Malinga ndi lipoti la The United States Geological Survey (2014), nkhokwe zotsimikizirika za graphite zachilengedwe padziko lapansi ndi matani 130 miliyoni, pomwe nkhokwe za Brazil ndi matani 58 miliyoni, ndi China ndi matani 55 miliyoni, kukhala pamwamba padziko lonse lapansi. Lero tikuwuzani za kugawidwa kwapadziko lonse kwa zinthu zamtundu wa graphite: kuchokera ku kugawidwa kwapadziko lonse kwa flake graphite, ngakhale mayiko ambiri apeza mchere wa flake graphite, koma palibe madipoziti ambiri omwe ali ndi mlingo winawake wogwiritsidwa ntchito m'mafakitale, makamaka ku China. , Brazil, India, Czech Republic, Mexico ndi mayiko ena.
1. China
Malinga ndi ziwerengero za Unduna wa Land and Resources, pofika kumapeto kwa 2014, nkhokwe zaku China za crystalline graphite zinali matani 20 miliyoni, ndipo malo omwe adadziwika anali pafupifupi matani 220 miliyoni, omwe amagawidwa m'zigawo 20 ndi zigawo zodziyimira pawokha monga Heilongjiang, Shandong, Inner Mongolia ndi Sichuan, pakati pawo Shandong ndi Heilongjiang ndi malo akuluakulu opanga. Zosungirako za cryptocrystalline graphite ku China ndi pafupifupi matani 5 miliyoni, ndipo nkhokwe zomwe zimadziwika ndi pafupifupi matani 35 miliyoni, omwe amagawidwa makamaka m'zigawo 9 ndi zigawo zodziyimira pawokha monga Hunan, Inner Mongolia ndi Jilin, pakati pa Chenzhou ku Hunan. malo a cryptocrystalline graphite.
2.Brazil
Malinga ndi a US Geological Survey, dziko la Brazil lili ndi matani pafupifupi 58 miliyoni a miyala yamtengo wapatali ya graphite, pomwe matani oposa 36 miliyoni ndi malo achilengedwe a graphite. Madipoziti a graphite ku Brazil makamaka amakhala ku Minas Gerais ndi Bahia. Malo abwino kwambiri a flake graphite ali ku Minas Gerais.
3. India
India ili ndi matani 11 miliyoni a graphite reserve ndi matani 158 miliyoni azinthu. Pali madera atatu a graphite ore, ndipo miyala ya graphite yomwe ili ndi phindu lachitukuko chachuma imagawidwa makamaka ku Andhra Pradesh ndi Orissa.
4. Czech Republic
Czech Republic ndi dziko lomwe lili ndi zinthu zambiri zamtundu wa graphite ku Europe. Ma flake graphite deposits amapezeka makamaka kum'mwera kwa dziko la Czech komwe amakhala ndi mpweya wokhazikika wa 15%. The flake graphite madipoziti m'dera Moravia makamaka microcrystalline inki ndi zokhazikika mpweya zili za 35%. 5. Mexico Mwala wa flake graphite ore womwe umapezeka ku Mexico ndi microcrystalline graphite yomwe imagawidwa makamaka ku Sonora ndi Oaxaca. The otukuka hermosillo flake graphite microcrystalline inki ali ndi kukoma kwa 65% ~ 85%.
