Kapangidwe ka mchere ndi kapangidwe ka mchere
Michere yokhala ndi titaniyamu imaphatikizapo ilmenite, rutile, anatase, brookite, perovskite, sphene, titanomagnetite, ndi zina zotero, zomwe ilmenite ndi rutile ndizomwe zimakhala mchere waukulu wosungunula titaniyamu.
Fomula ya molekyu ya ilmenite ndi FeTiO3, yomwe ili ndi 52.66% ya TiO2 ndi 47.34% ya FeO. Ndi miyala yachitsulo yoyera mpaka yakuda, yokhala ndi kuuma kwa Mohs kwa 5-6, kuchuluka kwa 4.72g/cm3, maginito apakatikati, woyendetsa wabwino, komanso mtundu wabwinobwino. Kudziwika kwabwino kumasakanizidwa ndi magnesium ndi manganese, kapena kumakhala ndi ma scaly hematite inclusions abwino.
Fomula ya rutile ya molekyulu ndi TiO2, yokhala ndi 60% Ti ndi 40% O. Ndi mchere wofiira wofiirira, nthawi zambiri umakhala ndi chisakanizo cha chitsulo, niobium, chromium, tantalum, tin, ndi zina zotero, wokhala ndi kuuma kwa Mohs kwa 6, ndi kuchuluka kwa 4.2 ~ 4.3g/cm3. Magnetism, conductivity yabwino, bulauni wakuda pamene chitsulo chili chochuluka, rutile imapangidwa makamaka mu placers.
Magawo ogwiritsira ntchito ndi zizindikiro zaukadaulo
Rutile ndi ilmenite ndi zinthu zazikulu zopangira titaniyamu yachitsulo, kupanga titanium dioxide, ndodo zolumikizira, ndi ma fluxes olumikizira.

Ukadaulo wokonza
Kawirikawiri miyala ya ilmenite ndi rutile imaphatikizidwa ndi mchere wina wosiyanasiyana, monga magnetite, hematite, quartz, feldspar, amphibole, olivine, garnet, chromite, apatite, mica, pyroxene. Miyala, ndi zina zotero, nthawi zambiri imasankhidwa ndi kulekanitsa mphamvu yokoka, kulekanitsa maginito, kulekanitsa magetsi ndi kuyandama.
Kupindula kwa mphamvu yokoka
Njira imeneyi nthawi zambiri imagwiritsidwa ntchito polekanitsa miyala yamtengo wapatali yokhala ndi titaniyamu kapena miyala yamtengo wapatali yokhala ndi titaniyamu yophwanyidwa. Kuchuluka kwa mchere wokhala ndi titaniyamu nthawi zambiri kumakhala kokulirapo kuposa 4g/cm3. Chifukwa chake, ma gangues ambiri okhala ndi kuchulukira kwa 3g/cm3 amatha kuchotsedwa polekanitsa miyala yamtengo wapatali. Kuchotsa mchere. Zipangizo zolekanitsa mphamvu yokoka zimaphatikizapo jig, spiral concentrator, shaker, chute, ndi zina zotero.
Kulekanitsa maginito
Njira yolekanitsa maginito imagwiritsidwa ntchito kwambiri posankha mchere wokhala ndi titaniyamu. Tingagwiritse ntchito kulekanitsa maginito kofooka kuti tilekanitse maginito, kenako tigwiritse ntchito kulekanitsa maginito kolimba kuti tilekanitse ilmenite yapakati-maginito. Mwachitsanzo, concentrate imakhala ndi iron oxide yambiri kapena Pa chitsulo silicate, njira yolekanitsa mphamvu yokoka iyenera kugwiritsidwa ntchito kuchotsa zonyansa ndi mphamvu yokoka yaying'ono. M'mafakitale, njira yolekanitsa maginito youma komanso yonyowa imagwiritsidwa ntchito. Zipangizo zolekanitsa maginito zimaphatikizapo cylindrical magnetic separator, plate magnetic separator, vertical ring high gradient magnetic separator, ndi zina zotero.
Cholekanitsa maginito a ng'oma
Maginito olekanitsa maginito amphamvu kwambiri
Kupatsa mphamvu zamagetsi
Imagwiritsa ntchito makamaka kusiyana kwa conductivity pakati pa mchere wosiyanasiyana mu titaniyamu yolimba kwambiri posankha, monga kulekanitsa rutile, zircon, ndi monazite. Zolekanitsa zamagetsi zomwe zimagwiritsidwa ntchito ndi mtundu wa roller, mtundu wa mbale, mtundu wa sieve plate ndi zina zotero.
