Bauxite waxaa loola jeedaa macdanta loo isticmaali karo warshadaha, waxaana si wadajir ah loogu yeeraa macdanta laga sameeyay gibbsite iyo monohydrate sida macdanta ugu muhiimsan. Bauxite waa walaxda ugu fiican ee ceeriin ah ee lagu soo saaro aluminiumka birta ah, isticmaalkeeduna wuxuu ka badan yahay 90% wadarta guud ee wax soo saarka bauxite adduunka. Meelaha loo adeegsado bauxite waa bir iyo aan bir ahayn. Inkasta oo tirada aan bir ahayn ay yar tahay, haddana waxay leedahay isticmaal ballaaran. Bauxite waxaa loo isticmaalaa warshadaha kiimikada, birta, dhoobada, agabka iska caabiya, xoqidda, nuugayaasha, warshadaha fudud, agabka dhismaha, warshadaha militariga, iwm.
Sifooyinka macdanta iyo qaab-dhismeedka macdanta
Bauxite waa isku darka macdanno badan (hydroxides, macdan dhoobo ah, oksaydhyo, iwm.) oo leh aluminium hydroxide oo ah qaybta ugu weyn. Waxaa sidoo kale loo yaqaan "bauxite" badanaana waxaa ku jira gibbsite., Diaspore, boehmite, hematite, kaolin, opal, quartz, feldspar, pyrite iyo macdano kale oo badan, oo ka kooban kiimikooyin badan AI2O3, SiO2, Fe2O3, TiO2, secondary. Waxyaabaha ku jira waxaa ka mid ah CaO, MgO, K2O, Na2O, S, MnO2 iyo walxo dabiici ah, iwm., oo ah caddaan, cawl, cawl-jaalle, jaalle-cagaar, casaan, bunni, iwm.
Faa'iido iyo nadiifin
Macdanta cayriin ee laga soo saaro bauxite waxay buuxin kartaa shuruudaha codsiga. Bauxite-ka caadiga ah wuxuu go'aamiyaa habka loo isticmaalo iyadoo lagu saleynayo nooca macdanta wasakhda ah ee la xiriirta. Isla mar ahaantaana, wasakhda la xiriirta macdanta aluminiumka ku jirta ee ku jirta bauxite-ka qaarkood way adag tahay in si farsamo ahaan ama jir ahaanba looga saaro.
01
Kala soocidda Ka-faa'iidaysiga
Ciidda quartz-ka granular-ka ah iyo bauxite-ka budada ah waxaa lagu kala saari karaa iyadoo la dhaqo, la gooyo ama la kala saaro si loo hagaajiyo tayada. Waxay ku habboon tahay boehmite oo leh silicon sare.
02
Faa'iidada cufisjiidadka
Isticmaalka beneficiation dhexdhexaad ah oo culus ayaa kala saari kara dhoobada cas ee birta ku jirta ee ku jirta bauxite, ururiyaha wareegsanna wuxuu ka saari karaa siderite iyo macdanaha kale ee culus.
03
Kala soocidda birlabta
Isticmaalka kala-soocidda magnetic-ga ee daciifka ah waxay ka saari kartaa birta magnetic-ga ee ku jirta bauxite, iyo isticmaalka qalabka kala-soocidda magnetic-ga ee xooggan sida kala-soocidda magnetic-ga saxanka, kala-soocidda magnetic-ga ee giraanta toosan, kala-soocidda magnetic-ga ee slurry-ga electromagnetic-ga waxay ka saari kartaa birta oksaydhka, titanium iyo silicate-ka birta, iwm. Xulashada walxaha magnetic-ga ee daciifka ah waxay kordhin kartaa maaddada aluminium-ka iyadoo la dhimayo kharashka wax soo saarka iyo farsamaynta alumina.
04
Sabeynta
Sulfide-yada sida pyrite ee ku jira bauxite, xanthate flotation ayaa loo isticmaali karaa in laga saaro; spooling-ka togan iyo kan rogan ayaa sidoo kale loo isticmaali karaa in laga saaro wasakhda sida pyrite, titanium, silicon, ama xulashada waxyaabaha AI2O3 ilaa 73% ee bauxite saafi ah oo sarreeya.
Soo saarista alumina
Habka Bayer waxaa inta badan loo isticmaalaa in lagu soo saaro alumina laga helo bauxite. Habkani waa mid fudud, isticmaalka tamarta iyo kharashku waa hooseeyaan, tayada badeecaduna waa wanaagsan tahay.). Bauxite oo leh saamiga hoose ee aluminium iyo silicon, habka sintering lime soda ayaa la qaataa, habka Bayer iyo habka sintering lime soda ayaa sidoo kale loo isticmaali karaa habka wax soo saarka ee isku dhafan.
Soo saarista milixda aluminiumka
Iyada oo la adeegsanayo bauxite, aluminium sulfate waxaa lagu soo saari karaa habka sulfuric acid, polyaluminum chloride-na waxaa lagu soo saari karaa habka roobka hydrochloric acid ee heerkulka sare leh.
