Aia ka nui o nā mea hiki ʻole ke hoʻololi hou ʻia me ka waiwai waiwai kiʻekiʻe, e like me ka cobalt, lithium, nickel, copper, aluminum, etc. ʻAʻole hiki iā ia ke hoʻemi wale i ka pollution mai ka puʻupuʻu ʻōpala, akā e pale pū i ka hoʻopau ʻana i nā kumuwaiwai metala o ka cobalt, nickel. , a me nā mea ʻē aʻe ma o ka hana hou ʻana i nā ʻōpala a i ʻole nā pahu lithium ion kūpono ʻole.
Ua hui pū ʻo Ktkbofan Energy New Material Co. Ltd ma Changzhou me ke kulanui a ua hoʻokumu i kahi hui noiʻi e pili ana i ke kākoʻo mai nā kumu aʻoaʻo Jiangsu University of Technology, Jiangsu rare metala ʻenehana kaʻina hana a me ke keʻena hana kī noi. ʻO kāna kumuhana noiʻi ʻo ka hana hou ʻana i nā metala waiwai mai ka ʻōpala lithium ion pākahi. Ma hope o ʻekolu mau makahiki noiʻi a me ka hoʻomohala ʻana, ua hoʻoponopono ia i nā pilikia o ka hana paʻakikī, ka lōʻihi o ke kaʻina hana, nā pōʻino o ke kaiapuni mai ka mea hoʻoheheʻe organik, pōkole ʻenehana kaʻina hana, hoʻemi i ka hoʻohana ʻana i ka mana, hoʻomaikaʻi i ka helu o ka metala, ka maʻemaʻe a me ka hoʻihoʻi ʻana, ka mea e hoʻokō ai i ka makahiki. 8000 tons pauku lithium ion pākaukau i hoʻopaʻa hou ʻia a me ka noi.
No ka hoʻohana ʻana i nā kumuwaiwai paʻa kēia papahana. ʻO ke kumu ʻenehana ka hoʻokaʻawale ʻana a me ka hana hou ʻana i nā metala nonferrous e ka hydrometallurgical extraction, me ka leach, ka hoʻomaʻemaʻe hoʻonā a me ka noʻonoʻo ʻana, ka wehe ʻana i ka solvent, a me nā mea ʻē aʻe.
ʻO nā ʻanuʻu ʻenehana: ka hoʻomaʻamaʻa mua ʻana i ka ʻōpala lithium ion pākahi i ka wā mua, me ka hoʻokuʻu ʻana, ka wehe ʻana, ka wāwahi a me ka hoʻokaʻawale ʻana. A laila hana hou i ka plastik ma hope o ka wehe ʻana a me ka hao i waho. Wehe i nā mea electrode ma hope o ka leaching alkaline, ka leaching acid a me ka hoʻomaʻemaʻe.
ʻO ka unuhi ʻana ka hana nui e hoʻokaʻawale i ke keleawe mai ka cobalt a me ka nickel. A laila hoʻokomo ʻia ke keleawe i loko o ka pahu electrodeposition a hana i ka hana keleawe i waiho ʻia. E unuhi hou ma hope o ka unuhi ʻana o ka cobalt a me ka nickel. Hiki iā mākou ke kiʻi i ka paʻakai cobalt a me ka paʻakai nickel ma hope o ka ʻike ʻana i ka crystallized. A i ʻole e lawe i ka cobalt a me ka nickel ma hope o ka unuhi ʻia ʻana i loko o ka slot electrodeposition, a laila e hana i nā huahana cobalt a me ka nickel electrodeposition.
ʻO ka loaʻa ʻana o ka cobalt, keleawe a me ka nickel ma ke kaʻina hana electro-deposition he 99.98%, 99.95% a me 99.2%～99.9%. Ua hōʻea nā huahana cobaltous sulfate a me nickel sulfate i ke kūlana kūpono.
Loaʻa i ka noiʻi hoʻonui a me ka noiʻi ʻenehana a hoʻomohala i ka hoʻokō noiʻi i hoʻopaʻa ʻia, hoʻonohonoho i kahi laina hana maʻemaʻe piha o ka ʻōpala lithium ion me ka hoʻihoʻi makahiki ʻoi aku ma mua o 8000 tons, recycle 1500 tons cobalt, 1200 tons copper, 420 tons nickel, ka mea. ʻoi loa ke kumu kūʻai ma luna o 400 miliona yuan.
Ua ʻōlelo ʻia ʻaʻohe hydrometallurgy ma ka home. ʻAʻole ʻike ʻia ma nā ʻāina ʻē. Malia paha hiki iā mākou ke ho'āʻo e lawe i kēia ʻano i ka hoʻohana ākea.
He kūlana koʻikoʻi kēia hoʻokō i ka ʻōpala ʻāina Li ion pākaukau hana hou, a hoʻonui maikaʻi i ka mālama ʻana i ka ikehu. Hoʻohālikelike ʻia me nā ʻoihana pākaukau ʻē aʻe, loaʻa iā ia nā pōmaikaʻi e pili ana i ka pili o ka kaiapuni, ke kumu kūʻai haʻahaʻa a me ka loaʻa kālā kiʻekiʻe.
Hiki iā ia ke hoʻohui a maʻalahi i ke kaʻina hana ʻenehana e ka hydrometallurgy, he haʻahaʻa ka hoʻohana ʻana i ka ikehu akā kiʻekiʻe ka hoʻihoʻi huahana.
