Zvicherwa zveKyanite zvinosanganisira kyanite, andalusite, uye sillimanite. Zvitatu izvi zvakafanana uye zvine mapoinzi akawanda, uye fomura yemakemikari ndeyeAI2SlO5, ine AI2O362.93% uye SiO237.07%. Zvicherwa zveKyanite zvine refractoriness yakakura, kugadzikana kwemakemikari uye simba remakanika. Ndiwo magasi emhando yepamusoro e refractory uye anoshandiswa zvakanyanya mukugadzira zvinhu zvinoramba, ceramics yepamusoro, alloys dzealuminium-silicon uye fibers dzinoramba.
Zvivakwa zveMatombo neMaumbirwo eMineral
Makristasi eKyanite akatsetseka, ebhuruu kana bhuruu-grey, ane vitreous uye ane pearly. Kuoma kwenzira yekuwedzera kristalo yakafanana i5.5, uye kuoma kwenzira yekuwedzera kristalo yakatarisana i6.5 kusvika 7, saka inonzi "matombo maviri akaoma", uye huwandu hwayo i3.56 kusvika 3.68g/cm3. Zvikamu zvikuru ikyanite uye sillimanite shoma.
Makristasi eAndalusite akaita sekoramu, akaita sikweya muchikamu chakachinjika, uye akarongwa muchimiro chakachinjika chakafanana pachikamu chakachinjika. 3.2g/cm3.
Makristasi eSillimanite akafanana netsono, anowanzova maaggregates eradial uye fibrous, grey-brown kana grey-green, vitreous, 7 hardness, uye 3.23-3.27g/cm3 density.
Zvicherwa zveboka reKyanite zvinoshandurwa kuita musanganiswa wemullite (inozivikanwawo semullite) uye silica (cristobalite) kana calcination yakwira, uye zvinowedzerwa huwandu hwezvinhu. Zvicherwa zvakabatana zvinosanganisira biotite, muscovite, sericite, quartz, graphite, plagioclase, garnet, rutile, pyrite, chlorite nezvimwe zvicherwa.
Nzvimbo dzekushandisa uye zviratidzo zvehunyanzvi
Zvinhu zvinodzivirira ngura ndizvo zvinonyanya kushandiswa mukugadzira matombo eKyanite, ayo anogona kushandiswa kugadzira zvidhinha, kuvandudza mashandiro ekupisa kwakanyanya kwezvinhu zvinodzivirira ngura, kugadzira mullite pakupisa kwakanyanya, uye crystalline uye transparent kyanite uye andalusite zvinogona kushandiswa sematombo anokosha kana mabasa emaoko.
Mashandisirwo makuru emaminerari e kyanite:
| Munda wekushandisa | Chikumbiro chikuru |
| Inopikisa | Kugadzira zvidhinha zvinoramba kusimba, kuvandudza zvidhinha zvinoramba kusimba pakupisa kwakanyanya, zvinhu zvisina kuumbwa zvinoramba kusimba |
| Zviumbwa zvesimbi | Zvesimbi zveMadokero, Zvesimbi zveMadokero eUnyanzvi |
| Simbi | Simba guru resilicon aruminiyamu alloy |
| Faibha inonyungudutsa | Mucheka wepurasitiki unodzima, muchina unodziisa spark plug lining |
| dombo rinokosha | Kupenya uye kujeka kwekristaro, kwakajeka uye kwakajeka sezvinhu zvekugadzira matombo anokosha |
| Mushonga | Kugadzirwa kwemazino ekugadzira, akabatanidzwa ekubatanidza mapfupa akatyoka |
| Kemikari | Mullite inogadziriswa nekupisa kwakanyanya, zvinhu zvinodzivirira acid, chubhu yekuyera kupisa kwakanyanya |
Nekuda kwekusiyana kwekushanda kwezvinhu zvakasiyana-siyana zvemineral, mashandisirwo azvo uye mazinga ekushandiswa, pane zvinodiwa zvakasiyana zvemhando ye kyanite concentrates.
Tekinoroji yekugadzirisa - kunatsiridza uye kuchenesa
Nzira yekubatsira uye maitiro ehunyanzvi hwezvicherwa zve kyanite zvinonyanya kutsamira pahunhu hwakadzika hwezvicherwa, kazhinji kuyerera, kupatsanurwa kwegiravhiti uye kupatsanurwa kwemagineti, nezvimwewo.
①Kuyangarara
Kuyerera kwemvura (flotation) ndiyo nzira huru yekunatsiridza minerals dze kyanite, asi kazhinji inofanirwa kubatanidzwa nedzimwe nzira kuti isangane nezvinodiwa neindasitiri. Kubvisa simba remagetsi kana kuyerera kwemvura mushure mekupatsanurwa kwemagineti kunowanzo shandiswa. Vaunganidzi vanoshandisa mafuta acids nemunyu wavo, pulp PH ine neutral kana weakly acid, zvinhu zvikuru zvinopesvedzera kutsetseka kwemvura, hunhu hwekusvibiswa, desliming effect, chemical system uye pulp PH.
②Sarudzazve
Pamaminerari eKyanite ane giravhiti rakawanda uye akasanganiswa, nzira yekuparadzanisa simba regiravhiti ndiyo inonyanya kushandiswa, uye michina yekuparadzanisa simba regiravhiti inosanganisira tafura inozununguka, dutu, nzvimbo inorema uye spiral chute.
③Nzira yekuparadzanisa magineti
Iyi inzira inokosha mukugadzira kyanite. Inowanzo shandiswa pakugadzira zvinhu zvakasarudzwa kuti zvidzore kana kubvisa zvigadzirwa zvemagineti, kana pakugadzirisazve magineti kubvisa tsvina dzakadai sesimbi netitanium uye kuvandudza giredhi remagineti. Midziyo yekuparadzanisa magineti inosanganisira drum magnetic separator, plate magnetic separator, vertical ring high gradient magnetic separator, nezvimwewo. Midziyo yekuparadzanisa magineti uye process flow zvinosarudzwa zvichienderana nesimba remagineti asina kuchena.
Mullite yakagadzirwa
Mullite chinhu chemhando yepamusoro chinodzivisa kusvibiswa. Kune nzira mbiri dzekugadzira mullite kubva kuzvinhu zvakabikwa zve kyanite. Imwe ndeyekugadzira calcine zvakananga kuti igadzire clinker yepakati pealuminium mullite, uye imwe ndeyekuwedzera bauxite, alumina uye zircon. Matombo, nezvimwewo, anoiswa calcine pakupisa kwakanyanya kuti agadzire mullite kana zircon mullite clinker.
