Kusukela ngawo-1950s, amaShayinaUmhlaba ongavamileIzisebenzi zesayensi nezobuchwepheshe ziye zaqhuba ucwaningo olunzulu kanye nentuthuko kwindlela yokukhishwa kwe-solvent yokuhlukanisaUmhlaba ongavamileIzinto, futhi zithole imiphumela eminingi yocwaningo lwesayensi, esetshenziswe kabanzi ekukhiqizweni komhlaba okuvamile. Ngo-1970, i-N263 isetshenziswa ngempumelelo embonini ukuze ikhiphe futhi ihlukaniseytttrium oxideNgobumsulwa bama-99.99%, babuyisela indlela yokushintshaniswa kwe-Ion yokuhlukanisaytttrium oxide. Izindleko bezingaphansi kwengxenye yeshumi yaleyo ye-Ion Exchange indlela; Ngo-1970, ukukhishwa kwe-P204 kusetshenziswe esikhundleni sendlela yokuphindaphinda kabusha yokuba ngcono ukukhiqiza ukukhanyaI-Rare Earth Oxides; Ukukhishwalanthanum oxideusebenzisa i-methyl dimethyl hiptyl ester (P350) esikhundleni sendlela ye-clantacl crystallization ye-classical; Ngawo-1970s, inqubo ye-ammonia P507 ukukhishwa nokuhlukaniswa kweUmhlaba ongavamileizinto nokukhishwa kweytttriumnge-naphthenic acid yaqala ukusetshenziswa eChinaUmhlaba ongavamileImboni ye-hydrometurgy; Ukuthuthukiswa okusheshayo kobuchwepheshe bokukhishwa kweChinaUmhlaba ongavamileImboni ayihlukaniswa kusuka ekusebenzeni kanzima kwe-yuan chengye namanye ama-comrades aqhamuka eChina Academy of Sciences Scanghai Institute of Organic Chemistry. Ukukhishwa okuhlukahlukene (okufana ne-P204, i-P350, P507, njll.) Bacwaninge ngempumelelo ukuthi basetshenziswe kabanzi embonini; Umbono we-Cascade Extraction ehlongozwe futhi wagqugquzelwa nguSolwazi Xu Guangxian wePeking University ngeminyaka yo-1970s wadlala indima eqondisayo ekukhishweni nokuhlukaniswa kwe-China. Ngasikhathi sinye, inqubo yokuhlukanisa eyenziwe kahle kusetshenziswa i-theory ye-cascade ekhishwa futhi yasetshenziswa kabanzi kuUmhlaba ongavamileUmkhakha we-Extraction and Hartion.
Eminyakeni engama-40 edlule, iChina ithole izimpumelelo eziningi eziphawuleka emkhakheni weUmhlaba ongavamileukwahlukaniswa nokuhlanzwa.
Ngawo-1960, iBeijing Metals Metals Converment Institute yafunda ngempumelelo indlela yokunciphisa i-Zinc Powder ukukhiqiza ubumsulwa obukhuluI-Europuum Oxide, okwakungokokuqala eChina ukukhiqiza imikhiqizo enkulu kune-99.99%. Le ndlela isasetshenziswa kwezinhlobonhloboimihlaba engavamileezweni lonke elalisetshenziswa yifektri; Isitshalo samakhemikhali saseShanghai i-Youelong, iFudan University, kanye neBeijing General Institute ye-Nonferrous Metals basebenzisana nokuqala ukusebenzisa inqubo yokushintshana kwe-Ion ukucebisa i-N263 nge-P204 futhi yakhipha ubumsulwa bokuthola ubumsulwa be-99.95%ytttrium oxide. Ngo-1970, i-P204 yayisetshenziselwa ukucebisa i-N263 futhi itholeytttrium oxideNgobumsulwa be-99.99% ngaphezulu kwe-extraction yesibili nokuhlanzwa.
Kusukela ngo-1967 kuya ku-1968, isitshalo sokuhlola sefektri yaseJiangxi 801 kanye neBeijing bendels Metals Research Institute basebenzisana ngempumelelo inqubo yokusebenzisa i-P204 Extraction Groupting - I-N263 Extraction ukukhipha i-yttrium oxide. Ngo-December 1968, i-3-tow / unyaka y yytttrium oxideUkukhiqizwa kokukhiqizwa kwakhiwa, ngohlangowo lwama-99% weytttrium oxide.
Ngo-1972, kwasungulwa ithimba lokucwaninga yizinkampani ezine, kufaka phakathi i-Beijing Metals Metals Research Institute, i-Jiangxi 806 Factory, isikhungo sokucwaninga ngeMetallurgy, kanye ne-ChangSha Nonferous Metallurgy Design Institute. Ngemuva kweminyaka emibili yokuhlolwa kokucwaninga okuhlangene eBeijing Nonferrous Metals Researy Institute, inqubo yokukhiphaytttrium oxideUsebenzisa i-naphthenic acid njengotshwala obudonsayo noluxubekile njengoba nje kufundwe nge-dilient.
