Kyanite minerals muaj xws li kyanite, andalusite, thiab sillimanite. Peb yog homogeneous thiab multiphase variants, thiab cov tshuaj formula yog AI2SlO5, muaj AI2O362.93% thiab SiO237.07%. Kyanite minerals muaj siab refractoriness, tshuaj stability thiab txhua yam muaj zog. Lawv yog cov khoom siv raw ntawm cov khoom zoo refractory thiab yog dav siv nyob rau hauv zus tau tej cov ntaub ntawv refractory, advanced ceramics, aluminium-silicon alloys thiab refractory fibers.
Ore Properties thiab Mineral Structure
Kyanite crystals yog tiaj tus columnar, xiav lossis xiav-grey, vitreous thiab pearly. Lub hardness ntawm parallel siv lead ua extension kev taw qhia yog 5.5, thiab lub hardness ntawm perpendicular siv lead ua extension kev taw qhia yog 6.5 mus rau 7, yog li nws yog hu ua "ob lub pob zeb nyuaj", thiab qhov ceev yog 3.56 mus rau 3.68g / cm3. Cov khoom tseem ceeb yog kyanite thiab ib qho me me ntawm sillimanite.
Andalusite crystals yog columnar, ze li ntawm square nyob rau hauv cross section, thiab teem nyob rau hauv ib tug tsis tu ncua cov duab ntawm tus ntoo khaub lig seem. 3.2g / cm3.
Sillimanite crystals yog koob zoo li, feem ntau radial thiab fibrous aggregates, grey-xim av los yog grey-ntsuab, vitreous, 7 hardness, thiab 3.23-3.27g / cm3 ceev.
Kyanite pab pawg cov zaub mov raug hloov mus rau hauv kev sib xyaw ntawm mullite (tseem hu ua mullite) thiab silica (cristobalite) thaum calcination ntawm qhov kub thiab txias, thiab ua rau lub ntim nthuav dav. Associated minerals muaj xws li biotite, muscovite, sericite, quartz, graphite, plagioclase, garnet, rutile, pyrite, chlorite thiab lwm yam minerals.
Daim ntawv thov thaj chaw thiab cov cim qhia
Cov ntaub ntawv refractory yog cov ntaub ntawv tseem ceeb ntawm kyanite cov zaub mov, uas tuaj yeem siv los ua cov cib, txhim kho qhov kub thiab txias ntawm cov khoom siv refractory, synthesizing mullite ntawm qhov kub thiab txias, thiab crystalline thiab pob tshab kyanite thiab andalusite tuaj yeem siv ua pob zeb lossis khoom siv tes ua.
Kev siv tseem ceeb ntawm kyanite minerals:
| Daim ntawv thov teb | Daim ntawv thov tseem ceeb |
| Refractory | Ua refractory cib, txhim kho qhov kub thiab txias tiv thaiv cib, cov ntaub ntawv tsis zoo li refractory |
| Ceramics | Advanced Ceramics, Technical Ceramics |
| metallurgy | Siab zog silicon aluminium alloy |
| Refractory fiber ntau | Refractory hauv ob sab phlu, spark plug hauv insulator |
| pob zeb diamond | Crystal granularity, ci thiab pob tshab raws li raw khoom rau gemstones |
| Tshuaj kho mob | Kev tsim cov hniav cuav, sib sau ua ke rau cov pob txha sib txuas daim hlau |
| Tshuaj | High kub ua mullite, acid resistant khoom, siab kub ntsuas raj |
Vim qhov kev ua tau zoo sib txawv ntawm ntau yam ntxhia raw cov ntaub ntawv, kev siv thiab kev siv cov txheej txheem, muaj cov kev xav tau sib txawv rau qhov zoo ntawm kyanite concentrates.
Kev siv thev naus laus zis - txiaj ntsig thiab ua kom huv
Txoj kev tau txais txiaj ntsig thiab cov txheej txheem thev naus laus zis ntawm kyanite cov zaub mov feem ntau yog nyob ntawm cov yam ntxwv ntawm cov zaub mov, feem ntau flotation, sib cais lub ntiajteb txawj nqus thiab sib nqus sib nqus, thiab lwm yam.
① Flotation
Flotation yog txoj kev tau txais txiaj ntsig tseem ceeb rau kyanite cov zaub mov, tab sis feem ntau nws yuav tsum tau ua ke nrog lwm txoj hauv kev kom tau raws li qhov yuav tsum tau muaj ntawm cov ntsuas kev lag luam. Lub ntiajteb txawj nqus desliming lossis flotation tom qab sib nqus sib nqus feem ntau siv. Cov neeg siv khoom siv fatty acids thiab lawv cov ntsev, nruab nrab lossis tsis muaj zog acidic pulp PH tus nqi, lub ntsiab tseem ceeb cuam tshuam yog kev sib tsoo fineness, impurity zog, desliming nyhuv, tshuaj system thiab pulp PH nqi.
② Xaiv dua
Rau coarse-grained inlaid thiab mix inlaid kyanite minerals, lub ntiajteb txawj nqus sib cais txoj kev yog feem ntau yog siv, thiab lub ntiajteb txawj nqus sib cais cov khoom muaj xws li ib tug co rooj, ib tug cyclone, ib tug hnyav nruab nrab thiab ib tug kauv chute.
③Magnetic sib cais txoj kev
Nws yog ib txoj hauv kev tseem ceeb hauv kyanite beneficiation. Nws feem ntau yog siv rau kev npaj cov khoom siv raw uas tau xaiv kom rov qab los yog tshem tawm cov khoom sib nqus, lossis rau kev ua haujlwm kom zoo dua qub kom tshem tawm cov impurities xws li hlau thiab titanium thiab txhim kho qib siab. Cov khoom sib nqus sib nqus muaj xws li nruas sib nqus sib nqus, phaj sib nqus sib nqus, lub nplhaib ntsug siab gradient sib nqus sib nqus, thiab lwm yam. Cov khoom sib nqus sib nqus thiab cov txheej txheem ntws tau txiav txim siab raws li lub zog ntawm impurity hlau nplaum.
Synthetic mullite
Mullite yog cov khoom siv zoo refractory. Muaj ob txoj hauv kev rau kev sib txuas mullite los ntawm kyanite raw cov ntaub ntawv. Ib qho yog mus ncaj qha calcine los tsim nruab nrab-aluminium mullite clinker, thiab lwm yam yog ntxiv bauxite, alumina thiab zircon. Pob zeb, thiab lwm yam yog calcined ntawm qhov kub thiab txias los tsim mullite los yog zircon mullite clinker.
