Iiminerali zeKyanite ziquka i-kyanite, i-andalusite, kunye ne-sillimanite. Ezi zintathu ziintlobo ezahlukeneyo ze-homogeneous kunye ne-multiphase, kwaye ifomula yekhemikhali yi-AI2SlO5, equlethe i-AI2O362.93% kunye ne-SiO237.07%. Iiminerali zeKyanite zinamandla aphezulu okuchasana, uzinzo lweekhemikhali kunye namandla oomatshini. Zizinto ezisetyenziswa kwizixhobo zokuchasana ezikumgangatho ophezulu kwaye zisetyenziswa kakhulu kwimveliso yezinto zokuchasana, iiseramikhi eziphambili, ii-aluminium-silicon alloys kunye neefayibha zokuchasana.
Iipropati ze-ore kunye nolwakhiwo lwezimbiwa
Iikristale zeKyanite zithe tyaba, ziluhlaza okwesibhakabhaka okanye zingwevu-luhlaza okwesibhakabhaka, zifana ne-vitreous kwaye zifana neperile. Ubunzima becala lolwandiso lwekristale oluhambelanayo yi-5.5, kwaye ubunzima becala lolwandiso lwekristale oluthe nkqo yi-6.5 ukuya kwi-7, ngoko ke ibizwa ngokuba "ngamatye amabini aqinileyo", kwaye ubuninzi buyi-3.56 ukuya kwi-3.68g/cm3. Izinto eziphambili yi-kyanite kunye nenani elincinci le-sillimanite.
Iikristale zeAndalusite zikholamu, ziphantse zibe sikwere kwicala elinqamlezileyo, kwaye zibekwe ngendlela eqhelekileyo kwicala elinqamlezileyo. 3.2g/cm3.
Iikristale zeSillimanite zifana neenaliti, zihlala ziyi-radial kunye ne-fibrous aggregates, zingwevu-mdaka okanye zingwevu-luhlaza, ziyi-vitreous, zilukhuni lwe-7, kwaye zixinene yi-3.23-3.27g/cm3.
Iiminerali zeqela leKyanite ziguqulwa zibe ngumxube we-mullite (ekwaziwa ngokuba yi-mullite) kunye ne-silica (cristobalite) xa i-calcination ikwiqondo lobushushu eliphezulu, kwaye ziyanda ngobuninzi. Iiminerali ezinxulumene nazo ziquka i-biotite, i-muscovite, i-sericite, i-quartz, i-graphite, i-plagioclase, i-garnet, i-rutile, i-pyrite, i-chlorite kunye nezinye iiminerali.
Iindawo zokusetyenziswa kunye nezalathisi zobugcisa
Izinto ezivuselelayo zezona ndawo ziphambili zokusetyenziswa kweeminerali ze-kyanite, ezinokusetyenziselwa ukwenza izitena, ukuphucula ukusebenza kobushushu obuphezulu kweemveliso ezivuselelayo, ukwenziwa kwe-mullite kubushushu obuphezulu, kwaye i-cyanite ekhanyayo kunye ne-andalusite zingasetyenziswa njengezinto zamatye anqabileyo okanye imisebenzi yezandla.
Ukusetyenziswa okuphambili kweeminerali ze-kyanite:
| Intsimi yesicelo | Isicelo esiphambili |
| I-Refractory | Ukwenza izitena ezichasayo, ukuphucula izitena ezichasayo kubushushu obuphezulu, izinto ezichasayo ezingabumbekanga |
| Iiseramikhi | Iiceramics eziPhambili, iiceramics zobugcisa |
| iMetallurgy | I-aluminium alloy enamandla aphezulu ye-silicon |
| Ifayibha erhabaxa | I-lining erhabaxa, i-spark plug lining insulator |
| ilitye elinqabileyo | Ubuncinci bekristale, bukhanya kwaye bubonakala njengezinto eziluhlaza zelitye elinqabileyo |
| Iyeza | Ukwenziwa kwamazinyo okufakelwa, aggregate yeepleyiti zokudibanisa amathambo aphukileyo |
| Ikhemikhali | I-mullite yokucubungula ubushushu obuphezulu, izinto ezimelana ne-asidi, ityhubhu yokulinganisa ubushushu obuphezulu |
Ngenxa yokwahluka kokusebenza kwezinto ezahlukeneyo zeminerali, ukusetyenziswa kunye namanqanaba enkqubo yokusetyenziswa, kukho iimfuno ezahlukeneyo zomgangatho we-kyanite concentrates.
Itekhnoloji yokucubungula - ukuhluza kunye nokucoca
Indlela yokuzuza kunye nenkqubo yetekhnoloji yeeminerali ze-kyanite zixhomekeke kakhulu kwiimpawu ezifakwe ngaphakathi kwezi minerali, ngokubanzi ukutyibilika, ukwahlukana komxhuzulane kunye nokwahlukana kwemagnethi, njl.njl.
①Ukudada
I-Flotation yeyona ndlela iphambili yokwenza i-kyanite minerals ibe mnandi, kodwa ngokubanzi kufuneka idityaniswe nezinye iindlela ukuhlangabezana neemfuno zeempawu zoshishino. Ukususa i-gravity okanye i-flotation emva kokwahlulwa kwemagnethi zihlala zisetyenziswa. Abaqokeleli basebenzisa ii-fatty acids kunye neetyuwa zazo, ixabiso le-PH ye-pulp engathathi hlangothi okanye ebuthathaka, izinto eziphambili ezichaphazelayo kukucola kokugaya, iipropati zokungcola, isiphumo se-desliming, inkqubo yeekhemikhali kunye nexabiso le-PH ye-pulp.
②Khetha kwakhona
Kwiminerali ze-kyanite ezifakwe iingceba ezirhabaxa nezixutyiweyo, indlela yokwahlula amandla omhlaba isetyenziswa kakhulu, kwaye izixhobo zokwahlula amandla omhlaba ziquka itafile yokushukuma, isivunguvungu, i-medium enzima kunye ne-spiral chute.
③Indlela yokwahlulahlula ngemagnethi
Yindlela ebaluleke kakhulu ekuphuculeni i-kyanite. Isetyenziswa ngokubanzi ekulungiseleleni izinto ezikhethiweyo zokubuyisela okanye ukususa iimveliso zemagnethi, okanye kwimisebenzi yokuhlaziya i-concentrate ukususa ukungcola okufana nentsimbi kunye ne-titanium kunye nokuphucula umgangatho we-concentrate. Izixhobo zokwahlula i-magnetic ziquka i-drum magnetic separator, i-plate magnetic separator, i-vertical ring high gradient magnetic separator, njl. Izixhobo zokwahlula i-magnetic kunye nokuhamba kwenkqubo kumiselwa ngokwamandla emagnethi yokungcola.
I-mullite yokwenziwa
I-Mullite yinto ekumgangatho ophezulu enokuchasana ne-refractory. Kukho iinkqubo ezimbini zokwenza i-mullite ngezinto ezikrwada ze-kyanite. Enye kukwenza i-calcine ngqo ukuze yenze i-medium-aluminium mullite clinker, kwaye enye kukongeza i-bauxite, i-alumina kunye ne-zircon. Amatye, njl.njl. afakwa i-calcine kubushushu obuphezulu ukuze yenze i-mullite okanye i-zircon mullite clinker.
