ʻO ka Bauxite e pili ana i ka huaʻōlelo maʻamau no nā ores i hiki ke hoʻohana ʻia i ka ʻoihana, me ka gibbsite, boehmite a i ʻole diaspore ʻo ia nā minerala nui.ʻElua mau ʻano o ka metala a me ka metala ʻole.ʻO Bauxite ka mea waiwai maikaʻi loa no ka hana ʻana i ka metala alumini, a ʻo ia hoʻi ke kahua noi nui loa.ʻOi aku ka nui o kāna ʻai ʻana ma mua o 90% o ka nui o ka bauxite o ka honua.

He aha ka bauxite?

ʻO Bauxite kahi mineral pālolo i hoʻohana ʻia ma ke ʻano he kumu nui no ka hana alumini.Hoʻokumu ʻia ʻo ia ma ke ʻano he huahana koena ma luna o nā miliona mau makahiki e ka hoʻoheheʻe ʻana i nā pōhaku i loaʻa nā silicate aluminika.Ua ʻike mua ʻia ia ma Farani i ka makahiki 1821, a ua ʻike ʻia ma nā wahi he nui a puni ka honua.Ua kūkulu ʻo Ruiqifeng i kahi pilina paʻa me Guangxi Branch o CHALCO, ʻo ia ka mea hana nui loa o Kina i ka alumina, ka alumini kumu a me nā huahana i hoʻoponopono ʻia.

Ma hea kahi i hoʻohana ʻia ai ka Bauxite?

ʻO ka hoʻohana ʻole ʻana o ka bauxite ka mea maʻamau e like me nā mea maka no nā mea refractory, nā mea abrasive, nā kemika a me ka sima alumina kiʻekiʻe.ʻOiai ka liʻiliʻi o ka hapa o ka bauxite i hoʻohana ʻia i nā ʻano non-metallic, he ākea ka hoʻohana ʻana.No ka laʻana: ma ke ʻano o nā huahana kemika, hiki ke hoʻohana ʻia ka sulfate, trihydrate a me ka alumini chloride i ka hana pepa, hoʻomaʻemaʻe wai, seramika a me ka hoʻomaʻemaʻe ʻaila;hiki ke hoʻohana ʻia ka alumina hoʻoikaika ʻia e like me ka catalyst, catalyst carrier a me ka catalyst i ka kemika, ka ʻaila hoʻomaʻemaʻe a me nā ʻoihana lāʻau.Decolorization, dehydration, degassing, deacidification, maloʻo a me nā adsorbents kino ʻē aʻe.

ʻO ka alumini metala ka lua metala nui loa ma ka honua, ma hope o ke kila.I ka makahiki 1995, ua hiki i ka 3.29kg ka hoʻohana ʻana i kēlā me kēia kanaka.Ma muli o kona umekaumaha liʻiliʻi, maikaʻi ka uila a me ka thermal conductivity, maʻalahi machining a me nā waiwai maikaʻi ʻē aʻe he nui, hoʻohana nui ʻia ka alumini i nā ʻāpana like ʻole o ka hoʻokele waiwai aupuni.I kēia manawa, ʻoi aku ka nui o ka hoʻohana alumini ma ka honua i ke kūkulu ʻana, ka lawe ʻana a me nā ʻāpana ʻāpana, ʻoi aku ka nui ma mua o 60% o ka nui o ka hoʻohana alumini.ʻO ka alumini ka mea waiwai nui no ka ʻoihana uila, ʻoihana hana mokulele, ʻoihana mīkini a me nā mea pono kīwila.
