Ilaa iyo 1950-meeyadii, ShiinahaDhulka dhif ahShaqaalaha sayniska iyo tikniyoolajiyadda ayaa sameeyay cilmi baaris ballaaran iyo horumar xagga habka loo soo saaro xalkaDhulka dhif ahWaxyaabaha ay ka kooban tahay, oo ay gaareen natiijooyin cilmi baaris oo badan oo saynis ah, oo si weyn loogu adeegsaday wax soo saarka warshadaha dhulka ee dhif ah. Sanadkii 1970, N263 si guul leh ayaa loogu adeegsaday warshadaha si loo soo saaro oo kala soocoytrium okideoo daahir ah 99.99%, oo lagu beddelayo habka isdhaafsiga ion ee kala-soocaytrium okide. Qiimaha wuxuu ka yaraa mid toban meelood meel meel ka mid ah habka isdhaafsiga ee ion; Sanadkii 1970, soosaarka P204 ayaa loo isticmaalay halkii laga isticmaali lahaa habka dib-u-eegista caadiga ah si loo soo saaro iftiindibiyo kacsan dhulka; Soo saaristaLanthanum OgideIsticmaalidda methyl damiskyl Heerkul (P350) halkii laga isticmaali lahaa habka qiimeynta jajabyada ee caadiga ah; Sannadihii 1970-yadii, geedi socodka soo saarista amooniya p507 iyo kala taggaDhulka dhif ahwalxaha iyo soo saaristaytriumIyada oo Nafthenic acid ayaa markii ugu horeysay loo adeegsaday ShiinahaDhulka dhif ahhydrometaldurgy wershadaha; Horumarinta deg-degga ah ee tikniyoolajiyadda soo saarista ee ShiinahaDhulka dhif ahWarshadaha lagama sooci karo shaqada adag ee Yuan Chengye iyo saaxiibada kale ee ka soo jeeda Akademiyada Shangihii Shanghai Machadka Ururka dabiiciga ah. Soosaarayaasha kala duwan (sida P204, P350, P507, iwm.) Waxay si guul leh baa u baaray inay si weyn loo isticmaalay warshadaha; Fikradda soosaarka ee Cascade ayaa soo jeedisay oo ay dalacsiisay Professor xi gugangxian ee jaamacadda Peking 1970-yadii ayaa door ku yeeshay Tilmaanta Tilmaanta Shiinaha iyo Tiknocsiga Kala-goynta Shiinaha. Isla mar ahaantaana, geeddi-socodka kala go'idda ayaa lagu hagaajiyey iyadoo la adeegsanayo aragtida soo-saarista soosaarka ee Cascade la soo jeediyay oo si ballaaran loogu dabaqayDhulka dhif ahSoo saarista iyo warshadaha kala go'ida.
40-ka sano ee la soo dhaafay, Shiinaha ayaa gaadhay guulo badan oo cajiib ah oo ku saabsan garoonkaDhulka dhif ahkala tagga iyo nadiifinta.
Sannadihii 1960-yadii, Machadka Cilmi-baarista Bilood ee Beijing wuxuu si guul leh u bartay yareynta qaabka zinc budada ah si loo soo saaro daahirEuropejis, oo ahayd markii ugu horreysay ee Shiinaha si loo soo saaro alaabooyinka ka badan 99.99%. Qaabkan ayaa wali loo isticmaalaa waxyaabo kala duwanDhul dhif ahdalka oo dhan ee ay adeegsadeen warshadda; Warshadda kiimikada ee Shanghai yuuuulung, Jaamacadda Fudung, iyo Machadka Guud ee Beeraha Guud ee La'aanta ayaa kaashadaya in la isticmaalo geedi socodka soo saarida ion si ay u soo saarto P2063 oo ay soo saarto oo nadiifi si ay u helaan daahirnimo 99.95% daahirnimoytrium okide. Sanadkii 1970, P204 waxaa loo isticmaalay in lagu kobciyo N263 oo uu heloytrium okideIyada oo daahir ah oo ka badan 99.99% iyada oo loo marayo soosaarka labaad iyo nadiifinta.
Laga soo bilaabo 1967 ilaa 1968, geedka tijaabada ah ee Jiangxi 801 warshad warshadeed oo aan laheyn oo kaashacey si guul leh lagu baro habka loo adeegsado soo saarista soo saarista P204 - Soosaarka N226 Bishii Diseembar 1968, 3-ton / Sanad Yytrium okideAqoon-isweydaarsiga wax soo saarka ayaa la dhisay, iyadoo daahir ah oo ah 99% eeytrium okide.
