Ukususela ekuphunyezweni komjikelo omtsha wempumelelo kwisicwangciso sokuhlola izimbiwa, i-China Geological Survey yeSebe leMithombo yeNdalo, ngokubambisana noRhulumente wabantu bePhondo laseHubei, yenze uphando olunzulu lwetekhnoloji yokusetyenziswa kunye nophuhliso lwe-Miaoya ultra large niobium rare deposit kwindawo yaseZhushan Zhuxi kumntla-ntshona wePhondo laseHubei. Itekhnoloji ephambili yokusetyenziswa ngokufanelekileyo kwezixhobo ze-niobium yoyisiwe, kwaye iitoni ezingama-929000 zezixhobo ze-niobium ziya kusebenza ukuze kufezekiswe ukusetyenziswa ngokoqoqosho kwe-Miaoya ultra large niobium rare deposit.
Uphuhliso kunye nokukhuthazwa kobuchwepheshe obuphambili bokusetyenziswa ngokupheleleyo kwezixhobo ze-niobium kumntla-ntshona weHubei kuya kubonelela ngendlela yezobuchwepheshe enokwenzeka ngokwezoqoqosho kwizixhobo ze-niobium zaseTshayina ezikumgangatho ophantsi nezinzima ukuzisebenzisa. Oku kubaluleke kakhulu kwi-China yokuzimela kwizixhobo ze-niobium kunye nokuphuculwa kwamandla ayo okhuseleko.
I-Niobium ineempawu zokuxhathisa ukugqwala kunye nokumelana nobushushu obuphezulu, kwaye sisinyithi esibalulekileyo esiyimfuneko kwimimandla yeenqwelo-moya, ukhuselo lwesizwe, ishishini lomkhosi, kunye namandla enyukliya. Sisixhobo esibalulekileyo sobuchule. I-China ifumene iitoni ezizigidi ezi-4.7 zezixhobo, ezibekwe kwindawo yesibini kwihlabathi, zigxile kwiindawo ezifana neBaiyun Obo e-Inner Mongolia, iLiangzhu eHubei, iYichun eJiangxi, iBaicheng eXinjiang, kunye neHuayangchuan eShaanxi. Xa kuthelekiswa namazwe angaphandle, izixhobo ze-niobium e-China ngokubanzi zineempawu ze-ore ezintsonkothileyo, amanqanaba aphantsi, kwaye kunzima ukuzisebenzisa.
Imbali yokuhlola iMiaoya niobium rare earth mine ingaqala emva kwiminyaka yoo-1960, kodwa ngenxa yemida yezobuchwepheshe, bekusoloko kunzima ukufezekisa uphuhliso nokusetyenziswa kwezixhobo. Ngokusebenzisa ngokupheleleyo iimpumelelo zobuchwepheshe, abaphandi bejoloji baseTshayina baye baphuhlisa ubuchwepheshe bokwahlulwahlulwa komhlaba onqabileyo we-niobium ngobuchule, befikelela kwimpumelelo ebalulekileyo kwiiteknoloji eziphambili zokusetyenziswa ngokufanelekileyo kwezixhobo ze-niobium. Udidi lwe-niobium concentrate lunyukile ukusuka kwi-5% ukuya kwi-8% kwiinkqubo zemveli ukuya kwi-17%, kwaye izinga lokubuyiselwa linyukile ukusuka kwi-20% ukuya kwi-50%. Kwangaxeshanye, ukusetyenziswa ngokupheleleyo kwezixhobo ezinqabileyo ezinxulumene noko, isinyithi, isalfure kunye nezinye izixhobo kuye kwafikelelwa, kuqinisekiswa ngokufanelekileyo ukhuseleko lobonelelo lwezixhobo ze-niobium eTshayina.
