Indlela yokunciphisa ukushisa kwe-calcium fluoride esetyenziselwa ukuveliswa kwenzimaiintsimbi zomhlaba ezinqabileyongokubanzi ifuna amaqondo obushushu aphezulu ngaphezu kwe-1450 ℃, nto leyo izisa ubunzima obukhulu ekuqhubeni izixhobo kunye nokusebenza, ngakumbi kumaqondo obushushu aphezulu apho unxibelelwano phakathi kwemathiriyeli yezixhobo kunye neentsimbi zomhlaba ezinqabileyo ziqina, okukhokelela ekunciphiseni ukungcoliseka kwesinyithi kunye nokuhla kobunyulu. Ngoko ke, ukunciphisa ubushushu bokunciphisa kudla ngokuba ngumba obalulekileyo omele uqwalaselwe ekwandiseni imveliso kunye nokuphucula umgangatho wemveliso.
Ukuze kuncitshiswe izinga lokushisa lokunciphisa, kuyimfuneko ukuba uqale unciphise indawo yokuncibilika kweemveliso zokunciphisa. Ukuba sicinga ukongeza umlinganiselo othile weqondo eliphantsi lokunyibilika kunye noxinzelelo oluphezulu lomphunga izinto zetsimbi ezifana ne-magnesium kunye ne-flux calcium chloride kwizinto ezinciphisa, iimveliso zokunciphisa ziya kuba yindawo ephantsi yokunyibilika enqabileyo yomhlaba i-magnesium intermediate alloy kwaye inyibilika ngokulula CaF2 · CaCl2 slag. Oku akugcini nje ukunciphisa kakhulu ubushushu benkqubo, kodwa kunciphisa ubunzima obuthile be-slag yokunciphisa eyenziwe, ehambelana nokuhlukana kwesinyithi kunye ne-slag. I-Magnesium kwi-alloys enyibilikayo ephantsi inokususwa nge-vacuum distillation ukuze ifumanekeiintsimbi zomhlaba ezinqabileyo. Le ndlela yokunciphisa, enciphisa ubushushu benkqubo ngokuvelisa i-alloys ephakathi enyibilikayo ephantsi, ibizwa ngokuba yindlela ye-alloy ephakathi ekusebenzeni kwaye isetyenziswa ngokubanzi kwimveliso yesinyithi yomhlaba enqabileyo eneendawo eziphezulu zokunyibilika. Le ndlela isetyenziswe kwimveliso yesinyithi ixesha elide, kwaye kwiminyaka yakutshanje iphuhliselwe ukuveliswa kwesinyithi.idysprosium, gadolinium, ierbium, lutetium, terbium, scandium, njl.