Kuyandama
Amagwiritsidwa ntchito makamaka kulekanitsa miyala yamtengo wapatali yokhala ndi titaniyamu. Zinthu zomwe zimagwiritsidwa ntchito kwambiri poyatsa nthaka ndi monga sulfuric acid, mafuta aatali, oleic acid, mafuta a dizilo ndi ma emulsifiers. Njira zophikira nthaka zimaphatikizapo kuyandama kwa titaniyamu ndi kuyandama kwa miyala ya gangue.
Kupindula pamodzi
Pa placerite yokhala ndi mchere wogwirizana kwambiri, kusiyana kwa mphamvu ya maginito, kuchulukana, kuyendetsa, ndi kuyandama pakati pa mchere kungagwiritsidwe ntchito kulekanitsa mchere pogwiritsa ntchito njira yophatikizana ya "maginito, kulemera, magetsi, ndi kuyandama". Mwachitsanzo, mchenga wa m'mphepete mwa nyanja uli ndi mchere monga magnetite, ilmenite, rutile, mchenga wa zircon, monazite, mchenga wa m'nyanja, ndi zina zotero. Choyamba, magnetite imalekanitsidwa ndi mphamvu yofooka ya maginito, kenako ilmenite imalekanitsidwa ndi mphete yoyima yokhala ndi mphamvu yapakatikati. Mphete yoyima yamphamvu kwambiri ya mphete yoyima imachotsa mchere wina wokhala ndi chitsulo, kenako mphamvu yaying'ono yeniyeni imalekanitsidwa ndi njira yolekanitsira mphamvu yokoka. Pa mchenga wa m'nyanja, mchere wolemera ndi rutile ndi mchenga wa zircon. Rutile yokhala ndi mphamvu yabwino yoyendetsera zinthu imatha kusankhidwa ndi kulekanitsa kwamagetsi, kuti ikwaniritse kulekanitsa kogwira mtima kwa mchere wamtunduwu.
Cholekanitsa maginito cha mphete yopingasa yokhala ndi maginito okwera kwambiri
Nkhani yokhudza phindu
Pali magnetite, titanomagnetite, ilmenite, rutile, mchenga wa zircon, mchenga wa m'nyanja ndi mchere wochepa wokhala ndi chitsulo m'malo osungiramo zinthu ku Indonesia.，Pakati pawo, ilmenite, rutile, ndi mchenga wa zircon ndiye mchere waukulu womwe umayang'aniridwa, ndipo titanomagnetite, iron oxide, iron silicate, ndi mchenga wa m'nyanja ndi zinthu zodetsedwa. Michereyo imalekanitsidwa ndi kuyesedwa pogwiritsa ntchito njira zakuthupi monga kulekanitsa maginito ndi kulekanitsa mphamvu yokoka. Zinthu zonse zosakanikirana. Pakati pawo ilmenite, rutile, zircon ndi mchere waukulu womwe umayang'aniridwa, ilmenite, iron oxide, iron silicate, mchenga wa m'nyanja ngati zinthu zodetsedwa, Kudzera mu kulekanitsa maginito, kulekanitsa mphamvu yokoka ndi njira zina zakuthupi, mcherewo umalekanitsidwa ndipo zinthu zosakanikirana zoyenera zimasankhidwa.
Kukula kwa tinthu ta mchenga wa alluvial ndi kofanana, ndipo kukula kwa tinthu tambiri ndi 0.03 ~ 0.85 mm. Zinthu zoyenerera monga ilmenite, rutile ndi mchenga wa zircon zimalekanitsidwa ndi njira yophatikizana yopangira maginito ofooka + kulekanitsa kwa maginito apakati + kulekanitsa kwa maginito okwera + kulekanitsa mphamvu yokoka.
- Chizindikiro cha ubwino chikuwonetsedwa mu Table 4.
Chithunzi 1. Njira yoyesera kuphatikiza mchere wa mchenga
Gome 4. Ma Index a Mayeso Othandizira Ogwirizana
Pogwiritsa ntchito kusiyana kwa mphamvu yeniyeni ya maginito ndi kuchulukana pakati pa mchere, kudzera mu njira yophatikizana ya kugawanika kwa mphamvu ya maginito yofooka + yamphamvu ya maginito + yokoka, ma ilmenite concentrates okhala ndi phindu la 25.37%, TiO2 grade ya 46.39%, ndi kuchira kwa 60.83% adasankhidwa. Rutile concentrate yokhala ndi phindu la 8.52%, TiO2 grade ya 66.15% ndi kuchira kwa 29.15%; Zircon placer concentrate yokhala ndi phindu la 40.15%, ZrO2 grade ya 58.06%, ndi kuchira kwa 89.41%. Iron concentrate ili ndi titanomagnetite yambiri, kotero zinthu zoyenera zachitsulo sizingasankhidwe.
