Izinto ezinqabileyo zomhlaba zihlala zivela kuluhlu lwezimbiwa ezicwangcisiweyo, kwaye oorhulumente kwihlabathi jikelele bayazixhasa ezi mveliso njengomcimbi womdla wesizwe kunye nokukhusela imingcipheko emandla.
Kule minyaka ingama-40 idlulileyo yenkqubela phambili yetekhnoloji, izinto zomhlaba ezinqabileyo (REEs) ziye zaba yinxalenye yenani elibanzi nelikhulayo lezicelo ngenxa yepropathi yazo yesinyithi, imagnethi kunye nombane.
Intsimbi ekhazimlayo yesilivere-emhlophe ixhasa ishishini lobugcisa kwaye ibalulekile kwikhompyutha kunye nezixhobo ezibonwayo, kodwa ikwasetyenziswa ngokubanzi kwialloyi kushishino lweemoto, iiglasi, umfanekiso wezonyango kunye nokucokisa i-petroleum.
Ngokutsho kwe-Geoscience Australia, iintsimbi ezili-17 ezichazwe njengezinto ezinqabileyo zomhlaba, eziquka izinto ezifana ne-lanthanum, i-praseodymium, i-neodymium, i-promethium, i-dysprosium kunye ne-yttrium, azinqabile ngokukodwa, kodwa ukutsalwa kunye nokulungiswa kwenza kube nzima ukuzifumana kwinqanaba lezorhwebo .
Ukusukela ngeminyaka yee-1980s, iChina ibilelona lizwe livelisa izakhi zomhlaba ezinqabileyo, ukodlula amazwe ovimba amandulo anjengeBrazil, iIndiya neUnited States, awayengamacandelo aphambili okusetyenziswa ngokubanzi kwezinto ezinqabileyo zomhlaba emva kokuvela koomabonakude bemibala .
Njengeentsimbi zebhetri, izitokhwe zomhlaba ezinqabileyo zibone i-boom yamva nje ngezizathu ezibandakanya:
Izinto ezinqabileyo zomhlaba zithathwa njengezimbiwa ezibalulekileyo okanye ezicwangcisiweyo, kwaye oorhulumente behlabathi jikelele bayandisa ukhuseleko lwezi mveliso njengombandela womdla wesizwe.Isicwangciso-qhinga sikaRhulumente wase-Australia seZimbiwa eziBalulekileyo ngumzekelo.
Abasebenzi basezimayini abanqabileyo base-Australia babenekota kaMatshi exakekileyo. Apha, sijonga into abayenzayo - apho -- kunye nendlela abaqhuba ngayo.
I-Kingfisher Mining Ltd (ASX:KFM) ifumene izinto ezibalulekileyo zomhlaba ezinqabileyo kwiprojekthi yayo ye-Mick Well kummandla we-Gascoyne e-Washington State, kunye ne-12 yeemitha ze-oxides zomhlaba ezinqabileyo (TREO) zizonke ziyi-1.12%, apho i-4 yeemitha zomhlaba onqabileyo Iyonke. Isixa seeoksidi sasiyi-1.84%.
Ukulandelela ukugrumba kumbono we-MW2 kucwangciselwe ukuqalisa emva kwekota, kujoliswe kwiithagethi ezongezelelweyo zeREE ngaphakathi kwepaseji ye-54km.
Ulwandiso olusentshona lwepaseji ekujoliswe kuyo ye-REE yanikezelwa ngezindlu nje emva kokuba ikota iphelile, inyathelo elibalulekileyo phambi kophando olucwangcisiweyo lwe-aeromagnetic neradiometric eyilelwe indawo.
Inkampani ikwafumene iziphumo zangaphambili zokugrumba eMick Well ngoMatshi, kubandakanywa i-4m kwi-0.27% ye-TREO, i-4m kwi-0.18% ye-TREO kunye ne-4m kwi-0.17% ye-TREO.
Umsebenzi wasendle uyathembisa, uchonga iseti yokuqala yongenelelo lwekhabhonitite ezisixhenxe ekwaziwa ngokunxulunyaniswa ne-REE mineralization.
Ngethuba lekota kaMatshi, i-Strategic Materials Australia Ltd. yagqiba ukwakhiwa kwezakhiwo kunye nezibonelelo kwi-Korea Metal Works (KMP), eyabhaliswa ngokusemthethweni.
