ʻO Mica kekahi o nā minelala nui e hana ana i nā pōhaku, a he ʻano papa ko ke kristal i loko, no laila ke hōʻike nei ia i kahi kristal ʻāpana hexagonal. ʻO Mica kahi huaʻōlelo maʻamau no ka hui mica o nā minelala, ʻo ia hoʻi ka biotite, phlogopite, muscovite, lepidolite, sericite, a me ka lepidolite.
Nā Waiwai o ka ʻOka a me ke ʻAno o ka Mineral
He mineral aluminosilicate ʻo Mica a ua māhele ʻia i ʻekolu mau hui liʻiliʻi: muscovite, biotite a me lepidolite. Loaʻa iā Muscovite ka muscovite a ʻoi aku ka liʻiliʻi o ka sodium mica; loaʻa iā biotite ka phlogopite, biotite, manganese biotite; he unahi maikaʻi ka lepidolite o nā ʻano mica like ʻole i waiwai i ka lithium oxide; he mineral lepo ka sericite me kekahi mau ʻano o ka muscovite maikaʻi maoli. I ka ʻoihana, ʻoi aku hoʻi i ka ʻoihana uila, hoʻohana pinepine ʻia ka muscovite a me ka phlogopite. ʻO nā mea nui o ka mica he silicon, alumini, potassium, magnesium, lithium, wai kristal a me kahi liʻiliʻi o ka hao, manganese, titanium, chromium, sodium, calcium, etc. Loaʻa iā Mica ka ʻoki kūpono a hiki ke ʻili ʻia. I waena o lākou, he mau waiwai magnetic nāwaliwali ko biotite a me phlogopite, a hiki ke hoʻokomo ʻia nā pepa mica ʻē aʻe me nā haumia e like me ka hao a me ka manganese a loaʻa iā lākou kekahi mau waiwai magnetic nāwaliwali. ʻO ka paʻakikī o Mohs he 2 ~ 3, ʻo ka density he 2.7 ~ 2.9g / cm3, ʻo nā minelala pili maʻamau he pyrite, tourmaline, beryl, feldspar, quartz, spinel, diopside, tremolite, a pēlā aku, i waena o ia mau mea he mau waiwai magnetic nāwaliwali ka hao melemele, tourmaline, spinel, diopside, a pēlā aku.
Nā wahi noi a me nā ʻōkuhi loea
Loaʻa iā Muscovite nā waiwai kino a me nā kemika maikaʻi e like me ka ikaika dielectric kiʻekiʻe, ke kū'ē kiʻekiʻe, ka pohō dielectric haʻahaʻa, ke kū'ē arc, ke kū'ē corona, ke ʻano paʻakikī, ka ikaika mechanical kiʻekiʻe, ke kū'ē wela kiʻekiʻe, ke kū'ē waikawa a me ka alkali, no laila ua hoʻohana nui ʻia i ka ʻoihana. Loaʻa iā ia kahi ākea o nā hoʻohana; ʻo nā waiwai nui o ka phlogopite mica he haʻahaʻa iki ia ma mua o ka muscovite mica, akā he kiʻekiʻe kona kū'ē wela a he mea hoʻokaʻawale maikaʻi ia e kū'ē i ka wela; ʻo ka fragment mica e pili ana i ka huaʻōlelo maʻamau no ka mica maikaʻi i eli ʻia a me nā koena i hana ʻia e ka hana ʻana a me ka papa ʻana. ; ʻO Lepidolite, i ʻike ʻia hoʻi ʻo phosphomica, he mea maka mineral no ka unuhi lithium, a ua hoʻohana nui ʻia ka sericite i ka rubber, plastics, metallurgy, cosmetics, etc.
ʻenehana hana
Ka hoʻomaikaʻi ʻana a me ka hoʻomaʻemaʻe ʻana
ʻOkoʻa nā ʻano hana hoʻomaikaʻi a me ka hoʻomaʻemaʻe ʻana o ka mika e like me kona ʻano a me kona ʻano. Hoʻohana ka mica flake i ka hoʻokaʻawale lima, ka hoʻomaikaʻi friction, ka hoʻomaikaʻi ʻana i ke ʻano, a pēlā aku; hoʻohana ka mica i kuʻi ʻia i ka hoʻokaʻawale makani a me ka flotation, hiki i ka biotite a me ka phlogopite ke hoʻokaʻawale magnetic ikaika, aia nā waiwai magnetic nāwaliwali o ka muscovite, lepidolite a me ka sericite. Hiki ke wehe ʻia nā haumia e ka hoʻokaʻawale magnetic ikaika.
