Kyanite minerals inosanganisira kyanite, andalusite, uye sillimanite. Iwo matatu ane homogeneous uye multiphase akasiyana, uye kemikari formula ndeye AI2SlO5, ine AI2O362.93% uye SiO237.07%. Kyanite minerals ane high refractoriness, kugadzikana kwemakemikari uye simba remagetsi. Ndiwo midziyo yemhando yepamusoro-refractory uye inoshandiswa zvakanyanya mukugadzirwa kwezvinhu zvinoramba, maceramics epamusoro, aluminium-silicon alloys uye refractory fibers.
Ore Properties uye Mineral Structure
Kyanite makristasi ari flat columnar, bhuruu kana bhuruu-grey, vitreous uye pearly. Kuomarara kweiyo parallel crystal extension direction ndeye 5.5, uye kuoma kweperpendicular crystal extension direction ndeye 6.5 kusvika ku7, saka inonzi "matombo maviri akaoma", uye density ndeye 3.56 kusvika 3.68g / cm3. Izvo zvikamu zvikuru ndeye kyanite uye shoma shoma ye sillimanite.
Andalusite makristasi ari columnar, angangoita mativi muchinjiko chikamu, uye akarongedzerwa mune yakajairwa muchinjikwa chimiro pamuchinjikwa. 3.2g/cm3.
Sillimanite makristasi akafanana netsono, kazhinji radial uye fibrous aggregates, grey-brown kana grey-girini, vitreous, 7 kuomarara, uye 3.23-3.27g/cm3 density.
Zvicherwa zveboka reKyanite zvinoshandurwa kuita musanganiswa wemullite (inozivikanwawo semullite) uye silica (cristobalite) pacalcination pakupisa kwepamusoro, uye kuwedzera vhoriyamu. Zvicherwa zvakabatana zvinosanganisira biotite, muscovite, sericite, quartz, graphite, plagioclase, garnet, rutile, pyrite, chlorite uye mamwe maminerari.
Nzvimbo dzekushandisa uye zviratidzo zvehunyanzvi
Refractory zvinhu ndiyo mikuru yekushandisa minda yekyanite zvicherwa, izvo zvinogona kushandiswa kugadzira zvidhinha, kuvandudza tembiricha yakakwira yezvigadzirwa zvinoramba, kugadzira mullite pakupisa kwakanyanya, uye crystalline uye yakajeka kyanite uye andalusite inogona kushandiswa sematombo anokosha kana mabasa emaoko.
Kushandiswa kukuru kwekyanite minerals:
| Nzvimbo yekushandisa | Main application |
| Refractory | Kugadzira zvidhinha zvinoramba, kuvandudza tembiricha inodzivirira zvidhinha, isina kuumbwa refractory zvinhu |
| Ceramics | Yepamberi Ceramics, Technical Ceramics |
| Metallurgy | Yakakwirira simba silicon aluminium alloy |
| Refractory fiber | Refractory lining, spark plug lining insulator |
| dombo rinokosha | Crystal granularity, inopenya uye yakajeka seyakagadzirwa zvinhu zvematombo anokosha |
| Mushonga | Kugadzirwa kwemazino emazino, aggregate kune akatyoka bhonzo rekubatanidza ndiro |
| Chemical | Yakakwira tembiricha yekugadzirisa mullite, acid inodzivirira zvinhu, yakanyanya tembiricha yekuyera chubhu |
Nekuda kwekusiyana kwekuita kweakasiyana mamineral raw materials, mashandisiro uye mazinga ekuita kwekushandisa, pane zvakasiyana zvinodiwa zvemhando yekyanite inotarisa.
Processing tekinoroji - kubatsira uye kucheneswa
Nzira yekubatsira uye tekinoroji maitiro emaminerari ekyanite anonyanya kuenderana neakamisikidzwa maitiro emaminerari, kazhinji kutenderera, kupatsanurwa kwegiravhiti uye kupatsanurwa kwemagineti, nezvimwe.
① Flotation
Flotation ndiyo nzira huru yekubatsira yekyanite minerals, asi inowanzoda kusanganiswa nedzimwe nzira kuti isangane nezvinodiwa zvemaindasitiri zviratidzo. Gravity desliming kana flotation mushure mekuparadzaniswa kwemagineti inowanzoshandiswa. Vaunganidzi vanoshandisa mafuta acids uye munyu wavo, kusarerekera kana kusasimba acidic pulp PH kukosha, iyo huru inofurira zvinhu kukuya fineness, kusachena zvimiro, desliming athari, makemikari system uye pulp PH kukosha.
②Sarudza zvakare
Kune yakaomeswa-grained inlaid uye yakasanganiswa inlaid kyanite zvicherwa, iyo nzira yekuparadzanisa giravhiti inonyanya kushandiswa, uye giravhiti yekuparadzanisa midziyo inosanganisira tafura inodedera, dutu, svikiro rinorema uye spiral chute.
③Magineti yekuparadzanisa nzira
Iyo inzira yakakosha mukyanite beneficiation. Inowanzo shandiswa kugadzirira kugadzirwa kwezvinhu zvakasarudzwa kuti zvidzore kana kubvisa zvigadzirwa zvemagineti, kana kutarisisa kudzokorora mashandiro ekubvisa tsvina yakaita sesimbi uye titanium uye kugadzirisa giredhi rekutarisa. Magnetic separation midziyo inosanganisira dhiramu remagineti separator, ndiro yemagineti separator, vertical ring high gradient magineti separator, etc. Iyo magineti yekuparadzanisa midziyo uye kuyerera kwemaitiro zvinotemerwa zvinoenderana nesimba rekusachena magineti.
Synthetic mullite
Mullite ndeyemhando yepamusoro refractory zvinhu. Pane maitiro maviri ekugadzira mullite kubva kukyanite raw materials. Imwe ndeyekunanga calcine kuumba medium-aluminium mullite clinker, uye imwe ndeyekuwedzera bauxite, alumina uye zircon. Matombo, nezvimwewo anoverengerwa pakupisa kwakanyanya kuita mullite kana zircon mullite clinker.
