Ngokusho kombiko we-US Geological Survey (2014), izinqolobane eziqinisekisiwe ze-natural flake graphite emhlabeni zingamathani ayizigidi ezingu-130, lapho iBrazil inezinqolobane zamathani ayizigidi ezingu-58 kanti iChina inezinqolobane zamathani ayizigidi ezingu-55, ezibekwe phakathi kweziphezulu emhlabeni. Namuhla, umhleli we-Furuite Graphite uzokutshela ngokusatshalaliswa komhlaba wonke kwezinsiza ze-flake graphite:
Kusukela ekusakazweni komhlaba wonke kwe-flake graphite, yize amazwe amaningi ethole amaminerali e-flake graphite, azikho izinsalela eziningi ezinesilinganiso esithile sokusetshenziswa kwezimboni, ikakhulukazi ezigxile eShayina, eBrazil, eNdiya, eCzech Republic, eMexico nakwamanye amazwe.
1. IShayina
Ngokwezibalo zoMnyango Wezomhlaba Nezinsizakusebenza, kusukela ekupheleni kuka-2014, izindawo zokugcina i-ore ye-graphite ekristalu yaseShayina zaziyizigidi ezingama-20 zamathani, kanti izindawo zokugcina izinsizakusebenza ezitholiwe zaziyizigidi ezingama-220 zamathani, ezazisatshalaliswa kakhulu ezifundazweni ezingama-20 nasezifundeni ezizimele njengeHeilongjiang, Shandong, Inner Mongolia kanye neSichuan, phakathi kwazo, iShandong kanye neHeilongjiang yizindawo ezikhiqiza kakhulu. Izindawo zokugcina i-graphite ye-cryptocrystalline eShayina zingaba yizigidi ezingama-5 zamathani, kanti izindawo zokugcina izinsizakusebenza eziqinisekisiwe zingaba yizigidi ezingama-35 zamathani, ezazisatshalaliswa kakhulu ezifundazweni eziyi-9 nasezifundeni ezizimele okuhlanganisa iHunan, Inner Mongolia kanye neJilin. Phakathi kwazo, iChenzhou, iHunan kukhona ukugcwala kwe-graphite ye-cryptocrystalline.
2. IBrazil
Ngokwezibalo ze-US Geological Survey, izindawo zokugcina i-graphite ore eBrazil zingamathani angaba yizigidi ezingu-58, lapho izindawo zokugcina i-graphite yemvelo zingaphezu kwamathani ayizigidi ezingu-36. Izindawo zokugcina i-graphite eBrazil zisakazwa kakhulu eMinas Gerais naseBahia, kanti izindawo zokugcina i-graphite engcono kakhulu zitholakala eMinas Gerais.
3. INdiya
I-India inezinqolobane ze-graphite ezingamathani ayizigidi eziyi-11 kanye nezinsiza ezingamathani ayizigidi eziyi-158. Kunezingqimba ezintathu zemayini ye-graphite, kanti izimayini ze-graphite ezinenani lentuthuko yezomnotho zisakazwa kakhulu e-Andhra Pradesh nase-Orissa.
4. IRiphabhulikhi yaseCzech
I-Czech Republic iyizwe elinemithombo eminingi kakhulu ye-flake graphite eYurophu. Ama-flake graphite deposits asatshalaliswa kakhulu eNingizimu Czech Republic. Ama-flake graphite deposits esifundeni saseMoravia anokuqukethwe kwe-carbon okungaguquki okungu-15% ikakhulukazi yi-microcrystalline graphite, kanti okuqukethwe kwe-carbon okungaguquki kungaba ngu-35%.
5. IMexico
Izimayini ze-graphite ezi-flake ezitholakale eMexico zonke ziyi-graphite encane e-microcrystalline, ezisatshalaliswa kakhulu eSonora nase-Oaxaca. I-graphite encane e-Hermosillo flake graphite ethuthukisiwe inezinga eliphakathi kuka-65% kuya ku-85%.
