Dadaal ka badan 40 sano ka dib, gaar ahaan horumarka degdega ah ee tan iyo 1978-kii, Shiinahadhul dhif ahwarshaduhu waxay soo mareen horumar tayo leh oo heer wax soo saar ah iyo tayada wax soo saarka, samaynta nidaam warshadeed oo dhamaystiran. Hadda,dhul dhif ahsifaynta Shiinaha
Awoodda dhalaalidda iyo kala-soocidda macdanta waxay gaartaa in ka badan 130000 oo tan sannadkii (REO), wax-soo-saarka dhulalka dhifka ah ee sannadlaha ahi waxa uu gaadhaa in ka badan 70000 oo tan, taas oo ka dhigan in ka badan 80% wax-soo-saarka guud ee adduunka. Mugga wax-soo-saarkeeda iyo dhoofintiisa ayaa labaduba ah kuwa ugu weyn adduunka.
Waxaa jira in ka badan 170dhul dhif ahShirkadaha dhalaalidda iyo kala-soocidda ee Shiinaha, laakiin kaliya 5 ayaa leh awood wax-qabad sannadle ah oo ka badan 5000 oo tan (REO), iyadoo ganacsiyada intooda badani ay leeyihiin awood wax-qabad oo ah 1000-2000 tan.
Waqtigan xaadirka ah, Shiinuhu wuxuu sameeyay saddex saldhig oo wax-soo-saar oo waaweyn oo u badan ilaa saddex waaweyndhul dhif ahkhayraadka:
(1) Waqooyidhul dhif ahSaldhig wax-soo-saar ayaa la sameeyay iyadoo Baotou la isku daraydhul dhif ahore sida alaabta ceeriin, oo leh BaotouDhulka naadirHigh Tech iyo Shirkadda Gansu Rare Earth oo ah laf dhabarta. Waxaa jira in ka badan 80 shirkadood oo wax soo saaradhul dhif ahkiimikooyinka sidachloride dhul dhif ahiyo kaarboonaydh sannadkii
In ka badan 60000 tan oo xeryahooda ah iyo 15000 oo tan oo hal ahdhul dhif ahxeryahooda. Waqtigan xaadirka ah, inta badandhul dhif ahShirkadaha farsameeya macdanta Baotou waxay isticmaalaan habka dhalaalidda aashitada ee uu sameeyay Machadka Cilmi-baarista Biraha ee Beijing, ka dibna isticmaal P204 ama P507 soo saarista skala qaybsanaan, kuwaas oocerium nadiif ah oo sarreeyawaxaa guud ahaan soo saara soo saarista oksaydhaynta, iyo heerka fluorescenteuropium oxidewaxaa lagu soo saaraa soosaar dhimis. Alaabta ugu muhiimsan waxaa ka mid ah hal ama isku dhafan oo isku dhafan oo dhif ah oo dhulka ah sidalanthanum, cerium, praseodymium, neodymium, samaroon, europiumiwm.
(2) Mid dhexdhexaad ah iyo mid culusdhul dhif ahSaldhig wax-soo-saarku waxa uu qaataa macdano nooca ion-koofureed sida alaab ceeriin ah, waxana uu gacanta ku hayaa ku dhawaad 20000 oo tan oo ah nooca ionic ee koonfurtadhul dhif ahmacdanta sannadkii. Shirkadaha laf dhabarta waxaa ka mid ah Guanzhou the Pearl River Smelter, Jianyin JiahuaDhulka naadirWarshada, iyo Yixin Xinwei Rare Earth Co., Ltd Company, Liyan Luodiya Fangzheng Rare Earth Company, Guangdong Yanjiang Rare Earth Factory, iwm. Nooca ion koonfurta nooca dhif ah miinooyinka dhulka guud ahaan waxay isticmaalaan ammonium sulfate in goobta leaching carbonate roobka gubanaya hydrochloric acid disolu P507 iyo naphthenic kala saarista aashitada iyo nadiifinta.
Dhexdhexaad ilaa mid culusoksaydhyada dhulka naadiriyo qaar ka mid ah xeryahooda la hodmay sidayttrium, dysprosium, terbium, europium, lanthanum, neodymium, samarooniwm.
(3) Isticmaalka Mianning fluorocarbon cerium ore ee Sichuan sida walxo ceeriin ah, saldhig wax soo saar oo macdanta cerium-ka fluorocarbon ayaa laga sameeyay Sichuan. Hadda waxa jira 27 dhirta hydrometallurgy oo leh wadarta wax soo saarka sannadlaha ah ee 15-2000 tan. Habka dhalaalidda ee macdanta fluoride iyoceriummacdanta inta badan waxa ay ku lug leedahay oxidation dubay vNidaamyada daaweynta kiimikaad ee qallafsan oo ka soo jeeda habka ugu muhiimsan ee duban sulfuric acid leaching, iyada oo alaabtu ay yihiin hal ama isku-darka isku-dhafka dhulka dhifka ah ee inta badan ka koobanlanthanum, ceriumiyoneodymium. Inta badan ganacsiyadu waa kuwo aad u yar, oo leh qalab hooseeya iyo heerka tignoolajiyada.THalkan waxaa ku yaal alaabo badan oo aasaasiga ahdhul dhif ahAlaabada dhalaalaysa, oo leh nadiif sare iyo alaabada dhulku naadirka ah oo lagu qiyaasay in aanay ka badnayn 5%.
