Okwangoku, kukho iindlela ezimbini eziphambili zokulungiselela i-industrial metallic calcium ekhaya nakwamanye amazwe: i-electrolysis kunye nokunciphisa i-thermal. Ingqwalasela yinkqubo, izixhobo kunye nenkqubela phambili ye-vacuum distillation yokulungiselela i-high-purity metallic calcium. I-Electrolysis kunye nokunciphisa i-thermal ziindlela zokuhlanjululwa kweekhemikhali ekunzima ukuLungisa i-calcium yensimbi ecocekileyo. Ukusebenzisa i-calcium yezoshishino njengezinto eziluhlaza, i-vacuum distillation ingasetyenziselwa ukulungisa i-calcium yensimbi ecocekileyo ngococeko olungaphezulu kwe-99.999% (5N).
Ngokwesiseko sophando lwangaphambili, iqondo lobushushu lokujiya lahlalutywa ngakumbi kwaye labalwa ngokwethiyori, kunye nesixhobo sokucoca i-calcium vacuum distillation yesinyithi esilungele ukuveliswa kweshishini sayilwa kwaye senziwe ngokwaso. Uphando lovavanyo kwizixhobo ezahlukeneyo zesixhobo lubonise ukuba udonga lwangaphakathi lwe-304 ye-tank yensimbi engenasici Emva kokufakwa kwe-chromium, inokunciphisa ngokufanelekileyo umphumo wezixhobo zokusebenza kwisiphumo sokucoca i-calcium yensimbi. Ukudibanisa neziphumo zophando lwangaphambili, emva kovavanyo lwe-distillation yesinyathelo esisodwa, ukucoceka kuphezulu njenge-99.99%, umxholo we-calcium osebenzayo uphezulu njenge-99.5%, kwaye umxholo wegesi uphantsi (C
