Mchere katundu ndi mchere kapangidwe
Mchere wokhala ndi titaniyamu makamaka umaphatikizapo ilmenite, rutile, anatase, brookite, perovskite, sphene, titanomagnetite, ndi zina zotero, zomwe ilmenite ndi rutile ndi mchere waukulu wa titaniyamu wosungunuka.
Mapangidwe a molekyulu a ilmenite ndi FeTiO3, mongoyerekeza ali ndi 52.66% ya TiO2 ndi 47.34% ya FeO. Ndichitsulo chotuwa chotuwa mpaka chitsulo chakuda, cholimba cha Mohs cha 5-6, kachulukidwe ka 4.72g/cm3, maginito apakatikati, kondakitala wabwino, ndi mtundu wamba. Chidziwitso chodziwika bwino chimasakanizidwa ndi magnesium ndi manganese, kapena chimakhala ndi ma scaly hematite inclusions.
Mamolekyu a rutile ndi TiO2, omwe ali ndi 60% Ti ndi 40% O. Ndi mchere wofiirira wofiirira, nthawi zambiri amakhala ndi chitsulo, niobium, chromium, tantalum, tin, ndi zina zotero, ndi kuuma kwa Mohs kwa 6, ndi kachulukidwe wa 4.2 ~ 4.3g/cm3. Magnetism, ma conductivity abwino, bulauni wakuda pamene chitsulo chili chochuluka, rutile amapangidwa makamaka mu placers.
Minda yofunsira ndi zizindikiro zaukadaulo
Rutile ndi ilmenite ndizomwe zimagwiritsidwa ntchito posungunula zitsulo za titaniyamu, kupanga titaniyamu woipa, ndodo zowotcherera, ndi zowotcherera.

Processing luso
Kawirikawiri ilmenite ndi rutile ore amatsagana ndi mitundu yosiyanasiyana ya mchere, monga magnetite, hematite, quartz, feldspar, amphibole, olivine, garnet, chromite, apatite, mica, pyroxene Stones, etc. kulekanitsa, kulekanitsa magetsi ndi kuyandama.
Mphamvu yokoka
Njira imeneyi nthawi zambiri imagwiritsidwa ntchito polekanitsa movutirapo nkhokwe yokhala ndi titaniyamu kapena wophwanyidwa wokhala ndi titaniyamu woyambira. Kachulukidwe ka mchere wokhala ndi titaniyamu nthawi zambiri ndi wamkulu kuposa 4g/cm3. Choncho, ma gangues ambiri omwe ali ndi mphamvu zosachepera 3g / cm3 akhoza kuchotsedwa ndi kulekanitsa mphamvu yokoka. Kuchotsa mchere. Zida zolekanitsa mphamvu yokoka zimaphatikizapo jig, spiral concentrator, shaker, chute, etc.
Kupatukana kwa maginito
Njira yolekanitsa maginito imagwiritsidwa ntchito kwambiri posankha mchere wokhala ndi titaniyamu. Titha kugwiritsa ntchito kulekanitsa ofooka maginito kulekanitsa magnetite, ndiyeno ntchito mphamvu maginito kulekana kulekanitsa sing'anga-maginito ilmenite. Mwachitsanzo, chigawocho chimakhala ndi okusayidi yachitsulo kapena Kwachitsulo cha silicate, njira yolekanitsa mphamvu yokoka iyenera kugwiritsidwa ntchito kuchotsa zonyansa ndi mphamvu yokoka yaing'ono. Mu makampani, onse youma ndi chonyowa maginito kulekana are used.Maginito kupatukana zida makamaka monga cylindrical maginito olekanitsa, mbale maginito olekanitsa, ofukula mphete mkulu gradient maginito olekanitsa, etc.
