【Huate Encyclopedia of Mineral Processing】Ka noiʻi ʻana a me ka hoʻohana ʻana i ka ʻenehana hoʻoponopono Bauxite.

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, light industry, building materials, military industry, 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 ka hui kemika ʻo ia ka nui 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 ʻala 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 nui 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 wehe 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, vertical ring high 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 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 ke kaʻina 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 o ka soda lime sintering, a hiki ke hoʻohana ʻia ke ʻano Bayer a me ka soda lime sintering ma 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 hoʻoheheʻe hydrochloric kiʻekiʻe.

ʻO ke ʻano lawelawe ʻenehana o Huate Beneficiation Engineering Design Institute

①Ka nānā ʻana o nā mea maʻamau a me ka ʻike ʻana i nā mea metala.
② ʻO ka wehe ʻana i ka haumia a me ka hoʻomaʻemaʻe ʻana i nā minerala non-metallic, e like me English, Chinese, sliding, fluorescent, Gaoling, alumini ore, leaf wax, heavy crystal and other non-metallic minerals.
③ ʻO ka pōmaikaʻi o ka hao, titanium, manganese, chromium, vanadium a me nā mineral non-ferrous ʻē aʻe.
④ ʻO ka pōmaikaʻi o nā minerala palupalu palupalu e like me ka tungsten ore, tantalum niobium ore, durian, uila, a me ke ao.
⑤ Hoʻohana piha i nā kumuwaiwai lua e like me nā huelo like ʻole a me ka hoʻoheheʻe ʻana.
⑥ʻO ka pōmaikaʻi hui ʻia o nā minela kala, magnetic, kaumaha, a me ka flotation.
⑦ Hoʻokaʻawale ʻia ka mea ʻike akamai i nā minerala ʻole a me nā minerala ʻole.
⑧ Hoʻāʻo koho hou semi-industrial.
⑨ ʻO ka hoʻohui ʻana i ka pauka superfine e like me ka ʻoki ʻana i nā mea, ka wili pōleʻa a me ka paʻi ʻana.
⑩EPC turnkey kaʻina hana e like me ka ʻoki ʻana, ke koho mua ʻana, ka ʻai ʻana, ka hoʻokaʻawale ʻana (kaumaha, flotation), ka hoʻonohonoho ʻana, a me nā mea ʻē aʻe no ke koho ʻana.
