Ngokusho kombiko we-United States Geological Survey (2014), izinqolobane eziqinisekisiwe ze-flake graphite yemvelo emhlabeni zingamathani ayizigidi ezingu-130, phakathi kwazo, izinqolobane zaseBrazil zingamathani ayizigidi ezingu-58, kanti ezaseShayina zingamathani ayizigidi ezingu-55, okubalwa phezulu emhlabeni. Namuhla sizokutshela ngokusatshalaliswa komhlaba wonke kwezinsiza ze-flake graphite: kusukela ekusatshalalisweni komhlaba wonke kwe-flake graphite, yize amazwe amaningi ethole amaminerali e-flake graphite, kodwa azikho izinqwaba zezingqolobane ezinesilinganiso esithile esitholakalayo sokusetshenziswa kwezimboni, ikakhulukazi ezigxile eShayina, eBrazil, eNdiya, eCzech Republic, eMexico nakwamanye amazwe.
1. IShayina
Ngokwezibalo zoMnyango Wezomhlaba Nezinsizakusebenza, ekupheleni kuka-2014, izindawo zokugcina ze-graphite ekristalu eShayina zaziyizigidi ezingama-20 zamathani, kanti izindawo zokugcina ezitholiwe zaziyizigidi ezingama-220 zamathani, ezazisatshalaliswa kakhulu ezifundazweni ezingama-20 nasezifundeni ezizimele njengeHeilongjiang, Shandong, Inner Mongolia kanye neSichuan, phakathi kwazo iShandong neHeilongjiang kuyizindawo zokukhiqiza eziyinhloko. Izindawo zokugcina ze-graphite ekristalu eShayina zingaba yizigidi ezingama-5 zamathani, kanti izindawo zokugcina ezitholiwe zingaba yizigidi ezingama-35 zamathani, ezazisatshalaliswa kakhulu ezifundazweni eziyi-9 nasezifundeni ezizimele njengeHunan, Inner Mongolia kanye neJilin, phakathi kwazo iChenzhou eHunan iyindawo ehlanganisiwe ye-graphite ekristalu.
2. IBrazil
Ngokusho kwe-US Geological Survey, iBrazil inamathani angaba yizigidi ezingu-58 ezinqolobane ze-graphite ore, lapho amathani angaphezu kwezigidi ezingu-36 kuzo ayizinqolobane zemvelo ze-flake graphite. Ama-graphite deposit aseBrazil atholakala kakhulu ezifundazweni zaseMinas Gerais naseBahia. Ama-graphite graphite deposit amahle kakhulu atholakala eMinas Gerais.
3. INdiya
I-India inamathani ayizigidi ezingu-11 ezinqolobane ze-graphite kanye namathani ayizigidi ezingu-158 ezinsiza. Kunezindawo ezintathu ze-graphite ore, kanti i-graphite ore enenani lentuthuko yezomnotho isatshalaliswa kakhulu e-Andhra Pradesh nase-Orissa.
4. iRiphabhulikhi yaseCzech
I-Czech Republic iyizwe elinemithombo eminingi kakhulu ye-flake graphite eYurophu. Ama-flake graphite deposits atholakala kakhulu esifundazweni saseningizimu yeCzech ngokuqukethwe kwe-carbon okungaguquki okungu-15%. Ama-flake graphite deposits esifundeni saseMoravia ikakhulukazi ayinki encane ekristalu enokuqukethwe kwe-carbon okungaguquki okungu-35%. 5. I-Mexico I-flake graphite ore etholakala eMexico iyi-microcrystalline graphite esakazwa kakhulu emazweni aseSonora nase-Oaxaca. I-hermosillo flake graphite microcrystalline inkino ethuthukisiwe inambitheka engu-65% ~ 85%.
