Rare earth metalszvakakosha mbishi zvinhu zvekugadzira hydrogen kuchengetedza zvinhu, NdFeB zvechigarire magineti zvinhu, magnetostrictive zvinhu, etc. Izvo zvinoshandiswawo zvakanyanya mumasimbi asina-ferrous uye maindasitiri esimbi.Asi basa rayo resimbi rakasimba kwazvo, uye zvakaoma kuibvisa kubva mumisanganiswa yayo uchishandisa nzira dzakajairwa pasi pemamiriro akajairika.Mukugadzirwa kwemaindasitiri, nzira huru dzinoshandiswa dzakanyungudutswa munyu electrolysis uye kudzikisira kwemafuta kugadzira isingawanzo simbi dzepasi kubva isingawanzo pasi chlorides, fluorides, uye oxides.Yakanyungudutswa munyu electrolysis ndiyo nzira huru yeindasitiri yekugadzira yakasanganiswa isingawanzo simbi yepasi ine yakaderera kunyungudika nzvimbo, pamwe chete.rare earth metalsuyerare earth alloyszvakaita selanthanum, cerium, praseodymium,uyeneodymium.Iyo ine hunhu hwehukuru hwekugadzira chiyero, hapana chikonzero chekudzikisa vamiririri, kuenderera kugadzirwa, uye kuenzanisa hupfumi uye nyore.
Kugadzirwa kwerare earth metalsuye alloys neyakanyungudutswa munyu electrolysis inogona kuitwa mune maviri akanyungudutswa munyu masisitimu, anoti chloride system uye fluoride oxide system.Iyo yekutanga ine yakaderera yekunyungudika, isingadhure mbishi zvinhu, uye nyore kushanda;Iyo yekupedzisira ine yakagadzikana electrolyte kuumbwa, haisi nyore kutora unyoro uye hydrolyze, uye ine yakakwirira electrolysis technical zviratidzo.Yakatsiva zvishoma nezvishoma yekare uye inoshandiswa zvakanyanya mumaindasitiri.Kunyangwe iwo maviri masisitimu aine maitiro akasiyana emaitiro, iyo theoretical mitemo ye electrolysis inowirirana.
Zvekuremarare earth metalsine nzvimbo dzakakwirira dzekunyungudika, iyo yekupisa yekudzikisa distillation nzira inoshandiswa pakugadzira.Iyi nzira ine diki yekugadzira chiyero, kushanda kwepakati, uye mutengo wakakwira, asi inogona kuwana yakakwira-kuchena zvigadzirwa kuburikidza neakawanda distillation.Zvinoenderana nemhando dzekudzikisa maajenti, kune nzira yekudzikisa kupisa kwecalcium, lithium thermal reduction method, lanthanum (cerium) nzira yekuderedza kupisa, nzira yekudzikisa kupisa kwesilicon, carbon thermal reduction method, nezvimwewo.
