Raws li daim ntawv tshaj tawm ntawm US Geological Survey (2014), cov khoom pov thawj ntawm cov flake graphite ntuj hauv ntiaj teb yog 130 lab tons, uas Brazil muaj cov khoom khaws cia ntawm 58 lab tons thiab Tuam Tshoj muaj cov khoom khaws cia ntawm 55 lab tons, qeb duas ntawm cov saum toj kawg nkaus hauv ntiaj teb. Niaj hnub no, tus editor ntawm Furuite Graphite yuav qhia koj txog kev faib tawm thoob ntiaj teb ntawm cov khoom siv flake graphite:
Los ntawm kev faib tawm thoob ntiaj teb ntawm flake graphite, txawm hais tias ntau lub tebchaws tau tshawb pom cov zaub mov flake graphite, tsis muaj ntau qhov chaw tso nyiaj nrog qee qhov ntsuas rau kev siv hauv kev lag luam, feem ntau yog nyob hauv Suav teb, Brazil, Is Nrias teb, Czech koom pheej, Mexico thiab lwm lub tebchaws.
1. Tuam Tshoj
Raws li cov ntaub ntawv ntawm Ministry of Land and Resources, txij li thaum kawg ntawm xyoo 2014, Tuam Tshoj cov khoom siv crystalline graphite ore reserves yog 20 lab tons, thiab cov khoom siv tau txheeb xyuas yog li ntawm 220 lab tons, feem ntau faib rau hauv 20 lub xeev thiab thaj chaw autonomous xws li Heilongjiang, Shandong, Inner Mongolia thiab Sichuan, ntawm cov uas, Shandong thiab Heilongjiang yog cov chaw tsim khoom tseem ceeb. Cov khoom siv cryptocrystalline graphite hauv Tuam Tshoj yog li ntawm 5 lab tons, thiab cov khoom siv pov thawj tau pov thawj yog li ntawm 35 lab tons, uas feem ntau faib rau hauv 9 lub xeev thiab thaj chaw autonomous xws li Hunan, Inner Mongolia thiab Jilin. Ntawm lawv, Chenzhou, Hunan yog qhov concentration ntawm cryptocrystalline graphite.
2. Brazil
Raws li cov ntaub ntawv ntawm US Geological Survey, cov khoom khaws cia ntawm graphite ore hauv Brazil yog li 58 lab tons, uas cov khoom khaws cia graphite ntuj tshaj 36 lab tons. Cov khoom tso cia graphite hauv Brazil feem ntau yog faib hauv Minas Gerais thiab Bahia, thiab cov khoom tso cia graphite zoo tshaj plaws nyob hauv Minas Gerais.
3. Is Nrias teb
Is Nrias teb muaj cov khoom siv graphite ntawm 11 lab tons thiab cov peev txheej ntawm 158 lab tons. Muaj 3 lub chaw ua graphite, thiab cov chaw ua graphite uas muaj txiaj ntsig zoo rau kev lag luam feem ntau yog muab faib rau hauv Andhra Pradesh thiab Orissa.
4. Czech koom pheej
Lub tebchaws Czech yog lub tebchaws uas muaj cov khoom siv graphite flake ntau tshaj plaws hauv Tebchaws Europe. Cov khoom siv graphite flake feem ntau yog muab faib rau hauv South Czech Republic. Cov khoom siv graphite flake hauv thaj av Moravia nrog cov pa roj carbon ruaj khov ntawm 15% feem ntau yog microcrystalline graphite, thiab cov pa roj carbon ruaj khov yog li 35%.
5. Mexico
Cov chaw zeb graphite flake uas tau tshawb pom hauv Mexico yog cov microcrystalline graphite, feem ntau muab faib rau hauv Sonora thiab Oaxaca. Cov graphite ore microcrystalline graphite uas tau tsim los ntawm Hermosillo muaj qib ntawm 65% txog 85%.
