Raws li tsab ntawv tshaj tawm ntawm Asmeskas Tebchaws Asmeskas Geological (2014), cov ntaub ntawv pov thawj los ntawm 58 lab tons, uas muaj cov peev nyiaj ntawm 55 lab tons, qeb duas, qeb duas ntawm sab saum toj hauv lub ntiaj teb. Niaj hnub no, tus kws kho dua ntawm cov pluallite graphite yuav qhia koj txog kev faib hluav taws xob thoob ntiaj teb:
Los ntawm kev faib hluav taws xob ntawm hluav taws xob graphite, txawm hais tias ntau lub teb chaws tau pom flake graphite minerals, tsuas yog muaj ntau yam kev lag luam, Brazil, Is Nrias teb, Mexico thiab lwm lub tebchaws.
1. Suav
Raws li kev txheeb cais ntawm Ministry of Av thiab cov peev txheej, SHERVOY RAWS LI TXOJ CAI Lub reserves ntawm cryptocrystalline graphite nyob hauv Suav teb yog kwv yees li 55 lab cov cheeb tsam thiab cov chaw ua pov thawj tau suav nrog HUNAN, sab hauv Mongolia thiab Jilin. Ntawm lawv, Curzhou, Hunan yog kev sib haum xeeb ntawm cryptocrystalline graphite.
2. Brazil
According to the statistics of the US Geological Survey, the reserves of graphite ore in Brazil are about 58 million tons, of which natural flake graphite reserves exceed 36 million tons. Graphite Cov nyiaj hauv Brazil yog feem ntau muab faib rau hauv Minas Gerais thiab Bahia, thiab tus zoo nkauj flake graphite tso nyiaj yog nyob hauv Minas Gerais.
3. Is Nrias teb
Is Nrias teb muaj cov peev xwm graphite ntawm 11 lab tons thiab cov khoom siv ntawm 158 lab tons. Muaj 3 graphite kuv cov siv tawv, thiab graphite Mines nrog kev txhim kho kev lag luam tus nqi feem ntau tau muab faib rau hauv Andhra Pradesh thiab Orissa.
4. Czech koom pheej
Czech koom pheej yog lub teb chaws uas muaj ntau tshaj plaws flake graphite cov peev txheej hauv Tebchaws Europe. Txoj kev tso quav flake feem ntau muab faib rau South Czech koom pheej. Txoj kev tso quav flake tso rau hauv thaj av Moravia nrog cov ntsiab lus carbon monoman ntawm 15% yog tsuas yog microcrystalline graphite, thiab cov cov ntsiab lus carbon monoxide tsau yog li 35%.
5. Mexico
Tus pas flake graphite Mines uas tau pom nyob hauv Mexico yog tag nrho cov microcrystalline graphite, feem ntau muab cais nyob rau hauv sonora thiab oaxaca. Tus tsim Hermosillo flake graphite ore microcrystalline graphite muaj qib 65% txog 85%.
