Kuleli sonto (7.4-7.8, okufanayo ngezansi), imikhiqizo emnyama futhi ekhanyayo yomhlaba emakethe yomhlaba engavamile ikhombisa ukuthambekela phansi, kanye nokwehla kwezinga lokukhanya komhlaba okuvamile kwakushesha. Amathuba ezomnotho ezinkulu eYurophu nase-United States ewela emculweni wezomnotho engxenyeni yesibili yonyaka asobala, futhi ama-oda athumelayo anokuhlangenwe nakho okusobala kokuthola imali. Yize ukunikezwa kwe-Upstream nakho kwehle, kuqhathaniswa nezinga elibuthakathaka kakhulu, kubukeka sengathi kusekhona okusele. Ukuphelelwa yithemba okuphelele kukhuphuke kuleli sonto, futhi umhlaba ongavamile futhi okhanyayo uwele esimweni esisobala sokubhidlizwa sokubhida.
Kuleli sonto, imikhiqizo ye-Prayeodymium kanye neNeodymium yaqhubeka nomkhuba ongezansi wesonto eledlule. Ngokuhoxiswa kwamabutho ahlukahlukene, ukufunwa kanye nokulindelwe okubuthakathaka, okuqhutshwa yingcindezi yokubhida, ijubane eliphansi eliphansi lamabhizinisi aphezulu asheshiswe kakhulu. Isinyathelo semakethe kwakuwumthengi, futhi intengo yokuthenga ishayisa okuphindaphindiwe ngenxa yethonya lezengqondo 'lokuthenga kodwa hhayi ukuthi lithenge phansi'.
Ethintwa yi-PrafeOdymium neNeodymium, isidingo seminye imikhiqizo esindayo yomhlaba eyindala nayo ibanda kakhulu, futhi imikhiqizo ye-gadolinium yehle kancane. Kodwa-ke, ngenxa yokwehla kancane ngentengo yezimayini zomhlaba ezinamandla, imikhiqizo ye-dysprosium ezinzile ekupheleni kwesonto eledlule, futhi yancipha kancane ngokuvumelanayo ngenxa yomthelela wesimo semizwa ephelele. I-Dysprosium Oxide iwele ngo-8.3% kusukela ngo-Ephreli. Ngokuphambene nalokho, inani eliphakeme lomlando lemikhiqizo ye-terbium ligcinwe isigamu sonyaka, kanye nokusetshenziswa kwawo wonke amaqembu eqoqweni lezimboni kuncishisiwe ngokwesaba amanani aphezulu nokungabaza. Kodwa-ke, ukukhuluma, isidingo seTerbium ezikhathini zamuva nje sithuthukile uma siqhathaniswa nesikhathi esedlule. Ivolumu yezimpahla ze-Bulk emakethe incane futhi kunezintengo eziphakeme kakhulu, ngakho-ke ukuzwela kwezindaba zemakethe kubuthakathaka kancane. Nge-terbium ngentengo yamanje, kungcono ukusho ukuthi kungaphansi kokulawulwa kwevolumu ephelele kunokuba kunwetshwe isikhala esisebenzayo kanye nesikhathi sokwehla kwamanani entengo ye-terbium, ngakho-ke uhla lwezemithwalo yemboni luphansi kunale dsprosium luphansi kakhulu kunale dsprosium liphansi kakhulu kunale dsprosium liphansi kakhulu kunale dsprosium.
Ngokombono wamanje we-macro, idola laseMelika liphule futhi lavuka. Ezinye izindaba zithi kwakuwukunciphisa ukuqina okuzayo e-United States, uhulumeni wase-US kulindeleke ukuthi aphumule amanani entela eChina, kanye nobhubhane ezingxenyeni eziningi zomhlaba zalwa emuva. Ngaphezu kwalokho, ubhubhane ezingxenyeni ezihlukene zezwe lwaphindwa, ngakho-ke imizwa ephelele yayingethemba. Ngokombono wezisekelo zamanje eziyisisekelo, ukwehla okusheshayo kwamanani entengo ezwe angavamile kubangele ukucindezela okuthile ekuthengeni okuphansi. Njengamanje, izinkomba zomhlaba wasekhaya ezingajwayelekile akulindelekile ukuba zikhule. Iningi lamabhizinisi abakhiqizi basekhaya lizogcwalisa ngenkuthalo yezinkomba kulo nyaka. Ama-oda wenhlangano ende aqinisekise ukufunwa okuphansi, futhi inani elincane lesidingo lingaholela ekubhide kakhulu.
