I-Flake graphite iyiminerali eyivelakancane engavuseleleki, esetshenziswa kakhulu embonini yesimanje futhi iyisisetshenziswa esibalulekile samasu. I-European Union yabala i-graphene, umkhiqizo oqediwe wokucutshungulwa kwe-graphite, njengephrojekthi entsha yobuchwepheshe obuphambili esikhathini esizayo, futhi yabala i-graphite njengolunye lwezinhlobo ezingu-14 zemithombo yezimbiwa eyivelakancane “yokuphila nokufa”. I-United States ibala izinsiza ze-flake graphite njengezimbiwa ezibalulekile zokusetshenziswa kwezimboni zobuchwepheshe obuphezulu. Izinqolobane ze-graphite zaseShayina zenza amaphesenti angama-70 omhlaba, futhi iyindawo yokulondoloza i-graphite enkulu kunazo zonke futhi ethumela ngaphandle emhlabeni. Kodwa-ke, kunezinkinga eziningi ohlelweni lokukhiqiza, njengemfucuza yezimayini, izinga eliphansi lokusebenzisa izinsiza kanye nokulimala okukhulu kwemvelo. Ukushoda kwezinsiza kanye nezindleko zangaphandle zendawo ezungezile akubonisi inani langempela. Izinkinga ezilandelayo zokwabelana zabahleli be-Furuite graphite zibonakaliswa ikakhulukazi kulezi zici ezilandelayo:
Okokuqala, intela yezinsiza idinga ukulungiswa ngokushesha. Izinga lentela eliphansi: Intela yensiza ye-graphite yamanje yase-China ingu-3 yuan ngethani, elilula kakhulu futhi elingabonisi ukushoda kwezinsiza kanye nezindleko zangaphandle zemvelo. Uma kuqhathaniswa nemihlaba engavamile enokuntuleka kwamaminerali afanayo kanye nokubaluleka, ngemva kokuguqulwa kwentela yezinsiza zomhlaba ezingavamile, akuzona kuphela izinto zentela ezibalwe ngokwehlukana, kodwa futhi izinga lentela liphakanyiswa izikhathi ezingaphezu kwe-10. Uma kuqhathaniswa, izinga lentela yensiza ye-flake graphite liphansi. Izinga lentela elilodwa: imithethonqubo yamanje yesikhashana yentela yensiza inenani lentela elilodwa le-graphite ore, elingahlukaniswa ngokwezinga lekhwalithi kanye nohlobo lwegraphite, futhi ayikwazi ukubonisa umsebenzi wentela yensiza ekulawuleni imali engenayo ehlukile. Akuyona isayensi ukubala ngevolumu yokuthengisa: kubalwa ngevolumu yokuthengisa, hhayi inani langempela lamaminerali ambiwayo, ngaphandle kokucabangela isinxephezelo sokulimala kwemvelo, ukuthuthukiswa okunengqondo kwezinsiza, izindleko zokuthuthukiswa kanye nokuphelelwa amandla kwezinsiza.
Okwesibili, ukuthunyelwa kuyashesha kakhulu. I-China ingumkhiqizi omkhulu kunayo yonke emhlabeni we-natural flake graphite futhi ibilokhu ingumthengisi omkhulu kunabo bonke wemikhiqizo yemvelo ye-graphite. Ngokuphambene kakhulu nokuxhashazwa ngokweqile kwemithombo ye-flake graphite yaseChina, amazwe athuthukile, ahamba phambili kubuchwepheshe bemikhiqizo yokucubungula i-graphite deep, asebenzisa isu "lokuthenga esikhundleni sokumba" i-graphite yemvelo futhi avimbe ubuchwepheshe. Njengemakethe ye-graphite enkulu kunazo zonke e-China, ukuthengwa kwe-Japan kwamanye amazwe kubalelwa ku-32.6% wesamba sempahla ethunyelwa ngaphandle yase-China, futhi ingxenye ye-graphite ore engenisiwe izika phansi olwandle; Ngakolunye uhlangothi, iNingizimu Korea, yavala izimayini zayo ze-graphite futhi yangenisa inqwaba yemikhiqizo ngamanani aphansi; Umthamo wonyaka wokungenisa wase-United States uhlanganisa cishe u-10.5% wesamba sesamba esithunyelwa ngaphandle saseShayina, futhi izinsiza zayo ze-graphite zivikelwe ngumthetho.
Okwesithathu, ukucutshungulwa kukhulu kakhulu. Izici ze-graphite zihlobene eduze nobukhulu bezikali zayo. Osayizi abahlukene be-flake graphite banokusetshenziswa okuhlukile, izindlela zokucubungula kanye nezinkambu zokufaka isicelo. Njengamanje, kukhona ukuntuleka kocwaningo ngobuchwepheshe be-graphite ore obunezici ezihlukene e-China, futhi ukusatshalaliswa kwezinsiza ze-graphite ngezikali ezihlukene akukaqinisekiswa, futhi ayikho indlela yokucubungula ejulile ehambisanayo. Izinga lokutholwa kwe-graphite beneficiation liphansi, futhi isivuno se-flake graphite enkulu siphansi. Izici zensiza azicacile, futhi indlela yokucubungula iyodwa. Ngenxa yalokho, i-graphite ye-flake enkulu ayikwazi ukuvikelwa ngokuphumelelayo futhi i-graphite ye-flake encane ayikwazi ukusetshenziswa ngokuphumelelayo ngesikhathi sokucutshungulwa, okuholela ekumosheni okukhulu kwezinsiza ezibalulekile zamasu.
Okwesine, umehluko wentengo phakathi kokungenisa nokuthekelisa uyamangalisa. Iningi lemikhiqizo yemvelo ye-graphite ye-flake ekhiqizwa e-China iyimikhiqizo ephambili kakhulu ecutshungulwayo, futhi ucwaningo nokuthuthukiswa nokukhiqizwa kwemikhiqizo enenani eliphakeme ngokusobala ayashoda. Thatha i-graphite yokuhlanzeka okuphezulu njengesibonelo, amazwe angaphandle ahola ekuhlanzekeni okuphezulu kwe-graphite ngezinzuzo zabo zobuchwepheshe, futhi avimbele izwe lethu emikhiqizweni ye-graphite high-tech. Njengamanje, ubuchwepheshe be-graphite obuphezulu baseShayina abukwazi ukufinyelela ubumsulwa obungama-99.95%, kanti ubumsulwa obungama-99.99% noma ngaphezulu bungancika ngokuphelele ekuthengisweni kwamanye amazwe. Ngo-2011, intengo ejwayelekile ye-natural flake graphite e-China yayicishe ibe yi-4,000 yuan/ton, kuyilapho intengo engaphezu kuka-99.99% engenisiwe isuka ku-graphite ehlanzekile idlula i-200,000 yuan/ton, futhi umehluko wentengo wawumangalisa.
