Kev siv tshuab ua khoom
Feem ntau ilmenite thiab rutile ore yog nrog los ntawm ntau yam minerals, xws li magnetite, hematite, quartz, feldspar, amphibole, olivine, garnet, chromite, apatite, mica, pyroxene. Cov pob zeb, thiab lwm yam, feem ntau yog xaiv los ntawm kev sib cais ntawm lub ntiajteb txawj nqus, kev sib cais sib nqus, kev sib cais hluav taws xob thiab kev ntab.
Kev pab txhawb nqa lub ntiajteb txawj nqus
Txoj kev no feem ntau yog siv rau kev sib cais ntawm cov titanium-muaj placer lossis cov titanium-muaj thawj ore. Qhov ceev ntawm cov titanium-muaj cov zaub mov feem ntau ntau dua 4g / cm3. Yog li ntawd, feem ntau gangues nrog qhov ceev tsawg dua 3g / cm3 tuaj yeem tshem tawm los ntawm kev sib cais lub ntiajteb txawj nqus. Kev tshem tawm cov zaub mov. Cov khoom siv sib cais lub ntiajteb txawj nqus suav nrog jig, spiral concentrator, shaker, chute, thiab lwm yam.
Kev sib cais sib nqus
Txoj kev sib cais sib nqus yog siv dav hauv kev xaiv cov zaub mov uas muaj titanium. Peb tuaj yeem siv kev sib cais sib nqus tsis muaj zog los cais cov magnetite, thiab tom qab ntawd siv kev sib cais sib nqus muaj zog los cais cov hlau nplaum nruab nrab ilmenite. Piv txwv li, cov khoom sib xyaw muaj ntau hlau oxide lossis Rau cov hlau silicate, txoj kev sib cais lub ntiajteb txawj nqus yuav tsum tau siv los tshem tawm cov khoom tsis huv nrog lub ntiajteb txawj nqus me me. Hauv kev lag luam, ob qho tib si qhuav thiab ntub sib cais sib nqus siv. Cov khoom siv sib cais sib nqus feem ntau suav nrog cylindrical sib cais sib nqus, phaj sib cais sib nqus, lub nplhaib ntsug siab gradient sib nqus, thiab lwm yam.
Lub nruas sib nqus sib cais
Cov phaj sib nqus sib nqus siab siv hluav taws xob ntau
Kev siv hluav taws xob electrostatic
Nws feem ntau siv qhov sib txawv ntawm kev coj ua ntawm cov zaub mov sib txawv hauv cov titanium-muaj cov khoom sib xyaw rau kev xaiv, xws li kev sib cais ntawm rutile, zircon, thiab monazite. Cov khoom sib cais hluav taws xob siv yog hom menyuam, hom phaj, hom phaj sieve thiab lwm yam.
Kev ntab dej
Nws yog siv los cais cov hlau uas muaj cov titanium zoo. Cov tshuaj reagents flotation feem ntau siv suav nrog sulfuric acid, roj siab, oleic acid, roj diesel thiab emulsifiers. Cov txheej txheem beneficiation suav nrog kev flotation zoo ntawm titanium thiab rov qab flotation ntawm cov zaub mov gangue.
Kev sib koom tes ua ke
Rau placerite nrog ntau cov minerals cuam tshuam, qhov sib txawv ntawm qhov tshwj xeeb magnetic susceptibility, density, conductivity, thiab floatability ntawm cov minerals tuaj yeem siv los cais cov minerals los ntawm kev sib xyaw ua ke ntawm "magnetic, heavy, electric, thiab float". Piv txwv li, cov xuab zeb ntug dej hiav txwv alluvial muaj cov minerals xws li magnetite, ilmenite, rutile, zircon xuab zeb, monazite, xuab zeb hiav txwv, thiab lwm yam. Ua ntej, magnetite raug sib cais los ntawm lub zog magnetic tsis muaj zog, thiab tom qab ntawd ilmenite raug sib cais los ntawm lub nplhaib ntsug nrog lub zog nruab nrab. Lub zog siab ntawm lub nplhaib ntsug tailings tshem tawm lwm cov minerals uas muaj hlau, thiab tom qab ntawd qhov hnyav tshwj xeeb me dua raug sib cais los ntawm txoj kev sib cais lub zog. Rau cov xuab zeb hiav txwv, cov minerals hnyav yog rutile thiab zircon xuab zeb. Rutile nrog conductivity zoo dua tuaj yeem xaiv los ntawm kev sib cais hluav taws xob, yog li ua kom tiav qhov kev sib cais zoo ntawm cov minerals no.
