Beryllium cov peev txheej hauv Tebchaws Meskas: Raws li tsab ntawv tshaj tawm los ntawm Tebchaws Meskas Geological Survey (USGS) thaum ntxov li 2015, lub ntiaj teb pov thawj beryllium cov peev txheej thaum lub sijhawm ntawd tau tshaj 80,000 tons, thiab 65% ntawm cov khoom siv beryllium yog non-granite crystalline. pob zeb faib hauv Tebchaws Meskas..Ntawm lawv, thaj chaw ntawm Gold Hill thiab Spor Roob hauv Utah, Tebchaws Asmeskas, thiab Seward Peninsula nyob rau sab hnub poob Alaska yog thaj chaw uas cov peev txheej beryllium muaj nyob hauv Tebchaws Meskas.Nyob rau hauv lub xyoo pua 21st, lub ntiaj teb beryllium ntau lawm tau nce ntau.Raws li cov ntaub ntawv tso tawm los ntawm US Geological Survey hauv 2015, lub ntiaj teb beryllium mine ntau lawm yog 270 tons, thiab Tebchaws Meskas suav txog 89% (240 tons).Tuam Tshoj yog tus thib ob loj tshaj plaws tsim nyob rau lub sij hawm ntawd, tab sis nws cov zis tseem tsis tau piv rau Tebchaws Meskas.
Tuam Tshoj cov peev txheej beryllium: Lub ntiaj teb loj tshaj plaws beryllium mine tau pom nyob rau hauv Xinjiang, kuv lub teb chaws.Yav dhau los, kev faib cov khoom siv beryllium hauv Suav teb feem ntau yog nyob rau hauv plaub lub xeev Xinjiang, Sichuan, Yunnan thiab Inner Mongolia.Cov pov thawj pov thawj ntawm beryllium feem ntau cuam tshuam nrog cov zaub mov, feem ntau cuam tshuam nrog lithium, tantalum-niobium ores (suav txog 48%), thiab thib ob cuam tshuam nrog cov ntxhia hauv ntiaj teb tsawg.(27%) los yog txuam nrog tungsten (20%).Tsis tas li ntawd, tseem muaj qee qhov me me cuam tshuam nrog molybdenum, tin, txhuas thiab zinc thiab cov zaub mov tsis yog hlau.Txawm hais tias muaj ntau cov pob zeb hauv pob zeb ntawm beryllium, lawv muaj me me hauv cov nplai thiab suav txog tsawg dua 1% ntawm tag nrho cov reserves.
Pit No. 3, Keketuohai, Xinjiang: Lub ntsiab hom ntawm beryllium deposits nyob rau hauv kuv lub teb chaws yog granite pegmatite hom, hydrothermal vein hom thiab granite (xws li alkaline granite) hom.Granite pegmatite hom yog hom tseem ceeb tshaj plaws ntawm beryllium ore, suav txog li ib nrab ntawm tag nrho cov peev hauv tsev.Nws yog tsim nyob rau hauv Xinjiang, Sichuan, Yunnan thiab lwm qhov chaw.Cov deposits no feem ntau yog muab faib rau hauv trough fold siv, thiab lub hnub nyoog metallogenic nyob nruab nrab ntawm 180 thiab 391Ma.Granite pegmatite deposits feem ntau tshwm raws li qhov chaw ntom ntom uas ob peb pegmatite dikes sib sau ua ke.Piv txwv li, hauv thaj tsam Altay pegmatite, Xinjiang, muaj ntau tshaj 100,000 pegmatite dikes paub, sib sau ua ke hauv ntau dua 39 qhov chaw ntom ntom.Pegmatite veins tshwm nyob rau hauv cov pab pawg nyob rau hauv lub mining cheeb tsam, lub ore lub cev yog complex nyob rau hauv cov duab, thiab beryllium bearing mineral yog beryl.Vim hais tias cov pob zeb hauv av yog ntxhib, yooj yim rau kuv thiab xaiv, thiab cov ore deposits tau dav faib, nws yog qhov tseem ceeb tshaj plaws kev lag luam mining hom beryllium ore hauv kuv lub teb chaws.
Ntawm cov beryllium ore hom, granite pegmatite-hom beryllium ore muaj peev xwm tshaj plaws rau kev cia siab hauv kuv lub tebchaws.Hauv ob qhov tsis tshua muaj hlau metallogenic siv ntawm Altay thiab West Kunlun hauv Xinjiang, kaum tawm txhiab square kilometers ntawm metallogenic thaj chaw yav tom ntej tau muab faib.Muaj ze li ntawm 100,000 crystal veins.
