He mea maka koʻikoʻi ka graphite unahi no ka hana ʻoihana. ʻO ka mea maka o ka graphite unahi he kumuwaiwai graphite. ʻO nā ʻano graphite e komo pū me ka graphite unahi maoli, ka graphite lepo, a me nā mea ʻē aʻe. He kumuwaiwai mineral ʻole ka graphite, i ʻeli ʻia mai ka ore graphite. I ka makahiki 2018, ua loaʻa kahi ore graphite nui loa ma ka moku ʻo Henan. Ua ʻimi ka First Geological Exploration Institute of Henan Bureau of Geology and Mineral Resources i kēia kumuwaiwai ore graphite ma Xichuan County, Henan Province, a ua hōʻea nā waihona kumuwaiwai o kahi wahi hana ore hoʻokahi i kahi kiʻekiʻe hou ma ka moku ʻo Henan, me 14.8155 miliona tons o nā kumuwaiwai graphite flake.
Wahi a ke kanaka kūpono e mālama ana i ka Geological Exploration Institute, ma o ke ana ʻana laulā, ua hoʻokaʻawale ʻia he 5 mau moena ore a me 6 mau kino ore ma ia wahi. ʻO ke ʻano ore graphite unahi he ʻano graphite plagioclase gneiss nui, a ʻo ke ʻano waiho ʻana he ʻano sedimentary metamorphic. E lilo kēia wahi i kahua eli graphite unahi koʻikoʻi ma Kina. Nui nā kumuwaiwai graphite flake i hoʻolaha ʻia ma ka ʻāina holoʻokoʻa, ma waena o ia mau waihona graphite crystalline nui i hoʻolaha nui ʻia ma Heilongjiang, Inner Mongolia, Shandong, Henan, Shaanxi, Sichuan, a pēlā aku, ʻo Heilongjiang lāua ʻo Shandong ka mea i hoʻopaʻa nui ʻia, ʻoiai ua hoʻolaha ʻia nā waihona graphite cryptocrystalline nui ma Hunan.
Aia ka graphite Furuite ma Qingdao, ka moku ʻo Shandong. Nui nā kumuwaiwai graphite flake kūlohelohe kūloko. Ma o ka hana ʻana i ka mīkini, hiki ke hana ʻia ka graphite kūlohelohe i graphite flake me nā nui ʻāpana like ʻole. Welina mai i nā mea kūʻai aku e kipa a hana pū!
