(1)Macdanta dhulka naadiralaabta
Khayraadka dhulka naadirka ah ee Shiinaha kuma koobna oo kaliya kayd badan iyo noocyo macdan oo dhammaystiran, laakiin waxa kale oo aad loogu qaybiyaa 22 gobol iyo gobollo dalka oo dhan ah. Waqtigan xaadirka ah, kaydka ugu weyn ee dhifka ah ee dhulka ee sida weyn loo qodayo waxaa ka mid ah Baotou isku-dhafka dhulka dhifka ah, ion adsorption naadirka dhulka oo ay matalaan Jiangxi iyo Guangdong, iyo macdanta fluorocarbon oo ay matasho Mianning, Sichuan. Isla mar ahaantaana, alaabada macdanta dhifka ah ee ugu weyn ayaa sidoo kale loo qaybiyaa saddex qaybood: fluorocarbon ore - monazite isku dar ah naadirka dhulka (Baotou rare earth concentrate), nooca ion koonfurta ee naadirka dhulka, iyo fluorocarbon ore (Sichuan mine)
(2) Alaabta birta ah ee la qasay
Warshadaha dhulka dhifka ah ee Shiinaha ayaa si isdaba joog ah u kobcaya, horumarka tignoolajiyada ayaa dardargelinaya, silsiladda warshaduhu si joogto ah ayay u fidaysaa, qaab-dhismeedka warshadaha iyo qaab-dhismeedka wax soo saarka ayaa si joogto ah u hagaajinaya. Hadda, waxay noqotay mid macquul ah. Nadiifinta sareeysa iyo alaabada dhifka ah ee dhulku waxay gaadheen in ka badan kala badh tirada guud ee badeecadaha, asal ahaan daboolaya baahiyaha suuqyada gudaha iyo dibadda. Sifeynta alaabta,oksaydhyada dhulka naadir waa alaabta ugu muhiimsan
Biraha dhulka naadirka ah iyo daawaha ayaa markii hore lagu isticmaali jiray warshadaha wax soo saarka birta iyo farsamada. Sannado badan, warshadaha birta dhulka ee dhifka ah ee Shiinaha waxay ku tiirsan yihiin kheyraadka dhulka ee dhifka ah, kharashyada wax soo saarka oo hooseeya, iyo horumarinta joogtada ah ee tignoolajiyada diyaarinta iyo tayada badeecada. Gaar ahaan sannadihii ugu dambeeyay, iyadoo baahida sii kordheysa ee suuqa codsiga alaabta, warshadaha birta ah ee dhifka ah ee dhulka ayaa si degdeg ah u horumaray wax soo saarkuna si degdeg ah ayuu u kordhay.
Laga soo bilaabo 1980-meeyadii, adeegsiga biraha naadirka ah ee goobta agabka naadirka ah ee shaqeynaya ayaa si degdeg ah u horumaray. Sanadihii 1990-meeyadii, iyada oo ay si degdeg ah u kor u kacday warshadaha macluumaadka elektaroonigga ah, soo saarista birta boron walxaha magnetka joogtada ah iyo agabka kaydinta hydrogen dhulka dhifka ah ayaa muujiyay koboc deggan.
Horumarka joogtada ah ee waxqabadka alaabta naadirka ah ee dhulka ayaa soo bandhigtay shuruudo sare oo loogu talagalay tayada alaabta birta ah ee dhifka ah sida alaabta ceeriin ee qalabka naadirka ah ee dhulka. Soo saarista walxaha naadirka ah ee kaydinta hydrogen waxay u baahan tahay isticmaalka biraha dhulka dhifka ah ee isku dhafan ee la soo saaray iyadoo la isticmaalayo nidaamka fluoride ee dhalaalay tignoolajiyada wax soo saarka milixda ee korantada oo leh nadiifnimo sare leh. Iyadoo balaadhinta joogtada ah ee goobta codsiga ee boron birta qalabka magnetka joogtada ah, birta ay diyaarisay habka dhimista kulaylka kaalshiyamka ayaa lagu beddelay birta iyo alwaaxyada cobalt oo ay soo saartay nidaamka fluoride ee dhalaalka ah ee electrolysis. Farsamada wax soo saarka milixda ee elektiroonigga ah ee nidaamka nitride ayaa si tartiib tartiib ah u noqotay tignoolajiyada caadiga ah ee soo saarista biraha dhifka ah ee dhulka iyo alwaaxyada loo isticmaalo walxaha naadirka ah ee dhulka shaqeeya.
(4) Alaabta kale
Waxaa jira noocyo badan oo kala duwan oo ah alaabooyin dhif ah oo dhulka ah oo leh adeegsi badan. Marka lagu daro alaabooyinka kor ku xusan, waxaa jira qalajiyeyaal naadir ah oo dhulka ah, daroogooyinka loo isticmaalo rinjiyada iyo dahaarka, xasiliyeyaasha dhulka dhifka ah iyo wax ka beddelka dhulka naadir, iyo wax ka beddelka gabowga ee caagadaha, naylon, iwm. Iyadoo horumarinta joogtada ah ee alaabta cusub ee dhifka ah ee dhulka. Baaxadda codsigooda ayaa sidoo kale sii fideysa, suuquna sidoo kale si joogto ah ayuu u sii fidayaa.
