Sida laga soo xigtay warbixinta The US Geological Survey (2014), keydka la xaqiijiyay ee garaafka dabiiciga ah ee adduunka waa 130 milyan oo tan, oo ay ka mid yihiin, kaydka Brazil waa 58 milyan oo tan, iyo kan Shiinaha waa 55 milyan oo tan, qiimeynta ugu sareysa adduunka. Maanta waxaan kuu sheegi doonnaa qaybinta caalamiga ah ee kheyraadka garaafka flake: laga soo bilaabo qeybinta caalamiga ah ee garaafka flake, in kasta oo dalal badan ay heleen macdanta garaafyada garaafka, laakiin ma jiraan kaydyo badan oo leh cabbir gaar ah oo loo heli karo adeegsiga warshadaha, oo inta badan ku urursan Shiinaha , Brazil, India, Czech Republic, Mexico iyo wadamo kale.
1. Shiinaha
Marka loo eego tirakoobka Wasaaradda Dhulka iyo Kheyraadka, dhammaadkii 2014, kaydka Shiinaha ee garaafka crystalline wuxuu ahaa 20 milyan oo tan, kaydka la aqoonsadayna wuxuu ahaa ilaa 220 milyan oo tan, oo inta badan lagu qaybiyey 20 gobol iyo gobollada ismaamulada sida Heilongjiang, Shandong, gudaha Mongolia iyo Sichuan, oo ay ka mid yihiin Shandong iyo Heilongjiang waa meelaha wax soo saarka ugu weyn. Kaydadka garaafyada loo yaqaan 'cryptocrystalline graphite' ee Shiinaha waa qiyaastii 5 milyan oo tan, kaydka la aqoonsadayna waa qiyaastii 35 milyan oo tan, kuwaas oo inta badan lagu qaybiyo 9 gobol iyo gobollada ismaamulada ah sida Hunan, Inner Mongolia iyo Jilin, oo ay ka mid tahay Chenzhou ee Hunan meesha garaafka cryptocrystalline.
2.Brazil
Sida laga soo xigtay Sahanka Juqraafiga ee Mareykanka, Brazil waxay leedahay ilaa 58 milyan oo tan oo kaydka macdanta garaafka ah, kuwaas oo in ka badan 36 milyan oo tan ay yihiin kaydadka garaafyada dabiiciga ah ee dabiiciga ah. Kaydadka garaafyada ee Brazil ayaa badiyaa ku yaal gobollada Minas Gerais iyo Bahia. Kaydinta garaafyada ugu fiican waxay ku taal minas Gerais.
3. Hindiya
Hindiya waxay leedahay 11 milyan oo tan oo kaydka garaafka ah iyo 158 milyan oo tan oo kheyraad ah. Waxaa jira 3 aag oo ka mid ah macdanta garaafka, iyo macdanta garaafyada leh qiimaha kobcinta dhaqaalaha waxaa inta badan lagu qaybiyaa Andhra Pradesh iyo Orissa.
4. Jamhuuriyadda Czech
Jamhuuriyadda Czech waa waddanka leh kheyraadka garaafyada ugu badan ee Yurub. Kaydadka garaafyada cadceedda ayaa badiyaa ku yaal gobolka koonfurta Czech oo leh kaarboon go'an oo ah 15%. Kaydadka garaafyada ee flake ee gobolka Moravia inta badan waa khad microcrystalline oo leh kaarboon joogto ah oo qiyaastii ah 35%. 5. Meksiko Macdanta graphite flake ee laga helo Meksiko waa garaafka microcrystalline oo inta badan lagu qaybiyo gobollada Sonora iyo Oaxaca. Qalinka hermosillo flake graphite microcrystalline wuxuu leeyahay dhadhan 65%~ 85%.
