Raws li daim ntawv tshaj tawm ntawm THE United States Geological Survey (2014), cov khoom pov thawj ntawm cov graphite flake natural hauv ntiaj teb yog 130 lab tons, ntawm cov uas, cov khoom khaws cia ntawm Brazil yog 58 lab tons, thiab ntawm Tuam Tshoj yog 55 lab tons, qeb duas sab saum toj hauv ntiaj teb. Hnub no peb yuav qhia koj txog kev faib tawm thoob ntiaj teb ntawm cov khoom siv graphite flake: los ntawm kev faib tawm thoob ntiaj teb ntawm flake graphite, txawm hais tias ntau lub tebchaws tau pom cov zaub mov graphite flake, tab sis tsis muaj ntau qhov chaw tso nyiaj nrog qee qhov ntsuas muaj 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, thaum kawg ntawm xyoo 2014, Tuam Tshoj cov khoom siv crystalline graphite yog 20 lab tons, thiab cov khoom siv tau txheeb xyuas yog kwv yees li 220 lab tons, feem ntau faib rau hauv 20 lub xeev thiab thaj chaw ywj pheej xws li Heilongjiang, Shandong, Inner Mongolia thiab Sichuan, ntawm cov uas Shandong thiab Heilongjiang yog thaj chaw tsim khoom tseem ceeb. Cov khoom siv cryptocrystalline graphite hauv Tuam Tshoj yog kwv yees li 5 lab tons, thiab cov khoom siv tau txheeb xyuas yog kwv yees li 35 lab tons, uas feem ntau faib rau hauv 9 lub xeev thiab thaj chaw ywj pheej xws li Hunan, Inner Mongolia thiab Jilin, ntawm cov uas Chenzhou hauv Hunan yog qhov chaw muaj cryptocrystalline graphite.
2. Brazil
Raws li US Geological Survey, Brazil muaj kwv yees li 58 lab tons ntawm graphite ore reserves, uas ntau dua 36 lab tons yog cov khoom siv graphite flake natural. Brazil cov graphite deposits feem ntau nyob hauv xeev Minas Gerais thiab Bahia. Cov flake graphite deposits zoo tshaj plaws nyob hauv minas Gerais.
3. Is Nrias teb
Is Nrias teb muaj 11 lab tons ntawm graphite reserves thiab 158 lab tons ntawm cov peev txheej. Muaj 3 thaj chaw ntawm graphite ore, thiab graphite ore nrog kev txhim kho kev lag luam feem ntau yog faib hauv Andhra Pradesh thiab Orissa.
4. lub koom pheej Czech
Lub koom pheej Czech yog lub tebchaws uas muaj cov khoom siv graphite flake ntau tshaj plaws hauv Tebchaws Europe. Cov chaw tso graphite flake feem ntau nyob hauv lub xeev Czech sab qab teb nrog cov pa roj carbon ruaj khov ntawm 15%. Cov chaw tso graphite flake hauv thaj av Moravia feem ntau yog cov kua mem microcrystalline nrog cov pa roj carbon ruaj khov ntawm kwv yees li 35%. 5. Mexico Cov graphite flake ore pom hauv Mexico yog microcrystalline graphite feem ntau faib hauv Sonora thiab Oaxaca xeev. Cov kua mem hermosillo flake graphite microcrystalline uas tsim tau muaj saj ntawm 65% ~ 85%.
