Flake graphite yog ib qho khoom siv tsis tshua muaj uas tsis rov ua dua tshiab, uas siv dav hauv kev lag luam niaj hnub no thiab yog ib qho khoom siv tseem ceeb. European Union tau teev graphene, cov khoom tiav ntawm kev ua graphite, ua ib qho project tshiab hauv kev siv tshuab yav tom ntej, thiab teev graphite ua ib qho ntawm 14 hom "lub neej thiab kev tuag" cov khoom siv tsis tshua muaj. Tebchaws Meskas teev cov khoom siv graphite flake ua cov khoom siv tseem ceeb rau kev lag luam high-tech. Tuam Tshoj cov khoom siv graphite suav txog 70% ntawm lub ntiaj teb, thiab nws yog qhov chaw khaws cia graphite loj tshaj plaws thiab xa tawm hauv ntiaj teb. Txawm li cas los xij, muaj ntau yam teeb meem hauv cov txheej txheem tsim khoom, xws li kev pov tseg hauv kev khawb av, kev siv cov peev txheej tsawg thiab kev puas tsuaj rau ib puag ncig loj heev. Qhov tsis txaus ntawm cov peev txheej thiab tus nqi sab nraud ntawm ib puag ncig tsis qhia txog tus nqi tiag tiag. Cov teeb meem sib koom ua ke ntawm Furuite graphite editors feem ntau pom tseeb hauv cov hauv qab no:
Ua ntej, cov se peev txheej yuav tsum tau hloov kho sai sai. Tus nqi se qis: Tuam Tshoj cov se peev txheej graphite tam sim no yog 3 yuan ib tuj, uas sib dua thiab tsis qhia txog qhov tsis txaus ntawm cov peev txheej thiab tus nqi sab nraud ntawm ib puag ncig. Piv nrog cov av tsis tshua muaj uas muaj qhov tsis txaus thiab qhov tseem ceeb zoo sib xws, tom qab kev hloov pauv ntawm cov se peev txheej av tsis tshua muaj, tsis yog tsuas yog cov khoom se tau teev tseg sib cais, tab sis kuj tseem nce tus nqi se ntau dua 10 npaug. Piv txwv li, tus nqi se peev txheej ntawm flake graphite qis. Tus nqi se ib leeg: cov cai ib ntus tam sim no ntawm cov se peev txheej muaj tus nqi se ib leeg rau graphite ore, uas tsis faib raws li qib zoo thiab hom graphite, thiab tsis tuaj yeem qhia txog kev ua haujlwm ntawm cov se peev txheej hauv kev tswj hwm cov nyiaj tau los sib txawv. Nws tsis yog kev tshawb fawb los xam los ntawm qhov ntim muag khoom: nws yog xam los ntawm qhov ntim muag khoom, tsis yog los ntawm qhov tseeb ntawm cov zaub mov mined, tsis xav txog kev them nyiaj rau kev puas tsuaj rau ib puag ncig, kev txhim kho cov peev txheej, cov nqi tsim kho thiab kev siv cov peev txheej.
Qhov thib ob, kev xa khoom tawm sai dhau lawm. Tuam Tshoj yog lub ntiaj teb tus tsim cov flake graphite ntuj loj tshaj plaws thiab yeej ib txwm yog tus xa khoom loj tshaj plaws ntawm cov khoom graphite ntuj. Hauv kev sib piv rau Tuam Tshoj txoj kev siv cov khoom siv flake graphite ntau dhau, cov teb chaws tsim kho, uas yog cov thawj coj hauv kev siv tshuab ntawm cov khoom siv graphite tob, siv txoj kev "yuav es tsis txhob khawb av" rau cov graphite ntuj thiab thaiv cov thev naus laus zis. Raws li kev lag luam graphite loj tshaj plaws hauv Tuam Tshoj, Nyiv Pooj cov khoom xa tuaj suav txog 32.6% ntawm Tuam Tshoj tag nrho cov khoom xa tawm, thiab ib feem ntawm cov graphite ore xa tuaj poob rau hauv hiav txwv; Kaus Lim Qab Teb, ntawm qhov tod tes, kaw nws cov graphite mines thiab xa tawm ntau yam khoom ntawm tus nqi qis; Tebchaws Meskas cov khoom xa tuaj txhua xyoo suav txog li 10.5% ntawm Tuam Tshoj tag nrho cov khoom xa tawm, thiab nws cov khoom siv graphite raug tiv thaiv los ntawm txoj cai lij choj.
Qhov thib peb, kev ua cov txheej txheem no dav dhau lawm. Cov khoom ntawm graphite muaj feem cuam tshuam nrog qhov loj ntawm nws cov nplai. Cov nplai sib txawv ntawm cov flake graphite muaj kev siv sib txawv, cov txheej txheem ua thiab cov teb thov. Tam sim no, tsis muaj kev tshawb fawb txog cov thev naus laus zis graphite ore nrog cov yam ntxwv sib txawv hauv Suav teb, thiab kev faib tawm ntawm cov peev txheej graphite nrog cov nplai sib txawv tsis tau paub meej, thiab tsis muaj txoj kev ua tiav tob sib xws. Tus nqi rov qab ntawm graphite beneficiation qis, thiab cov txiaj ntsig ntawm cov flake graphite loj yog qis. Cov yam ntxwv ntawm cov peev txheej tsis meej, thiab txoj kev ua tiav yog ib qho. Yog li ntawd, cov nplai loj graphite tsis tuaj yeem tiv thaiv tau zoo thiab cov nplai me me graphite tsis tuaj yeem siv tau zoo thaum lub sijhawm ua tiav, ua rau muaj kev pov tseg loj ntawm cov peev txheej tseem ceeb.
Qhov thib plaub, qhov sib txawv ntawm tus nqi ntawm kev xa khoom tuaj thiab xa tawm yog qhov zoo kawg nkaus. Feem ntau ntawm cov khoom lag luam graphite ntuj tsim hauv Suav teb yog cov khoom lag luam tseem ceeb tshaj plaws, thiab kev tshawb fawb thiab kev txhim kho thiab kev tsim cov khoom muaj nqis ntxiv yog qhov tsis txaus. Piv txwv li, cov teb chaws txawv teb chaws ua tus thawj coj hauv graphite ntshiab nrog lawv cov txiaj ntsig thev naus laus zis, thiab thaiv peb lub teb chaws hauv cov khoom lag luam graphite siab. Tam sim no, Tuam Tshoj cov thev naus laus zis graphite ntshiab tsis tshua muaj peev xwm ncav cuag qhov huv ntawm 99.95%, thiab qhov huv ntawm 99.99% lossis ntau dua tsuas yog nyob ntawm kev xa khoom tuaj xwb. Xyoo 2011, tus nqi nruab nrab ntawm graphite ntuj hauv Suav teb yog li 4,000 yuan / ton, thaum tus nqi ntau dua 99.99% xa tawm los ntawm graphite ntshiab siab tshaj 200,000 yuan / ton, thiab qhov sib txawv ntawm tus nqi yog qhov zoo kawg nkaus.
