E kūʻai i nā bauxite kūlohelohe i kā mākou hale kūʻai


He pōhaku sedimentary ka Bauxite me kahi aniani alumina kiʻekiʻe kiʻekiʻe. ʻO ia ka mea nui o ka honua a me ka gallium. ʻO ka Bauxite ka hapanui o nā mineralbbsite aluminium, boehmite a me ka diaspore, i hui pū ʻia me ka ʻelua o nā oxides goite a me nā hematite, nā alumini mineral kaolinite mineral a me nā mea liʻiliʻi o ka anatase a me ka ilmenite.

Ua hoʻohālikelike ʻia nā papa helu papa no nā bauxite.

ʻO Vadász (1951) i wehe i ka bauxite laterit (silicate) mai nā kares bauxite ores (carbonate):

  • Hoʻolaha nui ka mau kaola carbonate ma ʻEulopa, Guyana, a me Jamaica ma luna o nā pōhaku carbonate (limestone a dolomite), kahi i hana ʻia ai e ka makehula hope aku a me ka hōʻuluʻulu ʻana o nā pāluna pālolo - nā puʻu i puʻu ʻia i hoʻoili ʻia e nā kāpili a nā kāpili i hoʻohemo ʻia i ka wā o ke kūlohelohe. . ^ E Ha yM.
  • Loaʻa ka nui o nā pōhaku muri ma nā ʻāina o nā mokupuni. Ua hoʻokumu ʻia lākou e lateritization o nā pōhaku silicate e like me ka granite, gneiss, basalt, syenite, a me shale. No ka hoʻohālikelike ʻana me nā miʻa hope o ka hao, ʻo ke kūkulu ʻana o kēia mau pōhaku e hilinaʻi hou aku ma luna o nā kūlana hoʻohua wela i kahi wahi me kahi pākuʻi maikaʻi loa. ʻAe kēia i ka hoʻopau ʻana o ka kaolinite a me ka ua o ka gibbsite. Aia nā ʻenehana me nā kaila alumini kiʻekiʻe loa ma lalo o kahi papa pānaʻi ferruginous. ʻO ka hydroxide alumini i nā waihona muri bauxite hope loa a aneane like ʻole ka gibbsite.

I ke ʻano o Jamaica, ua hōʻike mai ka hōʻike noiʻi o nā ʻāina i kahi kiʻekiʻe o ka cadmium, hōʻike ʻia ana i ka wai o ka pualite mai nā hāmeʻa mai Miocene mai nā mokulele mai nā makahiki nui o ka lua pele i ʻAmelika Tengah.

ʻO Australia kahi mea hana nui o ka bauxite, a ukali ʻia e Kina. I ka makahiki 2017, ʻo Kina ka mea hana nui o ka alumini me kahi hapa o ka hana o ka honua, i ukali ʻia e Rusia, Canada a me India. ʻOiai ke ʻemi nui nei ka noi alumina, ʻike ʻia nā kaila o kona mau pōhaku kō e hiki ai i ke koi ʻana i ke ao holoʻokoʻa no ka alumina no nā kenekulia. Hoʻoulu i ka uila recycling, i loaʻa ka pono i ka hoʻohaʻahaʻa ʻana i ke kumukūʻai ma ka mana uila i ka hana ʻana i konumeki, a laila e hoʻonui nui ʻia nā kaila o ka honua.

ʻO ka manaʻo Bauxite

ʻO ka ʻāpana aʻe i kahi ʻepekema a e pili ana i nā manaʻo moʻomeheu.

Hiki ke hoʻohana ʻia ka pōhaku Bauxite ma ka noʻonoʻo ʻana, a maikaʻi paha paha kēia e kōkua iā ʻoe e kiʻi i nā pane i nā kūlana e pili ana iā ʻoe

Hiki iā ia ke hoʻomaopopo i ka makemake o nā poʻe ʻē aʻe. Ua ʻike ʻia no ke kōkua ʻana i hana i ka hoʻonui ʻia o ka hauʻoli a hoʻonui i ka maikaʻi.

ʻAʻole ia e hana koke akā inā mālama ʻia ʻoe ma kou wahi, he hana kona ikaika e hoʻowalewale iā ʻoe i ke ʻano o ka manawa.

Ma ke kōkua ʻana iā ʻoe e hoʻokuʻu i nā pilikia kūloko e pale iā ʻoe i ka hoʻokō ʻana i ka mea āu e makemake ai, e kōkua paha iā ʻoe e hoʻokuʻu i nā manaʻo i kumu e huhū ai ʻoe a e huhū paha i nā kūlana o kou ola.

ʻO Bauxite, mai Australia mai

E kūʻai i nā bauxite kūlohelohe i kā mākou hale kūʻai
