Iipropati zezimbiwa kunye nolwakhiwo lwezimbiwa
Iiminerali ezineTitanium ziquka i-ilmenite, i-rutile, i-anatase, i-brookite, i-perovskite, i-sphene, i-titanomagnetite, njl.njl., phakathi kwazo i-ilmenite kunye ne-rutile zezona ziminerali ziphambili zokunyibilikisa i-titanium.
Ifomula yemolekyuli ye-ilmenite yiFeTiO3, ngokwethiyori iqulethe i-52.66% yeTiO2 kunye ne-47.34% yeFeO. Yintsimbi engwevu ukuya kwemnyama, enobunzima be-Mohs obuyi-5-6, ubuninzi be-4.72g/cm3, imagnetism ephakathi, umqhubi olungileyo, kunye nohlobo oluqhelekileyo. Ubunikazi bomgangatho buxutywe ne-magnesium kunye ne-manganese, okanye buqulathe inclusions ze-hematite ezincinci.
Ifomula yemolekyuli yerutile yiTiO2, equlethe i-60% Ti kunye ne-40% O. Yiminerali ebomvu-mdaka, edla ngokuba nomxube wesinyithi, i-niobium, i-chromium, i-tantalum, i-tin, njl.njl., enobunzima be-Mohs obuyi-6, kunye noxinano lwe-4.2 ~ 4.3g / cm3. Imagnethi, ukuqhuba kakuhle, umdaka omnyama xa umxholo wesinyithi uphezulu, irutile iveliswa ikakhulu kwiindawo zokubeka.
Amasimi esicelo kunye nezalathisi zobugcisa
I-Rutile kunye ne-ilmenite zezona zinto ziphambili zokunyibilikisa i-titanium yentsimbi, ukuvelisa i-titanium dioxide, ii-welding rods, kunye ne-welding fluxes.

Itekhnoloji yokucubungula
Ngokwesiqhelo i-ilmenite kunye ne-rutile ore zihamba nezinye iiminerali ezahlukeneyo, ezifana ne-magnetite, i-hematite, i-quartz, i-feldspar, i-amphibole, i-olivine, i-garnet, i-chromite, i-apatite, i-mica, i-pyroxene. Amatye, njl.njl., akhethwa ngokubanzi ngokwahlukana komxhuzulane, ukwahlukana kwemagnethi, ukwahlukana kombane kunye nokuflotha.
Ukuphucula amandla omxhuzulane
Le ndlela isetyenziswa ngokubanzi ekuhlukaniseni okurhabaxa kwe-placer equlathe i-titanium okanye i-primary ore equlathe i-titanium ecoliweyo. Uxinano lweeminerali eziqulathe i-titanium ludla ngokuba ngaphezulu kwe-4g/cm3. Ke ngoko, uninzi lwee-gangues ezinoxinano olungaphantsi kwe-3g/cm3 zinokususwa ngokwahlulahlula amandla omhlaba. Ukususwa kweeminerali. Izixhobo zokwahlula amandla omhlaba ziquka i-jig, i-spiral concentrator, i-shaker, i-chute, njl.
Ukwahlulwa kwemagnethi
Indlela yokwahlula imagnethi isetyenziswa kakhulu ekukhetheni iiminerali ezinetitanium. Singasebenzisa ukwahlula imagnethi obuthathaka ukwahlula imagnethi, size sisebenzise ukwahlula imagnethi okunamandla ukwahlula i-ilmenite yemagnethi ephakathi. Umzekelo, i-concentrate ine-iron oxide engaphezulu okanye kwi-iron silicate, indlela yokwahlula i-gravity kufuneka isetyenziswe ukususa ukungcola okunobunzima obuncinci. Kwishishini, zombini ukwahlula imagnethi owomileyo nomanzi kuyasetyenziswa. Izixhobo zokwahlula imagnethi ziquka ikakhulu i-cylindrical magnetic separator, i-plate magnetic separator, i-vertical ring high gradient magnetic separator, njl.

I-magnetic plate enamandla aphezulu yokwahlulahlula
Ukuvuselelwa kwe-electrostatic
Ngokuyintloko isebenzisa umahluko kwi-conductivity phakathi kweeminerali ezahlukeneyo kwi-coarse concentrate equlethe i-titanium ekukhetheni, njengokwahlula i-rutile, i-zircon, kunye ne-monazite. Izixhobo zokwahlulahlula zombane ezisetyenziswayo ziluhlobo lwe-roller, uhlobo lweplate, uhlobo lweplate yesihluzo njalo njalo.
Ukudada
Isetyenziswa kakhulu ukwahlula i-ore ene-titanium ecolekileyo. Ii-reagents ze-flotation ezisetyenziswa rhoqo ziquka i-sulfuric acid, i-oyile ende, i-oleic acid, i-diesel oil kunye ne-emulsifiers. Iindlela zokuphucula ziquka i-titanium flotation entle kunye ne-reverse flotation yeeminerali ze-gangue.
Ukuzuza ngokudibeneyo
Kwi-placerite enezimbiwa ezinxulumeneyo ngakumbi, umahluko kwi-magnetic susceptibility ethile, i-density, i-conductivity, kunye ne-floating phakathi kwezimbiwa ungasetyenziselwa ukwahlula izimbiwa ngenkqubo edibeneyo "ye-magnetic, i-heavy, electric, kunye ne-floating". Umzekelo, isanti ye-alluvial yonxweme iqulethe izimbiwa ezifana ne-magnetite, i-ilmenite, i-rutile, isanti ye-zircon, i-monazite, isanti yolwandle, njl. Okokuqala, i-magnetite yahlulwe yi-weak magnetic field, kwaye emva koko i-ilmenite yahlulwe yi-vertical field ring enamandla aphakathi. I-high field strength vertical ring ye-vertical ring tailings isusa ezinye izimbiwa ezine-iron, kwaye emva koko i-small specific gravity yahlulwe ngendlela yokwahlula i-gravity. Kwisanti yolwandle, izimbiwa ezinzima yi-rutile kunye ne-zircon sand. I-rutile ene-conductivity engcono inokukhethwa ngokwahlula i-electric, ukuze kugqitywe ukwahlula i-gravity esebenzayo yolu hlobo lwezimbiwa.
