Industrially, ntuj graphite tau muab faib ua crystalline graphite thiab cryptocrystalline graphite raws li daim ntawv siv lead ua. Lub crystalline graphite yog crystallized zoo dua, thiab cov siv lead ua phaj txoj kab uas hla yog> 1 μm, uas feem ntau yog tsim los ntawm ib tug siv lead ua los yog flaky siv lead ua. Crystalline graphite yog ib qho ntawm 24 lub tswv yim minerals hauv lub tebchaws. Kev tshawb nrhiav thiab kev loj hlob ntawm graphite yog teev nyob rau hauv National Mineral Resources Planning (2016-2020) thawj zaug. Qhov tseem ceeb ntawm crystalline graphite yog coj los ntawm cov ntsiab lus xws li lub zog tshiab tsheb thiab graphene. Ib qho tseem ceeb nce.
Raws li US Geological Survey (USGS), txij li thaum kawg ntawm 2017, lub ntiaj teb cov graphite reserves yog hais txog 270 lab tons, feem ntau faib nyob rau hauv Qaib Cov Txwv, Tuam Tshoj thiab Brazil, uas Tuam Tshoj yog dominated los ntawm crystalline graphite thiab Qaib ntxhw yog cryptocrystalline graphite. Cryptocrystalline graphite muaj tus nqi qis thiab kev txhim kho thiab kev siv cov kev cia siab, yog li crystalline graphite txiav txim siab lub ntiaj teb graphite qauv.
Raws li Suav Academy ntawm Kev Tshawb Fawb, Tuam Tshoj tus crystalline graphite suav nrog ntau dua 70% ntawm lub ntiaj teb tag nrho. Ntawm lawv, Heilongjiang Xeev cov khoom siv crystalline graphite tuaj yeem suav txog 60% ntawm Tuam Tshoj thiab ntau dua 40% ntawm lub ntiaj teb, uas ua lub luag haujlwm txiav txim siab. Lub ntiaj teb cov neeg tsim khoom loj ntawm crystalline graphite yog Tuam Tshoj, ua raws li Is Nrias teb thiab Brazil.

txheej txheem txheej txheem
Tuam Tshoj cov graphite deposits muaj cov qib kev lag luam zoo, uas zoo rau kev tsuas, thiab qib crystalline graphite tsis tsawg dua 3%. Hauv 10 xyoo dhau los, Tuam Tshoj cov khoom tsim tawm txhua xyoo ntawm graphite yog nyob nruab nrab ntawm 60,000 thiab 800,000 tons, ntawm cov crystalline graphite ntau lawm suav txog 80%.
Muaj ntau tshaj li ib txhiab graphite ua lag luam nyob rau hauv Suav teb, thiab cov khoom yog graphite mineral khoom xws li nruab nrab thiab siab carbon graphite, siab purity graphite thiab nplua hmoov graphite, raws li zoo raws li nthuav graphite thiab carbon cov ntaub ntawv. Qhov xwm txheej ntawm kev lag luam yog lub xeev-khiav, uas yog feem ntau faib hauv Shandong, Inner Mongolia, Hubei, Heilongjiang, Zhejiang thiab lwm qhov chaw. Lub xeev cov tuam txhab graphite mining muaj lub hauv paus ruaj khov thiab muaj txiaj ntsig zoo hauv kev siv tshuab thiab cov peev txheej.
Graphite yog dav siv hauv steel, metallurgy, foundry, mechanical equipment, chemical industry and other fields vim nws cov khoom zoo heev. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov muaj peev xwm ntawm cov khoom siv graphite tshiab hauv kev lag luam high-tech xws li lub zog tshiab, kev lag luam nuclear, cov ntaub ntawv hluav taws xob, aerospace thiab kev tiv thaiv tau maj mam tshawb nrhiav, thiab nws tau txiav txim siab los ua ib qho kev pab cuam tsim nyog rau. txoj kev loj hlob ntawm kev lag luam tawm tshiab. Tam sim no, Tuam Tshoj cov khoom lag luam graphite feem ntau yog siv rau hauv cov ntaub ntawv refractory, castings, seals, tshwj xeeb graphite thiab lwm yam teb, ntawm cov khoom siv refractory thiab castings feem ntau siv.
Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam hluav taws xob tshiab, qhov kev thov rau graphite yav tom ntej yuav nce ntxiv.
