Flake graphite ine high pressure metamorphism, kazhinji bluish grey, yakasvibirira yero yebrown kana greyish chena, inogadzirwa mu neiss, schist, crystalline limestone uye skarn, zvicherwa zvesymbionic zvakanyanya kuomarara, chikamu chikuru ndeye flake crystalline crystalline kabhoni, inoperekedzwa negraphite mu ore yecrystalline flake kana chimiro cheshizha, dema kana simbi grey, inowanzoitika mufeldspar, quartz kana diopside, tremolite zvidimbu pakati.Iine hurongwa huri pachena hwehutungamiri, hunopindirana nehutungamiri hwehupamhi.Flake graphite kazhinji yakasikwa exocrystalline graphite, chimiro chelamellar, chimiro chayo chakafanana nechikero chehove, hexagonal crystal system, crystal state iri nani, chidimbu chekukura kwe 0.05 ~ 1.5μm, ukobvu hwechidimbu i 0.02 ~ 0.05 mm, iyo yakakura flake inogona kusvika 4 ~ 5mm, iyo kabhoni yemukati yegraphite inowanzoita 2% ~ 5% kana 10% ~ 25%.
Nzvimbo yekugadzira yeflake graphite inonyanya kuwanikwa muAsia, China neSri Lanka, Ukraine yeEurope, Mozambique, Madagascar, Tanzania neSouth America yeBrazil nedzimwe nyika, Mozambique, Tanzania, Madagascar nedzimwe nyika dzakapfuma (super) hombe flake graphite, ine yakakwirira. indasitiri kukosha.
Iyo "MINERAL COMMODITY SUMMARIES 2021" yakaburitswa neUS Geological Survey (USGS) inoratidza kuti panozopera gore ra2020, nzvimbo dzinochengeterwa girafu dzepasi rose dzinosvika mazana maviri nemakumi matatu emamiriyoni ematani, ayo China, Brazil, Madagascar neMozambique anoverengera zvimwe. kupfuura 84%.Parizvino, vagadziri vakuru veakasikwa flake graphite iChina, Brazil neIndia.Kubva 2011 kusvika 2016, kugadzirwa kwepasi rose kwechisikigo flake graphite kwakaramba kwakagadzikana pa 1.1 kusvika 1.2 mamiriyoni t / a.Yakabatwa nenhevedzano yezvinhu, yakaderera kusvika ku897,000 matani muna 2017;Muna 2018, zvishoma nezvishoma yakasimuka kusvika ku930,000 t;Muna 2019, nekuda kwekuwedzera kwekupihwa kwechisikigo flake graphite muMozambique, yakadzokera kune 1.1 miriyoni t.Muna 2020, China flake graphite kugadzirwa achava 650,000 matani, achiverenga pamusoro 59% yepasi rose goho, uye ndiye mugadziri mukuru pasi rose;Mozambique kugadzirwa kwe graphite ye 120,000 t, inoverengera 11% yehuwandu hwepasi rose.
