ʻO nā minelala Kyanite e komo pū ana me ka kyanite, andalusite, a me ka sillimanite. He ʻano like a multiphase nā ʻano ʻekolu, a ʻo ke ʻano kemika ʻo AI2SlO5, nona ka AI2O362.93% a me SiO237.07%. Loaʻa i nā minelala Kyanite ke kūpaʻa kiʻekiʻe, ke kūpaʻa kemika a me ka ikaika mechanical. ʻO lākou nā mea maka o nā mea kūpaʻa kiʻekiʻe a hoʻohana nui ʻia i ka hana ʻana i nā mea kūpaʻa, nā keramika holomua, nā hui alumini-silicon a me nā olonā kūpaʻa.
Nā Waiwai o ka ʻOka a me ke ʻAno o ka Mineral
He pālahalaha kolamu nā kristal Kyanite, uliuli a hina hina paha, vitreous a me ka momi. ʻO ka paʻakikī o ke kuhikuhi hoʻonui kristal like ʻana he 5.5, a ʻo ka paʻakikī o ke kuhikuhi hoʻonui kristal perpendicular he 6.5 a 7, no laila ua kapa ʻia ʻo "ʻelua mau pōhaku paʻakikī", a ʻo ka nui o ka density he 3.56 a 3.68g/cm3. ʻO nā mea nui he kyanite a me kahi liʻiliʻi o ka sillimanite.
He kolamu nā kristal Andalusite, kokoke i ka huinahā ke ʻāpana kea, a hoʻonohonoho ʻia ma ke ʻano kea maʻamau ma ka ʻāpana kea. 3.2g/cm3.
He like me ke kui nā kristal Sillimanite, ʻo ka maʻamau he mau ʻāpana radial a me fibrous, hina-ʻeleʻele a hina-ʻōmaʻomaʻo paha, vitreous, paʻakikī 7, a me ka density 3.23-3.27g/cm3.
Hoʻololi ʻia nā minelala hui Kyanite i loko o ka hui ʻana o ka mullite (ʻike ʻia hoʻi he mullite) a me ka silica (cristobalite) ma hope o ka calcination ma ke ana wela kiʻekiʻe, a hoʻonui ʻia ka nui. ʻO nā minelala pili e pili ana i ka biotite, muscovite, sericite, quartz, graphite, plagioclase, garnet, rutile, pyrite, chlorite a me nā minelala ʻē aʻe.
Nā wahi noi a me nā ʻōkuhi loea
ʻO nā mea refractory nā kahua noi nui o nā minelala kyanite, hiki ke hoʻohana ʻia no ka hana ʻana i nā piliki, hoʻomaikaʻi i ka hana wela kiʻekiʻe o nā huahana refractory, synthesizing mullite i ke kiʻekiʻe wela, a hiki ke hoʻohana ʻia ka kyanite a me ka andalusite crystalline a me ka moakāka e like me nā pōhaku makamae a i ʻole nā hana lima.
Nā hoʻohana nui o nā minelala kyanite:
| Kahua noi | Ka noi nui |
| Kūpaʻa ʻole | Ke hana ʻana i nā piliki refractory, hoʻomaikaʻi i nā piliki pale wela kiʻekiʻe, nā mea refractory i hoʻohālikelike ʻole ʻia |
| Nā keramika | Nā Keramika Kiʻekiʻe, Nā Keramika ʻenehana |
| ʻOihana hao | ʻO ke kola alumini silicon ikaika kiʻekiʻe |
| ʻO ke olonā paʻakikī | ʻO ka uhi kūpaʻa, ka insulator uhi plug spark |
| pōhaku makamae | ʻO ka granularity kristal, ʻālohilohi a moakaka hoʻi e like me ka mea maka no nā pōhaku makamae |
| Lāʻau lapaʻau | Hana ʻana i nā niho kuʻi, ʻākoakoa no nā papa pili iwi haki |
| Kemika | ʻO ka mullite hana wela kiʻekiʻe, mea kūpaʻa waikawa, paipu ana wela kiʻekiʻe |
Ma muli o nā ʻokoʻa hana o nā mea maka mineral like ʻole, nā hoʻohana a me nā pae hana noi, aia nā koi like ʻole no ka maikaʻi o nā hui kyanite.
ʻenehana hana - ka hoʻomaikaʻi ʻana a me ka hoʻomaʻemaʻe ʻana
ʻO ke ʻano hana pono a me ke kaʻina hana ʻenehana o nā minelala kyanite e hilinaʻi nui ʻia i nā ʻano i hoʻopili ʻia o nā minelala, ma ke ʻano he flotation, ka hoʻokaʻawale ʻana o ka umekaumaha a me ka hoʻokaʻawale magnetic, etc.
①Lana
ʻO ka flotation ke ʻano hana nui no ka hoʻomaikaʻi ʻana i nā minelala kyanite, akā ma ke ʻano laulā, pono e hui pū ʻia me nā ʻano hana ʻē aʻe e hoʻokō ai i nā koi o nā ʻōkuhi ʻoihana. Hoʻohana pinepine ʻia ka desliming gravity a i ʻole ka flotation ma hope o ka hoʻokaʻawale magnetic. Hoʻohana nā mea hōʻiliʻili i nā waikawa momona a me ko lākou paʻakai, ka waiwai pH pulp neutral a i ʻole ka waikawa nāwaliwali, ʻo nā mea nui e hoʻohuli ai i ka wili ʻana, nā waiwai haumia, ka hopena desliming, ka ʻōnaehana kemika a me ka waiwai PH pulp.
②Koho hou
No nā minelala kyanite inlaid coarse-grained a me nā minelala kyanite i kāwili ʻia, hoʻohana nui ʻia ke ʻano hoʻokaʻawale umekaumaha, a ʻo nā lako hoʻokaʻawale umekaumaha e komo pū ana me kahi papa lulu, kahi cyclone, kahi medium kaumaha a me kahi chute spiral.
③ʻAno hoʻokaʻawale magnetic
He ʻano hana koʻikoʻi ia i ka hoʻomaikaʻi ʻana i ka kyanite. Hoʻohana nui ʻia ia no ka hoʻomākaukau ʻana i nā mea maka i koho ʻia e hoʻihoʻi a wehe paha i nā huahana magnetic, a i ʻole no nā hana hana hou ʻana i ka concentrate e wehe i nā haumia e like me ka hao a me ka titanium a hoʻomaikaʻi i ka pae concentrate. ʻO nā lako hoʻokaʻawale magnetic e komo pū me ka mea hoʻokaʻawale magnetic drum, ka mea hoʻokaʻawale magnetic plate, ka mea hoʻokaʻawale magnetic gradient kiʻekiʻe apo vertical, a pēlā aku. Hoʻoholo ʻia nā lako hoʻokaʻawale magnetic a me ke kahe o ke kaʻina hana e like me ka ikaika o ka magnetism haumia.
ʻO ka mullite hana
He mea paʻa kiʻekiʻe ka Mullite. ʻElua mau kaʻina hana no ka hana ʻana i ka mullite mai nā mea maka kyanite. ʻO kekahi, ʻo ke calcine pololei ʻana e hana i ka clinker mullite medium-aluminum, a ʻo kekahi, ʻo ka hoʻohui ʻana i ka bauxite, alumina a me ka zircon. Hoʻoheheʻe ʻia nā pōhaku, a pēlā aku i nā mahana kiʻekiʻe e hana i ka mullite a i ʻole ka zircon mullite clinker.
