Hōʻike manaʻo Spodumene
ʻO ka molecular formula o spodumene ʻo LiAlSi2O6, ʻo ka density he 3.03 ~ 3.22 g / cm3, ʻo ka paʻakikī he 6.5-7, non-magnetic, luster glassy, ʻo ka theoretical grade o Li2O he 8.10%, a ʻo ka spodumene he columnar, granular a pā paha. -like. ʻO ka'ōnaehana kristal monoclinic,ʻo kona mau kala maʻamau he poni, hina-'ōmaʻomaʻo, melemele a hina-keʻokeʻo.ʻO ka lithium he metala māmā me nā mea kino kūikawā a me nā mea kemika. Ua hoʻohana nui ʻia i ka ʻoihana koa i nā lā mua a ua manaʻo ʻia he mea hoʻolālā. I kēia manawa, aia ma mua o 100 mau ʻano lithium a me kāna mau huahana. Hoʻohana nui ʻia ʻo Lithium i ka hana ʻana i nā pā lithium kiʻekiʻe, nā mea hoʻohui i ka electrolysis o ka alumini, a me nā lubricants haʻahaʻa haʻahaʻa. Eia kekahi, ʻo ka hoʻohana ʻana i ka ʻoihana o nā ceramics aniani, nā mea uila uila, ka lāʻau lapaʻau a me ka ʻoihana kemika e ulu nui aʻe.
Ma ke ʻano he mineral lithium paʻa i ka lithium a ʻoi aku ka maikaʻi o ka hana ʻana i nā paʻakai lithium, spodumene ka mea nui i kahele ʻia ma Australia, Kanada, Zimbabwe, Zaire, Brazil a me Kina. ʻO nā mines spodumene ma Xinjiang Keketuohai, Ganzi a me Aba ma Sichuan, a me nā mines lepidolite ma Yichun, Jiangxi he waiwai nui i nā kumuwaiwai lithium. ʻO lākou nā wahi nui no ka ʻeli ʻana i nā mineral lithium paʻa i Kina.
ʻO Spodumene concentrate grade
Hoʻokaʻawale ʻia nā concentrates Spodumene i nā hoʻohana like ʻole a me nā māka. Hōʻike ʻia ka maʻamau no nā māka o ka hoʻopuka concentrate ma ka papa ma lalo nei. Hoʻokomo ʻia nā māka puka concentrate i ʻekolu mau ʻāpana: haʻahaʻa hao lithium concentrate, lithium concentrate no nā ceramics a me lithium concentrate no ka ʻoihana kemika.
ʻO ke ala hoʻopōmaikaʻi ʻo Spodumene ore
Hoʻopili ʻia ka hoʻokaʻawale ʻana o ka spodumene e nā kumu he nui, e like me: symbiosis mineral, ʻano ʻano ʻano o ka ʻano, a me nā mea ʻē aʻe, e koi ana i nā kaʻina hana pono like ʻole.
Holoi:
ʻO ka hoʻokaʻawale ʻana i ka spodumene mai nā mineral silicate me ka hana flotation like he paʻakikī i nā ʻano flotation spodumene ma ka home a ma waho. Hiki ke hoʻokaʻawale ʻia ke kaʻina hana flotation Spodumene i ke kaʻina flotation hoʻohuli a me ke kaʻina flotation maikaʻi. Hiki ke hoʻokaʻawale ʻia nā minerala lithium nui e ka flotation, ʻoi loa no ka spodumene me ka haʻahaʻa haʻahaʻa, ka maikaʻi, ka mea paʻakikī, ʻo ka flotation he mea nui loa.
