Ma ka ʻoihana, ua hoʻokaʻawale ʻia ka graphite kūlohelohe i ka graphite crystalline a me ka graphite cryptocrystalline e like me ke ʻano aniani. ʻOi aku ka maikaʻi o ka crystallized crystalline graphite, a ʻo ke anawaena o ka pā aniani he> 1 μm, ka mea i hana nui ʻia e kahi aniani a i ʻole ke aniani flaky. ʻO ka graphite crystalline kekahi o nā minerala hoʻolālā 24 ma ka ʻāina. Ua helu ʻia ka ʻimi a me ka hoʻomohala ʻana o ka graphite ma ka National Mineral Resources Planning (2016-2020) no ka manawa mua. ʻO ke koʻikoʻi o ka graphite crystalline e alakaʻi ʻia e nā manaʻo e like me nā kaʻa ikehu hou a me ka graphene. He piʻi nui.
Wahi a ka US Geological Survey (USGS), e like me ka hopena o 2017, ʻo 270 miliona mau tons ka mālama ʻana i ka graphite o ka honua, i hoʻolaha nui ʻia ma Turkey, Kina a me Brazil, kahi i hoʻomalu ʻia ai ʻo Kina e ka crystalline graphite a ʻo Turkey ka cryptocrystalline graphite. He haʻahaʻa ka waiwai o ka cryptocrystalline graphite a me ka palena o ka hoʻomohala ʻana a me ka hoʻohana ʻana, no laila e hoʻoholo ka crystalline graphite i ke ʻano graphite honua.
Wahi a ka Chinese Academy of Sciences, ʻoi aku ka nui o ka graphite crystalline o Kina ma mua o 70% o ka nui o ka honua. Ma waena o lākou, hiki i nā kumu waiwai graphite crystalline o Heilongjiang ke helu no 60% o Kina a ʻoi aku ma mua o 40% o ka honua, kahi mea hoʻoholo. ʻO Kina nā mea hana nui o ka honua i ka crystalline graphite, a ukali ʻia e India a me Brazil.
Māhele waiwai
ʻO ke kumu honua o nā waihona graphite crystalline ma nā wahi like ʻole o Kina
Nā hiʻohiʻona nui o nā waihona graphite crystalline nui ma Kina a me ka hua o nā unahi nui (> 0.15mm)
ʻĀpana Heilongjiang
ʻO ka mokuʻo Heilongjiang kahi mahele nui o ka graphite, a maikaʻi loa ia ma Hegang a me Jixi. ʻO kona ʻāpana hikina ka waihona waiwai nui loa o ka graphite crystalline ma ka ʻāina, me nā waihona graphite kaulana nui a me ka super-nui e like me Jixi Liumao, Luobei Yunshan a me Muling Guangyi. Ua loaʻa nā mines graphite ma 7 o nā kūlanakauhale he 13 ma ka panalāʻau. ʻO nā waihona waiwai i manaʻo ʻia he 400 miliona mau tons, a ʻo nā kumuwaiwai hiki ke loaʻa ma kahi o 1 billion tons. Loaʻa iā Mudanjiang a me Shuangyashan nā ʻike nui, akā ʻike ʻia ka maikaʻi o nā kumuwaiwai. ʻO ka graphite kiʻekiʻe ka mea i hoʻomalu ʻia e Hegang a me Jixi. Ua manaʻo ʻia e hiki ke loaʻa i nā waihona graphite i ka panalāʻau i ka 1-150 miliona tons (ka nui o ka mineral).
Māhele Kūʻokoʻa ʻo Mongolia
ʻO ka mālama ʻana o ka crystalline graphite ma Inner Mongolia ka lua wale nō iā Heilongjiang, ka mea nui i kahele ʻia ma Inner Mongolia, Xinghe, Alashan a me Baotou.
ʻO ka papa kalapona paʻa o ka graphite ore ma Xinghe wahi maʻamau ma waena o 3% a me 5%. ʻO ka pālākiō o ka pālākiō he> 0.3mm, helu no kahi o 30%, a ʻo ka pālākiō o ka pālākiō he> 0.15mm, hiki ke piʻi aku ma mua o 55%. Ma kahi o Alashan, e lawe ana i ka waihona graphite Chahanmuhulu ma ke ʻano he laʻana, ʻo ka awelika o ka pae o ke kalapona i hoʻopaʻa ʻia ma kahi o 5.45%, a ʻo ka hapa nui o nā unahi graphite he> 0.15 mm. ʻO ka mine graphite ma Chaganwendu wahi o Damao Banner ma Baotou he awelika kalapona paʻa o 5.61% a me ke anawaena unahi o ka nui <0.15mm.
