Muaj pes tsawg leeg, tshwm sim thiab muaj daim ntawv thov ntawm Titanomagnetite
Titanomagnetite yog ib qho tseem ceeb tshaj plaws hauv cov zaub mov. Nws yog feem ntau tsim nyob rau hauv lub hauv paus los yog ultrabasic pob zeb lub cev thiab muaj ntau yam minerals, xws li titanium, hlau, chromium oxides, ntau yam silicate minerals, thiab ib tug me me ntawm leej faj, compounds ntawm arsenic, thiab phosphate minerals. Titanium magnetite muaj cov ntxhia sib txawv. Ilmenite thiab titanium magnetite yog cov muaj txiaj ntsig zoo tshaj plaws hauv cov ore. Dab tsi ntxiv, nws kuj tseem muaj cov hlau nplaum, hematite thiab sulfide.
Qhov xwm txheej ntawm titanium magnetite feem ntau yog phaj-muab thiab columnar ilmenite thiab ntaub tsim ilmenite precious pob zeb implanted nyob rau hauv magnetite nplej, thiab nws cov khoom zoo li magnetite. Cov ntxhia no muaj txiaj ntsig tseem ceeb hauv kev lag luam thiab feem ntau yog tsim nyob rau hauv magma deposits. Nws yog thawj cov khoom siv ntxhia rau kev ua kom zoo nkauj hlau titanium thiab hlau, thiab feem ntau yog siv los tsim daim txhuam cev titanium thiab titanium dioxide.
Nyob rau hauv cov nqe lus ntawm nws cov tshuaj muaj pes tsawg leeg, titanium magnetite yog hu ua ilmenite thaum TiO2 cov ntsiab lus ntau dua los yog sib npaug rau 25%, thaum titanium magnetite raug xa mus rau raws li muaj TiO2 cov ntsiab lus tsawg dua 25%. Nws yog hu ua vanadium-titanium magnetite yog tias nws muaj titanium ntxiv thiab vanadium. Titanomagnetite thiab vanadium-titanium magnetite qauv tsim muaj zog ntawm qhov kub thiab txias, thiab tawg thaum kub poob. Nyob rau hauv qhov kho qhov muag ntu, nws zoo heev yuav pom tau hais tias me me kev taw qhia kev sib tshuam ntawm ilmenite hauv cov nplej magnetite feem ntau nthuav dav raws octahedral so ntawm magnetite, uas yog hu ua ilmenite-hlau magnetite.
titanium magnetite hlau muaj ib tug muaj zog txheej txheem disintegration qauv. Feem ntau ntawm nws cov minerals yog gangue, nrog magnetite Fe3O4 thiab ilmenite FeTiO3 tejzaum nws kuj muaj ib tug me me ntawm hematite Fe2O3. Vanadium tseem ceeb muaj nyob hauv magnetite li V3+ los hloov ib feem ntawm Fe3+. Cov khoom ntawm vanadium oxide V2O3 nyob rau hauv cov ntxhia yog los ntawm thiab loj 0.2-0.4%, thiab ob peb hlau muaj ntau dua cov khoom ntawm 1. Cov qib hlau muaj li ntawm 15 mus rau 55 feem pua, thiab cov ntsiab lus TiO2 nyob ntawm 15 mus rau 25 feem pua.
Titanium magnetite muaj nyob hauv ntau qhov chaw thoob plaws ntiaj teb, feem ntau hauv Suav teb, Russia, South Africa, Tebchaws Meskas, Canada, Norway, Finland, Sweden, India, Australia, thiab New Zealand. Vanadium-titanium magnetite deposit nyob rau hauv Panzhihua, Sichuan, uas yog ib tug ntawm lub ntiaj teb no tus paub zoo tshaj plaws ilmenite ntau lawm cheeb tsam, muaj ilmenite reserves tseem ceeb nyob rau hauv Tuam Tshoj. Lub hom phiaj tseem ceeb ntawm cov khoom siv hlau hlau hauv Sichuan yog vanadium-titanium magnetite deposits, uas yog ib feem ntawm lub magmatic deposits lig. Cov khw muag khoom sawv cev ntau dua 85% ntawm cov khw muag khoom hlau tsis muaj hlau nyob hauv cheeb tsam, qhov thib peb hauv lub teb chaws cov khw muag khoom hlau hlau.
Technology rau titanium magnetite beneficiation thiab smelting yog tas li evolving. Feem ntau, sib nqus sib nqus yog siv los cais cov vanadium-titanium magnetite mloog zoo, nrog titanium magnetite ua tus thawj cov khoom rov qab. Flotation, lub ntiajteb txawj nqus sib cais, muaj zog sib nqus sib cais, lub ntiajteb txawj nqus sib cais, flotation, thiab lwm yam txheej txheem yog siv los rov qab ilmenite los ntawm tailings los tsim ilmenite concentrate. Flotation feem ntau yog siv los rov qab cov sulfur hauv cov txheej txheem xaiv hlau. Qhov zoo ntawm vanadium-hlau magnetite concentrate yog feem ntau siv rau kev rho tawm ntawm hlau thiab vanadium; Cov hlau ore concentrate feem ntau yog siv rau kev tsim cov sponge titanium thiab titanium dioxide; sulfide concentrate feem ntau yog siv rau kev rov qab los ntawm cobalt, npib tsib xee, thiab lawv cov oxides; thiab cov txheej txheem ntawm kev rov qab cov hlau thiab vanadium kuj ua rau rov qab cov ntsiab lus tseem ceeb xws li scandium thiab gallium.
