Sida laga soo xigtay warbixinta US Geological Survey (2014), keydka la xaqiijiyay ee flake graphite dabiiciga ah ee adduunka waa 130 milyan oo tan, oo Brazil ay leedahay kayd dhan 58 milyan oo tan halka Shiinaha uu leeyahay kayd dhan 55 milyan oo tan, taasoo ka mid ah kuwa ugu sarreeya adduunka. Maanta, tifaftiraha Furuite Graphite ayaa kuu sheegi doona qaybinta caalamiga ah ee kheyraadka flake graphite:
Laga soo bilaabo qaybinta caalamiga ah ee flake graphite, inkastoo dalal badan ay heleen macdanta flake graphite, ma jiraan kayd badan oo leh cabbir gaar ah oo loogu talagalay isticmaalka warshadaha, oo inta badan ku urursan Shiinaha, Brazil, Hindiya, Jamhuuriyadda Czech, Mexico iyo dalal kale.
1. Shiinaha
Sida laga soo xigtay tirakoobka Wasaaradda Dhulka iyo Kheyraadka, ilaa dhammaadkii 2014, kaydka macdanta graphite ee Shiinaha wuxuu ahaa 20 milyan oo tan, kaydka kheyraadka la aqoonsaday wuxuu ahaa qiyaastii 220 milyan oo tan, oo inta badan lagu qaybiyay 20 gobol iyo gobollo madax-bannaan sida Heilongjiang, Shandong, Inner Mongolia iyo Sichuan, kuwaas oo ay ka mid yihiin Shandong iyo Heilongjiang oo ah meelaha ugu badan ee wax soo saarka. Kaydka graphite cryptocrystalline ee Shiinaha waa qiyaastii 5 milyan oo tan, kaydka kheyraadka la xaqiijiyayna waa qiyaastii 35 milyan oo tan, kuwaas oo inta badan lagu qaybiyo 9 gobol iyo gobollo madax-bannaan oo ay ku jiraan Hunan, Inner Mongolia iyo Jilin. Kuwaas waxaa ka mid ah Chenzhou, Hunan waa isku-darka graphite cryptocrystalline.
2. Brazil
Sida laga soo xigtay tirakoobka Sahanka Juqraafiga Mareykanka, kaydka macdanta graphite ee Brazil waa qiyaastii 58 milyan oo tan, kuwaas oo kaydka graphite dabiiciga ah uu ka badan yahay 36 milyan oo tan. Kaydka graphite ee Brazil waxaa inta badan lagu qaybiyaa Minas Gerais iyo Bahia, kaydka graphite ee ugu fiicanna wuxuu ku yaal Minas Gerais.
3. Hindiya
Hindiya waxay leedahay keyd graphite ah oo gaaraya 11 milyan oo tan iyo kheyraad dhan 158 milyan oo tan. Waxaa jira 3 suumanka macdanta graphite, macdanta graphite-ka oo leh qiime horumarineed oo dhaqaale ayaa inta badan ku baahsan Andhra Pradesh iyo Orissa.
4. Jamhuuriyadda Czech
Jamhuuriyadda Czech waa dalka leh kheyraadka ugu badan ee flake graphite ee Yurub. Kaydka flake graphite waxaa inta badan lagu qaybiyaa Jamhuuriyadda Koonfureed ee Czech. Kaydka flake graphite ee gobolka Moravia oo leh kaarboon go'an oo 15% ah ayaa inta badan ah graphite microcrystalline ah, kaarboon go'anna waa qiyaastii 35%.
5. Meksiko
Macdanta graphite-ka ee laga helay Mexico dhammaantood waa microcrystalline graphite, oo inta badan ku baahsan Sonora iyo Oaxaca. Macdanta graphite-ka ee Hermosillo ee la sameeyay waxay leedahay heer u dhexeeya 65% ilaa 85%.