ʻĀpana ʻo Sichuan
Hāʻawi nui ʻia nā kumu waiwai graphite crystalline ma Sichuan Province ma Panzhihua, Bazhong a me Aba Prefecture. He 6.21% ka helu awelika o ke kalapona paʻa i loko o ka graphite ore ma Panzhihua a me Zhongba. He mau unahi liʻiliʻi ka ʻeleʻele, a ʻaʻole ʻoi aku ka nui o ka unahi ma mua o 0.15mm. ʻO ka pae kalapona paʻa o ka crystalline graphite ore ma Nanjiang wahi o Bazhong City he 5% a 7%, ʻo ka mea kiʻekiʻe loa he 13%, a ʻo ka hapa nui o nā unahi graphite he> 0.15 mm. ʻO ka papa kalapona paʻa o ka graphite ore ma Aba Prefecture he 5% ~ 10%, a ʻo ka hapa nui o nā unahi graphite he <0.15mm.
Panalaau o Shanxi
Ua loaʻa i ka ʻāina ʻo Shanxi he 8 mau kumu o ka mālama ʻana i ka crystalline i ʻike ʻia o nā mineral graphite crystalline, i hoʻolaha nui ʻia ma ka ʻāina ʻo Datong. ʻO ka awelika helu o ke kalapona paʻa i loko o ka waihona ka hapa nui ma waena o 3% a me 4%, a ʻo ka hapa nui o nā unahi graphite he> 0.15 mm. Hōʻike ka hōʻike ʻana i ka ʻaʻahu ʻaʻahu e pili ana i ka 38% ka nui o ka hua nui, e like me ka mine graphite ma Qili Village, Xinrong District, Datong.
ʻĀpana ʻo Shandong
Hāʻawi nui ʻia nā kumu waiwai graphite crystalline ma Shandong Province ma Laixi, Pingdu a me Laiyang. ʻO ka awelika o ke kalapona paʻa ma ke komohana hema o Lai ma kahi o 5.18%, a ʻo ke anawaena o ka hapa nui o nā pepa graphite ma waena o 0.1 a me 0.4 mm. ʻO ka awelika helu o ke kalapona paʻa ma Liugezhuang graphite mine ma Pingdu City ma kahi o 3.34%, a ʻo ka nui o ke anawaena he <0.5mm. Loaʻa iā Pingdu Yanxin Graphite Mine ka awelika o ke kalapona paʻa o 3.5%, a ʻo ka pālākiō o ka unahi he> 0.30mm, helu no 8% a 12%. I ka hōʻuluʻulu manaʻo, ʻo ka awelika o nā kalapona paʻa i nā mines graphite ma Shandong ma waena o 3% a me 5%, a ʻo ka hapa o nā unahi> 0.15 mm he 40% a 60%.
kūlana hana
ʻO nā waihona graphite o Kina he mau māka ʻoihana maikaʻi, maikaʻi ia no ka mining, a ʻaʻole i emi iho ka graphite crystalline ma mua o 3%. I nā makahiki he 10 i hala iho nei, aia ma waena o 60,000 a me 800,000 tons ka huahana graphite makahiki o Kina, kahi o 80% o ka hana graphite crystalline.
ʻOi aku ma mua o hoʻokahi kaukani ʻoihana hana graphite ma Kina, a ʻo nā huahana nā huahana mineral graphite e like me ka medium and high carbon graphite, kiʻekiʻe maʻemaʻe graphite a me ka graphite pauda maikaʻi, a me nā mea graphite hoʻonui a me nā mea kalapona. ʻO ke ʻano o ka ʻoihana ka mea nui o ka mokuʻāina, ka mea i māhele nui ʻia ma Shandong, Inner Mongolia, Hubei, Heilongjiang, Zhejiang a me nā wahi ʻē aʻe. He kahua paʻa ko ka ʻoihana mining graphite mokuʻāina a me nā pōmaikaʻi nui i ka ʻenehana a me nā kumuwaiwai.
Hoʻohana nui ʻia ka Graphite i ke kila, metallurgy, foundry, mechanical equipment, chemical industry a me nā māla ʻē aʻe ma muli o kāna mau waiwai maikaʻi. Me ka holomua o ka ʻepekema a me ka ʻenehana, e ʻimi mālie ʻia ka noi ʻana o nā mea graphite hou i nā ʻoihana ʻenehana kiʻekiʻe e like me ka ikehu hou, ʻoihana nuklea, ʻike uila, aerospace a me ka pale ʻana, a ua manaʻo ʻia he kumu waiwai kūpono e pono ai. ka hoʻomohala ʻana i nā ʻoihana e kū nei. I kēia manawa, hoʻohana nui ʻia nā huahana graphite o Kina i nā mea refractory, castings, sila, graphite kūikawā a me nā māla ʻē aʻe, i waena o nā mea refractory a me nā castings i hoʻohana nui ʻia.
Me ka hoʻomau mau ʻana o ka ʻoihana ikehu hou, e piʻi mau ka noi no ka graphite i ka wā e hiki mai ana.
ʻO ka wānana noi graphite o Kina ma 2020
