Wahi a ka hōʻike a ka United States Geological Survey (2014), ʻo ka mālama ʻia ʻana o ka graphite flake maoli i ka honua he 130 miliona mau tons, ma waena o ia mea, ʻo ka mālama ʻana o Brazil he 58 miliona mau tons, a ʻo Kina he 55 miliona mau tons. ke kūlana kiʻekiʻe ma ka honua. I kēia lā, e haʻi mākou iā ʻoe e pili ana i ka hāʻawi honua ʻana i nā kumuwaiwai flake graphite: mai ka hoʻohele honua ʻana o ka flake graphite, ʻoiai ua loaʻa i nā ʻāina he nui nā minerale flake graphite, akā ʻaʻole nui nā waihona me kahi pālākiō i loaʻa no ka hoʻohana ʻana i ka ʻoihana, ka mea nui i Kina. , Palakila, India, Czech Republic, Mexico a me nā ʻāina ʻē aʻe.
1. Kina
Wahi a ka ʻikepili o ka Ministry of Land and Resources, ma ka hopena o 2014, ʻo 20 miliona mau tons ka mālama ʻana o Kina o ka crystalline graphite, a ʻo nā mea i ʻike ʻia ma kahi o 220 miliona mau tons, ka mea i māhele ʻia ma 20 mau panalāʻau a me nā ʻāina autonomous e like me Heilongjiang, ʻO Shandong, Inner Mongolia a me Sichuan, ma waena o Shandong a me Heilongjiang nā wahi hana nui. ʻO ka mālama ʻana o ka cryptocrystalline graphite ma Kina ma kahi o 5 miliona mau tons, a ʻo nā mea mālama i ʻike ʻia ma kahi o 35 miliona mau tons, ka mea i hoʻolaha nui ʻia ma 9 mau panalāʻau a me nā ʻāina autonomous e like me Hunan, Inner Mongolia a me Jilin, a ma waena o Chenzhou ma Hunan ka mea nui. wahi o ka cryptocrystalline graphite.
2.Brazila
Wahi a ka US Geological Survey, aia ʻo Brazil ma kahi o 58 miliona mau tons o ka graphite ore reserves, a ʻoi aku ma mua o 36 miliona mau tons he natural flake graphite reserves. Aia nā waihona graphite o Brazil ma nā mokuʻāina ʻo Minas Gerais a me Bahia. Aia nā waihona graphite flake maikaʻi loa ma minas Gerais.
3. Inia
Loaʻa iā India he 11 miliona tons o nā waihona graphite a me 158 miliona tons o nā kumuwaiwai. Aia he 3 mau ʻāpana o ka graphite ore, a ʻo ka graphite ore me ka waiwai hoʻomohala hoʻokele waiwai e māhele nui ʻia ma Andhra Pradesh a me Orissa.
4. ka repubalika Czech
ʻO Czech Republic ka ʻāina me nā kumu waiwai flake graphite nui loa ma ʻEulopa. Aia nā waihona graphite flake ma ka moku'āina hema o Czech me kahi ʻano kalapona paʻa o 15%. ʻO nā waihona graphite flake ma ka ʻāina ʻo Moravia ka nui o ka microcrystalline ink me kahi maʻi kalapona paʻa ma kahi o 35%. 5. Mekikoka ʻO ka ʻohe graphite flake i loaʻa ma Mekiko he microcrystalline graphite i hoʻolaha nui ʻia ma nā mokuʻāina ʻo Sonora a me Oaxaca. ʻO ka hermosillo flake graphite microcrystalline ink i hoʻomohala ʻia he ʻono o 65% ~ 85%.
