Mika nimwe mumabuye y'ingenzi akora amabuye y'agaciro, kandi kristu ifite imiterere igororotse imbere, bityo ikerekana kristu ya flake ya mpandeshatu. Mika ni ijambo rusange kumatsinda ya mika yubutare, cyane cyane harimo biotite, phlogopite, muscovite, lepidolite, sericite, na lepidolite.
Ibyiza bya Ore nuburyo bw'amabuye y'agaciro
Mika ni minerval ya aluminosilike kandi igabanyijemo amatsinda atatu: muscovite, biotite na lepidolite. Muscovite irimo muscovite na micrike ya sodium; biotite irimo phlogopite, biotite, biotite ya manganese; lepidolite ni igipimo cyiza cya mika zitandukanye zikungahaye kuri okiside ya lithium; serisite ni minerval yibumba ifite ibintu bimwe na bimwe biranga muscovite nziza. Mu nganda, cyane cyane mu nganda zamashanyarazi, muscovite na phlogopite bikoreshwa cyane. 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 magneti, kandi andi mashuka ya mika nayo ashobora 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, muri byo harimo ubutare bwumuhondo, tourmaline, spinel, diopside , nibindi bifite imbaraga za magnetique.
Ahantu ho gukoreshwa nibipimo bya tekiniki
Muscovite ifite imiterere myiza yumubiri 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 munganda. Ifite intera nini yo gukoresha; ibintu nyamukuru bya mika ya phlogopite irutwa gato na 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 fatizo byo 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 gutandukanya umuyaga no guhindagurika, biotite na phlogopite birashobora gutandukanya imbaraga za magneti, muscovite, lepidolite na sericite birimo imbaraga za magneti. Umwanda urashobora kandi gukurwaho no gutandukana gukomeye.
01 Gutoranya (kwerekana) guhitamo
Ku isura y'ubucukuzi cyangwa ikirundo cy'amabuye ku mwobo, hatoranijwe mika yatandukanijwe na monomer, kandi muri rusange ikwiranye na mika nini ya flake.
02 Kwunguka
Ukurikije itandukaniro riri hagati ya coeffisente yo kunyerera ya kristu ya mika kristu ya flake na coefficente ya friction yo kuzunguruka ya gangue izengurutse, 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 muburyo buke. Nyuma yo kurwego rwinshi, ibikoresho bidasanzwe bikoreshwa mugutandukanya umuyaga ukurikije itandukaniro ryumuvuduko wo guhagarikwa mukirere.
05 Flotation
Kugeza ubu, hari inzira ebyiri zo guhinduranya: imwe ni flotation ya mika hamwe na koline ya amine muburyo bwa acide; 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 magnetique kandi birashobora gutoranywa nuburyo bukomeye bwa magneti; icyuma cya okiside hamwe nicyuma cya silikatike ikunze guhuzwa na muscovite, sericite na lepidolite, nabyo bishobora kuvanwaho no gutandukana gukomeye kwa magneti. Ibikoresho byo gutandukanya magnetiki bikubiyemo cyane cyane ibyuma byuma byumye kandi bitose, imashini itandukanya isahani hamwe nimpeta ihagaritse impagarike ndende ya magnetiki itandukanya.
Kuramo
Gukuramo mika mbisi mumpapuro za mika ibintu bitandukanye byitwa mika gukuramo. Kugeza ubu, hari uburyo butatu bwo gukuramo, aribwo buryo bwintoki, ubukanishi nubumubiri nubumashini, bikoreshwa mugutunganya nk'impapuro zibyibushye, amabati yoroheje, na mika ya tube.
Gusya neza na ultra-nziza
Hariho ubwoko bubiri bwumusaruro wo gusya neza na ultra-nziza gusya mika, uburyo bwumye nuburyo butose. Usibye kumenagura no gusya ibikoresho, uburyo bwumye bugomba no kuba bufite ibikoresho nko gusuzuma no gushyira ikirere. 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 inzira ebyiri: guhindura ubuso kama nubutaka butagaragara. Igicuruzwa cya mika cyahinduwe kirashobora kunoza imbaraga za mashini yibikoresho, kugabanya igipimo cyo kugabanuka kugabanutse, ingaruka nziza ya optique yo kureba no kuzamura agaciro ka progaramu, nibindi.