Piv txwv li, los ntawm kev xav ntawm kev txhim kho thiab kev siv, kuv lub teb chaws cov khoom siv beryllium ore muaj peb yam zoo li nram no:
1. Kuv lub teb chaws cov khoom siv beryllium ore yog cov concentrated, uas yog qhov tsim nyog rau kev txhim kho thiab kev siv.kuv lub teb chaws beryllium industrial reserves yog concentrated nyob rau hauv Keketuohai Mine nyob rau hauv Xinjiang, accounting rau 80% ntawm lub teb chaws muaj reserves;
2. Cov ore qib qis, thiab muaj ob peb cov nplua nuj nyob hauv cov pov thawj pov tseg.BeO qib ntawm pegmatite beryllium ore mined txawv teb chaws yog siab dua 0.1%, thaum nyob rau hauv kuv lub teb chaws yog qis dua 0.1%, uas muaj kev cuam tshuam ncaj qha rau cov txiaj ntsig ntawm cov txiaj ntsig ntawm domestic beryllium concentrate.
3. Kev lag luam reserves ntawm beryllium account rau ib feem me me ntawm cov reserves, thiab cov reserves yuav tsum tau upgraded.Hauv xyoo 2015, kuv lub teb chaws cov peev txheej tau teev tseg (BeO) yog 574,000 tons, uas cov peev txheej hauv paus yog 39,000 tons, nyob rau qib thib ob hauv ntiaj teb.
Beryllium cov peev txheej nyob rau hauv Russia: Russia lub Sverdlovsk cheeb tsam tau pib ib tug systematic geological thiab economic kev ntsuam xyuas ntawm lub xwb emerald beryllium mine "Malyinsky Mine"."Maliyink Mine" yog nyob rau hauv kev txiav txim ntawm РТ-Капитал Co., Ltd., ib tug subsidiary ntawm Lavxias teb sab xeev-muaj enterprise "Rostec".Kev ntsuam xyuas cov dej num rau cov mine yog teem kom tiav los ntawm Lub Peb Hlis 2021.
Maliinsky mine, nyob ze ntawm lub zos Mareshova, belongs rau Russia lub teb chaws cov kev pab cuam.Qhov kev ntsuam xyuas zaum kawg tau ua tiav tom qab kev tshawb nrhiav geological hauv xyoo 1992. Cov ntaub ntawv ntawm lub mine no tau hloov kho tam sim no.Txoj haujlwm tshiab tau nthuav tawm cov ntaub ntawv dav dav ntawm kev khaws cia ntawm beryl, beryllium oxide thiab lwm yam khoom siv.
Maliinsky Mine yog ib qho ntawm plaub qhov loj tshaj plaws beryl beryllium mines hauv ntiaj teb thiab tsuas yog beryl beryllium mine hauv Russia.Beryl ua los ntawm cov mine no yog qhov tshwj xeeb thiab tsis tshua muaj nyob hauv lub ntiaj teb thiab feem ntau suav nrog hauv lub tebchaws lub pov haum thiab cov khoom siv hlau muaj txiaj ntsig.Txhua xyoo, Maliinsky mine ua txog 94,000 tons ntawm ore, tsim 150 kilograms ntawm emeralds, 2.5 kilograms ntawm alexandrite (alexandrite), thiab tsib tons ntawm ntau tshaj beryl.
Tebchaws Asmeskas tau siv los ua lub ntiaj teb cov khoom lag luam tseem ceeb, tab sis qhov xwm txheej tau hloov pauv.Raws li kev txheeb cais ntawm Chatham House, thaum ntxov li 2016, lub saum toj tsib exporters ntawm beryllium khoom nyob rau hauv lub ntiaj teb no yog: Madagascar (208 tons), Switzerland (197 tons), Ethiopia (84 tons), Slovenia (69 tons), Lub teb chaws Yelemees (51 tons);Cov neeg xa khoom thoob ntiaj teb yog Tuam Tshoj (293 tons), Australia (197 tons), Belgium (66 tons), Spain (47 tons) thiab Malaysia (10 tons).
Cov chaw muag khoom tseem ceeb ntawm cov ntaub ntawv beryllium hauv Tebchaws Meskas yog: Kazakhstan, Nyiv, Brazil, United Kingdom thiab Fabkis.Los ntawm 2013 txog 2016, Kazakhstan suav txog 47% ntawm Tebchaws Meskas cov khoom xa tuaj, Nyiv suav txog 14%, Brazil suav txog 8%, thiab Tebchaws Askiv suav txog 8%, thiab lwm lub tebchaws suav txog 23%.Lub ntsiab exporters ntawm US beryllium cov khoom yog Malaysia, Tuam Tshoj thiab Nyiv.Raws li Materion, beryllium tooj liab alloys suav txog li 85 feem pua ntawm US beryllium cov khoom xa tawm.
