Amaminerali e-Kyanite afaka i-kyanite, i-andalusite, kanye ne-sillimanite. Lawa amathathu ayizinhlobo ezifanayo nezinezigaba eziningi, kanti ifomula yamakhemikhali yi-AI2SlO5, equkethe i-AI2O362.93% kanye ne-SiO237.07%. Amaminerali e-Kyanite anokumelana okuphezulu, ukuqina kwamakhemikhali kanye namandla omshini. Ayizinto zokusetshenziswa zezinto ezimelana nezinga eliphezulu futhi asetshenziswa kabanzi ekukhiqizweni kwezinto ezimelana ne-iron, izinto zobumba ezithuthukisiwe, ama-aluminium-silicon alloys kanye nemicu emelana ne-iron.
Izakhiwo Zensimbi Eyigugu kanye Nesakhiwo Sezimbiwa
Amakristalu e-Kyanite ayizinsika eziqondile, aluhlaza okwesibhakabhaka noma aluhlaza okwesibhakabhaka-grey, anombala we-vitreous kanye nama-pearly. Ubulukhuni bendlela yokwelulwa kwekristalu ehambisanayo bungu-5.5, kanti ubulukhuni bendlela yokwelulwa kwekristalu eqondile bungu-6.5 kuya ku-7, ngakho-ke kubizwa ngokuthi “amatshe amabili aqinile”, kanti ubuningi bungu-3.56 kuya ku-3.68g/cm3. Izingxenye eziyinhloko yi-kyanite kanye nenani elincane le-sillimanite.
Amakristalu e-Andalusite aqinile, acishe abe yisikwele, futhi ahlelwe ngendlela efanayo yokuwela engxenyeni yokuwela. 3.2g/cm3.
Amakristalu e-Sillimanite afana nenaliti, ngokuvamile ayizinhlayiya ezibanzi nezinemicu, ansundu ngokumpunga noma aluhlaza okotshani, i-vitreous, ubulukhuni obungu-7, kanye nobuningi obungu-3.23-3.27g/cm3.
Amaminerali eqembu le-Kyanite aguqulwa abe yingxube ye-mullite (eyaziwa nangokuthi i-mullite) kanye ne-silica (cristobalite) lapho i-calcination ishisa kakhulu, futhi iyanda ngobuningi. Amaminerali ahlobene afaka phakathi i-biotite, i-muscovite, i-sericite, i-quartz, i-graphite, i-plagioclase, i-garnet, i-rutile, i-pyrite, i-chlorite namanye amaminerali.
Izindawo zokusetshenziswa kanye nezinkomba zobuchwepheshe
Izinto ezivuselelayo ziyizinkambu eziyinhloko zokusetshenziswa kwamaminerali e-kyanite, angasetshenziswa ekwenzeni izitini, ukuthuthukisa ukusebenza kwezinga lokushisa eliphezulu kwemikhiqizo evuselelayo, ukuhlanganisa i-mullite ekushiseni okuphezulu, kanye ne-kyanite ekristalu nebonakalayo kanye ne-andalusite kungasetshenziswa njengamatshe ayigugu noma imisebenzi yezandla.
Ukusetshenziswa okuyinhloko kwamaminerali e-kyanite:
| Inkambu yohlelo lokusebenza | Isicelo esiyinhloko |
| Okungaguquki | Ukwenza izitini ezimelana nokushisa okuphezulu, ukuthuthukisa izitini ezimelana nokushisa okuphezulu, izinto ezingabunjiwe ezimelana nokushisa |
| Izinto zobumba | Izitsha Zobumba Ezithuthukisiwe, Izitsha Zobumba Zobuchwepheshe |
| I-Metallurgy | I-aluminium alloy enamandla aphezulu ye-silicon |
| I-fibre ephikisayo | Ulwelwesi oluyi-refractory, i-spark plug lining insulator |
| itshe eliyigugu | Ubuncane bekristalu, bukhanya futhi busobala njengezinto zokusetshenziswa zamatshe ayigugu |
| Umuthi | Ukwenziwa kwamazinyo okufakelwa, ukuhlanganiswa kwamapuleti okuxhumanisa amathambo aphukile |
| Amakhemikhali | I-mullite yokucubungula izinga lokushisa eliphezulu, izinto ezimelana ne-asidi, ishubhu lokulinganisa izinga lokushisa eliphezulu |
Ngenxa yokwehluka kokusebenza kwezinto zokusetshenziswa zamaminerali ahlukahlukene, ukusetshenziswa kanye namazinga enqubo yokusetshenziswa, kunezidingo ezahlukene zekhwalithi yama-kyanite concentrates.
Ubuchwepheshe bokucubungula - ukuhlomula kanye nokuhlanzwa
Indlela yokuzuza kanye nenqubo yezobuchwepheshe yamaminerali e-kyanite incike kakhulu ezicini ezifakiwe zamaminerali, ngokuvamile ukuntanta, ukuhlukaniswa kwamandla adonsela phansi kanye nokuhlukaniswa kwamagnetic, njll.
①Ukuntanta
I-Flotation iyindlela eyinhloko yokwenza inzuzo yamaminerali e-kyanite, kodwa ngokuvamile idinga ukuhlanganiswa nezinye izindlela ukuze kuhlangatshezwane nezidingo zezinkomba zezimboni. Ukususwa kwamandla adonsela phansi noma ukusatshalaliswa ngemva kokuhlukaniswa kwamagnetic kuvame ukusetshenziswa. Abaqoqi basebenzisa ama-fatty acid kanye nosawoti wawo, inani le-PH le-pulp elingathathi hlangothi noma elibuthakathaka, izici eziyinhloko ezithonyayo ukuqina kokugaya, izakhiwo zokungcola, umphumela we-desliming, uhlelo lwamakhemikhali kanye nenani le-PH le-pulp.
②Khetha kabusha
Kumaminerali e-kyanite ahlanganisiwe ahlanganisiwe asetshenziswa kakhulu, indlela yokuhlukanisa amandla adonsela phansi isetshenziswa kakhulu, futhi imishini yokuhlukanisa amandla adonsela phansi ihlanganisa itafula elinyakazisayo, isivunguvungu, i-medium esindayo kanye ne-spiral chute.
③Indlela yokuhlukanisa ugesi
Kuyindlela ebalulekile ekuzuzeni i-kyanite. Ngokuvamile isetshenziselwa ukulungiselela izinto zokusetshenziswa ezikhethiwe ukuze kutholakale noma kususwe imikhiqizo yamagnetic, noma imisebenzi yokucubungula kabusha i-concentrate ukususa ukungcola okufana ne-iron ne-titanium nokuthuthukisa izinga le-concentrate. Imishini yokuhlukanisa i-magnetic ifaka phakathi i-drum magnetic separator, i-plate magnetic separator, i-vertical ring high gradient magnetic separator, njll. Imishini yokuhlukanisa i-magnetic kanye nokugeleza kwenqubo kunqunywa ngokwamandla e-uncleaning magnetism.
I-mullite yokwenziwa
I-Mullite iyinto esezingeni eliphezulu yokungaguquguquki. Kunezinqubo ezimbili zokuhlanganisa i-mullite ngezinto zokusetshenziswa ze-kyanite. Enye iwukuba i-calcine ngqo ukuze yakhe i-clinker ye-aluminium mullite ephakathi nendawo, kanti enye iwukuba ingeze i-bauxite, i-alumina kanye ne-zircon. Amatshe, njll. afakwa i-calcine emazingeni okushisa aphezulu ukuze akhe i-mullite noma i-zircon mullite clinker.
