Muaj ntau hom hmoov graphite hauv Suav teb, tab sis tam sim no, kev ntsuam xyuas cov khoom siv graphite ore hauv Suav teb yooj yim heev, tshwj xeeb tshaj yog kev ntsuam xyuas cov hmoov zoo, uas tsuas yog tsom mus rau cov qauv siv lead ua, cov pa roj carbon thiab sulfur thiab qhov loj me. Muaj qhov sib txawv loj hauv cov yam ntxwv thiab qhov zoo ntawm graphite ore thiab cov hmoov refined hauv cov chaw tsim graphite sib txawv, tab sis nws tsis yooj yim sua kom paub qhov txawv ntawm lawv tsuas yog los ntawm kev txheeb xyuas cov hmoov refined. Lub kaw lus faib tawm yooj yim tau coj txog qib siab ntawm kev sib xyaw ntawm cov khoom siv raw hauv qhov dej ntws ntawm graphite hauv ntau qhov chaw, uas tau zais nws cov txiaj ntsig siv tau. Tus kws kho hauv qab no ntawm Furuite Graphite qhia txog qhov kev thov sib txawv rau hmoov graphite hauv ntau qhov chaw:
Qhov xwm txheej no tau coj teeb meem tseem ceeb heev: ntawm ib sab tes, nws nyuaj heev thiab dig muag rau cov lag luam downstream ntawm graphite hmoov xaiv cov khoom siv graphite raw uas haum rau lawv cov khoom. Cov lag luam yuav tsum siv sijhawm ntau los txheeb xyuas thiab sim tsim cov khoom siv graphite raw nrog tib lub npe tab sis cov yam ntxwv sib txawv ntawm cov chaw tsim graphite loj hauv Suav teb, uas nkim sijhawm thiab lub zog ntau. Txawm hais tias nws siv sijhawm thiab kev rau siab los txiav txim siab cov khoom siv raw, qhov kev hloov pauv ntawm qee qhov tseem ceeb ntawm txhua pawg ntawm cov khoom siv raw tau ua rau cov lag luam hloov kho tas li qhov chaw thiab cov txheej txheem teeb tsa ntawm cov khoom siv raw. Ntawm qhov tod tes, cov lag luam upstream ntawm graphite hmoov tsis nkag siab txog qhov kev thov ntawm cov lag luam downstream rau cov khoom siv raw, uas ua rau muaj kev sib xyaw ua ke ntawm cov khoom.
