Bauxite waxaa loola jeedaa macdanta loo isticmaali karo warshadaha, waxaana si wadajir ah loo tixraacaa sida macdanta ka kooban gibbsite iyo monohydrate oo ah macdanta ugu muhiimsan.Bauxite waa alaabta ceeriin ee ugu fiican ee soo saarista aluminium bir ah, isticmaalkeeduna waxa uu ka badan yahay 90% wax soo saarka bauxite ee adduunka.Goobaha codsiga ee bauxite waa bir iyo kuwa aan bir ahayn.Inkasta oo qadarka aan biraha ahayn uu yar yahay, waxay leedahay adeegsi ballaaran.Bauxite waxaa loo isticmaalaa warshadaha kiimikada, metallurgy, ceramics, alaabta refractory, abrasives, adsorbents, warshadaha iftiinka, qalabka dhismaha, warshadaha military, iwm.
Guryaha macdanta iyo dhismaha macdanta
Bauxite waa isku dhafka macdano badan (hydroxides, macdanta dhoobada, oxides, iwm) oo leh aluminium hydroxide oo ah qaybta ugu muhiimsan.Waxa kale oo loo yaqaan "bauxite" waxaana badanaa ku jira gibbsite., Diaspore, boehmite, hematite, kaolin, opal, quartz, feldspar, pyrite iyo macdano kale oo badan, kiimikaad ka kooban inta badan AI2O3, SiO2, Fe2O3, TiO2, secondary Waxyaabaha ay ka mid yihiin CaO, MgO, K2O, Na2O, S, MnO2 iyo walxaha organic, iwm, oo ah caddaan, cawl, cawl-jaal, huruud-cagaar, casaan, bunni, iwm.
Faa'iidada iyo nadiifinta
Qaar ka mid ah macdanta ceyriinka ah ee laga soo saaro bauxite waxay buuxin karaan shuruudaha codsiga.Bauxite caadiga ah ayaa go'aamisa habka ka faa'iidaysiga ee ku salaysan dabeecadda macdanta wasakhda ah ee la xidhiidha.Isla mar ahaantaana, wasakhda la xidhiidha macdanta aluminium-ku jirta ee bauxites qaarkood way adagtahay in laga saaro si farsamaysan ama jireed.
01
Kala soocidda faa'iidada
Ciidda quartz granular iyo bauxite budada ah waxaa lagu kala saari karaa dhaqidda, shaandhaynta ama hababka kala-saarista si tayada loo hagaajiyo.Waxay ku habboon tahay boehmite oo leh maaddo silikoon sare leh.
02
Ka faa'iidaysiga cuf-isjiidadka
Isticmaalka ka faa'iidaysiga dhexdhexaadka ah ee culus ayaa kala saari kara dhoobada cas ee birta ku jirta ee bauxite, iyo xoojinta lafdhabarta ayaa ka saari kara siderite iyo macdanta kale ee culus.
03
Kala soocida magnetic
Isticmaalka kala-soocidda magnetic daciif ah ka saari kartaa birta magnetic in bauxite ah, iyo isticmaalka qalabka kala soocida magnetic xoog leh sida saxan kala soocida magnetic, giraanta toosan sare gradient magnetic SEPARATOR, electromagnetic slurry magnetic Slurry ka saari kartaa birta oxide, titanium iyo silicate birta. iwm. Xulashada qalabka magnetic daciifka ah waxay kordhin kartaa maadada aluminiumka iyada oo la dhimayo kharashka wax soo saarka alumina iyo farsamaynta.
04
sabayn
Sulfide sida pyrite ku jira bauxite, xanthate flotation waxaa loo isticmaali karaa in meesha laga saaro;sabbeynta togan iyo dib-u-celinta ayaa sidoo kale loo isticmaali karaa in laga saaro wasakhda sida pyrite, titanium, silicon, ama dooro waxyaabaha AI2O3 ilaa 73% ee bauxite-nadiifinta sare.
Soo saarista aluminium
Habka Bayer waxaa inta badan loo isticmaalaa in laga soo saaro aluminium ka bauxite.Habkani waa mid sahlan, isticmaalka tamarta iyo kharashka ayaa hooseeya, tayada badeecaduna waa wanaagsan tahay.).Bauxite oo leh saamiga hoose ee aluminium iyo silikoon, habka soodhaha lime sintering ayaa la qaatay, iyo habka Bayer iyo habka soodhaha lime sintering sidoo kale waxaa loo isticmaali karaa habka wax soo saarka isku dhafan.
Wax soo saarka milixda aluminium
Iyadoo bauxite, aluminium sulfate waxaa lagu soo saari karaa habka sulfuric acid, iyo polyaluminum chloride waxaa lagu soo saari karaa habka heerkulka sare ee hydrochloric acid.
