Phakathi kuJanuwari 2026, iJapan yathumela inqanawa yokugrumba yesayensi yolwandle olujulileyo i-"Chikyu" kwiSouth Bird Island ekude kuLwandlekazi lwePasifiki ukuze iqhube "isicwangciso sokuqala sokukhupha umhlaba onqabileyo olwandle olujulileyo". UShi Xuefa, umphandi kwiFirst Institute of Oceanography yeSebe leMithombo yeNdalo kunye nomlawuli weKey Laboratory of Marine Geology and Mineralization yeSebe leMithombo yeNdalo, ubonise kwiphepha lakhe ukuba iTshayina lelona lizwe likhulu kwihlabathi ngokubhekiselele kumhlaba, imveliso, ukusetyenziswa kunye nokuthunyelwa kwamanye amazwe kwezixhobo zomhlaba onqabileyo. Ukufunyanwa kwezixhobo zomhlaba onqabileyo olwandle olujulileyo kuzisa umngeni kwisikhundla seTshayina njengelizwe elikhulu lezixhobo zomhlaba onqabileyo elisekelwe emhlabeni.
Iindleko zokubuyisa nokuthutha udaka olunqabileyo, kunye neemfuno zobugcisa zokufezekisa uphuhliso olukhulu, nazo ziyimiba enzima etafileni. Ekubeni lo msebenzi ufuna ukubuyisela udaka olusezantsi kolwandle kwaye lukude nomhlaba, iindleko zokuthutha ezifanayo nazo ziya kwanda. Ukongeza, kukho umahluko phakathi kodaka olunqabileyo lolwandle olunzulu kunye nezinto eziluhlaza ezimbiwa emhlabeni, kwaye ubuchwepheshe bokucoca obuhambelanayo abukaphuhliswa ngokupheleleyo. Ngenxa yeempawu zeekhemikhali ezifanayo kakhulu zezinto ezili-17 zomhlaba onqabileyo, ukwahlula kunye nokucoca kufuna ikhemistri ephucukileyo nechanekileyo. Umzekelo, kufuneka ubuncinane amanyathelo angama-200 ukwahlula izinto ezifunekayo kusetyenziswa i-solvent extraction.
Umzekelo, i-oxide lanthanum (iLanthanum Oxide, ifomyula yekhemikhali iLa₂O₃, iCAS: 1312-81-8) eveliswe yiWONAIXI yi-oxide yomhlaba enqabileyo ephambili kwizinto ezintsha ezinqabileyo zomhlaba. Ngenxa yeempawu zayo ezizodwa zokukhanya, i-catalytic kunye nombane, iye yaba yinto esisiseko ebalulekileyo kwimveliso ephezulu kunye nobuchwepheshe bemida. Kwiminyaka yakutshanje, ngophuhliso olukhawulezayo lwamandla amatsha, ulwazi lwe-elektroniki kunye namashishini okukhusela okusingqongileyo, umda wokusetyenziswa kwe-oxide lanthanum uye wanda ngokuqhubekayo, ubonisa amandla amakhulu emarike kunye nexabiso lobuchwepheshe. Okwangoku, iWONAIXI ifezekise imveliso enkulu ye-high-purity oxide lanthanum ngokusebenzisa ubuchwepheshe obuphambili obufana nobuchwepheshe obahlukeneyo bepatent, ukuxhasa izalathisi ezenzelwe wena kunye nokukhuthaza ukwandiswa kwekhonkco lemizi-mveliso ukusuka ekutsalweni kwezixhobo ukuya kwiimveliso ezinexabiso eliphezulu.
IJapan lelinye lamazwe asebenza kakhulu kwicandelo lezemigodi elwandle olunzulu. Nangona kunjalo, iJapan ikwajongene nemida emininzi ekuphunyezweni kwesicwangciso sayo esiphambili sezemigodi. ITshayina iseke uthotho olukhulu lweshishini le-rare earth kwiminyaka embalwa nje, iqokelela isiseko sobugcisa esinzulu kwaye inexabiso eliphezulu kakhulu lemveliso. Oku akufezekiswa ngobusuku obunye. Xa kujongwa ukuba amandla okucocwa nokucubungula umhlaba onqabileyo kwihlabathi liphela agxile kakhulu eTshayina, nokuba iJapan iphumelela ekumbeni izinto ezikrwada, iya kuxhomekeka kakhulu kwiinkqubo zokucubungula zangaphandle.
