymium hauv nws cov qauv 3 Lub Nroog Khwv Tsheb rov mus ntxiv ntawm cov khoom siv hlau uas tsis tshua muaj hlau nplaum hlau uas tau muaj rau xyoo tau vim yog kev tshem tawm ntawm kev tsim tawm ntawm sab saum toj.
Cov kev siv dag zog los ntawm tsoom fwv thoob ntiaj teb kom hla cov pa roj carbon monoxide uas ua los ntawm cov pob txha muaj roj hlawv tsav tsheb yog kev tsav tsheb rau cov tsheb fais fab thiab cov hlau siv los ua rau lawv, xws li lithium thiab cobalt uas yog cov khoom tseem ceeb rau cov roj teeb.
Tam sim no tus tsom teeb rau ntawm neodymium. Muaj ntau lub tsheb pib tau siv cov tshuab hluav taws xob txuas mus los ntawm cov hlau uas cia siab rau cov hlau vim lawv feem ntau sib zog, muaj zog dua thiab ntau dua li cov khoom siv hluav taws xob uas yog raws li tooj liab.
Tab sis nws yog qhov hloov mus rau neodymium los ntawm Tesla, ib qho kev pib txiag uas tau staked nws yav tom ntej nyob rau hauv lub tsheb fais fab, uas yog qhia txog txoj kev kev lag luam yog tsiv thiab cov kev taw qhia ntawm kev thov rau lub ntiaj teb tsis tshua muaj hlau.
Kev tshawb nrhiav pab pawg kwv yees hais txog kev lag luam rau neodymium-iron-boron hlau uas siv rau cov motors tam sim no muaj nqis tshaj $ 11.3 billion, nrog rau cov hlau nplaum nce rau ntawm cov paj xyoob txhua xyoo ntawm 8.5 feem pua ntawm xyoo 2010 thiab 2017. (Rau ib daim duab ntawm Neodymium kev ua lag luam tshuav nyem reut.rs/2FD6bUb)
"Qee lub cav tsheb hluav taws xob siv cov txuj ci tseem ceeb hauv kev lag luam, tej zaum cov neeg nto moo tshaj plaws yog Tesla Model 3 Long Range. Tag nrho lwm yam Tesla qauv - Model X thiab Model 3 tus qauv - siv induction motors, "said David Merriman, ib tug laus kws tshawb fawb ntawm metals consultancy Roskill.
Ntiaj teb xav ntawm 31,700 tonnes rau neodymium xyoo tas los twb outstripped mov los ntawm 3,300 tonnes, nws said. Kev xav tau xav tias yuav nce mus 34,200 tonnes rau xyoo no thiab 38,800 tonnes hauv xyoo 2019, tawm qhov ntau dua.
"Tesla qhov kev txiav txim siab hloov mus rau cov hlau nplaum tas li tau pauv qhov kev lag luam ntawm kev ua lag luam," said ib tug thawj coj ntawm cov thawj coj nyiaj txiag uas tshwj xeeb hauv cov hlau.
Tus nqi ntawm neodymium tam sim no txog $ 70 ib lub hli, poob qab ntawm $ 500 ntaus tom qab Tuam Tshoj tuav rov qab xa mus rau Nyij Pooj xyoo 2010 nyob rau hauv ib kab dhau hiav txwv Islands tuaj tab sis nws tseem 40 feem pua siab tshaj thaum pib ntawm 2017.
Tuam Tshoj, uas rov tsim dua tshiab neodymium hauv xyoo 2015, tau cog cov khoom cog qoob loo thoob cov teb chaws tsis tshua muaj hlau hauv xyoo 2010, hais tias nws xav kom muaj kev lim hiam thiab khaws cia cov kev pab.
