Igrafite eyandisiweyo iveliswa ziinkqubo ezimbini: imichiza kunye ne-electrochemical. Ezi nkqubo zimbini zahlukile ukongeza kwinkqubo ye-oxidation, deacidification, ukuhlanjwa kwamanzi, ukomisa, ukomisa kunye nezinye iinkqubo ziyafana. Umgangatho weemveliso uninzi lwabenzi abasebenzisa indlela yemichiza inokufikelela kwisalathiso esichazwe kwi-GB10688-89 "eyandisiweyo yegrafite" esemgangathweni, kwaye ihlangabezane neemfuno ezibonakalayo zokuveliswa kwephepha le-graphite eliguquguqukayo kunye nemigangatho yokubonelela ngokuthumela ngaphandle.
Kodwa ukuveliswa kweemfuno ezizodwa zexabiso eliphantsi (≤10%), umxholo wesalfure ophantsi (≤2%) yeemveliso zinzima, inkqubo yemveliso ayidluli. Ukomeleza ulawulo lobuchwephesha, ukufunda inkqubo yokubala ngononophelo, ukuqonda ubudlelwane phakathi kweenkqubo kunye nokusebenza kwemveliso, kunye nokuvelisa umgangatho ozinzileyo wegraphite eyandisiweyo zizitshixo zokuphucula umgangatho weemveliso ezilandelayo. Isishwankathelo se-Qingdao Furuite Graphite: indlela ye-electrochemical ngaphandle kwezinye i-oxidants, i-flake grafite yendalo kunye ne-anode encedisayo ngokudibeneyo zenza igumbi le-anode lifakwe kwi-sulfuric acid electrolyte egudileyo, ngoku yangoku okanye ukubetha kwangoku, i-oxidation emva kwexesha elithile ukuyikhupha, emva kokuhlamba nokoma yigrafite ebonakalayo. Olona phawu lukhulu lwale ndlela kukuba inqanaba lokusabela kwigrafu kunye nesalathiso sokusebenza kwemveliso sinokulawulwa ngokulungelelanisa iiparameter zombane kunye nexesha lokuphendula, ngongcoliseko oluncinci, iindleko eziphantsi, umgangatho ozinzileyo kunye nokusebenza ngokugqwesileyo. Kungxamisekile ukusombulula ingxaki yokuxuba, ukuphucula ukusebenza ngokukuko kunye nokunciphisa ukusetyenziswa kwamandla kwinkqubo yokubala.
Emva kokuchithwa kwezi nkqubo zimbini zingentla, umlinganiso wobunzima be-asidi ye-acid yokumanzi kunye ne-adsorption ye-graphite interlamellar compounds isekhona malunga ne-1: 1, ukusetyenziswa kwe-arhente yokuthintela inkulu, kwaye ukusetyenziswa kwamanzi okuhlamba kunye nokukhutshwa kwelindle kuphezulu. Kwaye uninzi lwabavelisi abalusombululanga ingxaki yokucocwa kwamanzi amdaka, kwimeko yokukhutshelwa kwendalo, ungcoliseko lwendalo luluqilima, luya kuthintela uphuhliso lweshishini.