Ngo-1974, i-Changchun Institute yamakhemikhali asetshenzisiwe atholakele okokuqala lapho ehlukanisaUmhlaba ongavamileizinto zisebenzisa isizinda se-naphthenic acid,ytttriumyayitholakala phambi kweuhlobo linthanum, Kwenze kube yinto ekhishwe kalula ezindaweni ezinqabile zomhlaba. Ngakho-ke, ubuchwepheshe bokuhlukanisaytttrium oxideKuhlongozwe isizinda se-nafenic acid kusuka ku-nitric acid system. Ngasikhathi sinye, iBeijing Metals Metals Researy Institute yenziwe ucwaningo ngokwahlukana kweytttrium oxidekusuka ezinhlelweni ze-hydrochloric acid usebenzisa i-naphthenic acid, futhi kwaqhutshwa izivivinyo ezandisiwe eNanchang 603 Plant kanye ne-Jijiang 806 Plant ngo-1975, kusetshenziswa iLongnan exubekileEarth Earth Axidenjengento eluhlaza. Ngo-1974, iShanghai Youlong Chemical Plantram, iFudan University, kanye neBeijing izinsimbi zokucwaninga ngezinsimbi izikhungo zokucwaninga zisebenzisana nokufunda ukwahlukana kweytttrium oxidE kusuka eMonazite kuxutshweUmhlaba ongavamileonsunduytttriumUColumbium Ore Usebenzisa OkusindayoUmhlaba ongavamilekukhishwe futhi kuqoqwe yi-P204 njengento eluhlaza, futhiytttrium oxide uhlukaniswe isizinda se-nafenic acid. Umncintiswano wobungani wawubanjelwe emaflini amathathu, lapho wonke umuntu eshintshana khona ubuhlakani, wafunda emandleni nobuthakathaka bomunye nomunye, futhi ekugcineni wafunda ngempumelelo isizinda se-nafennenic acid kanye nenqubo yokuhlukanisa engu-99.99%ytttrium oxide ngezici zamaShayina.
Kusukela ngo-1974 kuya ku-1975, ifektri yaseNanchang 603 yasebenzisana neChAngchun Institute ye-Chemistry Chemistry, i-Berrous Metals, iJiangxi Institute of nonerrous metallurgy, namanye amayunithi ukutadisha ngempumelelo isizukulwane sesithathuytttrium oxidInqubo ye-e ye-Extraction - I-Naphthenic Acid One-Isinyathelo Socingo kanye nokukhishwa kobumsulwa obuphezuluytttrium oxide. Inqubo yafakwa ekusebenzeni ngo-1976.
Ezweni lokuqala lezweUmhlaba ongavamileInkomfa ye-Extraction ibanjelwe eBaotou ngo-1976, uMnu Xu Guangxian wahlongoza umbono wokukhishwa kwe-cascade. Ngo-1977, "i-National SymposiumUmhlaba ongavamileI-CASTACTION theory theory kanye nokuzilolonga "bekubanjelwe eShanghai Youlong Chemical Plant, ukuhlinzeka ngesingeniso esihlelekile futhi esibanzi kulo mbono. Kamuva, i-theory yokukhishwa kwe-cascade yasetshenziswa kabanzi ocwaningweni nasekukhiqizweni kokuhlukaniswa komhlaba okuvela emhlabeni.
Ngo-1976, iBeijing Metals Metals Researy Institute yasebenzisa iBaotou Ore exutshweUmhlaba ongavamileukukhiphaumrintshikusuka ezintweni ezicebile. Indlela ye-N263 Extraction yayisetshenziselwa ukuhlukanisauhlobo linthanum I-PraseOdDODYIUM needymium. Imikhiqizo emithathu yahlukaniswa ekukhishweni okukodwa, nobumsulwa belanthanum oxide, I-PraneOdymium oxide, futhineodymium oxidewayezungeze ama-90%.
Kusukela ngo-1979 kuya ku-1983, BaotouUmhlaba ongavamileIsikhungo Sokucwaninga kanye neBeijing Metals Researy Institute yathuthukisa uhlelo lwe-P507 Hydrochloric AcidUmhlaba ongavamileInqubo yokuhlukanisa ukuhlukaniswa kwe-Extraction isebenzisa iBaotou Rare Earth ORE njengento eluhlaza ukuthola okuyisithuphaUmhlaba ongavamileimikhiqizo (purity 99% kuya ku-99.95%) yeuhlobo linthanum, umrintshi, I-PraseOdDODYIUM, needymium, iSamurium, futhiigadiki, kanye neindlu yokuhlala yokungenayoguguna-i-terbiumimikhiqizo ecebisayo. Inqubo ibifushane, iyaqhubeka, futhi ubumsulwa bomkhiqizo buphakeme.
