NiobiumBaotou kuv
Ib qho ntxhia tshiab muaj npe tom qab nws cov keeb kwm Suav tau pom
Tsis ntev los no, Suav cov kws tshawb fawb tau tshawb pom cov ntxhia tshiab -niobiumBaotou ore, uas yog cov ntxhia tshiab nplua nuj nyob rau hauv cov khoom siv hlau. Cov khoom nplua nuj niobium muaj cov ntawv thov tseem ceeb hauv thaj chaw xws li Tuam Tshoj txoj kev lag luam nuclear.
Niobium Baotou ore yog cov ntxhia silicate nplua nuj nyob hauvbarium, niobium, titanium, hlau, thiab chlorine. Nws tau pom nyob rau hauv Baiyunebo deposit hauv Baotou City, Inner Mongolia. Niobium Baotou ore yog xim av mus rau xim dub, nyob rau hauv cov duab ntawm kab los yog daim hlau, nrog particle loj li ntawm 20-80 microns.
Fan Guang, Senior Engineer ntawm CNNC Geological Technology: Hauv xyoo 2012, thaum lub sijhawm tshawb nrhiav geochemical, peb tau coj ntau yam qauv thiab pom cov ntxhia nplua nuj nyob hauvniobium. Nws cov tshuaj muaj pes tsawg leeg yog txawv ntawm Baotou ore nrhiav pom nyob rau hauv thawj qhov chaw mining. Yog li ntawd, peb ntseeg tias qhov no yog cov ntxhia tshiab thiab xav tau kev tshawb fawb ntxiv.
Nws tau tshaj tawm tias Baiyunebo deposit qhov twgNiobiumBaotou ore tau tshawb pom muaj ntau yam minerals, nrog ntau tshaj 170 hom nrhiav tau tam sim no.NiobiumBaotou ore yog 17th tshiab ntxhia pom hauv qhov tso nyiaj no.
Ge Xiangkun, Senior Engineer ntawm CNNC Geological Technology: Los ntawm nws cov tshuaj muaj pes tsawg leeg, nws yog Baotou ore nrog cov ntsiab lus siab ntawmniobium, uas yuav tsum tau siv los rho tawmniobiumkeeb.Niobiumyog lub tswv yim thiab cov hlau tseem ceeb hauv peb lub teb chaws, uas tuaj yeem siv tau rau ntau qhov xwm txheej thiab muaj cov ntawv thov tseem ceeb hauv kev lag luam nuclear. Tsis tas li ntawd, nws tseem tuaj yeem siv los tsim cov khoom siv superconducting, kub-kub alloys, thiab lwm yam.
Kev tuaj xyuas los ntawm cov neeg sau xov xwm:
Yuav ua li cas nrhiav tau cov zaub mov tshiab hauv plaub kauj ruam tseem ceeb?
Lub discovery ntawm lubNiobiumBaotou mine tau koom tes rau thoob ntiaj teb mineralogy. Txog tam sim no, cov kws tshawb fawb los ntawm Tuam Tshoj Nuclear Geological Technology tau tshawb pom tag nrho 11 cov zaub mov tshiab. Cov pob zeb tshiab tau tshawb pom li cas? Cov cuab yeej siv txuj ci dab tsi ntxiv? Ua raws li tus neeg sau xov xwm mus saib.
Raws li tus neeg sau xov xwm, nrhiav pom cov pob zeb tshiab yuav tsum muaj tag nrho ntawm 4 kauj ruam. Thawj kauj ruam yog kev tshuaj xyuas tshuaj muaj pes tsawg leeg, thiab cov khoom siv hluav taws xob sojntsuam tuaj yeem kuaj xyuas cov tshuaj muaj pes tsawg leeg ntawm cov qauv.
Deng Liumin, tus kws tshaj lij ntawm CNNC Geological Science thiab Technology, tau hais tias nws siv lub zog hluav taws xob tsom hluav taws xob los tawm tsam qhov chaw ntawm tus qauv thiab ntsuas cov ntsiab lus ntawm ntau lub ntsiab lus. Los ntawm kev txiav txim siab cov ntsiab lus ntawm lub caij no, nws cov tshuaj formula tuaj yeem txiav txim siab seb nws puas yog tshiab. Kev txiav txim siab cov tshuaj muaj pes tsawg leeg kuj yog ib kauj ruam tseem ceeb hauv kev kawm txog cov zaub mov tshiab.
Los ntawm kev ntsuam xyuas electron, cov kws tshawb fawb tau txais cov tshuaj muaj pes tsawg leeg ntawm cov ntxhia tshiab, tab sis cov tshuaj muaj pes tsawg leeg tsis txaus. Txhawm rau txiav txim siab seb nws puas yog cov ntxhia tshiab, nws yog qhov tsim nyog los tshuaj xyuas cov qauv siv lead ua ntawm cov pob zeb hauv av, uas yuav tsum tau nkag mus rau theem ob - cov qauv npaj.