Ufakelo kunye nokugunyaziswa kwesigaba sokuqala se-KMP kuya kuqhubeka ngekota, kunye nomthamo ofakelweyo weetoni ezingama-2,200 ngonyaka.
I-ASM ihleli izibophelele ekuqhubeleni phambili inkxaso-mali yeprojekthi yaseDubbo. Ngexesha lekota, ileta yenjongo evela kwi-inshurensi yorhwebo yaseKorea i-K-Sure yamkelwa ukubonelela i-ASM ngenkxaso ye-inshurensi ye-inshurensi enokubakho ukuxhasa uphuhliso lweprojekthi.
Ukulandela uphononongo lokuphucula olwenziwa ngoDisemba wonyaka ophelileyo, inkampani yangenisa ingxelo yohlengahlengiso kwiprojekthi yaseDubbo kurhulumente we-NSW, ebandakanya ukucwangciswa okucetywayo kunye nokuphuculwa koyilo.
Utshintsho lwebhodi ngexesha lekota lubandakanya umhlala-phantsi ka-Ian Chalmers ongengoyesigqeba osebenze ixesha elide, ubunkokeli bakhe bungundoqo kwiProjekthi Dubbo, kwaye bamkele i-FAICD kaKerry Gleeson.
I-Arafura Resources Ltd ikholelwa ukuba iprojekthi yayo ye-Nolans ihambelana kakhulu kunye nesicwangciso sikarhulumente we-federal ye-2022 isicwangciso esibalulekileyo samaminerali kunye nesicwangciso sohlahlo lwabiwo-mali, echaza ukunyuka okuqhubekayo kwexabiso le-neodymium kunye ne-praseodymium (NdPr) ngexesha lekota, elibonelela ngokuzithemba kuqoqosho lweprojekthi.
Inkampani ifikelela kubathengi baseKorea abafuna ukukhusela izixhobo zexesha elide ze-NdPr kwaye isayine ingxelo edibeneyo yentsebenziswano neKorea Mine Remediation kunye neMineral Resources Corporation.
Ngexesha lekota, inkampani ibhengeze ukuqeshwa kwe-Société Generale kunye ne-NAB njengabaququzeleli abakhokelayo abagunyazisiweyo ukuba baqhube i-arhente yetyala eliqhutywa yi-arhente yokuthumela ngaphandle iqhinga lokuxhasa imali. Hatch ngokweshedyuli yeArafura.
Le nkampani inethemba lokuba isibonelelo semali ezizigidi ezingama-30 zeerandi phantsi kwenyathelo likarhulumente leModern Manufacturing Initiative siza kunceda ekwakheni umzi-mveliso onqabileyo wokwahlula umhlaba kwiprojekthi yaseNolan.
Umsebenzi wasebaleni kwiprojekthi ye-PVW Resources Ltd's (ASX:PVW) yeTanami Gold kunye neRare Earth Elements (REE) iye yaphazanyiswa lixesha leemvula kunye nenani eliphezulu leemeko ze-COVID, kodwa iqela lokuhlola lithathe ixesha lokugxila kwizinto ezifunyanisiweyo zemineralogy, umsebenzi wovavanyo lwesinyithi kunye noCwangciso luka-2022 lwenkqubo yokomba yokuhlola yonyaka.
Amagqabantshintshi ekota aquka iisampulu ezintlanu zesinyithi ezinobunzima obuya kutsho kuma-20 kg ezibuyisela udidi lwezimbiwa phezu komphezulu owomeleleyo ukuya kuthi ga kwi-8.43% ye-TREO kunye neesampulu zesinyithi ezikwi-avareji yama-80% ebunzima obunqabileyo be-earth oxide (HREO), kubandakanywa i-avareji yeengxenye ezingama-2,990 ngesigidi (ppm) Dysprosium oxide kunye nokuya kuthi ga kwi-5,795ppm ye-dysprosium oxide.
Zombini iimvavanyo zokuhlela intsimbi kunye nokwahlula imagnethi zibe yimpumelelo ekunyuseni umgangatho wesampulu ezinqabileyo ngelixa zikhatywa inani elikhulu leisampulu, ebonisa ukonga okunokubakho kwiindleko zokusetyenzwa komsinga.
