Malinga ndi lipoti la The United States Geological Survey (2014), malo osungidwa a graphite achilengedwe padziko lapansi ndi matani 130 miliyoni, mwa omwe, nkhokwe ku Brazil ndi matani 58 miliyoni, ndipo China ndi matani 55 miliyoni, kusanja pamwamba padziko lapansi. Lero tikukuuzani za kufalikira kwapadziko lonse kwa zida za graphite: kuchokera pakufalitsa kwa graphite kwa flake, ngakhale mayiko ambiri apeza miyala ya graphite mchere, koma kulibe madipoziti ambiri omwe ali ndi gawo linalake logwiritsidwa ntchito m'mafakitale, makamaka ku China , Brazil, India, Czech Republic, Mexico ndi mayiko ena.
1. China
Malinga ndi ziwerengero za Unduna wa Zachuma, pofika kumapeto kwa 2014, malo osungidwa a China a crystalline graphite anali matani 20 miliyoni, ndipo malo osungidwawo anali pafupifupi matani 220 miliyoni, makamaka omwe amagawidwa m'maboma 20 ndi madera odziyimira pawokha monga Heilongjiang, Shandong, Inner Mongolia ndi Sichuan, pomwe Shandong ndi Heilongjiang ndiomwe amapanga. Malo osungidwa a cryptocrystalline graphite ku China ali pafupifupi matani 5 miliyoni, ndipo malo osungidwawo ali pafupifupi matani 35 miliyoni, omwe amagawidwa makamaka m'zigawo 9 ndi madera odziyimira pawokha monga Hunan, Inner Mongolia ndi Jilin, pakati pawo Chenzhou ku Hunan ndizokhazikika malo a cryptocrystalline graphite.
2. Brazil
Malingana ndi US Geological Survey, Brazil ili ndi matani 58 miliyoni a miyala ya graphite, yomwe matani ake opitilira 36 miliyoni ndi malo osungidwa a graphite. Ma graphite aku Brazil amapezeka makamaka ku Minas Gerais ndi Bahia. Ma flake graphite abwino kwambiri amapezeka ku minas Gerais.
3. India
India ili ndi matani 11 miliyoni a malo osungidwa a graphite ndi matani 158 miliyoni azinthu. Pali magawo atatu a miyala ya graphite, ndipo miyala ya graphite yomwe ili ndi phindu lachitukuko imagawidwa makamaka ku Andhra Pradesh ndi Orissa.
4. dziko la Czech
Czech Republic ndi dziko lokhala ndi zida zambiri za graphite ku Europe. Ma flake graphite deposits amapezeka makamaka kum'mwera kwa dziko la Czech okhala ndi mpweya wokwanira 15%. Flake graphite amasunga m'dera la Moravia makamaka ndi inki yama microcrystalline yokhala ndi mpweya wokwanira pafupifupi 35%. 5. Mexico Mafuta a graphite omwe amapezeka ku Mexico ndi microcrystalline graphite omwe amagawidwa makamaka m'maiko a Sonora ndi Oaxaca. Inki yotchedwa hermosillo flake graphite microcrystalline ink imakhala ndi kukoma kwa 65% ~ 85%.
