Mica yog ib qho ntawm cov pob zeb tseem ceeb uas tsim cov pob zeb, thiab cov siv lead ua muaj cov qauv txheej sab hauv, yog li nws nthuav tawm cov pob zeb hexagonal flake. Mica yog ib lo lus dav dav rau pawg mica ntawm cov minerals, feem ntau suav nrog biotite, phlogopite, muscovite, lepidolite, sericite, thiab lepidolite.
Cov Khoom Siv Ore thiab Cov Qauv Mineral
Mica yog ib hom pob zeb aluminosilicate thiab muab faib ua peb pawg me: muscovite, biotite thiab lepidolite. Muscovite muaj xws li muscovite thiab tsis tshua muaj sodium mica; biotite muaj xws li phlogopite, biotite, manganese biotite; lepidolite yog ib qho nplai me me ntawm ntau yam mica nplua nuj hauv lithium oxide; sericite yog ib hom pob zeb av nplaum uas muaj qee yam ntxwv ntawm cov pob zeb zoo nkauj ntuj. Hauv kev lag luam, tshwj xeeb tshaj yog hauv kev lag luam hluav taws xob, muscovite thiab phlogopite feem ntau siv. Cov khoom tseem ceeb ntawm mica yog silicon, txhuas, potassium, magnesium, lithium, dej siv lead ua thiab me ntsis hlau, manganese, titanium, chromium, sodium, calcium, thiab lwm yam. Mica muaj kev sib cais zoo meej thiab tuaj yeem tev tawm. Ntawm lawv, biotite thiab phlogopite muaj cov khoom sib nqus tsis muaj zog, thiab lwm cov ntawv mica kuj tseem yuav muaj cov khoom tsis huv xws li hlau thiab manganese thiab muaj qee yam khoom sib nqus tsis muaj zog. Mohs hardness yog 2 ~ 3, qhov ceev yog 2.7 ~ 2.9g / cm3, cov zaub mov feem ntau yog pyrite, tourmaline, beryl, feldspar, quartz, spinel, diopside, tremolite, thiab lwm yam, ntawm cov hlau daj ore, tourmaline, spinel, diopside, thiab lwm yam muaj cov khoom sib nqus tsis muaj zog.
Cov cheeb tsam thov thiab cov cim qhia kev txawj
Muscovite muaj cov khoom zoo ntawm lub cev thiab tshuaj xws li lub zog dielectric siab, kev tiv taus siab, kev poob dielectric qis, kev tiv taus arc, kev tiv taus corona, kev ntxhib los mos, lub zog kho tshuab siab, kev tiv taus kub siab, kev tiv taus kua qaub thiab alkali, yog li nws siv dav hauv kev lag luam. Nws muaj ntau yam kev siv; cov khoom tseem ceeb ntawm phlogopite mica qis dua me ntsis rau muscovite mica, tab sis nws muaj kev tiv taus kub siab thiab yog cov khoom siv rwb thaiv tsev zoo; fragment mica txhais tau hais tias lo lus dav dav rau cov mica zoo uas tau khawb thiab cov seem uas tsim los ntawm kev ua thiab kev ua ntsiav tshuaj. ; Lepidolite, tseem hu ua phosphomica, yog cov khoom siv raw rau lithium extraction, thiab sericite siv dav hauv roj hmab, yas, metallurgy, tshuaj pleev ib ce, thiab lwm yam.
Kev Siv Tshuab Ua Haujlwm
Kev pab thiab kev ntxuav
Cov txheej txheem ua kom zoo thiab huv ntawm mica sib txawv raws li nws qhov xwm txheej thiab hom. Flake mica feem ntau siv kev cais tes, kev sib txhuam ua kom zoo, kev ua kom zoo nkauj, thiab lwm yam; crushed mica siv cua sib cais thiab flotation, biotite thiab phlogopite tuaj yeem siv kev sib cais sib nqus muaj zog, muscovite, lepidolite thiab sericite muaj cov khoom sib nqus tsis muaj zog. Cov khoom tsis huv kuj tuaj yeem tshem tawm los ntawm kev sib cais sib nqus muaj zog.
