Kusukela ekuqalisweni komjikelezo omusha wentuthuko esu lokuhlola izimbiwa, i-China Geological Survey yoMnyango Wezinsiza Zemvelo, ngokubambisana noHulumeni Wabantu Wesifundazwe saseHubei, yenze ucwaningo olunzulu lobuchwepheshe bokusetshenziswa kanye nokuthuthukiswa kwe-Miaoya ultra large niobium rare earth deposit endaweni yaseZhushan Zhuxi enyakatho-ntshonalanga yesifundazwe saseHubei. Ubuchwepheshe obuyinhloko bokusetshenziswa kahle kwezinsiza ze-niobium sebunqotshiwe, futhi kuzosetshenziswa amathani angu-929000 ezinsiza ze-niobium ukuze kufezwe ukusetshenziswa ngokomnotho kwe-Miaoya ultra large niobium rare deposit.
Intuthuko kanye nokukhuthazwa kobuchwepheshe obuyinhloko bokusetshenziswa okuphelele kwezinsiza ze-niobium enyakatho-ntshonalanga yeHubei kuzohlinzeka ngendlela yezobuchwepheshe ephumelelayo ngokwezomnotho yezinsiza ze-niobium zaseShayina ezisezingeni eliphansi futhi ezinzima ukuzisebenzisa. Lokhu kubaluleke kakhulu ekwanelisekeni kweShayina ngezinsiza ze-niobium kanye nokuthuthukiswa kwamakhono ayo okuphepha.
I-Niobium inezici zokumelana nokugqwala kanye nokumelana nokushisa okuphezulu, futhi iyinsimbi ebalulekile ebaluleke kakhulu emikhakheni yezindiza, ukuzivikela kwezwe, imboni yezempi, kanye namandla enuzi. Ingumthombo obalulekile wamasu. I-China ithole amathani ayizigidi ezingu-4.7 ezinsiza, ebekwe endaweni yesibili emhlabeni, igxile ezindaweni ezifana ne-Baiyun Obo e-Inner Mongolia, i-Liangzhu e-Hubei, i-Yichun e-Jiangxi, i-Baicheng e-Xinjiang, kanye ne-Huayangchuan e-Shaanxi. Uma kuqhathaniswa namazwe angaphandle, izinsiza ze-niobium e-China ngokuvamile zinezakhiwo ze-ore eziyinkimbinkimbi, amazinga aphansi, futhi kunzima ukuzisebenzisa.
Umlando wokuhlola imayini yomhlaba engavamile ye-Miaoya niobium ungalandelelwa emuva ngawo-1960, kodwa ngenxa yemikhawulo yezobuchwepheshe, bekulokhu kunzima ukufeza intuthuko nokusetshenziswa kwezinsiza. Ngokusebenzisa ngokuphelele intuthuko yezobuchwepheshe, abacwaningi bejiyoloji baseShayina bathuthukise ubuchwepheshe bokuhlukanisa umhlaba ongavamile we-niobium ngobuhlakani, bafinyelela intuthuko ebalulekile kubuchwepheshe obuyinhloko bokusetshenziswa kahle kwezinsiza ze-niobium. Izinga lokugxilisa i-niobium likhuphuke kusuka ku-5% kuya ku-8% ezinqubweni zendabuko laya ku-17%, kanti izinga lokutakula likhuphuke kusuka ku-20% kuya ku-50%. Ngesikhathi esifanayo, ukusetshenziswa okuphelele kwezinsiza ezingavamile ezihlobene, insimbi, isibabule kanye nezinye kufeziwe, okuqinisekisa ngempumelelo ukuphepha kokutholakala kwezinsiza ze-niobium eShayina.
