Garaafyada flake by metamorphism cadaadis sare, guud ahaan cawl buluug, cimilada huruud ah brown ama cawl caddaan, inta badan soo saaray in neiss, schist, crystalline limestone iyo skarn, macdanta symbionic waa ka sii adag, qaybta ugu weyn waa flake crystalline crystalline carbon, oo ay la socdaan graphite in the ore for flake crystalline ama qaabka caleen, madow ama bir cawl, inta badan ka dhaca feldspar, quartz ama diopside, qayb tremolite dhexeeya.Waxay leedahay habayn toosan oo cad, oo la socota jihada lakabka.Garaafyada Flake inta badan waa graphite exocrystalline dabiiciga ah, qaab-dhismeedka lamellar, qaabkeedu waa sida miisaanka kalluunka, nidaamka crystal hexagonal, gobolka crystal ayaa ka fiican, dhexroor cabbirka qaybtu waa 0.05 ~ 1.5μm, dhumucdiisuna waa 0.02 ~ 0.05 mm, jajabka ugu weyn wuxuu gaari karaa 4 ~ 5mm, kaarboonka graphite guud ahaan waa 2% ~ 5% ama 10% ~ 25%.
Meesha wax soo saarka ee graphite flake waxay inta badan ku taal Aasiya, Shiinaha iyo Sri Lanka, Yukreeniyaan Yurub, Mozambique, Madagascar, Tansaaniya iyo Koonfurta Ameerika Brazil iyo dalal kale, Mozambique, Tanzania, Madagascar iyo dalal kale oo hodan ah (super) graphite flake weyn, oo leh heer sare. qiimaha warshadaha.
"XOGTA BUUXAADA MACDANTA 2021" ee ay sii daysay US Geological Survey (USGS) waxay muujineysaa in dhamaadka 2020, kaydka garaafyada dabiiciga ah ee la xaqiijiyay ee adduunka waa 230 milyan oo tan, kuwaas oo Shiinaha, Brazil, Madagascar iyo Mozambique ay ku xisaabtameen in ka badan. in ka badan 84%.Waqtigan xaadirka ah, soosaarayaasha ugu muhiimsan ee garaafyada flake dabiiciga ah waa Shiinaha, Brazil iyo Hindiya.Laga soo bilaabo 2011 ilaa 2016, wax soo saarka caalamiga ah ee graphite flake dabiiciga ah ayaa weli xasilloon 1.1 ilaa 1.2 milyan t/a.Iyada oo ay saameeyeen dhowr arrimood, waxay hoos ugu dhacday 897,000 tan 2017;2018, waxay si tartiib tartiib ah kor ugu kacday 930,000 t;2019, sababtoo ah kororka sahayda garaafyada flake dabiiciga ah ee Mozambique, waxay ku soo noqotay 1.1 milyan t.Sannadka 2020-ka, wax-soo-saarka graphite-ka ee Shiinaha wuxuu noqonayaa 650,000 oo tan, taasoo ka dhigan qiyaastii 59% wax-soo-saarka guud ee adduunka, waana wax-soo-saarka ugu weyn adduunka;Mozambique flake graphite wax soo saarka oo ah 120,000 t, taasoo ka dhigan 11% wadarta wax soo saarka aduunka.
