Mica yog ib qho ntawm cov pob zeb tsim cov pob zeb tseem ceeb, thiab cov siv lead ua muaj cov txheej txheem txheej sab hauv, yog li nws nthuav tawm hexagonal flake crystal. Mica yog ib lub ntsiab lus dav dav rau pawg mica ntawm cov zaub mov, feem ntau suav nrog biotite, phlogopite, muscovite, lepidolite, sericite, thiab lepidolite.
Ore Properties thiab Mineral Structure
Mica yog cov ntxhia aluminosilicate thiab muab faib ua peb pawg: muscovite, biotite thiab lepidolite. Muscovite suav nrog muscovite thiab tsawg dua sodium mica; biotite suav nrog phlogopite, biotite, manganese biotite; lepidolite yog cov nplai zoo ntawm ntau yam mica nplua nuj hauv lithium oxide; sericite yog av nplaum ntxhia nrog tej yam ntxwv ntawm ntuj zoo-grained muscovite. Hauv kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev lag luam hluav taws xob, muscovite thiab phlogopite feem ntau siv. Cov khoom tseem ceeb ntawm mica yog silicon, aluminium, potassium, magnesium, lithium, siv lead ua dej thiab ib qho me me ntawm cov hlau, manganese, titanium, chromium, sodium, calcium, thiab lwm yam. biotite thiab phlogopite muaj cov khoom sib nqus tsis muaj zog, thiab lwm cov ntaub ntawv mica kuj tseem tuaj yeem kos nrog impurities xws li hlau thiab manganese thiab muaj qee yam tsis muaj zog hlau nplaum. Mohs hardness yog 2 ~ 3, ceev yog 2.7 ~ 2.9g / cm3, ntau yam minerals muaj xws li pyrite, tourmaline, beryl, feldspar, quartz, spinel, diopside, tremolite, thiab lwm yam, ntawm cov uas daj hlau ore, tourmaline, spinel, diopside , thiab lwm yam muaj zog magnetic zog.
Daim ntawv thov thaj chaw thiab cov cim qhia
Muscovite muaj cov khoom zoo ntawm lub cev thiab tshuaj lom neeg xws li siab dielectric zog, siab tsis kam, tsis tshua muaj dielectric poob, arc tsis kam, corona tsis kam, tawv zoo nkauj, siab mechanical zog, kub tsis kam, acid thiab alkali tsis kam, yog li nws yog dav siv hauv kev lag luam. Nws muaj ntau yam kev siv; Cov khoom tseem ceeb ntawm phlogopite mica yog me ntsis qis dua muscovite mica, tab sis nws muaj cov cua kub tsis kam thiab yog cov khoom siv hluav taws kub-resistant insulating; fragment mica yog hais txog cov lus dav dav rau cov mica zoo uas yog mined thiab cov khoom seem uas tsim los ntawm kev ua thiab cov ntsiav tshuaj. ; Lepidolite, tseem hu ua phosphomica, yog cov khoom siv ntxhia rau lithium extraction, thiab sericite yog siv dav hauv roj hmab, plastics, metallurgy, tshuaj pleev ib ce, thiab lwm yam.
Kev Siv Tshuab
Kev pab thiab purification
Cov txiaj ntsig thiab kev ua kom huv ntawm mica sib txawv raws li nws qhov xwm txheej thiab hom. Flake mica feem ntau lees txais kev txheeb xyuas phau ntawv, kev sib txhuam kom zoo, zoo li qub, thiab lwm yam.; crushed mica txais cua sib cais thiab flotation, biotite thiab phlogopite tuaj yeem txais kev sib nqus sib nqus, muscovite, lepidolite thiab sericite muaj zog sib nqus. Cov impurities tuaj yeem raug tshem tawm los ntawm kev sib nqus sib nqus.
01 Xaiv (taw tes) xaiv
Ntawm lub ntsej muag mining los yog cov ore pawg ntawm lub qhov, cov mica uas tau muab cais los ntawm cov monomer yog xaiv, thiab nws yog feem ntau haum rau loj flake mica.
