Raws li tsab ntawv ceeb toom ntawm THE United States Geological Survey (2014), cov pov thawj reserves ntawm ntuj flake graphite nyob rau hauv lub ntiaj teb no yog 130 lab tons, cov uas, lub reserves ntawm Brazil yog 58 lab tons, thiab hais tias ntawm Tuam Tshoj yog 55 lab tons, qeb duas nyob rau hauv lub ntiaj teb no. Niaj hnub no peb 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 pom flake graphite minerals, tab sis tsis muaj ntau cov deposits nrog ib tug tej scale muaj nyob rau hauv industrial siv, feem ntau yog concentrated nyob rau hauv Tuam Tshoj, Brazil, India, Czech koom pheej, Mexico thiab lwm lub teb chaws.
1. Suav teb
Raws li kev txheeb cais ntawm Ministry of Land thiab Resources, thaum kawg ntawm xyoo 2014, Tuam Tshoj cov khoom khaws cia ntawm crystalline graphite yog 20 lab tons, thiab cov ntaub ntawv pov thawj muaj txog 220 lab tons, feem ntau faib rau hauv 20 lub xeev thiab thaj chaw uas muaj kev ywj pheej xws li Heilongjiang, Shandong, Inner Mongolia thiab Sichuan, thiab cov khoom tseem ceeb ntawm cov cheeb tsam ntawm Heilongjiang. Cov reserves ntawm cryptocrystalline graphite nyob rau hauv Suav teb yog kwv yees li 5 lab tons, thiab cov ntaub ntawv pov thawj muaj 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, uas Chenzhou nyob rau hauv Hunan yog lub concentrated 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 tshaj 36 lab tons yog ntuj flake graphite reserves. Brazil cov graphite deposits yog nyob rau hauv lub xeev ntawm Minas Gerais thiab Bahia. Qhov zoo tshaj plaws flake graphite deposits nyob rau 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 cov graphite ore 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 nyob rau sab qab teb Czech xeev nrog cov ntsiab lus ntawm 15%. Cov flake graphite deposits nyob rau hauv cheeb tsam Moravia yog tsuas yog microcrystalline number case nrog ib tug tsau cov ntsiab lus ntawm txog 35%. 5. Mexico Lub flake graphite ore pom nyob rau hauv Mexico yog microcrystalline graphite feem ntau faib hauv Sonora thiab Oaxaca xeev. Tus tsim hermosillo flake graphite microcrystalline number case muaj saj ntawm 65% ~ 85%.