Mākēneki hoʻokaʻawale:
Hoʻohana maʻamau ka hoʻokaʻawale ʻana i ka hao no ka wehe ʻana i nā mea haumia hao i loko o ka lithium concentrates a i ʻole e hoʻokaʻawale i ka hao-lepidolite magnetic nāwaliwali. Ma ka hana hana, ʻo ka spodumene concentrate i loaʻa ma ke ʻano flotation i kekahi manawa he nui nā mea haumia hao. No ka hōʻemi ʻana i ka ʻike o nā mea hao, hiki ke hoʻohana ʻia ka hoʻokaʻawale magnetic no ka mālama ʻana. ʻO ka mea hoʻokaʻawale hoʻokaʻawale he mea hoʻokaʻawale magnetic paʻa pahu-type magnetic, kahi mea hoʻokaʻawale magnetic plate-type magnetic ikaika, a me ke apo kūpaʻa kiʻekiʻe-gradient magnetic separator. ʻO ka spodumene tailing ka mea nui o feldspar, a hiki ke hoʻohana ʻia nā mea hoʻokaʻawale magnetic kiʻekiʻe-gradient a me nā mea hoʻokaʻawale electromagnetic slurry e hoʻoneʻe i nā mea haumia e loaʻa ai nā huahana feldspar e hoʻokō i nā koi no nā kumu ceramic.
ʻO ke ʻano haʻahaʻa haʻahaʻa:
Ma lalo o nā kūlana wela maʻamau, ʻoi aku ka nui o ka nui o ka spodumene i loko o ka ʻaila spodumene ma mua o nā minerala gangue e like me ka quartz a me ka feldspar, ma kahi o 3.15 g/cm3. ʻO ka mea maʻamau, hoʻokaʻawale ʻia ka ʻaila spodumene ma o ka hoʻohana ʻana i ka wai kaumaha me ka haʻahaʻa ma waena o ka density o spodumene, quartz a me feldspar, e like me tribromomethane a me tetrabromoethane. Ma waena o lākou, ʻoi aku ka nui o ka spodumene ma mua o kēia mau wai kaumaha, no laila e hāʻule i lalo a hoʻokaʻawale ʻia mai nā minerala gangue e like me ka feldspar a me ka quartz.
ʻO ke ʻano o ka pōmaikaʻi hui:
I kēia manawa, paʻakikī ka loaʻa ʻana o ka lithium concentrates no nā mineral lithium "ʻilihune, maikaʻi, a me nā ʻano like ʻole" ma ke ʻano hoʻokahi o ka pōmaikaʻi. Pono e hoʻohana ʻia ke ʻano o ka hui ʻana. ʻO nā kaʻina hana nui: flotation-gravity separation-magnetic separation combined process , Flotation-magnetic separation hui kaʻina, flotation-chemical treatment combined process, etc.
Nā laʻana o ka pōmaikaʻi spodumene:
ʻO ka mineral pono nui o ka spodumene ore i lawe ʻia mai Australia mai he spodumene, me ka Li2O maʻiʻo o 1.42%, ʻo ia ka mea hao lithium-grade. Nui nā minela ʻē aʻe i loko o ka ʻele. ʻO nā minerala gangue ka nui o ka feldspar, quartz, muscovite, a me ka hematite mine etc.
Hoʻopili ʻia ʻo Spodumene e ka wili ʻana, a ʻo ka nui o nā mea i koho ʻia e hoʻomalu ʻia i -200 mesh 60-70%. He nui ka nui o ka sludge mua loa i loko o ka oka mua, a me ka chlorite a me nā minelala ʻē aʻe i maʻalahi ke hoʻoheheʻe ʻia i ka wā o ka ʻohi ʻana a me ka wili ʻana i ke kaʻina hana e hoʻopilikia pinepine ia i ka flotation maʻamau o ka ʻaila. E hoʻoneʻe ʻia ka lepo maikaʻi ma o ka hana desliming. Ma o ke kaʻina hana o ka hoʻokaʻawale magnetic a me ka flotation, loaʻa nā huahana ʻelua, spodumene concentrate a me feldspar concentrate, hiki ke hoʻohana ʻia e like me ka ceramic raw material.
