Sekureva kwemushumo weUS Geological Survey (2014), matura akaonekwa egirafiti yemhando ye natural flake graphite pasi rose imamiriyoni zana nemakumi matatu ematani, ayo Brazil ine matura emamiriyoni makumi mashanu nemasere ematani uye China ine matura emamiriyoni makumi mashanu nemashanu ematani, iri pakati penyika dzepamusoro. Nhasi, mupepeti weFuruite Graphite achakuudza nezvekupararira kwezviwanikwa zvegirafiti yemhando ye flake pasi rose:
Kubva pakupararira kwe flake graphite pasi rose, kunyangwe nyika zhinji dzakawana zvicherwa zve flake graphite, hapana akawanda madhaimondi ane chikero chakati chekushandiswa mumaindasitiri, anonyanya kuwanikwa muChina, Brazil, India, Czech Republic, Mexico nedzimwe nyika.
1. China
Zvichienderana nehuwandu hweMinistry of Land and Resources, kusvika pakupera kwegore ra2014, matura e crystalline graphite ore muChina aive matani mamiriyoni makumi maviri, uye matura ezviwanikwa akawanikwa aive matani angangoita mamiriyoni mazana maviri nemakumi maviri, ainyanya kuparadzirwa mumatunhu makumi maviri nenzvimbo dzinozvitonga dzakadai seHeilongjiang, Shandong, Inner Mongolia neSichuan, pakati pawo, Shandong neHeilongjiang ndiwo nzvimbo huru dzinogadzira. Matura e cryptocrystalline graphite muChina angangoita matani mamiriyoni mashanu, uye matura ezviwanikwa akaedzwa angangoita matani mamiriyoni makumi matatu nemashanu, ayo anonyanya kuparadzirwa mumatunhu mapfumbamwe nenzvimbo dzinozvitonga dzinosanganisira Hunan, Inner Mongolia neJilin. Pakati pawo, Chenzhou, Hunan pane huwandu hwe cryptocrystalline graphite.
2. Brazil
Zvichienderana nehuwandu hweUS Geological Survey, matura egrafiti muBrazil anosvika mamiriyoni makumi mashanu nemasere ematani, ayo matura egrafiti echisikigo anodarika mamiriyoni makumi matatu nematanhatu ematani. Matura egrafiti muBrazil anonyanya kupararira muMinas Gerais neBahia, uye matura egrafiti egrafiti akanakisa ari muMinas Gerais.
3. India
India ine matura egrafiti anokwana matani mamiriyoni gumi nerimwe uye zviwanikwa zvinokwana matani mamiriyoni zana nemakumi mashanu nemasere. Kune mabhandi matatu emigodhi yegrafiti, uye migodhi yegrafiti ine kukosha kwekusimudzira hupfumi inonyanya kuparadzirwa muAndhra Pradesh neOrissa.
4. Czech Republic
Czech Republic ndiyo nyika ine zviwanikwa zvakawanda zve flake graphite muEurope. Zvikamu zve flake graphite zvinonyanya kuwanika muSouth Czech Republic. Zvikamu zve flake graphite mudunhu reMoravia zvine kabhoni yakagadzika ye15% zvinonyanya kuve microcrystalline graphite, uye kabhoni yakagadzika inenge 35%.
5. Mekisiko
Migodhi yegrafiti yeflake yakawanikwa muMexico yese igrafiti yemicrocrystalline, inonyanya kuwanika muSonora neOaxaca. Grafiti yeHermosillo flake graphite yakagadzirwa ine giredhi re65% kusvika 85%.
