Txij li thaum siv txoj kev tshawb nrhiav tshiab, Tuam Tshoj Geological Survey ntawm Ministry of Natural Resources, ua ke nrog Tsoomfwv Neeg ntawm Hubei Xeev, tau ua kev tshawb fawb txog kev siv tshuab thiab kev txhim kho ntawm Miaoya ultra large niobium rare earth deposit hauv thaj tsam Zhushan Zhuxi ntawm sab qaum teb sab hnub poob Hubei Xeev. Cov thev naus laus zis tseem ceeb rau kev siv cov peev txheej niobium tau raug kov yeej, thiab 929000 tons ntawm cov peev txheej niobium yuav raug qhib kom ua tiav kev siv nyiaj txiag ntawm Miaoya ultra large niobium rare earth deposit.
Kev tshawb pom thiab kev txhawb nqa cov thev naus laus zis tseem ceeb rau kev siv cov peev txheej niobium thoob plaws hauv sab qaum teb sab hnub poob Hubei yuav muab txoj hauv kev thev naus laus zis uas ua tau zoo rau Tuam Tshoj cov peev txheej niobium qib qis thiab nyuaj siv. Qhov no yog qhov tseem ceeb heev rau Tuam Tshoj txoj kev txaus siab rau tus kheej hauv cov peev txheej niobium thiab kev txhim kho nws lub peev xwm kev ruaj ntseg.
Niobium muaj cov yam ntxwv ntawm kev tiv thaiv corrosion thiab kub siab, thiab yog ib qho hlau tseem ceeb hauv kev lag luam aerospace, kev tiv thaiv lub teb chaws, kev lag luam tub rog, thiab lub zog nuclear. Nws yog ib qho khoom siv tseem ceeb. Tuam Tshoj tau tshawb pom 4.7 lab tons ntawm cov khoom siv, qeb thib ob hauv ntiaj teb, tsom mus rau thaj chaw xws li Baiyun Obo hauv Inner Mongolia, Liangzhu hauv Hubei, Yichun hauv Jiangxi, Baicheng hauv Xinjiang, thiab Huayangchuan hauv Shaanxi. Piv nrog rau lwm lub teb chaws, cov khoom siv niobium hauv Tuam Tshoj feem ntau muaj cov khoom siv ore nyuaj, qib qis, thiab nyuaj rau siv.
Keeb kwm tshawb nrhiav ntawm Miaoya niobium rare earth mine tuaj yeem taug qab mus rau xyoo 1960, tab sis vim muaj kev txwv ntawm thev naus laus zis, nws yeej ib txwm nyuaj rau kev tsim kho thiab siv cov peev txheej. Los ntawm kev siv cov thev naus laus zis dav dav, cov kws tshawb fawb txog geological Suav tau tsim cov thev naus laus zis sib cais niobium rare earth, ua tiav cov kev tshawb fawb tseem ceeb hauv cov thev naus laus zis tseem ceeb rau kev siv cov peev txheej niobium kom zoo. Qib ntawm niobium concentrate tau nce ntawm 5% mus rau 8% hauv cov txheej txheem ib txwm mus rau 17%, thiab tus nqi rov qab tau nce ntawm 20% mus rau 50%. Tib lub sijhawm, kev siv tag nrho ntawm cov av tsis tshua muaj, hlau, sulfur thiab lwm yam peev txheej tau ua tiav, ua kom ntseeg tau tias muaj kev ruaj ntseg ntawm kev muab cov peev txheej niobium hauv Suav teb.
