Aisafobe esiqhelekileyo kukuba ukuba ioli ligazi loshishino, ngokoumhlaba onqabileyoyivithamin yoshishino.
Umhlaba onqabileyosisishunqulelo seqela leentsimbi.Umhlaba onqabileyoElements,REE) zifunyenwe enye emva kwenye ukusukela ekupheleni kwenkulungwane ye-18. Kukho iindidi ezili-17 ze-REE, kuquka i-lanthanides ezili-15 kwitheyibhile yeperiodi yezinto zemichiza-lanthanum(La),i-cerium(Ce),ipraseodymium(Pr),neodymium(Nd), ipromethium (Pm), njalo njaloOkwangoku, isetyenziswe ngokubanzi kwiinkalo ezininzi ezifana ne-electronics, i-petrochemicals kunye ne-metallurgy. Phantse yonke iminyaka emi-3-5, izazinzulu zinokufumanisa izinto ezintsha ezisetyenziswayo zomhlaba onqabileyo, kwaye enye kuzo zonke izinto eziye zaqanjwa ezintandathu ayinakwahlulwaumhlaba onqabileyo.
I-China ityebile kwiumhlaba onqabileyoizimbiwa, ezibekwe kwindawo yokuqala kumazwe amathathu: elokuqala koovimba bemithombo, libalelwa malunga nama-23%; Isiphumo sesokuqala, sithatha i-80% ukuya kwi-90% yezinto ezinqabileyo zehlabathi; Umthamo wentengiso yeyokuqala, kunye ne-60% ukuya kwi-70% yeemveliso zomhlaba ezinqabileyo ezithunyelwa kumazwe angaphandle. Kwangaxeshanye, iChina kuphela kwelizwe elinokubonelela ngeentlobo ezili-17 zesinyithi somhlaba esinqabileyo, ngakumbi esiphakathi nesinzima.imihlaba enqabileyongesabelo ezibalaseleyo zomkhosi use.China kaThixo inomona.
Rzisemhlabenisisixhobo sobuchule esixabisekileyo, esibizwa ngokuba yi "industrial monosodium glutamate" kunye "nomama wezinto ezintsha", kwaye sisetyenziswa ngokubanzi kwisayensi kunye neteknoloji kunye neshishini lomkhosi.

Kwangowe-1983, iJapan yazisa inkqubo yobuchule yokugcina izimbiwa ezinqabileyo, kunye ne-83% yasekhaya.imihlaba enqabileyoyavela eTshayina.
Jonga eUnited States kwakhona, yayoumhlaba onqabileyooovimba besibini kuphela eTshayina, kodwa yayoimihlaba enqabileyozonke zikukhanyaimihlaba enqabileyo, ezahlulwe zibe nzimaimihlaba enqabileyokunye nomhlaba onqabileyo okhanyayo. Inzimaimihlaba enqabileyozibiza kakhulu, kwaye ukukhanya komhlaba okunqabileyo akunamali kweyam, ejikwe yaba yinkohlisoumhlaba onqabileyos ngabantu abakushishino. I-80% yase-USumhlaba onqabileyoiimveliso ezivela ngaphandle zivela eTshayina.
UComrade uDeng Xiaoping wakhe wathi: “Kukho ioyile kuMbindi Mpuma kwayeimihlaba enqabileyoeTshayina." Intsingiselo yamazwi akhe iyabonakala. Umhlaba onqabileyo awuyomfuneko kuphela "MSG" kwi-1/5 yeemveliso eziphezulu zobuchwepheshe emhlabeni, kodwa kunye ne-bargaining chip enamandla ye-China kwitheyibhile yokuxoxisana yehlabathi Khusela kwaye usebenzise ngokwenzululwaziumhlaba onqabileyokwimithombo, iye yaba sisicwangciso sesizwe esibizelwa ngabantu abaninzi abaneembono eziphakamileyo kwiminyaka yakutshanje ukunqanda ixabisoumhlaba onqabileyoizibonelelo ezivela ekuthengisweni ngokungaboni kwaye zithunyelwe kumazwe asentshona. Ngo-1992, u-Deng Xiaoping wayichaza ngokucacileyo imeko ye-China njengento enkuluumhlaba onqabileyoilizwe.

Scandium(Sc)
Metal scandium(imephu yedatha)
Xa kuthelekiswa ne-yttrium kunye ne-lanthanide element, i-scandium ine-radius encinci ye-ionic kunye ne-alkalinity ebuthathaka ngakumbi ye-hydroxide. Ngoko ke, niniscandiumkunye nezinto ezinqabileyo zomhlaba zixutywa kunye,scandiumiya kudlula kuqala xa iphathwa ngeammonia (okanye idilute kakhulu ialkali), ngoko inokwahlulwa ngokululaumhlaba onqabileyoizinto ngendlela ye "fractional precipitation". Enye indlela kukusebenzisa i-polarization decomposition ye-nitrate yokwahlula.I-nitrate ye-scandium yeyona nto ilula ukubola, ngaloo ndlela ifezekisa injongo yokuhlukana.
I-Sc inokufunyanwa nge-electrolysis.I-ScCl3, i-KCl kunye ne-LiCl ziyanyibilika ngexesha lokucocwa kwe-scandium, kwaye i-zinc etyhidiweyo isetyenziswa njenge-cathode ye-electrolysis, ukuzescandiumi-precipitated kwi-electrode ye-zinc, kwaye i-zinc iyaphuphuma ukuze ifumanescandium.
