Ma ke ʻano ʻoihana, ua hoʻokaʻawale ʻia ka graphite kūlohelohe i loko o ka graphite crystalline a me ka graphite cryptocrystalline e like me ke ʻano o ke kristal. ʻOi aku ka maikaʻi o ka crystallized ʻana o ka graphite crystalline, a ʻo ke anawaena o ka papa kristal he >1 μm, ka mea i hana nui ʻia e kahi kristal hoʻokahi a i ʻole kahi kristal flaky. ʻO ka graphite crystalline kekahi o nā minelala koʻikoʻi 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), i ka hopena o 2017, ʻo ka nui o nā waihona graphite o ka honua ma kahi o 270 miliona tone, i hoʻolaha nui ʻia ma Turkey, Kina a me Brazil, kahi i noho aliʻi ʻia e ka graphite crystalline ma Kina a ʻo Turkey ka graphite cryptocrystalline. He haʻahaʻa ka waiwai o ka graphite cryptocrystalline a he palena ka manaʻolana no ka hoʻomohala a me ka hoʻohana ʻana, no laila ke hoʻoholo nei ka graphite crystalline 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 huina o ka honua. I waena o lākou, hiki i nā kumuwaiwai graphite crystalline o ka moku ʻo Heilongjiang ke helu no 60% o Kina a ʻoi aku ma mua o 40% o ka honua, kahi e hoʻokani nei i kahi kuleana koʻikoʻi. ʻO Kina nā mea hana nui o ka honua o ka graphite crystalline, ukali ʻia e India a me Brazil.
Ka hoʻokaʻawale ʻana i nā kumuwaiwai
ʻO ke kua honua o nā waihona graphite crystalline ma nā wahi like ʻole o Kina
Nā ʻano unahi o nā waihona graphite crystalline nui ma Kina a me ka hua o nā unahi nui (>0.15mm)
ʻĀpana Heilongjiang
He ākea ka hoʻolaha ʻana o ka graphite ma ka Panalāʻau ʻo Heilongjiang, a he maikaʻi loa ia ma Hegang lāua ʻo Jixi. ʻO kona ʻāina hikina ka waihona nui loa o ka graphite crystalline ma ka ʻāina, me nā waihona graphite kaulana a me nā waihona graphite nui loa e like me Jixi Liumao, Luobei Yunshan lāua ʻo Muling Guangyi. Ua loaʻa nā lua graphite ma 7 o nā kūlanakauhale 13 o ka panalāʻau. ʻO ka nui o nā waihona waiwai i manaʻo ʻia he 400 miliona tons, a ʻo ka nui o nā kumuwaiwai hiki ke loaʻa ma kahi o 1 biliona tons. Loaʻa iā Mudanjiang lāua ʻo Shuangyashan nā ʻike nui, akā ua noʻonoʻo pono ʻia ke ʻano o nā kumuwaiwai. ʻO Hegang lāua ʻo Jixi ke aliʻi nei i ka graphite kiʻekiʻe. Ua manaʻo ʻia hiki i nā waihona graphite hiki ke hoʻōla ʻia ma ka panalāʻau ke hiki i 1-150 miliona tons (ka nui o ka mineral).
ʻĀpana Kūʻokoʻa o Mongolia I loko
ʻO nā waihona o ka graphite crystalline ma Inner Mongolia ka lua ma Heilongjiang wale nō, i hoʻolaha nui ʻia ma Inner Mongolia, Xinghe, Alashan a me Baotou.
ʻO ke ʻano kalapona paʻa o ka ʻaihao graphite ma ka ʻāina ʻo Xinghe ma waena o 3% a me 5%. ʻO ke anawaena o ke anawaena he >0.3mm, e helu ana ma kahi o 30%, a ʻo ke anawaena o ke anawaena he >0.15mm, hiki ke piʻi aku ma mua o 55%. Ma ka ʻāina ʻo Alashan, e lawe ana i ka waihona graphite ʻo Chahanmuhulu ma ke ʻano he laʻana, ʻo ke anawaena awelika o ke kalapona paʻa o ka ʻaihao he 5.45%, a ʻo ka hapa nui o nā unahi graphite he >0.15 mm. ʻO ka awelika o ke anawaena kalapona paʻa o ka lua graphite ma ka ʻāina ʻo Chaganwendu o Damao Banner ma ka ʻāina ʻo Baotou he 5.61% a ʻo ke anawaena unahi he <0.15mm.