01 Ke koho ʻana (kuhi ʻana) i ke koho ʻana
Ma ka ʻaoʻao o ke eli ʻana a i ʻole ka puʻu o ka ʻai ma ka lua, ua koho ʻia ka mika i hoʻokaʻawale ʻia mai ka monomer, a he kūpono ia no nā mika ʻōpala nui.
02 Hoʻomaikaʻi ʻana i ka friction
Wahi a ka ʻokoʻa ma waena o ke koina friction paheʻe o ke kristal mica flaky a me ke koina friction ʻōwili o ka gangue poepoe, ua hoʻokaʻawale ʻia ke kristal mica a me ka gangue. ʻO kekahi o nā lako i hoʻohana ʻia he mea hoʻokaʻawale papa slant.
03 Hoʻomaikaʻi ʻana i ke ʻano
Wahi a nā ʻano like ʻole o nā kristal mica a me ke gangue, ʻokoʻa ka hiki ke hele ma waena o ka hakahaka sieve a i ʻole ka lua sieve i ka wā sieving, no laila ua hoʻokaʻawale ʻia ka mica a me ke gangue.
04 Koho makani
Ma hope o ka wāwahi ʻia ʻana o ke one a me ka ʻiliʻili, ʻo ke ʻano o ka mika he mau ʻāpana liʻiliʻi, ʻoiai ʻo nā minelala gangue he mau ʻāpana nui. Ma hope o ka hoʻokaʻawale ʻana i nā pae he nui, hoʻohana ʻia nā lako kūikawā no ka hoʻokaʻawale ʻana i ka makani e like me ka ʻokoʻa o ka wikiwiki o ke kahe ʻana o ka ea.
05 Lana
I kēia manawa, aia ʻelua mau kaʻina hana lana: ʻo kekahi ka lana ʻana o ka mica me nā mea hōʻiliʻili amine i loko o kahi medium acidic; ʻo kekahi ka lana ʻana me nā mea hōʻiliʻili anionic i loko o kahi medium alkaline, pono e hoʻokaʻawale ʻia ma mua o ke koho ʻana, a pono e koho ʻia i nā manawa he nui.
06 Hoʻokaʻawale Magnetic
He nāwaliwali nā waiwai magnetic o Biotite a me phlogopite a hiki ke koho ʻia e ke ʻano magnetic ikaika; pili pinepine ʻia ka hao oxide a me nā haumia silicate hao me muscovite, sericite a me lepidolite, hiki ke wehe ʻia e ka hoʻokaʻawale magnetic ikaika. ʻO nā lako hoʻokaʻawale magnetic e pili ana i nā wili magnetic ikaika maloʻo a pulu, nā mea hoʻokaʻawale magnetic papa a me nā mea hoʻokaʻawale magnetic gradient kiʻekiʻe apo kū pololei.
E ʻili i waho
ʻO ka ʻili ʻana i ka mika maka i loko o nā pepa mika o nā ʻano kikoʻī like ʻole ua kapa ʻia ʻo ka ʻili ʻana o ka mika. I kēia manawa, aia ʻekolu mau ʻano o ka ʻili ʻana, ʻo ia hoʻi ka lima, ka mīkini a me ke kino a me ke kemika, i hoʻohana ʻia no ka hana ʻana e like me nā pepa mānoanoa, nā pepa lahilahi, a me ka mika paipu.
ʻO ka wili maikaʻi a me ka maikaʻi loa
ʻElua ʻano hana o ka wili maikaʻi a me ka wili maikaʻi loa o ka mika, ʻo ke ʻano maloʻo a me ke ʻano pulu. Ma waho aʻe o nā lako hana kuʻi a me ka wili ʻana, pono e hoʻolako ʻia ke ʻano maloʻo me nā lako e like me ka kānana a me ka hoʻokaʻawale ʻana i ka ea. Hoʻohana ka hana pulu i nā lako wili pulu like ʻole, a ʻo ka ʻenehana wili pulu ke ʻano nui o ka hoʻomohala ʻana i ka hana ʻana o ka pauka mika maikaʻi.
Hoʻololi ʻili
Hiki ke hoʻokaʻawale ʻia ka hoʻololi ʻana o ka ʻili o ka pauka mica i ʻelua mau kaʻina hana: ka hoʻololi ʻana o ka ʻili organik a me ka hoʻololi ʻana o ka uhi ʻili inorganic. Hiki i ka huahana mica i hoʻololi ʻia ke hoʻomaikaʻi i ka ikaika mechanical o ka mea, e hōʻemi i ka wikiwiki o ka hoʻohaʻahaʻa ʻana i ka hoʻoheheʻe ʻana, ka hopena ʻike maka maikaʻi a hoʻomaikaʻi i ka waiwai noi, a pēlā aku.
