Bauxite yog hais txog cov ore uas tuaj yeem siv rau hauv kev lag luam, thiab suav nrog cov ore uas muaj gibbsite thiab monohydrate ua cov zaub mov tseem ceeb. Bauxite yog cov khoom siv zoo tshaj plaws rau kev tsim cov hlau txhuas, thiab nws cov nyiaj siv rau ntau tshaj 90% ntawm lub ntiaj teb tag nrho cov khoom tsim tawm bauxite. Daim ntawv thov teb ntawm bauxite yog hlau thiab tsis yog hlau. Txawm hais tias tus nqi ntawm cov hlau tsis yog me me, nws muaj ntau yam kev siv. Bauxite yog siv rau hauv kev lag luam chemical, metallurgy, ceramics, refractory cov ntaub ntawv, abrasives, adsorbents, lub teeb kev lag luam, cov ntaub ntawv hauv tsev, kev lag luam tub rog, thiab lwm yam.
Ore zog thiab ntxhia qauv
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 muaj pes tsawg leeg ntawm AI2O3, SiO2, Fe2O3, TiO2, theem nrab Cov khoom xyaw suav nrog CaO, MgO, K2O, Na2O, S, MnO2 thiab cov organic teeb meem, thiab lwm yam, hauv cov xim dawb, grey, grey-daj, daj-ntsuab, liab, xim av, thiab lwm yam.
Kev pab thiab purification
Qee cov ore mined los ntawm bauxite tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm daim ntawv thov. Cov pa bauxite txiav txim siab cov txheej txheem tau txais txiaj ntsig raws li qhov xwm txheej ntawm cov khoom siv impurity cuam tshuam. Nyob rau tib lub sijhawm, cov impurities cuam tshuam nrog aluminium-muaj cov ntxhia hauv qee cov bauxites nyuaj rau tshem tawm cov tshuab lossis lub cev.
01
Beneficiation classification
Cov granular quartz xuab zeb thiab hmoov bauxite tuaj yeem sib cais los ntawm kev ntxuav, sieving lossis grading txoj kev los txhim kho qhov zoo. Nws yog haum rau boehmite nrog siab silicon ntsiab lus.
02
Lub ntiajteb txawj nqus beneficiation
Kev siv cov txiaj ntsig hnyav nruab nrab tuaj yeem cais cov hlau uas muaj cov av nplaum liab hauv cov bauxite, thiab cov kauv concentrator tuaj yeem tshem tawm siderite thiab lwm yam ntxhia hnyav.
03
Sib nqus sib cais
Kev siv cov hlau nplaum sib nqus tsis muaj zog tuaj yeem tshem tawm cov hlau nplaum sib nqus hauv bauxite, thiab siv cov khoom sib nqus sib nqus muaj zog xws li phaj sib nqus sib nqus, lub nplhaib ntsug siab gradient sib nqus sib nqus, electromagnetic slurry sib nqus sib nqus cais tuaj yeem tshem tawm cov hlau oxide, titanium thiab hlau silicate, thiab lwm yam. Kev xaiv cov khoom siv hlau nplaum tsis muaj zog tuaj yeem ua rau cov ntsiab lus txhuas nce ntxiv thaum txo cov nqi ntawm alumina ntau lawm thiab ua.
04
Flotation
Rau sulfides xws li pyrite muaj nyob rau hauv bauxite, xanthate flotation yuav siv tau los tshem tawm; zoo thiab thim rov qab flotation kuj siv tau los tshem tawm impurities xws li pyrite, titanium, silicon, los yog xaiv AI2O3 cov ntsiab lus txog li 73% ntawm high-purity bauxite.
Ua 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 cov nqi qis, thiab cov khoom lag luam zoo. ). Rau bauxite nrog ib tug tsawg piv ntawm txhuas rau silicon, cov dej qab zib txiv qaub sintering txoj kev yog saws, thiab Bayer txoj kev thiab cov dej qab zib txiv qaub sintering txoj kev kuj yuav siv tau nyob rau hauv ib tug ua ke ntau lawm txheej txheem.
Kev tsim cov txhuas ntsev
Nrog bauxite, aluminium sulfate tuaj yeem tsim los ntawm txoj kev sulfuric acid, thiab polyaluminum chloride tuaj yeem tsim los ntawm kev kub-kub hydrochloric acid los nag.
