Mika nimwe mumabuye y'ingenzi akora amabuye y'agaciro, kandi kristu ifite imiterere igororotse imbere, bityo ikerekana kristu ya flake.Mika ni ijambo rusange kumatsinda ya mika yubutare, cyane cyane nka biotite, phlogopite, muscovite, lepidolite, sericite, na lepidolite.
Ibyiza bya Ore nuburyo bwamabuye y'agaciro
Mika ni minerval ya aluminiyose kandi igabanyijemo amatsinda atatu: muscovite, biotite na lepidolite.Muscovite irimo muscovite na mika ya sodium idasanzwe;biotite irimo phlogopite, biotite, biotite ya manganese;lepidolite ni igipimo cyiza cya mika zitandukanye zikungahaye kuri lisiyumu;sericite ni minerval yibumba ifite ibintu bimwe na bimwe biranga muscovite nziza.Mu nganda, cyane cyane mu nganda zamashanyarazi, muscovite na phlogopite bikoreshwa.Ibice byingenzi bigize mika ni silikoni, aluminium, potasiyumu, magnesium, lithium, amazi ya kirisiti hamwe nicyuma gito, manganese, titanium, chromium, sodium, calcium, nibindi. Mika ifite clavage nziza kandi irashobora gukurwaho. Muri bo, biotite na phlogopite bifite imbaraga za rukuruzi, kandi izindi mika zirashobora kandi gushyirwamo umwanda nka fer na manganese kandi bifite imbaraga za rukuruzi.Ubukomezi bwa Mohs ni 2 ~ 3, ubucucike ni 2.7 ~ 2.9g / cm3, amabuye y'agaciro asanzwe ni pyrite, tourmaline, beryl, feldspar, quartz, spinel, diopside, tremolite, nibindi, muribwo ubutare bwumuhondo, tourmaline, spinel, diopside , nibindi bifite intege nke za magnetique.
Ahantu ho gukoreshwa nibipimo bya tekiniki
Muscovite ifite ibintu byiza byumubiri nubumashini nkimbaraga za dielectric, imbaraga nyinshi, gutakaza dielectric nkeya, kurwanya arc, kurwanya corona, imiterere ikomeye, imbaraga za mashini nyinshi, kurwanya ubushyuhe bwinshi, aside na alkali, bityo ikoreshwa cyane mubikorwa.Ifite intera nini yo gukoresha;ibintu nyamukuru bya mika ya phlogopite birarenze gato mika ya muscovite, ariko ifite ubushyuhe bwinshi kandi ni ibikoresho byiza birinda ubushyuhe;mika ibice bivuga ijambo rusange kuri mika nziza yacukuwe hamwe nibisigara byakozwe mugutunganya no kumeza.;Lepidolite, izwi kandi nka fosifike, ni ibikoresho by'amabuye y'agaciro yo gukuramo lithium, kandi serisite ikoreshwa cyane muri reberi, plastiki, metallurgie, kwisiga, n'ibindi.
Ikoranabuhanga
Inyungu no kwezwa
Uburyo bwo kunguka no kweza mika buratandukanye ukurikije imiterere nubwoko.Flake mika muri rusange ikoresha uburyo bwo gutondekanya intoki, kugoboka, kugereranya imiterere, nibindi.;mika yajanjaguwe ifata itandukaniro ryumuyaga no guhindagurika, biotite na phlogopite birashobora gutandukanya imbaraga za magnetique, muscovite, lepidolite na sericite birimo imbaraga za rukuruzi.Imyanda irashobora kandi gukurwaho no gutandukana gukomeye.
01 Gutoranya (kwerekana) guhitamo
Kuruhande rwubucukuzi cyangwa ikirundo cyamabuye kurwobo, mika yatandukanijwe na monomer iratoranijwe, kandi mubisanzwe ikwiranye na mika nini ya flake.
02 Kwunguka
Ukurikije itandukaniro riri hagati ya coefficente yo kunyerera ya kristu ya flake ya mica kristal ya flake na coefficient de coiffe de coiffe ya bande, kristu ya mika na gatsiko biratandukanye.Kimwe mu bikoresho byakoreshejwe ni icyapa kibisi.
03 Inyungu
Ukurikije imiterere itandukanye ya kristu ya mika na gangue, ubushobozi bwo kunyura mu cyuho cya sikeri cyangwa umwobo wa sikeri mugihe cyo kuyungurura biratandukanye, kuburyo mika na gangue bitandukanijwe.
04 Guhitamo umuyaga
Nyuma yo kumenagura umucanga na kaburimbo, mika ahanini iba muburyo bwa flake, mugihe amabuye y'agaciro ya gangue ari mubice binini.Nyuma yo kurwego rwinshi, ibikoresho bidasanzwe bikoreshwa mugutandukanya umuyaga ukurikije itandukaniro ryumuvuduko wo guhagarika mukirere.
05 Flotation
Kugeza ubu, hari inzira ebyiri zo guhinduranya: imwe ni flotation ya mika hamwe na amine ikusanya aside aside;ikindi ni flotation hamwe na anionic yegeranya muburyo bwa alkaline, igomba gukenera mbere yo guhitamo, kandi igomba guhitamo inshuro nyinshi.
06 Gutandukana kwa rukuruzi
Biotite na phlogopite bifite imbaraga za rukuruzi kandi birashobora gutoranywa nuburyo bukomeye bwa magneti;icyuma cya okiside hamwe nicyuma cya silikatike ihujwe na muscovite, sericite na lepidolite, nayo ishobora gukurwaho no gutandukana kwa magneti.Ibikoresho byo gutandukanya magnetiki bikubiyemo cyane cyane ibyuma byuma byumye kandi bitose, ibyuma bya magnetiki bitandukanya hamwe nimpeta ihagaritse ya gradient itandukanya.
Kuramo
Gukuramo mika mbisi mumpapuro za mika zitandukanye zitwa mika gukuramo.Kugeza ubu, hari uburyo butatu bwo gukuramo, aribwo buryo bwintoki, ubukanishi nubumubiri nubumashini, bikoreshwa mugutunganya nk'amabati manini, amabati mato, na mika ya tube.
Gusya neza na ultra-nziza
Hariho ubwoko bubiri bwumusaruro wo gusya neza na ultra-nziza yo gusya mika, uburyo bwumye nuburyo butose.Usibye kumenagura no gusya ibikoresho, uburyo bwumye bugomba no kuba bufite ibikoresho nko kwerekana no gushyira mu kirere.Umusaruro utose ukoresha ibikoresho bitandukanye byo gusya, kandi tekinoroji yo gusya niyo nzira nyamukuru yiterambere mugukora ifu ya mika nziza.
Guhindura isura
Guhindura ubuso bwa poro ya mika birashobora kugabanywamo ibice bibiri: guhindura ubuso kama nubutaka butagaragara.Igicuruzwa cya mika cyahinduwe kirashobora kunoza imbaraga za mashini yibikoresho, kugabanya igipimo cyo kugabanuka, kugabanuka kwiza kwa optique no kunoza agaciro ka progaramu, nibindi.
