Kuyambira pomwe njira zatsopano zofufuzira za mchere zinayambika, bungwe la China Geological Survey la Unduna wa Zachilengedwe, mogwirizana ndi Boma la Anthu ku Hubei Province, lachita kafukufuku waukadaulo wogwiritsa ntchito bwino komanso chitukuko cha malo osungiramo zinthu zakale a Miaoya m'dera la Zhushan Zhuxi kumpoto chakumadzulo kwa Hubei Province. Ukadaulo wofunikira kwambiri wogwiritsira ntchito bwino zinthu za niobium wagonjetsedwa, ndipo matani 929000 a zinthu za niobium adzagwiritsidwa ntchito kuti malo osungiramo zinthu zakale a Miaoya agwiritsidwe ntchito pazachuma.
Kupita patsogolo ndi kukwezedwa kwa ukadaulo wofunikira kwambiri kuti ugwiritsidwe ntchito bwino kwa zinthu za niobium kumpoto chakumadzulo kwa Hubei kudzapereka njira yaukadaulo yothandiza pazachuma kwa zinthu za niobium zotsika mtengo komanso zovuta kugwiritsa ntchito ku China. Izi ndizofunikira kwambiri pakudzidalira kwa China pa zinthu za niobium komanso kukonza chitetezo chake.
Niobium ili ndi makhalidwe ofanana ndi kukana dzimbiri komanso kukana kutentha kwambiri, ndipo ndi chitsulo chofunikira kwambiri m'magawo a ndege, chitetezo cha dziko, makampani ankhondo, ndi mphamvu ya nyukiliya. Ndi chuma chofunikira kwambiri. China yapeza matani 4.7 miliyoni a zinthu, chomwe chili chachiwiri padziko lonse lapansi, chomwe chili m'malo monga Baiyun Obo ku Inner Mongolia, Liangzhu ku Hubei, Yichun ku Jiangxi, Baicheng ku Xinjiang, ndi Huayangchuan ku Shaanxi. Poyerekeza ndi mayiko akunja, zinthu za niobium ku China nthawi zambiri zimakhala ndi zinthu zovuta za miyala, zochepa, ndipo zimakhala zovuta kugwiritsa ntchito.
Mbiri yofufuza za mgodi wa Miaoya niobium rare earth imayamba m'zaka za m'ma 1960, koma chifukwa cha zovuta zaukadaulo, nthawi zonse zakhala zovuta kupeza chitukuko ndi kugwiritsa ntchito zinthu. Pogwiritsa ntchito bwino ukadaulo, ofufuza za geology aku China apanga ukadaulo wolekanitsa nthaka rare earth wa niobium mwaluso, zomwe zapangitsa kuti pakhale kupita patsogolo kwakukulu muukadaulo wofunikira kuti zinthu za niobium zigwiritsidwe ntchito bwino. Mlingo wa niobium concentrate wakwera kuchoka pa 5% mpaka 8% m'njira zachikhalidwe kufika pa 17%, ndipo kuchuluka kwa kuchira kwakwera kuchoka pa 20% mpaka 50%. Nthawi yomweyo, kugwiritsa ntchito bwino zinthu za rare earth, chitsulo, sulfure ndi zina kwachitika, zomwe zatsimikizira kuti chuma cha niobium chili bwino ku China.
