ʻO Bauxite ke kumu o ka ʻai hiki ke hoʻohana ʻia i ka ʻoihana, a ua kapa ʻia ʻo ia ka ʻai i haku ʻia me ka gibbsite a me ka monohydrate ma ke ʻano he mau minelala nui. ʻO Bauxite ka mea maka maikaʻi loa no ka hana ʻana i ka alumini metala, a ʻo kāna hoʻohana ʻana he 90% o ka huina o ka bauxite o ka honua. ʻO nā kahua noi o ka bauxite he metala a me nā mea ʻole metala. ʻOiai he liʻiliʻi ka nui o nā mea ʻole metala, he ākea kona mau hoʻohana. Hoʻohana ʻia ka Bauxite i ka ʻoihana kemika, metallurgy, ceramics, nā mea refractory, abrasives, adsorbents, ʻoihana māmā, nā mea kūkulu hale, ʻoihana koa, a pēlā aku.
Nā waiwai o ka ʻaila a me ke ʻano o ka mineral
ʻO Bauxite kahi hui ʻana o nā minelala he nui (hydroxides, minerals clay, oxides, etc.) me ka alumini hydroxide ma ke ʻano he mea nui. Ua kapa ʻia hoʻi ʻo "bauxite" a maʻamau e komo pū me ka gibbsite. , Diaspore, boehmite, hematite, kaolin, opal, quartz, feldspar, pyrite a me nā minelala ʻē aʻe he nui, ʻo ka hoʻohui kemika o ia mea ʻo AI2O3, SiO2, Fe2O3, TiO2, lua. ʻO nā mea hoʻohui e komo pū me CaO, MgO, K2O, Na2O, S, MnO2 a me nā mea olaola, a pēlā aku, i keʻokeʻo, hina, hina-melemele, melemele-ʻōmaʻomaʻo, ʻulaʻula, brown, a pēlā aku.
Ka hoʻomaikaʻi ʻana a me ka hoʻomaʻemaʻe ʻana
Hiki i kekahi mau ʻāpana maka i ʻeli ʻia mai ka bauxite ke hoʻokō i nā koi o ka noi. Hoʻoholo ka bauxite maʻamau i ke kaʻina hana hoʻomaikaʻi ma muli o ke ʻano o nā minelala haumia e pili ana. I ka manawa like, he paʻakikī ke wehe i nā haumia e pili ana me nā minelala i loaʻa ka alumini i loko o kekahi mau bauxites ma ke ʻano mechanical a i ʻole ke kino.
01
Ka hoʻokaʻawale ʻana o ka pōmaikaʻi
Hiki ke hoʻokaʻawale ʻia ke one quartz granular a me ka bauxite pauka ma ka holoi ʻana, kānana ʻana a i ʻole nā ʻano hana hoʻokaʻawale e hoʻomaikaʻi i ka maikaʻi. He kūpono ia no ka boehmite me ka nui o ka silicon.
02
Ka hoʻomaikaʻi ʻana i ka umekaumaha
ʻO ka hoʻohana ʻana i ka beneficiation medium kaumaha hiki ke hoʻokaʻawale i ka pālolo ʻulaʻula i loaʻa ka hao i loko o ka bauxite, a hiki i ka mea hoʻohuihui wili ke wehe i ka siderite a me nā minelala kaumaha ʻē aʻe.
03
Ka hoʻokaʻawale magnetic
ʻO ka hoʻohana ʻana i ka hoʻokaʻawale magnetic nāwaliwali hiki ke wehe i ka hao magnetic i loko o ka bauxite, a me ka hoʻohana ʻana i nā lako hoʻokaʻawale magnetic ikaika e like me ka plate magnetic separator, ka vertical ring high gradient magnetic separator, electromagnetic slurry magnetic separator hiki ke wehe i ka hao oxide, titanium a me ka hao silicate, a pēlā aku. ʻO ke koho ʻana i nā mea magnetic nāwaliwali hiki ke hoʻonui i ka ʻike alumini me ka hoʻemi ʻana i ke kumukūʻai o ka hana ʻana a me ka hana ʻana o ka alumina.
04
Lana ʻana
No nā sulfides e like me ka pyrite i loko o ka bauxite, hiki ke hoʻohana ʻia ka flotation xanthate e wehe; hiki ke hoʻohana ʻia ka flotation maikaʻi a me ka hoʻohuli e wehe i nā mea haumia e like me ka pyrite, titanium, silicon, a i ʻole ke koho ʻana i ka ʻike AI2O3 a hiki i ka 73% o ka bauxite maʻemaʻe kiʻekiʻe.
Ke hana ʻana i ka alumina
Hoʻohana nui ʻia ke kaʻina hana Bayer e hana i ka alumina mai ka bauxite. He maʻalahi kēia kaʻina hana, haʻahaʻa ka hoʻohana ʻana i ka ikehu a me ke kumukūʻai, a maikaʻi ke ʻano o ka huahana. ). No ka bauxite me ka ratio haʻahaʻa o ka alumini i ka silicon, ua hoʻohana ʻia ke ʻano sintering soda lime, a hiki ke hoʻohana ʻia ke ʻano Bayer a me ke ʻano sintering soda lime i kahi kaʻina hana hui pū ʻia.
Ka hana ʻana o ka paʻakai alumini
Me ka bauxite, hiki ke hana ʻia ka alumini sulfate e ke ʻano sulfuric acid, a hiki ke hana ʻia ka polyaluminum chloride e ke ʻano hoʻoheheʻe waikawa hydrochloric kiʻekiʻe.

①Ka nānā ʻana i nā mea maʻamau a me ka ʻike ʻana i nā mea metala.
②ʻO ka wehe ʻana a me ka hoʻomaʻemaʻe ʻana i nā minelala ʻaʻole metala, e like me ka ʻōlelo Pelekania, Kina, paheʻe, fluorescent, Gaoling, alumini ore, wax lau, kristal kaumaha a me nā minelala ʻaʻole metala ʻē aʻe.
