Flake graphite ndi high pressure metamorphism, kawirikawiri bluish imvi, weathered chikasu bulauni kapena imvi woyera, makamaka opangidwa neiss, schist, crystalline laimu ndi skarn, symbionic mchere ndi zovuta, chigawo chachikulu ndi flake crystalline crystalline carbon, limodzi ndi graphite mu miyala ya crystalline flake kapena mawonekedwe a tsamba, yakuda kapena chitsulo imvi, makamaka yopezeka mu feldspar, quartz kapena diopside, tremolite particles pakati.Lili ndi ndondomeko yowonekera bwino, yogwirizana ndi malangizo a wosanjikiza.Flake graphite ndi zambiri zachilengedwe exocrystalline graphite, kapangidwe lamellar, mawonekedwe ake ali ngati sikelo nsomba, hexagonal galasi dongosolo, kristalo boma ndi bwino, tinthu kukula m'mimba mwake ndi 0.05 ~ 1.5μm, makulidwe a chidutswa ndi 0.02 ~ 0.05 mamilimita, flake lalikulu akhoza kufika 4 ~ 5mm, mpweya zili graphite zambiri za 2% ~ 5% kapena 10% ~ 25%.
Kupanga malo a flake graphite makamaka ili mu Asia, China ndi Sri Lanka, Ukraine ku Ulaya, Mozambique, Madagascar, Tanzania ndi South America a Brazil ndi mayiko ena, Mozambique, Tanzania, Madagascar ndi mayiko olemera (wapamwamba) lalikulu flake graphite, ndi mkulu mtengo wamakampani.
"MINERAL COMMODITY SUMMARIES 2021" yotulutsidwa ndi US Geological Survey (USGS) ikuwonetsa kuti pofika kumapeto kwa 2020, malo otetezedwa achilengedwe padziko lonse lapansi ndi matani 230 miliyoni, pomwe China, Brazil, Madagascar ndi Mozambique amawerengera zambiri. kuposa 84%.Pakali pano, omwe amapanga ma graphite achilengedwe ndi China, Brazil ndi India.Kuyambira 2011 mpaka 2016, kupanga padziko lonse lapansi kwachilengedwe kwa graphite kunakhalabe kokhazikika pa 1.1 mpaka 1.2 miliyoni t/a.Chifukwa cha zinthu zingapo, idatsika mpaka matani 897,000 mu 2017;Mu 2018, idakwera pang'onopang'ono mpaka 930,000 t;Mu 2019, chifukwa cha kuchuluka kwa ma graphite achilengedwe ku Mozambique, idabwerera ku 1.1 miliyoni t.Mu 2020, China flake kupanga graphite adzakhala matani 650,000, mlandu pafupifupi 59% ya okwana linanena bungwe dziko, ndipo ndi sewerolo wamkulu padziko lonse;Ku Mozambique kupangidwa kwa ma graphite okwana 120,000 t, zomwe zimapangitsa 11% yazotulutsa zonse padziko lapansi.