Panalāʻau ʻo Sichuan
ʻO nā kumuwaiwai graphite crystalline ma ka Panalāʻau ʻo Sichuan ua hoʻolaha nui ʻia ma nā ʻĀpana ʻo Panzhihua, Bazhong a me Aba. ʻO ka awelika o ke kalapona paʻa i loko o ka ore graphite ma nā wahi ʻo Panzhihua a me Zhongba he 6.21%. He mau unahi liʻiliʻi ka nui o ka ore, a ʻaʻole i ʻoi aku ka nui o ke unahi ma mua o 0.15mm. ʻO ke anakahi kalapona paʻa o ka ore graphite crystalline ma ka ʻāpana ʻo Nanjiang o ke kūlanakauhale ʻo Bazhong he 5% a 7%, ʻo ke kiʻekiʻe loa he 13%, a ʻo ka hapa nui o nā unahi graphite he >0.15 mm. ʻO ke anakahi kalapona paʻa o ka ore graphite ma ka ʻĀpana ʻo Aba he 5% ~ 10%, a ʻo ka hapa nui o nā unahi graphite he <0.15mm.
Panalaau o Shanxi
Ua loaʻa i ke Kalana ʻo Shanxi he 8 mau kumu o nā waihona crystalline i ʻike ʻia o nā minelala graphite crystalline, i hoʻolaha nui ʻia ma ka ʻāina ʻo Datong. ʻO ka awelika o ke kalapona paʻa i loko o ka waihona ma waena o 3% a me 4%, a ʻo ka hapa nui o nā unahi graphite he >0.15 mm. Hōʻike ka hoʻāʻo ʻana i ka ʻaila ʻo ka hua nui e pili ana ma kahi o 38%, e like me ka lua graphite ma ke Kauhale ʻo Qili, ʻĀpana ʻo Xinrong, Datong.
Panalāʻau ʻo Shandong
ʻO nā kumuwaiwai graphite crystalline ma ka moku ʻo Shandong ua hoʻolaha nui ʻia ma Laixi, Pingdu a me Laiyang. ʻO ka awelika o ke kalapona paʻa ma ka villa hema 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 o ke kalapona paʻa ma ka lua graphite Liugezhuang ma ke kūlanakauhale ʻo Pingdu ma kahi o 3.34%, a ʻo ke anawaena unahi he <0.5mm ka hapa nui. ʻO ka awelika o ke kalapona paʻa o ka Pingdu Yanxin Graphite Mine he 3.5%, a ʻo ke anawaena o ke anakahi he >0.30mm, e helu ana no 8% a 12%. I ka hōʻuluʻulu manaʻo, ʻo ka awelika o ke kalapona paʻa i nā lua 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
He maikaʻi nā pae ʻoihana o nā waihona graphite o Kina, he maikaʻi ia no ka hana ʻeli ʻana, a ʻaʻole emi iho ka pae graphite crystalline ma mua o 3%. I nā makahiki he 10 i hala iho nei, ʻo ka hana makahiki o Kina o ka graphite ma waena o 60,000 a me 800,000 tons, a ʻo ka hana ʻana o ka graphite crystalline ma kahi o 80%.
Aia ma mua o hoʻokahi tausani mau ʻoihana hana graphite ma Kina, a ʻo nā huahana he mau huahana mineral graphite e like me ke graphite kalapona waena a me ke kiʻekiʻe, graphite maʻemaʻe kiʻekiʻe a me ka graphite pauka maikaʻi, a me nā mea graphite i hoʻonui ʻia a me nā mea kalapona. ʻO ke ʻano o ka ʻoihana he mea nui ia e ka mokuʻāina, kahi i hoʻolaha nui ʻia ma Shandong, Inner Mongolia, Hubei, Heilongjiang, Zhejiang a me nā wahi ʻē aʻe. He kahua paʻa ko ka ʻoihana mining graphite a ka mokuʻāina a he mau pono koʻikoʻi i ka ʻenehana a me nā kumuwaiwai.
Hoʻohana nui ʻia ka Graphite i ke kila, ka metallurgy, ka foundry, nā lako mīkini, ka ʻoihana kemika a me nā ʻoihana ʻē aʻe ma muli o kona mau waiwai maikaʻi loa. Me ka holomua o ka ʻepekema a me ka ʻenehana, ke noiʻi mālie ʻia nei ka hiki ke hoʻohana ʻia o nā mea graphite hou i nā ʻoihana ʻenehana kiʻekiʻe e like me ka ikehu hou, ka ʻoihana nukelea, ka ʻike uila, ka aerospace a me ka pale kaua, a ua manaʻo ʻia he kumuwaiwai koʻikoʻi e pono ai no ka hoʻomohala ʻana i nā ʻoihana e kū mai ana. I kēia manawa, hoʻohana nui ʻia nā huahana graphite a Kina i nā mea refractory, nā hoʻoheheʻe ʻana, nā sila, ka graphite kūikawā a me nā ʻoihana ʻē aʻe, kahi i hoʻohana nui ʻia ai nā mea refractory a me nā hoʻoheheʻe ʻana.
Me ka hoʻomau ʻana o ka hoʻomohala ʻana o ka ʻoihana ikehu hou, e hoʻomau ka hoʻonui ʻana o ke koi no ka graphite i ka wā e hiki mai ana.
Wānana no ke koi ʻana o ka graphite ma Kina i ka makahiki 2020
