Hadda,dhul dhif ahcanaasiirta waxaa inta badan loo isticmaalaa laba qaybood oo waaweyn: mid dhaqameed iyo mid sare.Codsiyada dhaqameed, sababtoo ah dhaqdhaqaaqa sare ee biraha dhifka ah ee dhulka, waxay nadiifin karaan biraha kale waxaana si ballaaran loogu isticmaalaa warshadaha birta.Ku darista oksaydhyada dhulka dhifka ah ee birta dhalaalaysa waxay ka saari kartaa wasakhda sida arsenic, antimony, bismuth, iwm soo saarista dhuumaha saliidda iyo gaaska.
Curiyayaasha dhulka naadirka ah waxay leeyihiin firfircooni firfircooni sare leh waxaana loo istcimaalaa dildilaaca batroolka ee warshadaha batroolka si loo hagaajiyo soosaarka saliidda iftiinka.Dhulka naadirka ah ayaa sidoo kale loo isticmaalaa sifeeyayaal katalytik ah oo loogu talagalay qiiqa baabuurta, qalajiyaha rinjiga, xasilinta kulaylka caaga ah, iyo soo saarista alaabada kiimikaad sida caag synthetic, dhogor macmal ah, iyo naylon.Ka faa'iidaysiga hawsha kiimikada iyo shaqada midabaynta ionic ee curiyeyaasha dhulka naadir, waxaa loo isticmaalaa warshadaha galaaska iyo dhoobada si ay u caddeeyaan dhalada, daalidda, midabaynta, midabaynta, iyo midabada dhoobada.Markii ugu horeysay ee Shiinaha, dhul dhif ah ayaa loo adeegsaday beeraha sida walxaha raadraaca ee bacriminta isku dhafan ee kala duwan, kor u qaadista wax soo saarka beeraha.Codsiyada dhaqameedyada, kooxda cerium kooxda naadirka ah ayaa inta badan la adeegsadaa, taasoo ka dhigan qiyaastii 90% wadarta guud ee curiyayaasha dhulka naadir ah.
Codsiyada teknoolojiyadda sare, sababtoo ah qaab-dhismeedka elektiroonigga ah ee gaarka ah eedhul dhif ah,Heerkooda kala duwan ee tamarta kala guurka elektarooniga ah waxay soo saaraan muuqaal gaar ah.Oksaydhyada eeyttrium, terbium, iyo europiumWaxaa si weyn loogu isticmaalaa sida fosfooraska cas ee telefishinnada midabka, hababka bandhigga ee kala duwan, iyo soo saarista saddex budo laambad ah midabka aasaasiga ah.Isticmaalka guryaha naadirka ah ee magnetic gaar ah si loo soo saaro magnets super joogto ah oo kala duwan, sida samarium cobalt magnets joogto ah iyo neodymium iron boron bir ah magnets joogto ah, waxay leedahay rajo codsiga ballaaran ee beeraha kala duwan ee farsamada sare sida matoor koronto, qalabka sawir-magnetic resonance nuclear, maglev. tareenada, iyo optoelectronics kale.Muraayadaha Lanthanum waxaa si weyn loogu isticmaalaa alaab ahaan muraayadaha kala duwan, muraayadaha, iyo fiilooyinka indhaha.Muraayada Cerium waxaa loo isticmaalaa sidii walxo shucaac u adkaysta.Dhalada Neodymium iyo yttrium aluminium garnet crystals-ka naadirka ah ee ka samaysan dhulka ayaa ah walxo muhiim ah oo dhegaha.
Warshadaha elektarooniga ah, ceramics kala duwan oo lagu daroneodymium oxide, lanthanum oxide, iyo yttrium oxide waxaa loo isticmaalaa sida qalab capacitor kala duwan.Biraha dhulka naadirka ah ayaa loo isticmaalaa in lagu soo saaro baytariyada nikkel haydarojiin lagu soo celin karo.Warshadaha tamarta atomiga, yttrium oxide waxaa loo isticmaalaa in lagu soo saaro ulaha xakamaynta ee reactors nukliyeerka.The alloy-fudud u adkeysiga kulaylka ka samaysan cerium kooxda dhif ah walxaha dhulka, aluminium iyo magnesium waxaa loo isticmaalaa in warshadaha aerospace si ay u soo saaraan qaybo ka mid ah diyaaradaha, dayaxgacmeedka, gantaalaha, gantaallada, iwm Dhulka dhif ah ayaa sidoo kale loo isticmaalaa in superconducting iyo qalabka magnetostrictive, laakiin tani dhinac weli waxay ku jirtaa marxaladda cilmi-baarista iyo horumarinta.
