Bauxite kwenikweni amatanthauza mawu ambiri ore omwe angagwiritsidwe ntchito m'makampani, ndi gibbsite, boehmite kapena diaspore monga mchere waukulu.Magawo ake ogwiritsira ntchito ali ndi mbali ziwiri zachitsulo komanso zopanda zitsulo.Bauxite ndiye zida zabwino kwambiri zopangira zitsulo za aluminiyamu, komanso ndi gawo lofunikira kwambiri logwiritsira ntchito.Kugwiritsa ntchito kwake kumapangitsa zoposa 90% za kuchuluka kwa bauxite padziko lonse lapansi.

Kodi bauxite ndi chiyani?

Bauxite ndi mchere wadongo womwe umagwiritsidwa ntchito ngati zopangira zazikulu zopangira aluminiyamu.Imapangidwa ngati chinthu chotsalira kwazaka mamiliyoni ambiri ndi kusintha kwanyengo kwa miyala yokhala ndi aluminiyamu silicates.Idapezeka koyamba ku France mu 1821, ndipo idapezeka m'malo ambiri padziko lonse lapansi.Ruiqifeng wamanga ubale wolimba ndi Nthambi ya Guangxi ya CHALCO, yomwe ndi kampani yayikulu kwambiri ku China yopanga aluminiyamu, aluminiyamu yoyambira ndi zinthu zopangidwa ndi aluminiyamu.

Kodi Bauxite amagwiritsidwa ntchito pati?

The sanali zitsulo ntchito bauxite makamaka ngati zipangizo refractory zipangizo, abrasive zipangizo, mankhwala ndi mkulu aluminiyamu simenti.Ngakhale kuti gawo la bauxite lomwe limagwiritsidwa ntchito pazinthu zopanda zitsulo ndi laling'ono, limagwiritsidwa ntchito mosiyanasiyana.Mwachitsanzo: ponena za mankhwala, sulphate, trihydrate ndi aluminiyamu kolorayidi angagwiritsidwe ntchito kupanga mapepala, kuyeretsa madzi, zoumba ndi kuyeretsa mafuta;Adamulowetsa alumina angagwiritsidwe ntchito ngati chothandizira, chothandizira chonyamulira ndi chothandizira mu mankhwala, mafuta kuyenga ndi mafakitale mankhwala.Decolorization, kuchepa madzi m'thupi, degassing, deacidification, kuyanika ndi zina adsorbents thupi.

Aluminiyamu yachitsulo ndi chitsulo chachiwiri chofunika kwambiri padziko lonse, pambuyo pa chitsulo.Mu 1995, kuchuluka kwa anthu padziko lonse lapansi kunafikira 3.29kg.Chifukwa cha mphamvu yokoka yaying'ono, magetsi abwino ndi matenthedwe matenthedwe, makina osavuta ndi zinthu zina zabwino kwambiri, aluminiyamu imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana azachuma cha dziko.Pakali pano, kugwiritsidwa ntchito kwakukulu kwa aluminiyumu padziko lonse lapansi kuli m'magawo omanga, oyendetsa ndi kulongedza katundu, zomwe zimaposa 60% yazomwe zimagwiritsidwa ntchito.Aluminium ndi chinthu chofunikira kwambiri pamakampani opanga magetsi, makampani opanga ndege, makina opanga makina ndi zida zapagulu.

Lumikizanani ndiife kuti tifunsire zina.
