Ingabe izinsimbi zomhlaba ezivamile noma amaminerali?

Umhlaba ongavamileyinsimbi. I-Rare Earth iyigama elihlangene lezinto eziyi-17 zensimbi etafuleni lesikhathi, kufaka phakathi izinto zaseLanthanide neScandium ne-YTTRIUM. Kunezinhlobo ezingama-250 zamaminerali omhlaba avamile emvelweni. Umuntu wokuqala owathola umhlaba ongavamile kwakungu-Gadolin waseFinland. Ngo-1794, wahlukanisa uhlobo lokuqala lwento yomhlaba engandile kusuka ku-ore esindayo efana ne-asphalt.

I-Rare Earth iyigama elihlangene lezinto eziyi-17 zensimbi etafuleni lezikhathi zamakhemikhali. Zingukukhanya komhlaba okukhanyayo,I-lanthanum, i-cerium, i-prayeodymium, neodymium, i-Promethimium, iSamarium, ne-Europium; Izinto ezisindayo zomhlaba ezingavamile: I-Gadolium, i-Terbium, i-Dysprosium, iHolmium, i-Erbium, i-Thulium, i-ytterbium, i-lutetium, i-scandium ne-yttrium.Imihlaba engavamile ikhona njengamaminerali, ngakho-ke angamaminerali kunokuba inhlabathi. I-China inendawo ecebile kunazo zonke emhlabeni, ikakhulukazi ezigxile ezifundazweni nasemadolobheni afana ne-Internet Mongolia, uShandong, uSichuan, Jiangxi, njll.

Umhlaba ongandile eMhlabeni Ogxile Emhlabeni ngokuvamile ngokuvamile ekhefini le-carbonate, ama-fluorides, ama-phosphates, oxicades, noma ama-milicates. Izinto zomhlaba ezingandile kumele ziguqulwe zibe ngamakhompiyutha ancibilike emanzini noma ama-inorganic acid ngokusebenzisa izinguquko ezahlukahlukene zamakhemikhali, bese kuthi izinqubo ezinjengokuchithwa, noma ukudilizwa ukukhiqiza imikhiqizo ehlukahlukene ye-chlorides yomhlaba, ongasetshenziswa njengemikhiqizo noma izinto ezingavuthiwe zokuhlukanisa izinto zomhlaba ezingandile. Le nqubo ibizwa ngokuthi yiRare Earth Gxila ukubola, eyaziwa nangokuthi ukwelashwa kwangaphambili.
