Cov txheej txheem ntau lawm ntawm cov graphite graphite mas suav nrog cov kauj ruam hauv qab no:
Cov khoom siv raw: cov ntaub ntawv raw ntawm cov zaub ntsuab graphite feem ntau los yog graphite schist, graphite gneiss, graphite-muaj cov schist thiab metamorphic shale. Cov ores no tuaj yeem faib ua crystalline graphite (flake graphite) thiab cryptocrystalline graphite (hauv ntiaj teb graphite) raws li lawv daim foos.
Tsuas thiab kev ua lag luam mineral: tso nyiaj ntxiv feem ntau yog mined hauv cov pits qhib, nrog tus nqi siab thiab tus nqi qis. Cov txheej txheem pob qij txha yog feem ntau suav nrog CRUSHING, GRADING THIAB FROTATION. Flotation yog ib qho kev sib piv los txhim kho cov kev coj dawb huv ntawm graphite, tab sis nws tuaj yeem nce nws cov kev coj ua rau 94-98%. Los tsim cov siab-huv claphite, tshuaj purification purification thiab lwm txoj hauv kev kuj yuav tsum muaj.
Purification: kev ua kom huv yog ib kauj ruam tseem ceeb hauv kev txhim kho cov kev huv huv ntawm graphite. Cov hau kev ua kom huv xws li cov pa thiab tshuaj purification. Flotation siv qhov sib txawv hauv cov khoom sib txawv ntawm cov zaub mov ntawm cov ntxhia rau kev sib cais, tab sis tsuas yog ua tiav ib qho kev coj dawb huv; Tshuaj lom neeg purification tshem tawm cov immurities los ntawm acid thiab alkali kho, acid thiab alkalitructor acid qauv, thiab lwm yam.
Kev Hloov Kho: Txhawm rau txhim kho kev ua tau zoo ntawm graphite, kev hloov kho qee zaum yuav tsum muaj. Kev hloov kho tau tuaj yeem hloov cov khoom saum npoo av thiab tshuaj lom neeg ntawm graphite lossis tshuaj lom neeg kom tau raws li kev xav tau ntawm cov ntawv thov.
Kev sib xyaw thiab carbonancy: thaum lub sijhawm ua haujlwm ntau ntxiv yog sib xyaw nrog lwm cov ntaub ntawv thiab tom qab ntawd carbonized kom tau txais cov khoom siv lub cev thiab tshuaj lom neeg xav tau.
Daim ntawv thov cov chaw ntawm ntuj Graphite: ntuj graphite yog dav siv nyob rau hauv cov roj teeb, tshuab ua yeeb yam, kev lag luam tshiab, kev lag luam kev ua tub rog, kev lag luam kev ua tub rog, kev lag luam nuclear. Nyob rau hauv lub khw thov kev lag luam, Refractory cov ntaub ntawv, cov ntaub ntawv thiab cov ntaub ntawv sealing yog cov chaw thov tseem ceeb
