He mea waiwai nui ka graphite unahi no ka hana ʻoihana. ʻO ka waiwai maka o ka graphite unahi he kumu graphite. ʻO nā ʻano graphite ka graphite unahi maoli, ka graphite honua, a me nā mea ʻē aʻe. I ka makahiki 2018, ua loaʻa kahi oka 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 kumu waiwai graphite ore ma Xichuan County, Henan Province, a ua hiki i kahi kiʻekiʻe o ka ʻāina hana ʻai hoʻokahi i kahi kiʻekiʻe ma ka ʻāina ʻo Henan, me 14.8155 miliona mau tona o ka flake graphite. waiwai.
Wahi a ka mea kūpono e mālama ana i ka Geological Exploration Institute, ma o ka ʻimi noiʻi nui, ua hoʻokaʻawale ʻia nā moena ʻeleʻele 5 a me 6 mau kino oka ma ia wahi. ʻO ke ʻano o ka graphite ore ka nui o ka graphite plagioclase gneiss type, a ʻo ke ʻano waihona he ʻano metamorphic sedimentary. E lilo ana kēia wahi i kumu eli graphite nui ma Kina. Nui nā kumu waiwai flake graphite i hoʻolaha ʻia ma ka ʻāina holoʻokoʻa, ma waena o nā waihona graphite crystalline nui i hoʻolaha nui ʻia ma Heilongjiang, Inner Mongolia, Shandong, Henan, Shaanxi, Sichuan, etc. ua puunaueia ma Hunan.
Aia ka Furuite graphite ma Qingdao, Shandong Province. He waiwai nā kumu waiwai graphite flake maoli. Ma o ka hana ʻana i ka mīkini, hiki ke hana ʻia ka graphite kūlohelohe i flake graphite me nā ʻāpana like ʻole. Welina mai nā mea kūʻai aku e kipa a hui pū!
