ʻO ka Bauxite ka mea i hiki ke hoʻohana ʻia i ka ʻoihana, a ua kapa ʻia ʻo ia ʻo ka ore i haku ʻia me ka gibbsite a me ka monohydrate e like me nā minerala nui.ʻO ka Bauxite ka mea waiwai maikaʻi loa no ka hana ʻana i ka alumini metala, a ʻoi aku ka nui o kāna ʻai ʻana ma mua o 90% o ka huina bauxite o ka honua.ʻO nā māhele noi o ka bauxite he metala a me ka mea ʻole.ʻOiai he liʻiliʻi ka nui o ka metala ʻole, he ākea ka hoʻohana ʻana.Hoʻohana ʻia ʻo Bauxite i ka ʻoihana kemika, metallurgy, ceramics, refractory material, abrasives, adsorbents, ʻoihana māmā, hale kūkulu, ʻoihana koa, etc.
Nā waiwai ore a me ka hoʻolālā mineral
ʻO ka Bauxite kahi hui ʻana o nā minela he nui (hydroxides, pālolo, oxides, etc.) me ka alumini hydroxide ka mea nui.Kapa ʻia ʻo ia ʻo "bauxite" a loaʻa mau i ka gibbsite., Diaspore, boehmite, hematite, kaolin, opal, quartz, feldspar, pyrite a me nā mea ʻē aʻe he nui, ʻo ia ka mea nui o AI2O3, SiO2, Fe2O3, TiO2, lua ʻO nā mea hoʻohui me CaO, MgO, K2O, Na2O, S, MnO2 a me ka mea olaola, etc., i keʻokeʻo, hina, hina-melemele, melemele-'ōmaʻomaʻo, ulaula, brown, etc.
ʻO ka pōmaikaʻi a me ka hoʻomaʻemaʻe
Hiki ke hoʻokō i nā koi o ka noi ʻana i kekahi mau ʻeleʻele maka i ʻeli ʻia mai ka bauxite.Hoʻoholo ka bauxite maʻamau i ke kaʻina hana pono ma muli o ke ʻano o nā minerala haumia pili.I ka manawa like, paʻakikī nā mea haumia e pili ana i nā minerala alumini i loko o kekahi mau bauxite e wehe i ka mechanically a i ke kino paha.
01
Hoʻokaʻawale ʻana i ka pōmaikaʻi
Hiki ke hoʻokaʻawale ʻia ke one quartz granular a me ka pauka bauxite e ka holoi ʻana, kānana a i ʻole nā ʻano hana e hoʻomaikaʻi i ka maikaʻi.He kūpono ia no ka boehmite me ke kiʻekiʻe kiʻekiʻe.
02
Pōmaikaʻi gravity
Hiki i ka hoʻohana ʻana i ka waiwai kaumaha ke hoʻokaʻawale i ka pālolo ʻulaʻula i loko o ka bauxite, a hiki i ka spiral concentrator ke wehe i ka siderite a me nā mineral kaumaha ʻē aʻe.
03
Mākēneki hoʻokaʻawale
Hiki i ka hoʻohana ʻana i ka hoʻokaʻawale magnetic nāwaliwali ke hoʻoneʻe i ka hao magnetic i loko o ka bauxite, a me ka hoʻohana ʻana i nā mea hoʻokaʻawale magnetic ikaika e like me ka plate magnetic separator, ke apo kū i ke apo kiʻekiʻe gradient magnetic separator, electromagnetic slurry magnetic separator hiki ke wehe i ka hao oxide, titanium a me ka hao silicate, etc. ʻO ke kohoʻana o nā mea magnetic nāwaliwali hiki ke hoʻonui i ka mea alumini me ka ho'ēmiʻana i ke kumukūʻai o ka hana alumina a me ka hana.
04
Holoi
No nā sulfides e like me ka pyrite i loko o ka bauxite, hiki ke hoʻohana ʻia ka xanthate flotation e wehe;Hiki ke hoʻohana ʻia ka flotation maikaʻi a hoʻohuli e wehe i nā mea haumia e like me pyrite, titanium, silicon, a i ʻole koho AI2O3 maʻiʻo a hiki i ka 73% o ka bauxite maʻemaʻe kiʻekiʻe.
E hana ana i ka alumina
Hoʻohana nui ʻia ka 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 ka maikaʻi o ka huahana.).No ka bauxite me ka ratio haʻahaʻa o ka alumini a me ke silikoni, ua ʻae ʻia ke ʻano hana hoʻoheheʻe ʻana i ka soda lime, a hiki ke hoʻohana ʻia ke ʻano Bayer a me ke ʻano o ka soda lime sintering i kahi kaʻina hana hui.
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 wai wai wai wai kiʻekiʻe.
