Sida lagu sheegay warbixinta The United States Geological Survey (2014), kaydka la xaqiijiyay ee graphite flake dabiiciga ah ee dunida waa 130 million tons, kuwaas oo, kaydka Brazil waa 58 million tons, iyo kan Shiinaha waa 55 million tons, darajada sare ee adduunka. Maanta waxaan kuu sheegi doonaa oo ku saabsan qaybinta caalamiga ah ee khayraadka graphite flake: laga bilaabo qaybinta caalamiga ah ee graphite flake, inkastoo dalal badan ayaa laga helay macdanta graphite flake, laakiin ma jiraan kayd badan oo leh miisaan gaar ah diyaar u ah isticmaalka warshadaha, inta badan ku urursan ee Shiinaha, Brazil, India, Czech Republic, Mexico iyo dalal kale.
1. Shiinaha
Marka loo eego tirakoobka Wasaaradda Dhulka iyo Kheyraadka, dhammaadka 2014, kaydka Shiinaha ee graphite crystalline wuxuu ahaa 20 milyan oo tan, kaydka la aqoonsaday wuxuu ahaa qiyaastii 220 milyan oo tan, oo inta badan loo qaybiyay gobollada 20 iyo gobollada ismaamulka sida Heilongjiang, Shandong, Mongolia gudaha iyo wax soo saarka ee Silongjiang, oo ka mid ah meelaha ugu muhiimsan ee Shandong. Kaydka graphite cryptocrystalline ee Shiinaha ayaa ku saabsan 5 milyan oo tan, kaydadka la aqoonsadayna waa qiyaastii 35 milyan oo tan, kuwaas oo inta badan lagu qaybiyo gobollada 9 iyo gobollada ismaamulka sida Hunan, Mongolia gudaha iyo Jilin, kuwaas oo Chenzhou ee Hunan uu yahay meesha ugu badan ee graphite cryptocrystalline.
2.Brazil
Sida laga soo xigtay Sahanka Juquraafi ee Maraykanka, Brazil waxay leedahay qiyaastii 58 milyan oo tan oo kayd garaafeed ah, kuwaas oo in ka badan 36 milyan oo tan ay yihiin kaydka garaafyada dabiiciga ah. Kaydka garaafka ee Brazil waxay inta badan ku yaalaan gobolada Minas Gerais iyo Bahia. Kaydka garaafiga flake ugu fiican waxay ku yaalaan minas Gerais.
3. Hindiya
Hindiya waxay leedahay 11 milyan oo tan oo kayd garaafeed ah iyo 158 milyan oo tan oo khayraad ah. Waxaa jira 3 aag oo graphite ore ah, iyo graphite ore qiimaha horumarinta dhaqaalaha waxaa inta badan loo qaybiyey Andhra Pradesh iyo Orissa.
4. Jamhuuriyadda Czech
Czech Republic waa dalka ugu kheyraadka badan ee graphite flake ee Yurub. Kaydka garaafyada flake waxay inta badan ku yaalaan koonfurta Czech oo leh kaarboon go'an oo ah 15%. Kaydka garaafyada flake ee gobolka Moravia waa khad microcrystalline ah oo leh kaarboon go'an oo qiyaastii 35%. 5. Mexico Macdanta garaafyada flake ee laga helo Mexico waa garaafyada microcrystalline oo inta badan lagu qaybiyo gobolada Sonora iyo Oaxaca. Khadka garaafiga ah ee loo yaqaan 'hermosillo flake graphite microcrystalline khad' wuxuu leeyahay dhadhan 65% ~ 85%.
