Kukhona izindlela ezimbili ezijwayelekile zokwenza i-rare earth metallurgy, okuyi-hydrometallurgy kanye ne-pyrometallurgy.
I-Hydrometallurgy ingeyendlela ye-chemical metallurgy, futhi yonke le nqubo iyingxenye yesixazululo ne-solvent.Isibonelo, ukubola komhlaba ongavamile ukugxila, ukuhlukaniswa nokukhishwa kweama-oxide omhlaba angavamile, izinhlanganisela, nezinsimbi ezingavamile zomhlaba ezingabodwa zisebenzisa izinqubo zokuhlukaniswa kwamakhemikhali ezifana nemvula, icrystallization, ukunciphisa i-oxidation, ukukhishwa kwe-solvent, kanye nokushintshisana kwe-ion.Indlela evame ukusetshenziswa kakhulu i-organic solvent extraction, okuyinqubo yendawo yonke yokuhlukaniswa kwemboni yezinto ezihlanzekile ezingavamile zomhlaba owodwa.Inqubo ye-hydrometallurgical iyinkimbinkimbi, futhi ukuhlanzeka komkhiqizo kuphezulu.Le ndlela inezinhlobonhlobo zezicelo ekukhiqizeni imikhiqizo eqediwe.
Inqubo ye-pyrometallurgical ilula futhi inokukhiqiza okuphezulu.Umhlaba ongavamileI-pyrometallurgy ikakhulukazi ihlanganisa ukulungiswa kwama-alloys omhlaba angavamile ngokunciphisa i-silicothermic, izinsimbi zomhlaba ezingavamile noma ama-alloys nge-electrolysis kasawoti encibilikisiwe, kanye nama-alloys omhlaba angavamile ngokunciphisa ukufudumala kwensimbi.Isici esivamile se-pyrometallurgy ukukhiqizwa ngaphansi kwezimo zokushisa eziphezulu.
