Indlela yokunciphisa ukushisa kwe-calcium fluoride esetshenziselwa ukukhiqizwa kweesindayoizinsimbi zomhlaba ezingavamilengokuvamile kudinga amazinga okushisa angaphezu kuka-1450 ℃, okuletha ubunzima obukhulu ukucubungula amathuluzi nokusebenza, ikakhulukazi emazingeni okushisa aphezulu lapho ukusebenzisana phakathi kwezinto zemishini nezinsimbi zomhlaba eziyivelakancane kuqina, okuholela ekuncipheni kokungcola kwensimbi kanye nokuncipha kokuhlanzeka.Ngakho-ke, ukunciphisa izinga lokushisa lokunciphisa ngokuvamile kuyindaba esemqoka okufanele icatshangelwe ekwandiseni ukukhiqizwa kanye nokuthuthukisa ikhwalithi yomkhiqizo.
Ukuze unciphise izinga lokushisa lokunciphisa, kuyadingeka ukuthi uqale unciphise indawo yokuncibilika yemikhiqizo yokunciphisa.Uma sicabanga ukungeza inani elithile lephuzu elincibilikayo eliphansi kanye nezakhi zensimbi zomfutho womoya ophezulu njenge-magnesium ne-flux calcium chloride ezintweni ezinciphisayo, imikhiqizo yokunciphisa izoba yindawo encibilikayo ephansi engavamile yomhlaba i-magnesium intermediate alloy futhi encibilika kalula CaF2 · CaCl2 slag.Lokhu akugcini nje ukunciphisa kakhulu izinga lokushisa lenqubo, kodwa futhi kunciphisa amandla adonsela phansi akhiqizwe okunciphisa i-slag, okwenza kube lula ukuhlukaniswa kwensimbi ne-slag.I-Magnesium kuma-alloys ancibilikayo aphansi ingasuswa nge-vacuum distillation ukuze kutholakale okuhlanzekileizinsimbi zomhlaba ezingavamile.Le ndlela yokunciphisa, enciphisa izinga lokushisa lenqubo ngokukhiqiza ama-alloys aphakathi ancibilika aphansi, ibizwa ngokuthi indlela ye-alloy ephakathi ekusebenzeni futhi isetshenziswa kabanzi ekukhiqizeni izinsimbi zomhlaba ezingavamile ezinamaphoyinti aphezulu ancibilikayo.Le ndlela iye yasetshenziswa ekukhiqizeni izinsimbi isikhathi eside, futhi eminyakeni yamuva nje iye yenzelwe ukukhiqizwa kwensimbi.i-dysprosium, i-gadolinium, i-erbium, lutetium, terbium, scandium, njll.
