Beryllium yog lub teeb hlau tsis tshua muaj, thiab cov khoom tsis muaj hlau uas tau teev tseg hauv pawg no suav nrog lithium (Li), rubidium (Rb), thiab cesium (Cs).Lub reserves ntawm beryllium nyob rau hauv lub ntiaj teb no tsuas yog 390kt, qhov siab tshaj plaws txhua xyoo tso zis tau mus txog 1400t, thiab lub xyoo qis tshaj yog tsuas yog hais txog 200t.Tuam Tshoj yog ib lub teb chaws uas muaj peev xwm loj beryllium, thiab nws cov zis tsis tau tshaj 20t/a, thiab beryllium ore tau pom nyob rau hauv 16 lub xeev (autonomous regions).Ntau tshaj 60 hom beryllium minerals thiab beryllium-muaj cov zaub mov tau pom, thiab muaj txog 40 hom.Xianghashi thiab Shunjiashi hauv Hunan yog ib qho ntawm thawj cov nyiaj tso nyiaj beryllium pom hauv Suav teb.Beryl [Be3Al2 (Si6O18)] yog cov ntxhia tseem ceeb tshaj plaws rau kev rho tawm beryllium.Nws cov ntsiab lus yog 9.26% ~ 14.4%.Zoo beryl yog tiag tiag emerald, yog li nws tuaj yeem hais tias beryllium los ntawm emerald.Los ntawm txoj kev, ntawm no yog ib zaj dab neeg hais txog yuav ua li cas Tuam Tshoj nrhiav tau beryllium, lithium, tantalum-niobium ore.

Nyob rau hauv nruab nrab-1960s, txhawm rau tsim "ob lub foob pob thiab ib lub satellite", Tuam Tshoj xav tau cov hlau tsis tshua muaj xws li tantalum, niobium, zirconium, hafnium, beryllium, thiab lithium., "87" yog hais txog tus lej xov tooj ntawm txoj haujlwm hauv lub tebchaws tseem ceeb yog 87, yog li pab pawg tshawb nrhiav tsim los ntawm geologists, cov tub rog thiab cov kws tshaj lij thiab cov kws tshaj lij tau tsim los mus rau sab qaum teb sab hnub tuaj ntawm Junggar Basin hauv Xinjiang, Irtysh Hauv. cov suab puam thiab thaj av tsis muaj av nyob rau sab qab teb ntawm tus dej, tom qab kev siv zog ua haujlwm nyuaj, thaj chaw Coketuohai mining thaum kawg tau pom.Cov neeg ua haujlwm "6687" tau tshawb pom peb qhov tseem ceeb tsis tshua muaj hlau mines, 01, 02 thiab 03, hauv Keketuohai No. 3 Mine.Qhov tseeb, ore 01 yog beryl siv los rho tawm beryllium, ore 02 yog spodumene, thiab ore 03 yog tantalum-niobite.Cov extracted beryllium, lithium, tantalum, thiab niobium yog tshwj xeeb tshaj yog muaj feem xyuam rau Tuam Tshoj tus "ob lub foob pob thiab ib lub hnub qub".lub luag haujlwm tseem ceeb.Lub Cocoto Hiav Txwv Mine kuj tau txais lub koob npe nrov ntawm "qhov chaw dawb huv ntawm ntiaj teb geology".

Muaj ntau tshaj 140 hom beryllium minerals uas tuaj yeem khawb hauv lub ntiaj teb, thiab muaj 86 hom beryllium minerals hauv Cocotohai 03 mine.Lub beryllium siv nyob rau hauv gyroscopes ntawm ballistic missiles, thawj atomic foob pob, thiab thawj hydrogen foob pob nyob rau hauv thaum ntxov hnub ntawm cov neeg koom pheej ntawm Tuam Tshoj tag nrho cov los ntawm 6687-01 mineral nyob rau hauv lub hiav txwv Cocoto, thiab cov lithium siv nyob rau hauv thawj. atomic foob pob los ntawm 6687-02 mine, lub cesium siv nyob rau hauv New Tuam Tshoj tus thawj lub ntiaj teb dag satellite kuj los ntawm lub mine.

Kev rho tawm ntawm beryllium yog thawj zaug rho tawm beryllium oxide los ntawm beryl, thiab tom qab ntawd tsim beryllium los ntawm beryllium oxide.Kev rho tawm ntawm beryllium oxide suav nrog txoj kev sulfate thiab fluoride txoj kev.Nws yog qhov nyuaj heev los txo qis beryllium oxide rau beryllium.Hauv kev tsim khoom, beryllium oxide yog thawj zaug hloov mus rau halide, thiab tom qab ntawd txo mus rau beryllium.Muaj ob txoj kev: beryllium fluoride txo txoj kev thiab beryllium chloride molten ntsev electrolysis txoj kev.Cov hlaws beryllium tau txais los ntawm kev txo qis yog lub tshuab nqus tsev smelted kom tshem tawm cov tsis muaj magnesium, beryllium fluoride, magnesium fluoride thiab lwm yam impurities, thiab ces muab pov rau hauv ingots;electrolytic nqus tsev vacuum smelting yog siv los cam khwb cia rau hauv ingots.Hom beryllium no feem ntau hu ua kev lag luam ntshiab beryllium.

Txhawm rau npaj siab dua-purity beryllium, lub crude beryllium tuaj yeem ua tiav los ntawm lub tshuab nqus tsev distillation, molten ntsev electrorefining lossis cheeb tsam smelting.