Ekuqaleni kweminyaka yama-1980s, iBeijing Metals Research Institute yahlanganyela ne-Jiujiang Metals Smelter, i-Changchun Institute of Servicer Chemistry, kanye ne-Jiangxi 603 efektri "uhlelo lwezinhlelo eziyisithupha" futhi athuthukise ngempumelelo ubuchwepheshe bezinqubo zokuhlukanisa ngokupheleleUmhlaba ongavamileizinto ezivela ku-Longnan ezixubekileUmhlaba ongavamileKusetshenziswa uhlelo lwe-P507 HYDROCHLORIC Acid System.
Ngo-1983, ama-Jiujiang angenzi lutho uSmelter amukele ubuchwepheshe be-Beijing bendels Metals Researy Institute "Naphthenic acid hydrochloric acid system ukukhiqiza ibanga le-fluorescentytttrium oxideUkusuka Emhlabeni Ongajwayelekile Okungajwayelekile "ukukhiqiza ibanga le-fluorescentytttrium oxide, ukunciphisa izindleko zeytttrium oxidenokuhlangabezana nesidingo seytttrium oxideNgethelevishini yombala eChina.
Ngo-1984, iBeijing General Institute of izinsimbi ezingezinhle zangempela zafunda ngempumelelo ukuhlukaniswa kobumsulwa obukhuluterbium oxideusebenzisa i-P507 Extraction Resin usebenzisai-terbiumukucebisa izinto njengezinto zokwakha eziluhlaza eChina.
Ngo-1985, iBeijing Metals Metals Research Institute idlulisela i-Nafthenic Acid Extraction Supporetion Pleorescent Greaderation Pradenceytttrium oxideUbuchwepheshe bobuchwepheshe ku-Republic yaseJalimane yeDemocratic yeDemocratic ngama-1.71 million ama-Swiss Franc, okwakuqalaUmhlaba ongavamileUbuchwepheshe benqubo yokuhlukaniswa okuthunyelwe yiChina.
Kusukela ngo-1984 kuya ku-1986, i-Peking University iphothulwe izivivinyo zezimboni ekukhishweni nasekwahlukanisweni kwe-LA / CEPR / ND ne-LA / CCL uhlelo lwe-P507-HCL ku-PSPS7-HCL System e-P507-HLS System e-P507-HLS System e-P507-HLS System e-P507-HCL ku-PBRED System elesithathuUmhlaba ongavamileIsitshalo se-baosteel. Bangaphezu kuka-98%I-PraneOdymium oxide, 99.5%lanthanum oxide, ngaphezu kwama-85%I-Cerrium Oxide, no-99%neodymium oxidebatholwa. Ngo-1986, isitshalo samakhemikhali samakhemikhali saseShanghai i-shadong sasebenzisa i-actimialing design them inqubomgomo emithathu yokukhipha, impumelelo ye-Peking University extruction theory, ukuqhuba ukuhlolwa kwezimboni ezintathu ezivela e-P077-HLS Syltem Lightrate Rate Rark Hark. Isikali sezimboni sandise ngokuqondile ukwandisa i-cascade ukukhishwa kwethiyori design kumathani ayi-100, kunciphisa kakhulu umjikelezo wokusebenzisa inqubo entsha yokukhiqiza.
Kusukela ngo-1986 kuya ku-1989, i-Baotou Rare Earth Research Institute, i-Beijing Metals Converment Institute yathuthukisa inqubo yokukhishwa kwe-P507-HLS HLS LULTELT Outlet, okuvumela ukukhiqizwa kwasikhathini kwemikhiqizo engu-3-5 emhlabeni jikelele. Inqubo imfushane, iyabiza, futhi iyavumelana nezimo.
Kusukela ngo-1990 kuya ku-1995, iBeijing Metals Metals Researy Institute kanye neBaotouUmhlaba ongavamileIsikhungo Sokucwaninga sisebenzisana nokwenza uhlelo lweNational "lwesishiyagalombili lweminyaka emihlanu" lwephrojekthi yesayensi kanye nezobuchwephesheUmhlaba ongavamileUbuchwepheshe bokukhishwa ". Ishumi nesithuphaEarth Earth AxideImikhiqizo enobumsulwa obukhulu kune-99.999% kuya ku-99.9999% balungiselelwe kusetshenziswa indlela yokukhipha, indlela ye-chromatography, i-redox indlela ye-fiber chromatography indlela, ngokulandelana. Le nqubo ifinyelele ezingeni eliphakeme lamazwe omhlaba futhi yanqoba uhlelo lweNational "lwesishiyagalombili lweNational Nearn" Plan "enkulu yokuphumelela.
Ngo-2000, iBeijing Metals Metals Researy Institute yathuthukisa ngempumelelo indlela yokunciphisa i-electrolytic yokunciphisa i-Alkality ukulungiselela ubumsulwa obuphezuluI-Europuum Oxide. Ngenxa yokugwema ukungcoliswa kwe-zinc powder emkhiqizweni, le nqubo ingakhiphaI-Europuum Oxidengobumsulwa be-5N-6N ku-One Go. Ngo-2001, umugqa wonyaka wokukhiqiza amathani angu-18 wobumsulwa obukhuluI-Europuum OxideYakhiwa eGansuUmhlaba ongavamileInkampani futhi isebenze kulo nyaka.
