Aisafobe esiqhelekileyo sesokuba ukuba ioyile ligazi leshishini, umhlaba onqabileyo yivithamin yeshishini.
Umhlaba onqabileyo sisishunqulelo seqela leentsimbi. Izinto ezinqabileyo zomhlaba,REE) zifunyenwe enye emva kwenye ukusukela ekupheleni kwenkulungwane ye-18. Kukho iindidi ezili-17 ze-REE, kuquka i-lanthanides ezili-15 kwitheyibhile yeperiodikhi yezinto zemichiza-lanthanum (La), i-cerium (Ce), i-praseodymium (Pr), i-neodymium (Nd), i-promethium (Pm), njalo njaloOkwangoku, isetyenziswe ngokubanzi kwiinkalo ezininzi ezifana ne-electronics, i-petrochemicals kunye ne-metallurgy. Phantse yonke iminyaka emi-3 ukuya kwemi-5, izazinzulu zinokufumanisa ukusetyenziswa okutsha komhlaba onqabileyo, kwaye enye kuzo zonke izinto ezivelisiweyo ezintandathu ayinakohlulwa kumhlaba onqabileyo.
I-China izityebi ngezimbiwa zomhlaba ezinqabileyo, ibekwe kwindawo yokuqala kumazwe amathathu: elokuqala koovimba bemithombo, libalelwa kuma-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, i-China kuphela kwelizwe elinokubonelela ngeentlobo ezili-17 zesinyithi somhlaba esinqabileyo, ngakumbi umhlaba onqabileyo kunye nonzima onqabileyo kunye nesabelo esibalaseleyo somkhosi.
RUmhlaba ngumthombo oxabisekileyo weqhinga, owaziwa ngokuba yi "industrial monosodium glutamate" kunye "nomama wezinto ezitsha", kwaye isetyenziswa ngokubanzi kwisayensi neteknoloji kunye neshishini lomkhosi. NgokukaMphathiswa wezoShishino kunye neTekhnoloji yoLwazi, izinto ezisebenzayo ezinje ngemagnethi enqabileyo yomhlaba, i-luminescence, ukugcinwa kwehydrogen kunye ne-catalysis ziye zaba yimathiriyeli eyimfuneko kumashishini obugcisa obuphezulu njengokwenza izixhobo eziphambili, amandla amatsha kunye namashishini asakhulayo. isetyenziswa kakhulu kwi-electronics, i-petrochemical industry, i-metallurgy, oomatshini, amandla amatsha, imboni yokukhanya, ukhuseleko lokusingqongileyo, ezolimo njalo njalo. .
Kwango-1983, iJapan yazisa inkqubo yobuchule yokugcina izimbiwa ezinqabileyo, kwaye i-83% yomhlaba wayo onqabileyo wasekhaya wavela e-China.
Jonga eUnited States kwakhona, oovimba bayo bomhlaba onqabileyo bakwindawo yesibini emva kweTshayina, kodwa umhlaba wayo onqabileyo yimihlaba enqabileyo ekhanyayo, eyahlulahlulwe yaba yimihlaba enzima enqabileyo kunye nomhlaba onqabileyo okhanyayo. Umhlaba onzima onqabileyo ubiza kakhulu, kwaye umhlaba onqabileyo okhanyayo awunaqoqosho kum, oguqulwe waba yimihlaba enqabileyo yomgunyathi ngabantu abakushishino. I-80% ye-US enqabileyo yomhlaba ephuma ngaphandle ivela e-China.
UComrade uDeng Xiaoping wakha wathi: “KuMbindi Mpuma kukho ioli kunye nomhlaba onqabileyo eTshayina.” Intsingiselo yamazwi akhe iyabonakala. Umhlaba onqabileyo ayisiyiyo kuphela i-"MSG" efunekayo ye-1/5 yeemveliso zobuchwepheshe obuphezulu emhlabeni, kodwa kunye ne-bargaining chip ye-China kwitheyibhile yokuxoxisana yehlabathi kwixesha elizayo. Khusela kwaye usebenzise ngokwenzululwazi ubutyebi bomhlaba obunqabileyo, iye yaba sisicwangciso selizwe esibizelwe ngabantu abaninzi abaneembono eziphakamileyo kwiminyaka yakutshanje ukuthintela ubutyebi bomhlaba obunqabileyo obunqabileyo ukuba buthengiswe ngobumfama kwaye buthunyelwe kumazwe asentshona. Ngo-1992, uDeng Xiaoping wayichaza ngokucacileyo imeko yeTshayina njengelizwe elikhulu elinqabileyo lomhlaba.

Iscandiyam (Sc)
I-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, xa i-scandium kunye nezinto ezinqabileyo zomhlaba zixutywe kunye, i-scandium iya kudlula kuqala xa iphathwa nge-ammonia (okanye i-alkali ehlanjululwe kakhulu), ngoko inokwahlulwa ngokulula kwizinto ezinqabileyo zomhlaba ngendlela "yemvula eqhekezayo". 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, ukwenzela ukuba i-scandium ifakwe kwi-electrode ye-zinc, kwaye i-zinc ikhutshwe ukuze ifumane i-scandium. Ukongeza, i-scandium ifunyanwa ngokulula xa kusetyenzwa i-ore ukuvelisa i-uranium, i-thorium kunye ne-lanthanide element. Ukubuyiswa okubanzi kwe-scandium enxulumene ne-tungsten kunye ne-tin ore ikwangomnye wemithombo ebalulekileyo ye-scandium.ikwimeko ene-trivalent kwikhompawundi, ethi ifakwe ioksijini ngokulula ibe yi-Sc2O3 emoyeni kwaye iphulukane nokubengezela kwesinyithi kwaye ijike ibe ngwevu emnyama.