02 Friction Beneficiation
Raws li qhov sib txawv ntawm zawv zawg kev sib txhuam coefficient ntawm flaky mica siv lead ua thiab dov kev sib txhuam coefficient ntawm puag ncig gangue, cov mica siv lead ua thiab cov gangue sib cais. Ib qho ntawm cov cuab yeej siv yog lub phaj slant sorter.
03 Cov txiaj ntsig zoo
Raws li cov duab sib txawv ntawm mica crystals thiab gangue, muaj peev xwm dhau los ntawm qhov sib txawv ntawm lub sieve los yog lub sieve qhov thaum lub sij hawm sieving txawv, yog li ntawd mica thiab gangue sib cais.
04 Cua xaiv
Tom qab cov xuab zeb thiab gravel raug crushed, lub mica yog ib qho yooj yim nyob rau hauv daim ntawv ntawm flakes, thaum lub gangue minerals nyob rau hauv daim ntawv ntawm loj hais. Tom qab ntau theem kev faib tawm, cov cuab yeej tshwj xeeb yog siv rau kev sib cais cua raws li qhov sib txawv ntawm qhov ncua kev ncua kev ceev hauv airflow.
05 Flotation
Tam sim no, muaj ob txoj kev flotation: ib qho yog flotation ntawm mica nrog amine collectors nyob rau hauv ib tug acidic nruab nrab; lwm qhov yog flotation nrog anionic collectors nyob rau hauv ib tug alkaline nruab nrab, uas yuav tsum tau de-slimed ua ntej xaiv, thiab yuav tsum tau xaiv ntau zaus.
06 Sib nqus sib cais
Biotite thiab phlogopite muaj cov khoom sib nqus tsis muaj zog thiab tuaj yeem xaiv los ntawm txoj kev sib nqus muaj zog; hlau oxide thiab hlau silicate impurities feem ntau txuam nrog muscovite, sericite thiab lepidolite, uas kuj yuav raug tshem tawm los ntawm muaj zog sib nqus sib cais. Cov khoom sib nqus sib nqus feem ntau suav nrog qhuav thiab ntub dej muaj zog sib nqus sib nqus, phaj sib nqus sib nqus thiab ntsug nplhaib siab gradient sib nqus sib nqus.
Tshem tawm
Peeling nyoos mica rau hauv mica nplooj ntawm ntau yam specifications yog hu ua mica peeling. Tam sim no, muaj peb txoj kev ntawm tev, uas yog phau ntawv, txhua yam thiab lub cev thiab tshuaj, uas yog siv rau kev ua xws li cov ntawv tuab, cov ntawv nyias, thiab lub raj mica.
Fine thiab ultra-fine sib tsoo
Muaj ob hom kev sib tsoo zoo thiab kev sib tsoo ultra-nplua ntawm mica, txoj kev qhuav thiab txoj kev ntub dej. Ntxiv nrog rau cov khoom siv crushing thiab sib tsoo, txoj kev qhuav kuj yuav tsum tau nruab nrog cov khoom siv xws li kev tshuaj ntsuam xyuas thiab kev faib huab cua. Kev tsim khoom ntub dej siv ntau yam khoom siv sib tsoo ntub dej, thiab ntub kev sib tsoo tshuab yog qhov kev txhim kho tseem ceeb hauv kev tsim cov hmoov zoo mica hmoov.
Kev hloov kho saum npoo
Kev hloov kho saum npoo ntawm mica hmoov tuaj yeem muab faib ua ob txoj hauv kev: kev hloov pauv ntawm cov organic thiab inorganic deg txheej hloov kho. Cov khoom hloov kho mica tuaj yeem txhim kho lub zog ntawm cov khoom siv, txo cov molding shrinkage tus nqi, zoo kho qhov muag pom kev zoo thiab txhim kho daim ntawv thov nqi, thiab lwm yam.
