Ngokwengxelo ye-US Geological Survey (2014), iindawo ezigciniweyo zegrafiti yendalo ye-flake emhlabeni ziitoni ezili-130 lezigidi, apho iBrazil ineetoni ezingama-58 lezigidi kwaye iChina ineetoni ezingama-55 lezigidi, ezibekwe phakathi kwezona ziphezulu kwihlabathi. Namhlanje, umhleli we-Furuite Graphite uza kukuxelela malunga nokusasazwa kwezixhobo zegrafiti ye-flake kwihlabathi liphela:
Ukususela ekusasazweni kwe-flake graphite kwihlabathi liphela, nangona amazwe amaninzi efumanise izimbiwa ze-flake graphite, azikho iidiphozithi ezininzi ezinesikali esithile sokusetyenziswa kwimizi-mveliso, ikakhulu zigxile eTshayina, eBrazil, eIndiya, kwiRiphabliki yaseCzech, eMexico nakwamanye amazwe.
1. ITshayina
Ngokwezibalo zeSebe leMicimbi yoMhlaba neMithombo, ekupheleni kuka-2014, iindawo zokugcina i-ore ze-crystalline graphite zaseTshayina zaziziitoni ezingama-20 ezigidi, kwaye iindawo zokugcina iziseko ezichongiweyo zaziziitoni ezingama-220 ezigidi, ikakhulu zisasazwe kumaphondo angama-20 nakwiindawo ezizimeleyo ezifana neHeilongjiang, iShandong, i-Inner Mongolia kunye neSichuan, phakathi kwazo, iShandong kunye neHeilongjiang zezona ndawo zivelisa kakhulu. Iindawo zokugcina i-cryptocrystalline graphite eTshayina zimalunga nezigidi ezi-5 zeetoni, kwaye iindawo zokugcina iziseko eziqinisekisiweyo zimalunga nezigidi ezingama-35 zeetoni, ezisasazwe kakhulu kumaphondo ali-9 nakwiindawo ezizimeleyo kuquka iHunan, i-Inner Mongolia kunye neJilin. Phakathi kwazo, iChenzhou, iHunan kukho uxinano lwe-cryptocrystalline graphite.
2. IBrazil
Ngokwezibalo ze-US Geological Survey, iindawo zokugcina i-graphite ore eBrazil zimalunga ne-58 yezigidi zeetoni, apho iindawo zokugcina i-graphite yendalo zidlula i-36 yezigidi zeetoni. Ii-graphite deposits eBrazil zisasazwa kakhulu eMinas Gerais naseBahia, kwaye ezona depositi ze-graphite zibalaseleyo zifumaneka eMinas Gerais.
3. IIndiya
I-India ineendawo zokugcina igrafiti eziziitoni ezili-11 lezigidi kunye nezixhobo eziziitoni ezili-158 lezigidi. Kukho iibhanti ezintathu zemigodi yegrafiti, kwaye imigodi yegrafiti enexabiso lophuhliso loqoqosho isasazwa kakhulu e-Andhra Pradesh nase-Orissa.
4. IRiphabliki yaseCzech
IRiphabliki yaseCzech lelona lizwe linemithombo emininzi yegrafiti ye-flake eYurophu. Iidiphozithi zegrafiti ye-flake zisasazwa kakhulu kwiRiphabliki yaseMzantsi Czech. Iidiphozithi zegrafiti ye-flake kummandla waseMoravia ezinomxholo wekhabhoni ozinzileyo we-15% ikakhulu ziigrafiti ze-microcrystalline, kwaye umxholo wekhabhoni ozinzileyo umalunga ne-35%.
5. IMexico
Iimigodi zegrafiti ezifunyanisiweyo eMexico zonke ziyigrafiti ye-microcrystalline, esasazwa kakhulu eSonora nase-Oaxaca. Igrafiti ye-ore microcrystalline ephuhlisiweyo yeHermosillo flake graphite inomgangatho we-65% ukuya kwi-85%.
