Raws li tsab ntawv ceeb toom ntawm US Geological Survey (2014), cov pov thawj reserves ntawm ntuj flake graphite nyob rau hauv lub ntiaj teb no yog 130 lab tons, uas Brazil muaj reserves ntawm 58 lab tons thiab Tuam Tshoj muaj reserves ntawm 55 lab tons, qeb ntawm cov saum toj kawg nkaus. hauv ntiaj teb no. Niaj hnub no, tus editor ntawm Furuite Graphite yuav qhia koj txog kev faib thoob ntiaj teb ntawm flake graphite cov peev txheej:
Los ntawm thoob ntiaj teb kev faib tawm ntawm flake graphite, txawm hais tias ntau lub teb chaws tau tshawb pom flake graphite minerals, tsis muaj ntau cov deposits nrog ib tug tej yam scale rau industrial siv, mas concentrated nyob rau hauv Tuam Tshoj, Brazil, Is Nrias teb, lub Czech koom pheej, Mexico thiab lwm lub teb chaws.
1. Suav teb
Raws li kev txheeb cais ntawm Ministry of Land thiab Resources, txij li thaum kawg ntawm 2014, Tuam Tshoj lub crystalline graphite ore reserves yog 20 lab tons, thiab cov ntaub ntawv pov thawj muaj txog 220 lab tons, feem ntau faib nyob rau hauv 20 lub xeev thiab autonomous cheeb tsam xws li Heilongjiang, Shandong, Inner Mongolia thiab Sichuan, ntawm cov uas, Shandong thiab Heilongjiang yog cov chaw tsim khoom loj. Cov reserves ntawm cryptocrystalline graphite nyob rau hauv Tuam Tshoj yog kwv yees li 5 lab tons, thiab cov pov thawj cov peev txheej reserves yog hais txog 35 lab tons, uas yog feem ntau faib nyob rau hauv 9 lub xeev thiab autonomous cheeb tsam xws li Hunan, Inner Mongolia thiab Jilin. Ntawm lawv, Chenzhou, Hunan yog qhov concentration ntawm cryptocrystalline graphite.
2. Brazil
Raws li kev txheeb cais ntawm US Geological Survey, cov reserves ntawm graphite ore nyob rau hauv Brazil yog hais txog 58 lab tons, ntawm uas ntuj flake graphite reserves tshaj 36 lab tons. Graphite deposits nyob rau hauv Brazil feem ntau yog faib nyob rau hauv Minas Gerais thiab Bahia, thiab qhov zoo tshaj plaws flake graphite deposits nyob rau hauv Minas Gerais.
3. Is Nrias teb
Is Nrias teb muaj graphite reserves ntawm 11 lab tons thiab cov peev txheej ntawm 158 lab tons. Muaj 3 graphite mine siv, thiab cov graphite mines nrog kev txhim kho kev lag luam yog feem ntau faib hauv Andhra Pradesh thiab Orissa.
4. Czech koom pheej
Czech koom pheej yog lub teb chaws uas muaj ntau tshaj flake graphite peev nyob rau hauv cov teb chaws Europe. Flake graphite deposits feem ntau yog muab faib rau hauv South Czech koom pheej. Lub flake graphite deposits nyob rau hauv Moravia cheeb tsam nrog ib tug taag carbon ntsiab lus ntawm 15% yog mas microcrystalline graphite, thiab cov ntsiab lus taag carbon yog li ntawm 35%.
5. Mexico
Cov flake graphite mines uas tau pom nyob rau hauv Mexico yog tag nrho cov microcrystalline graphite, feem ntau faib hauv Sonora thiab Oaxaca. Tus tsim Hermosillo flake graphite ore microcrystalline graphite muaj qib ntawm 65% mus rau 85%.
