I-Flake graphite ngoxinzelelo oluphezulu lwemetamorphism, ngokubanzi bluish grey, imozulu etyheli emdaka okanye engwevu emhlophe, eveliswa kakhulu kwi-neess, schist, crystalline limestone kunye ne-skarn, iiminerali zesymbionic zintsonkothe ngakumbi, eyona nxalenye iphambili yiflake crystalline crystalline carbon, ikhatshwa yigraphite intsimbi ekrwada yeflake yekristale okanye imilo yegqabi, emnyama okanye intsimbi engwevu, eyenzeka ikakhulu kwi-feldspar, iquartz okanye idiopside, amasuntswana e-tremolite phakathi.Inolungelelwaniso olucacileyo, oluhambelana nolwalathiso lomaleko.I-Flake graphite ubukhulu becala yigraphite yendalo ye-exocrystalline, i-lamellar structure, imilo yayo ifana nesikali sentlanzi, i-hexagonal crystal system, i-crystal state ingcono, ubukhulu besuntswana ubukhulu yi-0.05 ~ 1.5μm, ubukhulu beqhekeza yi-0.02 ~ 0.05 mm, i-flake enkulu inokufikelela kwi-4 ~ 5mm, umxholo wekhabhoni yegraphite ngokubanzi malunga ne-2% ~ 5% okanye i-10% ~ 25%.
Indawo yokuvelisa i-flake yegraphite ifumaneka ikakhulu e-Asia, eChina naseSri Lanka, e-Ukraine yaseYurophu, eMozambique, eMadagascar, eTanzania naseMzantsi Melika eBrazil kunye nakwamanye amazwe, eMozambique, eTanzania, eMadagascar kunye namanye amazwe acebileyo (super) amakhulu ixabiso lemveliso.
I-"MINERAL COMMODITY SUMMARIES 2021" ekhutshwe yi-US Geological Survey (USGS) ibonisa ukuba ekupheleni kuka-2020, iindawo zokugcina ze-graphite zendalo eziqinisekisiweyo emhlabeni ziyi-230 yezigidi zeetoni, apho i-China, i-Brazil, iMadagascar kunye ne-Mozambique ichaza ngakumbi. ngaphezu kwama-84%.Okwangoku, abavelisi abakhulu be-graphite yendalo ye-flake yi-China, i-Brazil kunye ne-Indiya.Ukususela kwi-2011 ukuya kwi-2016, imveliso yehlabathi jikelele ye-graphite ye-flake yendalo yahlala izinzile kwi-1.1 ukuya kwi-1.2 yezigidi ze-t / a.Ichatshazelwe luluhlu lwezinto, yehla ukuya kwiitoni ezingama-897,000 ngo-2017;Ngo-2018, yenyuka kancinci ukuya kwi-930,000 t;Ngo-2019, ngenxa yokwanda kokubonelelwa kwe-graphite yendalo ye-flake eMozambique, ibuyele kwi-1.1 yezigidi ze-t.Ngo-2020, imveliso yaseTshayina yeflake yegraphite iya kuba yi-650,000 yeetoni, ithatha malunga ne-59% yemveliso yehlabathi, kwaye ingumlimi omkhulu wehlabathi;Imveliso ye graphite yaseMozambique ye 120,000 t, ethatha i-11% yemveliso yehlabathi.