Sanadkii 1972, koox cilmi baaris ah ayaa laga sameeyay afar shirkadood, oo ay ku jiraan Machadka Cilmi-baarista Bilood ee Laydhka ah, Jiangxi 806 warshad, Jiangxi noncerrus Machadka, iyo Changsha Hantresrugy Models Machadka. Laba sano ka dib tijaabooyin wadajirka ah ee cilmi-baarista wadajirka ah ee Machadka Cilmi-baarista Bilood ee Beenta ah, geedi socodka soo saaristaytrium okideAdeegsiga naphthenic acid sidii wax soo-saar oo isku dhafan oo ah in si guul leh loo bartay.
Sanadkii 1974, Machadka Checkchuran ee kimistariga ee la ogaadey markii ugu horreysay markii la kala soocayoDhulka dhif ahWaxyaabaha ku saabsan soo saarida asiidhka ee Naphthenic,ytriumwuxuu ku yaal horeLanthanum, taasoo ka dhigeysa waxyaabaha ugu fudud ee aan laga saari karin waxyaabaha ku jira qaybaha dhulka. Sidaa darteed, tikniyoolajiyad loogu talagalay kala-goyntaytrium okideIsticmaalka soo saarida aashitada ee Nafthenic ee nidaamka nitric acid ayaa la soo jeediyay. Isla mar ahaantaana, Machadka Cilmi-baarista Bilood ee Laydhka ah ee Beijing ah ayaa lagu sameeyay cilmi baaris ku saabsan kala soocaytrium okideNidaamyada acid hydrochloric acid iyadoo la adeegsanayo aashitada naphthenic acid, iyo tijaabooyin ballaadhan oo la ballaariyey waxaa lagu sameeyay Nanchang 603 warshad iyo Jiujiang 806, iyadoo la adeegsanayo Longnan isku dhafanDhulka oo dhif ah oxidesida shey ceyriin ah. Sanadkii 1974, Jaamacadda Shanghai yuuuuuuuuuuuluelg warshad, Jaamacadda Fudun, iyo Machadka Cilmi-baarista ee birta ee Beijing oo kaashanaa si loo barto kala-goyntaytrium oksiide ka imanaya monazite isku dhafanDhulka dhif ahee bunniytriumColumbum ore waxay isticmaashaa culusDhulka dhif ahWaxaa soo saaray oo ay kooxdu u soo saareen P204 sida qalabka cayriin, iyoytrium oksiide waxaa u kala soocaya soo saarista asiidh ee Nafthenic. Tartan saaxiibtinimo ayaa lagu qabtay seddex weji, halkaas oo qof walbaa wax laga beddelo, midba midka kale wuxuu ka bartay awooda iyo daciifnimadiisa, ugu dambeyntiina waxay si guul leh u bartay geedi socodka soo saarista asiidhthenic-ka Nafthenic iyo 9.99%ytrium oksiide oo leh astaamaha Shiinaha.
Laga soo bilaabo 1974 ilaa 1975, Nanchang 603 Warshadda uu ka shaqeynayay Machadka Checkcun ee Checkchury, Machadka Guud ee Bilaalka ah, Machadka Jangcxi ee Maskaxda Maskaxda, iyo cutubyo kale oo si guul leh u bartaan qarnigii saddexaadytrium oksiidHabka soo saarista - Nafeephenic acid-ka-soo-saaridda hal-tallaabo iyo soo saarida daahirka sareytrium oksiide. Hawsha waxaa la socday 1976.
Qaranka ugu horeeyaDhulka dhif ahShirka soo saarista ee lagu qabtay Baotou sanadkii 1976, Mr. X Gu'angxian wuxuu soo jeediyay aragtida soo saarista xerada. Sanadkii 1977, "Dan-dhaqameedka Qaranka eeDhulka dhif ahSoo-saarista fikradaha iyo waxqabadka "waxaa lagu qabtay Shanghai yuuuuuuuuuulung ee kiimikada, iyagoo bixinaya qaab nidaamsan oo dhameystiran oo ku saabsan aragtidan. Intaa ka dib, aragtida soo saarista soosaarka ee dhismaha ayaa si ballaaran loogu dabaqay cilmi baarista iyo soo saarista soo saarista dhulka ka soo baxa ee Dhulka Dhulka Dhulka ee Dhulka Kala-goynta iyo nadiifinta.
Sanadkii 1976, machadka cilmi baarista biraha ee Beijing birta ah ee loo adeegsado batoouou isku qasanDhulka dhif ahsi loo soosaarodaloollaga soo bilaabo sheyga la qalay.
