Bauxite yog hais txog cov ore uas siv tau rau hauv kev lag luam, thiab feem ntau hu ua ore uas muaj gibbsite thiab monohydrate ua cov minerals tseem ceeb. Bauxite yog cov khoom siv raw zoo tshaj plaws rau kev tsim cov hlau txhuas, thiab nws cov kev siv nyiaj ntau dua 90% ntawm lub ntiaj teb tag nrho cov bauxite tsim tawm. Cov teb thov ntawm bauxite yog hlau thiab tsis yog hlau. Txawm hais tias cov khoom tsis yog hlau me me, nws muaj ntau yam kev siv. Bauxite yog siv rau hauv kev lag luam tshuaj lom neeg, metallurgy, ceramics, cov ntaub ntawv refractory, abrasives, adsorbents, kev lag luam lub teeb, cov ntaub ntawv tsim kho, kev lag luam tub rog, thiab lwm yam.
Cov khoom ntawm cov pob zeb thiab cov qauv ntawm cov pob zeb
Bauxite yog sib xyaw ntawm ntau yam minerals (hydroxides, av nplaum minerals, oxides, thiab lwm yam) nrog txhuas hydroxide ua lub ntsiab tivthaiv. Nws tseem hu ua "bauxite" thiab feem ntau suav nrog gibbsite. , Diaspore, boehmite, hematite, kaolin, opal, quartz, feldspar, pyrite thiab ntau lwm yam minerals, cov tshuaj lom neeg uas feem ntau yog AI2O3, SiO2, Fe2O3, TiO2, theem nrab. Cov khoom xyaw suav nrog CaO, MgO, K2O, Na2O, S, MnO2 thiab cov organic matter, thiab lwm yam., hauv dawb, grey, grey-daj, daj-ntsuab, liab, xim av, thiab lwm yam.
Kev pab thiab kev ntxuav
Qee cov hlau tsis huv uas tau khawb los ntawm bauxite tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm daim ntawv thov. Cov bauxite ib txwm txiav txim siab txog cov txheej txheem ua kom zoo raws li qhov xwm txheej ntawm cov zaub mov tsis huv. Tib lub sijhawm, cov khoom tsis huv uas cuam tshuam nrog cov zaub mov uas muaj txhuas hauv qee cov bauxites nyuaj rau tshem tawm los ntawm kev siv tshuab lossis lub cev.
01
Kev faib tawm ntawm kev pab cuam
Cov xuab zeb quartz granular thiab hmoov bauxite tuaj yeem sib cais los ntawm kev ntxuav, sieving lossis grading txoj kev kom zoo dua. Nws yog qhov tsim nyog rau boehmite nrog cov ntsiab lus silicon siab.
02
Kev pab txhawb nqa lub ntiajteb txawj nqus
Kev siv cov khoom siv hnyav nruab nrab tuaj yeem cais cov av nplaum liab uas muaj hlau hauv bauxite, thiab lub kauv concentrator tuaj yeem tshem tawm cov siderite thiab lwm yam minerals hnyav.
03
Kev sib cais sib nqus
Kev siv cov khoom sib cais sib nqus tsis muaj zog tuaj yeem tshem tawm cov hlau sib nqus hauv bauxite, thiab kev siv cov khoom siv sib cais sib nqus muaj zog xws li phaj sib nqus sib cais, lub nplhaib ntsug siab gradient sib nqus sib cais, electromagnetic slurry sib nqus sib cais tuaj yeem tshem tawm cov hlau oxide, titanium thiab hlau silicate, thiab lwm yam. Kev xaiv cov khoom siv sib nqus tsis muaj zog tuaj yeem ua rau cov ntsiab lus txhuas nce ntxiv thaum txo cov nqi ntawm alumina ntau lawm thiab ua tiav.
04
Kev ntab dej
Rau cov sulfides xws li pyrite uas muaj nyob hauv bauxite, xanthate flotation tuaj yeem siv los tshem tawm; qhov zoo thiab rov qab flotation kuj tseem siv tau los tshem tawm cov khoom tsis huv xws li pyrite, titanium, silicon, lossis xaiv cov ntsiab lus AI2O3 txog li 73% ntawm cov bauxite siab-purity.
Tsim cov alumina
Cov txheej txheem Bayer feem ntau yog siv los tsim alumina los ntawm bauxite. Cov txheej txheem no yooj yim, kev siv hluav taws xob thiab tus nqi qis, thiab cov khoom zoo. ). Rau bauxite nrog qhov sib piv qis ntawm txhuas rau silicon, txoj kev sintering soda lime tau txais yuav, thiab txoj kev Bayer thiab txoj kev sintering soda lime kuj tseem siv tau rau hauv cov txheej txheem ntau lawm ua ke.
Kev tsim cov ntsev txhuas
Nrog bauxite, txhuas sulfate tuaj yeem tsim los ntawm txoj kev sulfuric acid, thiab polyaluminum chloride tuaj yeem tsim los ntawm txoj kev kub siab hydrochloric acid precipitation.
