Mineral zog thiab ntxhia qauv
Titanium-bearing minerals mas muaj xws li ilmenite, rutile, anatase, brookite, perovskite, sphene, titanomagnetite, thiab lwm yam, ntawm cov ilmenite thiab rutile yog lub ntsiab titanium smelting minerals.
Cov mis mos molecular ntawm ilmenite yog FeTiO3, theoretically muaj 52.66% ntawm TiO2 thiab 47.34% ntawm FeO. Nws yog cov hlau grey rau dub ore, nrog rau Mohs hardness ntawm 5-6, qhov ceev ntawm 4.72g / cm3, nruab nrab hlau nplaum, zoo neeg xyuas pib, thiab ib txwm hom. Qhov zoo ntawm tus kheej yog sib xyaw nrog magnesium thiab manganese, los yog muaj cov nplua scaly hematite suav nrog.
Cov mis mos molecular ntawm rutile yog TiO2, muaj 60% Ti thiab 40% O. Nws yog xim av-liab ntxhia, feem ntau muaj cov sib xyaw ntawm hlau, niobium, chromium, tantalum, tin, thiab lwm yam, nrog rau Mohs hardness ntawm 6, thiab qhov ceev ntawm 4.2 ~ 4.3g / cm3. Magnetism, zoo conductivity, tsaus xim av thaum hlau cov ntsiab lus siab, rutile yog tsim nyob rau hauv placers.
Daim ntawv thov teb thiab kev ntsuas kev ntsuas
Rutile thiab ilmenite yog cov khoom siv tseem ceeb rau smelting metallic titanium, tsim titanium dioxide, vuam pas nrig, thiab vuam fluxes.

Kev siv tshuab
Feem ntau ilmenite thiab rutile ore yog nrog rau ntau yam ntawm lwm yam minerals, xws li magnetite, hematite, quartz, feldspar, amphibole, olivine, garnet, chromite, apatite, mica, pyroxene Pob zeb, thiab lwm yam, feem ntau xaiv los ntawm kev sib cais sib nqus, sib nqus. kev sib cais, hluav taws xob sib cais thiab flotation.
Lub ntiajteb txawj nqus beneficiation
Txoj kev no feem ntau yog siv rau kev sib cais ntawm titanium-muaj placer lossis crushed titanium-muaj thawj ore. Qhov ceev ntawm titanium-muaj cov minerals feem ntau yog ntau dua 4g / cm3. Yog li ntawd, feem ntau gangues nrog qhov ceev ntawm tsawg dua 3g / cm3 tuaj yeem raug tshem tawm los ntawm kev sib cais ntawm lub ntiajteb txawj nqus. Mineral tshem tawm. Cov khoom sib cais lub ntiajteb txawj nqus muaj xws li jig, kauv concentrator, shaker, chute, thiab lwm yam.
Sib nqus sib cais
Txoj kev sib nqus sib nqus yog siv dav hauv kev xaiv cov titanium-muaj cov zaub mov. Peb tuaj yeem siv tsis muaj zog sib nqus sib cais los cais cov hlau nplaum, thiab tom qab ntawd siv cov hlau nplaum sib nqus kom sib cais nruab nrab-magnetic ilmenite. Piv txwv li, cov concentrate muaj ntau cov hlau oxide lossis Rau cov hlau silicate, txoj kev sib cais ntawm lub ntiajteb txawj nqus yuav tsum tau siv los tshem tawm cov impurities nrog lub ntiajteb txawj nqus me me. Hauv kev lag luam, ob qho tib si qhuav thiab ntub sib nqus sib nqus yog siv.Magnetic sib cais cov cuab yeej feem ntau suav nrog cylindrical magnetic separator, phaj sib nqus sib nqus, ntsug nplhaib siab gradient sib nqus sib nqus, thiab lwm yam.
Nruas magnetic separator
High-intensity magnetic phaj magnetic separator
Electrostatic kev pab cuam
Nws tsuas yog siv qhov sib txawv ntawm qhov sib txawv ntawm cov ntxhia hauv cov titanium uas muaj ntxhib concentrate rau kev xaiv, xws li kev sib cais ntawm rutile, zircon, thiab monazite. Cov hluav taws xob sib cais siv yog cov menyuam hom, phaj hom, sieve phaj hom thiab lwm yam.
Flotation
Nws yog tsuas yog siv los cais cov nplua-grained titanium-muaj ore. Feem ntau siv flotation reagents muaj xws li sulfuric acid, siab roj, oleic acid, diesel roj thiab emulsifiers. Cov kev pab cuam muaj xws li zoo flotation ntawm titanium thiab rov qab flotation ntawm gangue minerals.
Kev sib koom ua ke
Rau cov placerite nrog cov ntxhia ntau dua, qhov sib txawv ntawm qhov tshwj xeeb sib nqus susceptibility, ntom, conductivity, thiab floatability ntawm cov zaub mov tuaj yeem siv los cais cov zaub mov los ntawm kev sib xyaw ua ke ntawm "sib nqus, hnyav, hluav taws xob, thiab ntab".Piv txwv li, ntug hiav txwv dej alluvial xuab zeb muaj cov minerals xws li magnetite, ilmenite, rutile, zircon xuab zeb, monazite, hiav txwv xuab zeb, thiab lwm yam. Ua ntej, lub magnetite yog sib cais los ntawm qaug zog magnetic teb, thiab ces lub ilmenite yog sib cais los ntawm ntsug nplhaib nrog nruab nrab lub zog. Lub siab lub zog ntsug lub nplhaib ntawm lub nplhaib ntsug tailings tshem tawm lwm yam hlau-cov kabmob, thiab tom qab ntawd qhov tshwj xeeb me me yog sib cais los ntawm txoj kev sib cais ntawm lub ntiajteb txawj nqus. Rau hiav txwv xuab zeb, cov ntxhia hnyav yog rutile thiab zircon xuab zeb. Lub rutile nrog zoo conductivity tuaj yeem raug xaiv los ntawm kev sib cais hluav taws xob, thiaj li ua kom tiav qhov kev sib cais zoo ntawm cov pob zeb no.
Ntiv nplhaib siab gradient sib nqus separator
Case kev pab
Muaj cov hlau nplaum, titanomagnetite, ilmenite, rutile, zircon xuab zeb, hiav txwv xuab zeb thiab ib qho me me ntawm cov hlau-cov pob zeb hauv cov pob zeb hauv pob zeb hauv Indonesia.,Ntawm lawv, ilmenite, rutile, thiab zircon xuab zeb yog lub hom phiaj tseem ceeb ntawm cov zaub mov, thiab titanomagnetite, hlau oxide, hlau silicate, thiab hiav txwv xuab zeb yog impurities.