Heerarka tayada eeBir dhif ah dhulkaKhayraadka waxa ka mid ah laba dhinac: shuruudaha guud ee warshadaha ee kaydadka dhulka dhifka ah iyo heerarka tayada ee meelaha dhifka ah ee dhulka.Waxa ku jira F, CaO, TiO2, iyo Tfe ee ku jira fluorocarbon cerium ore concentrate waa in uu falanqeeyaa alaab-qeybiyaha, laakiin waa in aan loo isticmaalin saldhig ahaan qiimeynta;Heerka tayada ee isku-dhafka bastnaesite iyo monazite ayaa lagu dabaqi karaa xoogga la helay ka-faa'iidaysiga kadib.Waxyaabaha wasakhda ah ee P iyo CaO ee alaabta fasalka koowaad waxay bixiyaan oo kaliya xogta loomana isticmaalo saldhig qiimeyn ahaan;Isku-duubnaanta Monazite waxa loola jeedaa xoogga-ururinta macdanta ciidda ka dib ka faa'iidaysiga;Fosfooraska yttrium ore xooga waxa kale oo ay tilmaamaysaa xooga laga helay ka faa'iidaysiga macdanta ciidda.
Horumarinta iyo ilaalinta macdanta aasaasiga ah ee dhifka ah ee dhulka ayaa ku lug leh tignoolajiyada soo kabashada macdanta.Sabaynta, kala-soocidda cuf-jiidadka, kala-soocidda magnetic, iyo ka faa'iidaysiga habraaca la isku daray ayaa dhammaantood loo adeegsaday kobcinta macdanta dhulka naadir ah.Arrimaha ugu waaweyn ee saameeya dib-u-warshadaynta waxaa ka mid ah noocyada iyo xaaladaha dhacdooyinka curiyeyaasha dhulka dhifka ah, qaab-dhismeedka, qaab-dhismeedka, iyo sifooyinka qaybinta macdanta dhulka naadir ah, iyo noocyada iyo sifooyinka macdanta gangue.Farsamooyinka ka faa'iidaysiga ee kala duwan ayaa loo baahan yahay in lagu xusho iyadoo lagu salaynayo duruufo gaar ah.
Ka faa'iidaysiga macdanta aasaasiga ah ee naadirka ah ayaa guud ahaan qaata habka sabbaynta, oo inta badan lagu kabo cuf-isjiidadka iyo kala-soocidda birlabeedka, samaynta isku-darka cuf-isjiidadka sabbeynta, hababka kala soocidda magnetic flotation.Meelaha naadirka ah ee dhulka waxaa inta badan isugu soo ururay cuf-jiidadka, oo ay kaabayaan kala-soocidda birlabeedka, sabbaynta, iyo kala-soocidda korantada.Kaydinta macdanta birta ah ee dhifka ah ee Bayunebo ee gudaha Mongolia waxay ka kooban tahay monazite iyo fluorocarbon cerium ore.Xoog-saar dhul naadir ah oo ka kooban 60% REO waxaa lagu heli karaa iyadoo la adeegsanayo hab isku dhafan oo sabbeyn-dhaqid isku-dhafan oo kala soocida sabbeynta culeyska.Kaydinta dhulka naadirka ah ee Yaniuping ee Mianning, Sichuan waxay inta badan soo saartaa fluorocarbon cerium ore, iyo xooga dhul dhif ah oo ka kooban 60% REO ayaa sidoo kale la helay iyadoo la adeegsanayo habka sabbeynta sabbeynta culeyska.Xulashada wakiilada sabbeynta ayaa fure u ah guusha habka sabbeynta ee farsamaynta macdanta.Macdanta dhulka dhifka ah ee ay soo saarto miinada Nanshan Haibin ee Guangdong waxay u badan yihiin monazite iyo yttrium phosphate.Biyo-baxa laga helay maydhista biyaha qaawan waxa lagu sakhiray ka faa'iidaysiga wareegtada, oo ay ku xigto kala-soocidda cufis-jiidad, oo lagu kabo kala-soocidda magnetic iyo sabbaynta, si loo helo xooga monazite ah oo ka kooban 60.62% REO iyo fosphorite concentrate ka kooban Y2O5 25.35%.
