Mineral properties uye mineral structure
Titanium-inotakura zvicherwa zvinonyanya zvinosanganisira ilmenite, rutile, anatase, brookite, perovskite, sphene, titanomagnetite, nezvimwewo, pakati peiyo ilmenite uye rutile ndiyo huru titanium inonyungudutsa zvicherwa.
Iyo molecular formula ye ilmenite ndeye FeTiO3, inoretically ine 52.66% yeTiO2 uye 47.34% yeFeO. Iyo isimbi yegrey kune nhema ore, ine Mohs kuoma kwe5-6, density ye4.72g/cm3, yepakati magineti, yakanaka conductor, uye yakajairika mhando. Hunhu hwehunhu hwakasanganiswa ne magnesium uye manganese, kana ine yakanaka scaly hematite inclusions.
Iyo molecular formula ye rutile ndeye TiO2, ine 60% Ti uye 40% O. Iine brownish-tsvuku mineral mineral, kazhinji ine musanganiswa wesimbi, niobium, chromium, tantalum, tin, nezvimwewo, ine Mohs yakaoma ye6, uye kuwanda kwe4.2 ~ 4.3g/cm3. Magnetism, yakanaka conductivity, yakasviba yakasviba kana iron yemukati yakakwira, rutile inonyanya kugadzirwa mune placers.
Minda yekushandisa uye zviratidzo zvehunyanzvi
Rutile uye ilmenite ndiwo makuru emidziyo yekunyungudutsa simbi titanium, kugadzira titanium dioxide, welding rods, uye welding fluxes.

Processing tekinoroji
Kazhinji ilmenite uye rutile ore inoperekedzwa nemamwe akasiyana emaminerari, akadai semagnetite, hematite, quartz, feldspar, amphibole, olivine, garnet, chromite, apatite, mica, pyroxene Matombo, nezvimwewo, anowanzo kusarudzwa nekuparadzaniswa kwegiravhiti, magineti. kuparadzaniswa, kupatsanurwa kwemagetsi uye flotation.
Gravity Beneficiation
Iyi nzira inowanzo shandiswa kupatsanurwa kwakashata kwetitanium-ine placer kana yakapwanyika titanium-ine primary ore. Kuwanda kwemaminerari ane titanium anowanzo pfuura 4g/cm3. Nokudaro, ma gangues akawanda ane density isingasviki 3g/cm3 anogona kubviswa negiravhiti kupatsanurwa. Mineral kubvisa. Magetsi ekuparadzanisa michina inosanganisira jig, spiral concentrator, shaker, chute, nezvimwe.
Magnetic kupatsanurwa
Iyo magnetic separation method inoshandiswa zvakanyanya mukusarudzwa kwetitanium-ine minerals. Isu tinogona kushandisa isina simba remagineti kupatsanura kuparadzanisa magnetite, uye toshandisa yakasimba magineti kupatsanura kuparadzanisa yepakati-magineti ilmenite. Semuenzaniso, iyo concentrate ine yakawanda iron oxide kana Yesimbi silicate, iyo giravhiti yekuparadzanisa nzira inofanira kushandiswa kubvisa tsvina ine diki chaiyo giravhiti. Muindasitiri, ese ari maviri akaoma uye akanyorova magineti separation anoshandiswa.Magnetic yekuparadzanisa michina inonyanya kusanganisira cylindrical magineti separator, ndiro yemagineti separator, vertical ring high gradient magineti separator, nezvimwe.

Electrostatic Beneficiation
Iyo inonyanya kushandisa mutsauko mukufambiswa pakati pezvicherwa zvakasiyana mune titanium-ine coarse concentrate yekusarudza, sekuparadzaniswa kwerutile, zircon, uye monazite. Iwo emagetsi separators anoshandiswa ari roller type, plate type, sieve plate type zvichingodaro.
Flotation
Inonyanya kushandiswa kuparadzanisa yakanaka-grained titanium-ine ore. Anowanzo shandiswa flotation reagents anosanganisira sulfuric acid, mafuta akareba, oleic acid, mafuta edhiziri uye emulsifiers. Nzira dzekubatsira dzinosanganisira kutenderera kwakanaka kwetitanium uye kudzoreredza kutenderera kwemaminerari e gangue.
Joint beneficiation
Kune placerite ine mamwe maminerari ane hukama, mutsauko mune chaiwo magineti susceptibility, density, conductivity, uye floatability pakati pezvicherwa zvinogona kushandiswa kupatsanura zvicherwa nenzira yakasanganiswa ye "magnetic, inorema, yemagetsi, uye kuyangarara".Semuenzaniso, mahombekombe egungwa alluvial jecha rine zvicherwa zvakadai semagineti, ilmenite, rutile, zircon jecha, monazite, jecha regungwa, etc.Kutanga, magnetite inoparadzaniswa nemagetsi asina simba, uye ipapo ilmenite inoparadzaniswa nemhete yakadzika ine simba repakati pemunda. Iyo yakakwirira yemunda simba vertical mhete ye vertical ring tailings inobvisa mamwe maminera ane simbi, uye ipapo iyo diki chaiyo giravhiti inoparadzaniswa negiravhiti yekuparadzanisa nzira. Kune jecha regungwa, iyo inorema zvicherwa ndeye rutile uye zircon jecha. Iyo rutile ine conductivity iri nani inogona kusarudzwa nekuparadzaniswa kwemagetsi, kuitira kuti ipedze kuparadzaniswa kunobudirira kwemhando iyi yemaminerari.