Isigaba sokuqala seprogram yokomba ka-2022 yi-10,000 yeemitha zokujikeleza umva (RC) kunye ne-25,000 yeemitha zokugrumba i-hollow core.
INorthern Minerals Ltd (ASX:NTU) iqukumbele uphononongo lobuchule kwikota kaMatshi, igqibe kwelokuba ukuveliswa kunye nokuthengiswa komhlaba onzima onqabileyo oxubeneyo ugxile kwiplanti ecetywayo yeBrowns Range yokusetyenzwa kwesikali sorhwebo yinkqubo yayo ekhethwayo ekufutshane .
Ucazululo olongezelelweyo lokugrumba olubuyisiweyo ngekota lubonise amathuba eZero, iBanshee kunye neRockslider, kunye neziphumo ezibandakanya:
I-Krakatoa Resources Ltd (i-ASX: i-KTA) ixakeke kwiprojekthi ye-Mt Clere e-Yilgarn Craton, e-Western Australia, apho inkampani ikholelwa ukuba iqulethe ithuba elibalulekileyo le-REE.
Ngokukodwa, izinto ezinqabileyo zomhlaba kucingelwa ukuba zikhona kwisanti ye-monazite echongiweyo ngaphambili exhaphakileyo egxininiswe kuthungelwano lwemijelo ye-tenure yasemantla, kunye nakumacandelo asezantsi agcinwe kwi-gneiss ion adsorption kudongwe.
Amatye e-carbonate atyebile ngeREE anxulunyaniswa nephondo elingummelwane leMt Gould Alkaline nawo anokubakho.
Le nkampani ifumene iitayitile zemihlaba emitsha ebalulekileyo eziikhilomitha ezingama-2,241 kwiprojekthi yeRandi, ekholelwa ukuba kulindeleke ukuba ibambe iiREE kudongwe olufana nezo zifumaneka kwiRand Bullseye.
Inkampani yagqiba ikota ngesithuba semali ye-730,000 yeedola kwaye yavala i-5 yezigidi zeerandi zenkxaso-mali ekhokelwa yi-Alto Capital emva kwekota.
Kule kota, i-American Rare Earths Ltd (i-ASX: i-ARR) isebenzisana nemibutho yophando yase-US ehamba phambili ukuba igxininise kubuchwepheshe obutsha obuzinzileyo, ukukhutshwa kwe-bio-based, ukwahlukana kunye nokucocwa komhlaba onqabileyo.
Ukuqhubela phambili ukongeza i-170 yezigidi zeetoni zemithombo ye-JORC njengoko bekucwangcisiwe kwiprojekthi yenkampani ephambili iLa Paz, apho iilayisenisi zokomba zivunyiweyo kwindawo entsha yeprojekthi esemazantsi-ntshona ekujoliswe kuyo kuqikelelo lwe-742 ukuya kwi-928 yezigidi zeetoni, 350 ukuya kwi-400 TREO, eyi-TREO. ukuncedisana neSibonelelo esikhoyo kwizixhobo zeJORC.
Ngeli xesha, iprojekthi ye-Halleck Creek kulindeleke ukuba iqulethe izibonelelo ezininzi kune-La Paz. Malunga ne-308 ukuya kwi-385 yezigidi zeetoni ze-REE mineralized rock zachongwa njengeenjongo zokuhlola, kunye ne-avareji ye-TREO amabakala ukusuka kwi-2,330 ppm ukuya kwi-2912 ppm. Iilayisensi zivunyiwe kunye nokugrunjwa. yaqala ngoMatshi ka-2022, kwaye iziphumo zokomba zilindeleke ngoJuni ka-2022.
I-American Rare Earths igqibe ikota ngemali eyi-8,293,340 yeedola kwaye ibambe izigidi ezi-4 zezabelo zeCobalt Blue Holdings ezixabisa malunga nezigidi ezi-3.36 zeedola.
Utshintsho lwebhodi lubandakanya ukuqeshwa kukaRichard Hudson kunye noSten Gustafson (US) njengabalawuli abangekho kwisigqeba solawulo, ngelixa uNoel Whitcher, igosa eliyintloko lemali yenkampani, eqeshwe njengonobhala wenkampani.
