Kugadzirira kwevanhu pasi renyika simbi
Kugadzirwa kwesimbi yepasi risingawanzo kunozivikanwa seKashoma Pasi Pyika PyrometaLurmical kugadzirwa.Risingawanzo nyika simbizvinowanzo kupatsanurwa mukuvhenganiswa kusasanganiswa pasi simbi uye imwe chete nyika simbi simbi. Kuumbwa kwekuvhengana kwevhu kwakasanganiswa kwakangofanana neyekutanga nzvimbo yekuumbwa kwepasi muOre, uye simbi imwechete isimbi yakaparadzaniswa uye yakanatswa kubva kune imwe neimwe nyika. Zvakaoma kuderedza nguva dzose yenyika (kunze kwenzara yeSamarium, Eurpeium, ytterbium, uye thulium) kuita simbi imwe ichishandisa nzira dzakawanda dzesimbi, nekuda kwekupisa kwavo kwakakwirira kwekuumbwa nekugadzikana kwakanyanya. Naizvozvo, izvo zvinowanzoshandiswa zvishandiso zvekugadzirwa kwekugadzirwa kwevanhu vasi pasi simbi uye fluorides.
(1) yakaumbwa yemunyu maElectrolysis nzira
Iko kugadzirwa kukuru kwesanganiswa pasisvike pasi masimbi muindasitiri kazhinji inoshandisa nzira yakaumbwa yemunyu magetsi. Iyi nzira inosanganisira kupisa nekunyungudika pasi rose seyakaisa pasi rose sevanhu pasi, uyezve magetsi kuti aonekwe pasi rose pasi simbi yekati. Kune nzira mbiri dzekusarudza magetsi: chloride electrolysis uye oxide electrolysis. Iyo yekugadzirira nzira yeimwe usingawanzo kusarudzika pasi simbi inosiyana zvichienderana nechinhu. Samarium, Euritorium, ytterbium, uye thuliamu haina kukodzera kugadzirira kweMagetsi nekuda kwekumanikidzwa kwemupfu wavo, uye panzvimbo pezvo zvakagadzirirwa kushandisa kudzikisira nzira yekudzikisa. Zvimwe zvinhu zvinogona kugadzirirwa nemagetsi kana simbi yekudzora maitiro ekudzikisa.
Chloride Electrolysis inonyanya kuzivikanwa nzira yekugadzira simbi, kunyanya yekuvhenganisa nyika isingasviki simbi. Maitiro acho ari nyore, anodhura-anoshanda, uye anoda mari shoma. Nekudaro, iyo hurukuro yakakura ndeyekusunungurwa kweClorine gasi, iyo inosvibisa nharaunda.
Oxide electrolysis haisunungure magasi anokuvadza, asi mutengo wakakwira zvishoma. Kazhinji, yakakwira mutengo usina kujairika nyika zvakaita se eodymium uye praseodymium inogadzirwa uchishandisa oxide extrolysis.
(2) vacuum thermal kuderedza nzira
Iyo nzira yemagetsi inogona kungogadzirira General Industrial Giredhi Rare Pasi Simbi Simbi. Kugadzirira simbi nekudzikira kwakaderera uye kuchena kwakanyanya, vacuum thermal kuderedza nzira inowanzo shandiswa. Kazhinji, over olation nyika inotanga kuitwa mune zvishoma pasi pasi, ayo akaderedzwa nesimbi calcium mune vacuum induction choto kuti vawane simbi isina kuchena. Zvadaro, ivo vanoremedzwe uye vanodzikira kuti vawane pure simbi. Iyi nzira inogona kuburitsa ese asina basa epasi simbi, asi Samarium, Eurppium, ytterbium, uye thutium haigone kushandiswa.
Iyo oxidation kuderedza kugona kweSamarium, Eurppium, ytterbium, thutiumuye calcium yakangodzora chikamu chevhu chakatanga kuderera. Kazhinji, aya masimbi akagadzirirwa nekushandisa musimboti wekumanikidza kukuru kweaya masimbi aya uye kusanganisa uye kupwanya mhou dzepasi pane marara emarara, uye kuderedza mune vira revaRuum. Lanthanamuinoshanda.Samarium, Eurppium, ytterbium, uye thuliamuinoderedzwa ne lanthanamu kuita goridhe uye inounganidzwa pane iyo condenser, iri nyore kupatsanura kubva ku slag.
