ʻO ka Bauxite (bauxite ore) e pili ana i kahi huaʻōlelo hui no nā minerale hiki ke hoʻohana ʻia i ka ʻoihana, ka mea nui i haku ʻia me ka gibbsite, boehmite, a i ʻole diaspore. He punawai hiki ʻole ke hoʻololi ʻia. He keʻokeʻo ka bauxite maʻemaʻe a hiki ke ʻike ʻia ka hina hina, ʻōmaʻomaʻo ʻōmaʻomaʻo, a i ʻole ʻulaʻula ma muli o nā haumia like ʻole. Loaʻa i ka Bauxite ka nui o nā noi ʻoihana. Ma ka lima hoʻokahi, ʻo ia ka mea kumu nui no ka hana ʻana i ka alumina, ka mea e hana ai i ka alumini. Ma ka ʻaoʻao ʻē aʻe, hoʻohana nui ʻia ia ma ke ʻano he mea maka i nā ʻoihana e like me nā mea refractory, fused corundum, nā mea wili, nā huahana seramika, nā huahana kemika, a me ka slurry alumina kiʻekiʻe.

 

Loaʻa i ka calcined bauxite ka alumina hydrated a me ka alumini hydroxide, i loaʻa ma ka calcining bauxite kiʻekiʻe ma nā wela kiʻekiʻe (85 ° C a 1600 ° C) i loko o kahi kiln rotary. ʻO ia kekahi o nā mea waiwai nui no ka hana ʻana i ka alumini. Ke hoʻohālikelike ʻia me ka bauxite kumu, ma hope o ka wehe ʻana i ka wai ma o ka calcination, hiki ke hoʻonui ʻia ka ʻike alumina o ka bauxite calcined mai kahi o 57% a 58% o ka bauxite kumu i 84% a 88%.

Nā noi

 

  1. ʻOihana Alumini: loaʻa i ka bauxite ka waihona alumini kiʻekiʻe a he mea waiwai nui ia no ka ʻoihana hoʻoheheʻe alumini;
    2. Hoʻoheheʻe pololei: hiki ke hana ʻia ka bauxite i nā ʻano like ʻole o ka hoʻoheheʻe ʻana ma hope o ka hana ʻana, hoʻohana nui ʻia i ka kamaʻilio, nā mea kani, nā mīkini a me nā ʻoihana;
    3. Refractory mea: bauxite loaʻa nā waiwai maikaʻi e like me ka hoʻonui haʻahaʻa wela, ka refractoriness kiʻekiʻe, a me ka paʻa o ka leo wela kiʻekiʻe, e lilo ia i mea maʻamau no nā mea refractory. Hoʻohana nui ʻia nā mea refractory i hana ʻia i ke kila, non-ferrous metallurgy, petroleum, kemika a me nā ʻoihana ʻoihana ʻē aʻe.
    4. Nā mea hana hale: hiki i ka pauka bauxite ke hoʻomaikaʻi i ka ikaika a me ka paʻakikī o nā mea e like me ka cement, mortar, a me ka paʻakai, me ka hoʻonui ʻana i ko lākou kūpaʻa a me ka pale ʻana i ka corrosion.
