Liminerale tsa Kyanite li kenyelletsa kyanite, andalusite, le sillimanite. Tse tharo ke mefuta e fapaneng ea homogeneous le multiphase, 'me foromo ea lik'hemik'hale ke AI2SlO5, e nang le AI2O362.93% le SiO237.07%. Liminerale tsa Kyanite li na le refractoriness e phahameng, botsitso ba lik'hemik'hale le matla a mochine. Ke lisebelisoa tse tala tsa lisebelisoa tsa boleng bo phahameng ba refractory 'me li sebelisoa haholo ha ho etsoa thepa ea refractory, li-ceramics tse tsoetseng pele, li-alloys tsa aluminium-silicon le likhoele tse refractory.
Thepa ea Ore le Sebopeho sa Liminerale
Likristale tsa Kyanite li na le columnar e sephara, e putsoa kapa e putsoa-grey, vitreous le perela. Boima ba tataiso ea katoloso ea kristale e tšoanang ke 5.5, 'me boima ba tataiso ea katoloso ea kristale ea perpendicular ke 6.5 ho 7, kahoo e bitsoa "majoe a mabeli a thata",' me boima ke 3.56 ho 3.68g / cm3. Likarolo tse ka sehloohong ke kyanite le palo e nyane ea sillimanite.
Likristale tsa Andalusite li na le li-columnar, tse batlang li le lisekoere karolong ea sefapano, 'me li hlophisitsoe ka sebopeho se tloaelehileng sa sefapano karolong ea sefapano. 3.2g/cm3.
Likristale tsa Sillimanite li tšoana le nale, hangata li-radial le fibrous aggregates, grey-brown kapa gray-green, vitreous, 7 hardness, le 3.23-3.27g / cm3 density.
Liminerale tsa sehlopha sa Kyanite li fetoloa motsoako oa mullite (eo hape e tsejoang e le mullite) le silica (cristobalite) holim'a calcination ka mocheso o phahameng, 'me e fetela katoloso ea molumo. Liminerale tse amanang le tsona li kenyelletsa biotite, muscovite, sericite, quartz, graphite, plagioclase, garnet, rutile, pyrite, chlorite le liminerale tse ling.
Libaka tsa kopo le matšoao a theknoloji
Lisebelisoa tsa refractory ke masimo a mantlha a kopo ea liminerale tsa kyanite, tse ka sebelisetsoang ho etsa litene, ho ntlafatsa ts'ebetso e phahameng ea mocheso oa lihlahisoa tse hananang, ho kopanya mullite ka mocheso o phahameng, 'me kyanite e hlakileng le e hlakileng e ka sebelisoa e le mahakoe kapa mesebetsi ea matsoho.
Tšebeliso ea mantlha ea liminerale tsa kyanite:
| Sebaka sa kopo | Kopo e ka sehloohong |
| Refractory | Ho etsa litene tsa refractory, ho ntlafatsa litene tse hanyetsanang le mocheso o phahameng, lisebelisoa tse sa tsitsang tse se nang sebōpeho |
| Li-ceramics | Li-Ceramics tse tsoetseng pele, li-Ceramics tsa Theknoloji |
| Metallurgy | Matla a phahameng a silicon alloy alloy |
| Refractory fiber | Refractory line, spark plug lening insulator |
| lehakoe | Granularity ea Crystal, e khanyang ebile e pepenene joalo ka lisebelisoa tse tala bakeng sa mahakoe |
| Moriana | Ho etsoa ha meno a maiketsetso, aggregate bakeng sa lipoleiti tse hokahaneng tsa masapo a robehileng |
| Lik'hemik'hale | Mocheso o phahameng oa ho sebetsa mullite, thepa e hanyetsanang le acid, tube e lekanyang mocheso o phahameng |
Ka lebaka la liphapang tsa ts'ebetso ea lisebelisoa tse fapaneng tse tala tsa liminerale, ts'ebeliso le maemo a ts'ebetso ea kopo, ho na le litlhoko tse fapaneng bakeng sa boleng ba li-kyanite concentrates.
Theknoloji ea ho sebetsa - molemo le tlhoekiso
Mokhoa oa ho rua molemo le mokhoa oa theknoloji oa liminerale tsa kyanite haholo-holo o itšetlehile ka litšobotsi tse kenyelletsoeng tsa liminerale, ka kakaretso ho phaphamala, karohano ea matla a khoheli le karohano ea makenete, joalo-joalo.
① Ho phaphamala
Flotation ke mokhoa o ka sehloohong oa ho rua molemo bakeng sa liminerale tsa kyanite, empa ka kakaretso e hloka ho kopanngoa le mekhoa e meng ho fihlela litlhoko tsa matšoao a indasteri. Gravity desliming kapa flotation ka mor'a karohano ea makenete hangata e sebelisoa. Babokelli ba sebelisa mafura a acids le matsoai a bona, a sa nke lehlakore kapa a fokolang acidic pulp PH boleng, lintlha tse ka sehloohong tse susumetsang ke ho sila hantle, thepa e sa hloekang, phello ea desliming, tsamaiso ea lik'hemik'hale le pulp PH bohlokoa.
②Khetha hape
Bakeng sa liminerale tsa kyanite tse mahoashe tse khabisitsoeng le tse tsoakiloeng, mokhoa oa karohano ea matla a khoheli o sebelisoa haholo, 'me thepa ea karohano ea matla a khoheli e kenyelletsa tafole e sisinyehang, leholiotsoana, sehare se boima le chute ea spiral.
③Mokhoa oa karohano oa makenete
Ke mokhoa oa bohlokoahali oa ho rua molemo oa kyanite. Ka kakaretso e sebelisoa bakeng sa ho lokisa lisebelisoa tse tala tse khethiloeng ho khutlisa kapa ho tlosa lihlahisoa tsa makenete, kapa bakeng sa ts'ebetso ea ho tsepamisa mohopolo ho tlosa litšila tse joalo ka tšepe le titanium le ho ntlafatsa boemo ba concentrate. Thepa ea karohano ea makenete e kenyelletsa moropa oa moqomo oa makenete, karohano ea poleiti ea makenete, selikalikoe se otlolohileng se phahameng sa gradient magnetic separator, joalo-joalo Thepa ea karohano ea makenete le phallo ea ts'ebetso li ikemiselitse ho latela matla a litšila tsa makenete.
Synthetic mullite
Mullite ke thepa ea boleng bo holimo e refractory. Ho na le mekhoa e 'meli ea ho kopanya mullite ho tloha kyenite lisebelisoa tse tala. E 'ngoe ke ho calcine ka ho toba ho theha klinka e bohareng ea aluminium mullite,' me e 'ngoe ke ho eketsa bauxite, alumina le zircon. Majoe, joalo-joalo a calcined ka mocheso o phahameng ho etsa mullite kapa zircon mullite clinker.
