Tantalum-niobium mining cov peev txheej

Tau ntev heev tom qab kev tsim ntawm Tuam Tshoj Tshiab, lub teb chaws capitalist thaiv thiab embargoed tsis tshua muaj thiab tsis tshua muaj ntiaj teb hlau minerals xws li lithium, beryllium, niobium thiab tantalum ua cov khoom siv rau peb lub teb chaws, thiab yog li lub teb chaws txiav txim siab los ua tus kheej. , raws li kev daws teeb meem hauv tsev ntawm cov khoom siv ntxhia, thiab txhim kho Tuam Tshoj txoj kev lag luam tsis tshua muaj thiab tsis tshua muaj ntiaj teb hlau. Ua pov thawj sai heev ntawm cov pob zeb loj, loj heev, xws li Xinjiang's Fuyun Kokotohai, Kerumut, Qinghe Ascarte, Fuhai Kukaragai, Fuhai Quncourt thiab lwm yam loj, nruab nrab lithium-beryllium niobium-tantalum mine, Inner Mongolia Baiyun Ebo super loj niobium -tsis tshua muaj av mines, Sichuan's Kanding Mekat loj lithium-beryllium mine, Jinchuan Kerin loj lithium mine, Qinghai ChaiDaMu Basin, ib mais ntawm ping thiab sab hnub tuaj thiab sab hnub poob ntawm lub rooj Ginel Lake, thiab lwm yam. Extra-loj ntsev pas dej lithium mine, Jiangxi Hengfeng Huangshan loj tantalum thiab niobium mine, Guangdong's Zengcheng PaiTan loj niobium-hlau ore xuab zeb mine, loj niobium-tantalum mine nyob rau hauv Boro cheeb tsam, Guangxi's HeXian Gubashan loj yttrium xim av niobium ore xuab zeb Li nruab nrab ntawm tigurnihum mine mine, Hunan XiangHuaLing beryllium mine, thiab lwm yam. Tom qab xyoo 1970, nyob rau hauv lub fifties thiab sixties, loj-scale suav pej xeem mus nrhiav minerals raws li ib tug xov tooj ntawm mines tau pom thiab soj ntsuam. Xws li Jiangxi's Yichun loj tantalum (niobium)-lithium mine, Hengfeng Geyuan tantalum-niobium tungsten-tin mine (tantalum loj), Shicheng Hailuoling nruab nrab-loj niobium-tantalum mine, Hubei's Zhushan Miaoya tshwj xeeb loj niobium, T. Cov Peak Hill loj tantalum-niobium mine, Zalut Banner Baltzhe loj niobium thiab tsawg lub ntiaj teb mines, loj niobium thiab niobium ore, Fujian, Nanping Xikeng loj niobium thiab niobium mine, Guangdong, Guangdong, Guangning, Hengshan medium-qhov loj me niobium niobium thiab , thiab Guangxi Gongcheng ShuiXiMiao tantalum thiab niobium mine (tantalum loj), Jinzhuyuan tantalum-niobium mine (tantalum loj) thiab hais txog. Tuam Tshoj tus tsawg hlau mineral reserves nyob rau hauv lub ntiaj teb no nyob rau hauv lub forefront.

Tuam Tshoj yog lub teb chaws nplua nuj tshaj plaws hauv ntiaj teb hauv niobium, tantalum, lithium, beryllium thiab lwm yam khoom siv hlau tsis tshua muaj hlau. Tuam Tshoj lub lithium, beryllium, niobium, tantalum ore reserves nyob rau hauv lub ntiaj teb no ranked thawj ob. Raws li US Bureau of Mines (1981-1994) kwv yees, lub ntiaj teb lithium, beryllium, niobium, tantalum mineral reserves raws li: lithium (hlau npaum li cas) 8.4 lab tons, beryllium (hlau npaum li cas) 726, {{4} } tons, niobium (hlau npaum li cas) 4.2 lab tons, tantalum (hlau npaum li cas) 35, 000 tons. Tuam Tshoj plaub lub ntxhia, raws li Ministry of Geology thiab Mineral Resources tau teeb tsa los ntawm "40th hnub tseem ceeb ntawm kev tsim ntawm Tuam Tshoj txoj kev ua tiav hauv geology thiab mining exhibition" txheeb cais (Geological Publishing House, 1992): Tuam Tshoj tus tantalum, lithium ore suav rau lub ntiaj teb thawj zaug. , niobium, beryllium ore yog suav tias yog qhov chaw thib ob.
Tantalum ore yog faib nyob rau hauv 13 lub xeev (cov cheeb tsam) ntawm 92 mining cheeb tsam, tag nrho cov reserves reserves Ta2O5 84,000 tons, qeb duas nyob rau hauv lub ntiaj teb no; los ntawm kev faib khoom hauv cheeb tsam, Jiangxi tantalum ore yog cov nplua nuj tshaj plaws, Inner Mongolia, Guangdong, ua raws li peb lub xeev, suav txog 72.5% ntawm lub teb chaws tantalum reserves.
Niobium pov thawj reserves ntawm niobium-raws li mines yog 99, niobium industrial reserves ntawm 6.6 lab tons, qeb thib ob hauv ntiaj teb; thiab lwm tus tau hais tias, raws li kev tshawb nrhiav tshiab, Tuam Tshoj lub niobium reserves suav txog 91% ntawm lub ntiaj teb, tej zaum yuav tau dhia mus rau thawj qhov chaw.