Drum magnetic separator
High-mphamvu maginito mbale maginito olekanitsa
Electrostatic Beneficiation
Amagwiritsa ntchito kwambiri kusiyana kwa ma conductivity pakati pa mchere wosiyanasiyana mu titaniyamu wokhala ndi coarse concentrate posankha, monga kulekanitsa rutile, zircon, ndi monazite. Olekanitsa magetsi omwe amagwiritsidwa ntchito ndi mtundu wa roller, mtundu wa mbale, mtundu wa mbale ya sieve ndi zina zotero.
Kuyandama
Amagwiritsidwa ntchito makamaka kulekanitsa miyala ya titaniyamu yokhala ndi titaniyamu yabwino. Ma reagents oyandama omwe amagwiritsidwa ntchito kwambiri ndi sulfuric acid, mafuta amtali, oleic acid, mafuta a dizilo ndi emulsifiers. Njira zopindulira zikuphatikiza kuyandama kwabwino kwa titaniyamu ndi kuyandama mobwerera kwa mchere wa gangue.
Kupindula pamodzi
Kwa placerite ndi mchere wogwirizana kwambiri, kusiyana kwapadera kwa maginito, kachulukidwe, kayendedwe ka kayendedwe kake, ndi kuyandama pakati pa mchere kungagwiritsidwe ntchito kulekanitsa mchere ndi njira yophatikizana ya "magnetic, heavy, electric, and float" .Mwachitsanzo, m'mphepete mwa nyanja mchenga wa alluvial uli ndi mchere monga magnetite, ilmenite, rutile, mchenga wa zircon, monazite, mchenga wa m'nyanja, etc.Choyamba, magnetite imasiyanitsidwa ndi mphamvu ya maginito yofooka, ndiyeno ilmenite imasiyanitsidwa ndi mphete yowongoka ndi mphamvu yapakati pamunda. Mphete yamphamvu yam'munda yam'mphepete mwake imachotsa mchere wina wokhala ndi chitsulo, ndiyeno mphamvu yokoka yaying'ono imasiyanitsidwa ndi njira yolekanitsa mphamvu yokoka. Kwa mchenga wa m'nyanja, mchere wolemera ndi rutile ndi mchenga wa zircon. The rutile ndi conductivity bwino akhoza kusankhidwa ndi kulekanitsa magetsi, kuti amalize kulekanitsa bwino kwa mtundu uwu wa mchere.
Choyimira mphete chapamwamba cha maginito olekanitsa
Beneficiation kesi
Pali magnetite, titanomagnetite, ilmenite, rutile, mchenga wa zircon, mchenga wa m'nyanja ndi mchere wochepa wokhala ndi chitsulo m'mafakitale a alluvial ku Indonesia.,Pakati pawo, mchenga wa ilmenite, rutile, ndi zircon ndizomwe zimafunikira mchere, ndipo titanomagnetite, iron oxide, iron silicate, ndi mchenga wa m'nyanja ndi zonyansa. Mcherewo umasiyanitsidwa ndikuyeneretsedwa ndi njira zakuthupi monga kulekanitsa maginito ndi kulekanitsa mphamvu yokoka. Pakati pawo ilmenite, rutile, zircon ndizomwe zimafunikira mchere, ilmenite, iron oxide, iron silicate, mchenga wa m'nyanja ngati zonyansa, Kupyolera mu kupatukana kwa maginito, kulekanitsa mphamvu yokoka ndi njira zina zakuthupi, mcherewo umalekanitsidwa ndipo zinthu zoyenerera zimayikidwa. osankhidwa.
The tinthu kukula kwa alluvial mchenga ndi yunifolomu, ndipo ambiri tinthu kukula ndi 0.03 ~ 0.85 mm. Zinthu zokhazikika zokhazikika monga ilmenite, rutile ndi mchenga wa zircon zimasiyanitsidwa ndi njira yophatikizira yophatikizika ya kulekanitsa kofooka kwa maginito + kupatukana kwapakati pa maginito + kupatukana kwakukulu kwa maginito + kulekanitsa mphamvu yokoka.
- Beneficiation index ikuwonetsedwa mu Table 4.
