ʻO ka flake graphite he mineral laha ʻole hiki ke hoʻololi hou ʻia, i hoʻohana nui ʻia i ka ʻoihana hou a he kumu waiwai koʻikoʻi. Ua helu ka European Union i ka graphene, ka huahana pau o ka hana graphite, ma ke ʻano he papahana ʻenehana hae nui i ka wā e hiki mai ana, a ua helu ʻia ka graphite ma ke ʻano he 14 o nā kumu waiwai kolake "ola-a-make". Hoʻopaʻa inoa ʻo ʻAmelika Hui Pū ʻIa i nā kumuwaiwai flake graphite ma ke ʻano he kumu koʻikoʻi koʻikoʻi no nā ʻoihana ʻenehana kiʻekiʻe. He 70% o ka honua ka waihona graphite o Kina, a ʻo ia ka mea hoʻopaʻa graphite nui loa a me ka mea kūʻai aku ma ka honua. Eia nō naʻe, nui nā pilikia i ka hana hana, e like me ka ʻōpala ʻana, ka liʻiliʻi o ka hoʻohana ʻana i nā kumuwaiwai a me nā pōʻino koʻikoʻi o ke kaiapuni. ʻAʻole hōʻike ʻia ka waiwai maoli o ka liʻiliʻi o nā kumuwaiwai a me nā kumukūʻai o waho. ʻO nā pilikia kaʻana like ʻana o nā mea hoʻoponopono graphite Furuite i hōʻike nui ʻia ma nā ʻano aʻe:
ʻO ka mua, pono e hoʻoponopono koke ʻia ka ʻauhau waiwai. ʻO ka ʻauhau haʻahaʻa: ʻO ka ʻauhau kumu waiwai graphite o Kina i kēia manawa he 3 yuan no ke tona, he māmā loa a ʻaʻole ia e hōʻike i ka liʻiliʻi o nā kumuwaiwai a me ke kumukūʻai o waho o ke kaiapuni. Ke hoʻohālikelike ʻia me nā ʻāina laha ʻole me ka liʻiliʻi a me ke koʻikoʻi o ka mineral like, ma hope o ka hoʻoponopono ʻana i ka ʻauhau waiwai honua, ʻaʻole i helu kaʻawale ʻia nā mea ʻauhau, akā ua hoʻonui ʻia ka ʻauhau ma mua o 10 mau manawa. Ma ka hoʻohālikelike ʻana, haʻahaʻa ka ʻauhau kumu waiwai o ka flake graphite. ʻO ka uku ʻauhau hoʻokahi: ʻo nā hoʻoponopono kuʻuna o kēia manawa no ka ʻauhau waiwai he uku ʻauhau hoʻokahi no ka graphite ore, ʻaʻole i māhele ʻia e like me ke ʻano o ka maikaʻi a me ke ʻano o ka graphite, a ʻaʻole hiki ke hōʻike i ka hana o ka ʻauhau waiwai i ka hoʻoponopono ʻana i ka loaʻa kālā ʻokoʻa. He mea ʻepekema ʻole ka helu ʻana ma ka nui o ke kūʻai ʻana: ua helu ʻia e ka nui o ke kūʻai aku, ʻaʻole ma ka nui maoli o nā minela i ʻeli ʻia, me ka noʻonoʻo ʻole i ka uku no ka pōʻino o ke kaiapuni, ka hoʻomohala kūpono o nā kumuwaiwai, nā kumukūʻai hoʻomohala a me ka pau ʻana o nā kumuwaiwai.
ʻO ka lua, ʻoi aku ka wikiwiki o ka lawe ʻana aku. ʻO Kina ka mea hana nui loa o ka honua i nā graphite flake maoli a ʻo ia ka mea hoʻopuka nui loa i nā huahana graphite kūlohelohe. Ma kahi ʻokoʻa loa i ka hoʻohana nui ʻana o Kina i nā kumuwaiwai flake graphite, nā ʻāina i kūkulu ʻia, e alakaʻi nei i ka ʻenehana o nā huahana graphite hohonu, hoʻokō i ka hoʻolālā o ke "kūʻai ʻana ma mua o ka mining" no ka graphite kūlohelohe a pale i ka ʻenehana. Ma ke ʻano he mākeke graphite nui loa ma Kina, ʻo ka lawe ʻana mai o Iapana he 32.6% o ka nui o nā mea i lawe ʻia aku ma waho o Kina, a ʻo kekahi hapa o ka ʻaila graphite i lawe ʻia e hāʻule i ke kai; ʻO Korea Hema, ma kekahi ʻaoʻao, ua hoʻopaʻa i kāna mau mines graphite ponoʻī a lawe mai i kahi helu nui o nā huahana me nā kumu kūʻai haʻahaʻa; He 10.5% ka nui o ka nui o ka lawe ʻana mai o ʻAmelika Hui Pū ʻIa i kēlā me kēia makahiki, a ua pale ʻia kāna waiwai graphite e ke kānāwai.
ʻO ke kolu, he nui loa ka hana. Pili loa nā waiwai o ka graphite i ka nui o kona mau unahi. Loaʻa nā ʻano nui like ʻole o ka flake graphite i ka hoʻohana ʻana, nā ʻano hana a me nā kahua noi. I kēia manawa, nele ka noiʻi ʻana i ka ʻenehana graphite ore me nā ʻano like ʻole ma Kina, a ʻaʻole i ʻike ʻia ka hāʻawi ʻana i nā kumuwaiwai graphite me nā unahi like ʻole, a ʻaʻohe ʻano hana hohonu e pili ana. He haʻahaʻa ka hoʻihoʻi ʻana o ka graphite beneficiation, a he haʻahaʻa ka hua o ka graphite flake nui. ʻAʻole maopopo nā hiʻohiʻona waiwai, a hoʻokahi ke ʻano hana. ʻO ka hopena, ʻaʻole hiki ke pale maikaʻi ʻia ka graphite flake nui a ʻaʻole hiki ke hoʻohana pono ʻia ka graphite flake liʻiliʻi i ka wā o ka hana ʻana, e hopena ana i ka pau ʻana o nā kumu waiwai waiwai.
ʻO ka hā, he mea kupanaha ka ʻokoʻa kumu kūʻai ma waena o ka lawe ʻana mai a me ka lawe ʻana aku. ʻO ka hapa nui o nā huahana flake graphite maoli i hana ʻia ma Kina ka huahana mua loa i hana ʻia, a ʻo ka noiʻi a me ka hoʻomohala ʻana a me ka hana ʻana i nā huahana kiʻekiʻe i hoʻohui ʻia e ʻike ʻole ʻia. E lawe i ka graphite maʻemaʻe kiʻekiʻe ma ke ʻano he laʻana, alakaʻi nā ʻāina ʻē i ka graphite maʻemaʻe kiʻekiʻe me kā lākou pono ʻenehana, a pale i ko mākou ʻāina i nā huahana graphite kiʻekiʻe. I kēia manawa, hiki ʻole i ka ʻenehana graphite maʻemaʻe kiʻekiʻe o Kina ke hiki i ka maʻemaʻe o 99.95%, a ʻo ka maʻemaʻe o 99.99% a ʻoi aʻe ke hilinaʻi wale ʻia i ka lawe ʻana mai. Ma 2011, ʻo ke kumukūʻai maʻamau o ka graphite flake maoli ma Kina ma kahi o 4,000 yuan / ton, ʻoiai ke kumu kūʻai o ka 99.99% i lawe ʻia mai ka graphite maʻemaʻe kiʻekiʻe ma mua o 200,000 yuan / ton, a he mea kupaianaha ke kumukūʻai.
