Raws li tsab ntawv ceeb toom ntawm Tebchaws Meskas Kev Tshawb Fawb Txog Kev Tshawb Fawb Txog Kev Tshawb Fawb (2014), cov pov thawj muaj peev txheej ntawm cov nplaim hluav taws xob hauv ntiaj teb yog 130 lab tons, ntawm qhov ntawd, cov peev txheej ntawm Brazil yog 58 lab tons, thiab ntawm Tuam Tshoj yog 55 lab tons, qeb duas saum toj kawg nkaus hauv ntiaj teb. Niaj hnub no peb yuav qhia koj txog kev faib thoob ntiaj teb ntawm cov khoom siv flake graphite: los ntawm kev faib thoob ntiaj teb ntawm flake graphite, txawm hais tias ntau lub tebchaws tau pom flake graphite cov zaub mov, tab sis tsis muaj ntau qhov tso nyiaj nrog qee qhov teev muaj rau kev siv, feem ntau yog nyob hauv Suav teb , Brazil, Is Nrias teb, Czech koom pheej, Mexico thiab lwm lub tebchaws.
1. Tuam Tshoj
Raws li kev txheeb cais ntawm Ministry of Land thiab Resources, txog thaum kawg ntawm 2014, Tuam Tshoj cov peev txheej ntawm crystalline graphite yog 20 lab tons, thiab cov npe tshwj tseg tau kwv yees li 220 lab tons, feem ntau xa tawm hauv 20 lub xeev thiab thaj chaw muaj xws li Heilongjiang, Shandong, Sab Hauv Mongolia thiab Sichuan, ntawm Shandong thiab Heilongjiang yog thaj chaw tsim khoom loj. Cov peev txheej ntawm cryptocrystalline graphite hauv Suav teb yog kwv yees li 5 lab tons, thiab cov npe tshwj tseg yog kwv yees li 35 lab tons, uas feem ntau tau faib rau hauv 9 lub xeev thiab thaj chaw uas muaj kev ywj pheej xws li Hunan, Inner Mongolia thiab Jilin, ntawm qhov uas Chenzhou hauv Hunan yog qhov kev mloog zoo qhov chaw ntawm cryptocrystalline graphite.
2.Brazil
Raws li US Geological Survey, Brazil muaj txog 58 lab tons ntawm graphite ore reserves, ntawm uas ntau dua 36 lab tons yog ntuj flake graphite reserves. Brazil cov graphite tso nyiaj feem ntau nyob hauv xeev Minas Gerais thiab Bahia. Qhov zoo tshaj plaws flake graphite tso rau hauv minas Gerais.
3. Is Nrias teb
Is Nrias teb muaj 11 lab tons ntawm cov peev txheej graphite thiab 158 lab tons ntawm cov peev txheej. Muaj 3 thaj tsam ntawm graphite ore, thiab cov graphite ore nrog kev txhim kho kev lag luam tus nqi feem ntau tau faib hauv Andhra Pradesh thiab Orissa.
4. Czech koom pheej
Czech koom pheej yog lub tebchaws uas muaj cov khoom siv flake graphite ntau tshaj plaws nyob hauv Europe. Cov flake graphite tso nyiaj feem ntau yog nyob rau sab qab teb Czech xeev nrog cov ntsiab lus carbon ntawm 15%. Cov flake graphite tso nyiaj hauv cheeb tsam Moravia feem ntau yog microcrystalline number case nrog cov ntsiab lus cov pa roj carbon txog li 35%. 5. Mexico Flake graphite ore pom hauv Mexico yog microcrystalline graphite feem ntau faib hauv Sonora thiab Oaxaca xeev. Hermosillo flake graphite microcrystalline number case tsim tau saj ntawm 65%~ 85%.