01 Kev xaiv (taw qhia)
Ntawm lub ntsej muag khawb av lossis lub pawg ore ntawm qhov av, cov mica uas tau sib cais los ntawm monomer raug xaiv, thiab nws feem ntau haum rau cov flake mica loj.
02 Kev sib txhuam zoo
Raws li qhov sib txawv ntawm qhov sib txhuam coefficient ntawm cov flaky mica crystal thiab qhov sib txhuam coefficient ntawm cov gangue puag ncig, cov mica crystal thiab cov gangue raug sib cais. Ib qho ntawm cov khoom siv siv yog lub slant plate sorter.
03 Kev ua kom zoo nkauj
Raws li cov duab sib txawv ntawm cov siv lead ua mica thiab gangue, lub peev xwm hla dhau qhov sib txawv ntawm lub sieve lossis lub qhov sieve thaum lub sijhawm sieving yog txawv, yog li ntawd mica thiab gangue raug sib cais.
04 Kev xaiv cua
Tom qab cov xuab zeb thiab cov pob zeb raug tsoo, cov mica yeej yog cov flakes, thaum cov minerals gangue yog cov khoom loj heev. Tom qab ntau theem kev faib tawm, cov khoom siv tshwj xeeb yog siv rau kev sib cais cua raws li qhov sib txawv ntawm qhov ceev ntawm kev ncua hauv cov huab cua.
05 Kev Ua Nkoj
Tam sim no, muaj ob txoj kev flotation: ib qho yog flotation ntawm mica nrog amine collectors hauv ib qho acidic medium; qhov tod yog flotation nrog anionic collectors hauv ib qho alkaline medium, uas yuav tsum tau de-slimed ua ntej xaiv, thiab yuav tsum tau xaiv ntau zaus.
06 Kev sib cais sib nqus
Biotite thiab phlogopite muaj cov khoom sib nqus tsis muaj zog thiab tuaj yeem xaiv los ntawm txoj kev sib nqus muaj zog; cov hlau oxide thiab cov hlau silicate tsis huv feem ntau cuam tshuam nrog muscovite, sericite thiab lepidolite, uas kuj tuaj yeem tshem tawm los ntawm kev sib cais sib nqus muaj zog. Cov khoom siv sib cais sib nqus feem ntau suav nrog cov menyuam sib nqus qhuav thiab ntub, cov phaj sib cais sib nqus thiab cov nplhaib ntsug siab gradient sib nqus separators.
Tshem tawm
Kev tev cov mica nyoos rau hauv cov ntawv mica ntawm ntau yam kev qhia tshwj xeeb hu ua mica peeling. Tam sim no, muaj peb txoj kev tev tawm, uas yog tes, tshuab thiab lub cev thiab tshuaj lom neeg, uas yog siv rau kev ua xws li cov ntawv tuab, cov ntawv nyias, thiab cov raj mica.
Kev sib tsoo zoo thiab ultra-fine
Muaj ob hom kev sib tsoo zoo thiab kev sib tsoo zoo heev ntawm mica, txoj kev qhuav thiab txoj kev ntub. Ntxiv nrog rau cov khoom siv sib tsoo thiab sib tsoo, txoj kev qhuav kuj yuav tsum tau nruab nrog cov khoom siv xws li kev tshuaj ntsuam thiab kev faib tawm huab cua. Kev tsim khoom ntub siv ntau yam khoom siv sib tsoo ntub, thiab cov thev naus laus zis sib tsoo ntub yog qhov tseem ceeb ntawm kev tsim cov hmoov mica zoo.
Kev hloov kho qhov chaw
Kev hloov kho qhov chaw ntawm mica hmoov tuaj yeem muab faib ua ob txoj hauv kev: kev hloov kho qhov chaw organic thiab kev hloov kho qhov chaw inorganic. Cov khoom mica hloov kho tuaj yeem txhim kho lub zog kho tshuab ntawm cov khoom siv, txo qhov molding shrinkage, zoo optical visual effect thiab txhim kho tus nqi thov, thiab lwm yam.