Wang Tao, tus kws tshaj lij ntawm CNNC Geological Technology, tau hais tias cov khoom nyob hauvniobiumBaotou kuv kuj me me. Peb siv lub tsom ion beam cais cov ntxhia hais
Txiav nws tawm, nws yog hais txog 20 microns × 10 microns × 7 micron hais. Vim tias peb yuav tsum txheeb xyuas nws cov qauv siv lead ua, yog li nws yog qhov tsim nyog los xyuas kom meej tias nws cov khoom xyaw yog ntshiab. Qhov no yog cov qauv peb txiav tawm, thiab peb yuav sau nws cov ntaub ntawv qhia txog kev ua pa tom ntej.
Li Ting, Senior Engineer ntawm CNNC Geological Technology: Peb cov khoom yuav muab tso rau hauv nruab nrab ntawm qhov ntsuas, ntawm tus qauv tuav. Qhov no yog lub teeb ci (X-ray), thiab qhov no yog lub receiver. Thaum lub teeb (X-ray) dhau los ntawm cov siv lead ua thiab tau txais los ntawm tus txais, nws twb nqa cov ntaub ntawv ntawm cov khoom siv lead ua. Cov qauv ntawm niobium baotou ore uas peb thaum kawg daws tau yog tetragonal siv lead ua system, uas yog kev npaj ntawm atoms nrog ib leeg.
Thaum cov tshuaj muaj pes tsawg leeg thiab cov qauv siv lead ua ntawm cov pob zeb tshiab tau txais, cov ntaub ntawv yooj yim sau rau cov pob zeb tshiab tau ua tiav. Tom ntej no, Ke
Cov kws tshawb fawb tseem yuav tsum tau ua cov kev soj ntsuam spectral thiab kuaj lub cev lub cev los txhim kho cov ntaub ntawv cuam tshuam ntawm cov ntxhia tshiab, thiab thaum kawg sau cov ntaub ntawv rau cov ntawv thov pob zeb tshiab tuaj yeem pom zoo thoob ntiaj teb tom qab dhau cov txheej txheem tshuaj xyuas.
Kev tshuaj xyuas nruj thiab paub lub npe ntawm cov zaub mov tshiab
Tau txais kev pom zoo thoob ntiaj teb tsis yog ib txoj haujlwm yooj yim. Tus neeg sau xov xwm tau kawm tias lub npe ntawm cov zaub mov tshiab yuav tsum tau tshuaj xyuas cov txheej txheem los ntawm txheej.
Tom qab tau txais cov ntaub ntawv ntxhia tshiab, cov kws tshawb fawb yuav tsum tau thov rau International Society of Mineralogy, lub koom haum loj tshaj plaws hauv ntiaj teb. Tus Thawj Tswj Hwm ntawm Cov Minerals Tshiab, Kev faib tawm, thiab Nomenclature Committee ntawm International Society of Mineralogy yuav ua qhov kev tshuaj xyuas ua ntej ntawm daim ntawv thov, txheeb xyuas qhov tsis txaus hauv kev tshawb fawb, thiab muab cov lus pom zoo.
Fan Guang, Senior Engineer ntawm CNNC Geological Technology: Cov kauj ruam no yog nruj thiab nruj heev. Tom qab tau txais kev lees paub los ntawm Thawj Tswj Hwm ntawm Pawg Neeg Minerals Tshiab, Kev faib tawm, thiab Nomenclature Committee ntawm International Mineral Society, cov tswv cuab ntawm International New Minerals Classification thiab Nomenclature Committee yuav raug tso cai pov npav. Yog tias pom zoo los ntawm ob feem peb feem coob, Thawj Tswj Hwm ntawm Cov Minerals Tshiab, Kev faib tawm, thiab Nomenclature Committee ntawm International Mineral Society yuav tshaj tawm tsab ntawv pom zoo, uas sawv cev tias peb cov minerals tau raug pom zoo. Tsis pub dhau ob xyoos, peb yuav muaj ib tsab xov xwm raug tshaj tawm.
Txog tam sim no, Tuam Tshoj tau tshawb pom ntau dua 180 cov zaub mov tshiab, suav nrog pob zeb Chang'e, Mianning uranium ore, Luan lithium mica, thiab lwm yam.
Fan Guang, Senior Engineer ntawm CNNC Geological Technology: Qhov kev tshawb pom ntawm cov zaub mov tshiab sawv cev rau qib ntawm kev tshawb fawb mineralogical hauv ib lub tebchaws. Tshawb nrhiav cov zaub mov tshiab yog ib txoj hauv kev los mus nrhiav qhov kawg, nkag siab lub ntiaj teb, thiab nkag siab qhov xwm txheej. Kuv vam tias yuav pom cov neeg Suav nyob rau theem thoob ntiaj teb mineralogy.
