Impuphu ye-Mica, into esetshenziswa kakhulu ezimbonini, itholakala kumaminerali emvelo e-mica njenge-muscovite, eyaziwa ngemibala yayo engenambala kuya kokukhanyayo, kanye ne-biotite, evame ukubonisa imibala ensundu emnyama kuya kokumnyama. Inqubo yokukhiqiza ihilela ukulandelana okucophelelayo kokuchoboza i-ore eluhlaza bese uyigaya ibe yizinhlayiya ezincane, ukukhipha ngempumelelo isakhiwo se-mica esinezingqimba ezihlukile. Lokhu kuguqulwa kuveza izinhlayiya ezihluka ngobukhulu nesimo, ezilungiselelwe izidingo ezithile zezimboni ezahlukene.​

I-Mica imbiwa emhlabeni wonke, inezindawo ezinkulu zokukhiqiza eNdiya, ezidume nge-muscovite yayo esezingeni eliphezulu; iShayina, umthengisi ohamba phambili onemithombo eminingi yokugcina; kanye ne-United States, ikakhulukazi ezindaweni ezifana neNorth Carolina. Lezi zinsiza zomhlaba wonke ziqinisekisa ukutholakala okuqhubekayo ukuze kuhlangatshezwane nezidingo ezahlukahlukene zezimboni emhlabeni jikelele.

Enye yezimpawu eziphawuleka kakhulu zempuphu ye-mica amandla ayo aphezulu e-dielectric, okwenza kube ukukhetha okuhle kokusetshenziswa kuma-capacitor kanye nokufakwa kwe-elekthronikhi. Lesi sici sivumela i-mica ukuthi imelane nezinkundla zikagesi eziphezulu ngaphandle kokuphuka, sivikele izingxenye zikagesi ezizwelayo ekulimaleni. Ngaphezu kwalokho, i-mica ibonisa ukuzinza kokushisa okumangalisayo, ekwazi ukumelana namazinga okushisa angaphezu kuka-600°C. Lokhu kuqina ekushiseni kuyenza ibe usizo kakhulu ekusetshenzisweni kwezinga lokushisa eliphezulu, njengokukhiqiza izitofu zezimboni kanye nemishini engashisi.​

Izakhiwo ezikhanyayo ze-mica powder nazo zinegalelo ezinhlobonhlobo zokusetshenziswa kwayo. Embonini yezimonyo, amazinga amahle kakhulu e-mica asetshenziselwa ukudala ukukhanya okuncane emikhiqizweni yezimonyo, kusukela kuma-eyeshadow kuya kuma-highlighter. Lo mphumela okhanyayo awugcini nje ngokuthuthukisa ukubukeka kobuhle kodwa futhi unikeza ukuthungwa okubushelelezi nokulinganayo. Kumapende namapulasitiki, i-mica powder isebenza njengesigcwalisi esiqinisayo, ithuthukisa kakhulu ukumelana nesimo sezulu kanye namandla omshini. Ngokuhlakazeka ngokulinganayo ngaphakathi kwe-matrix, izinhlayiya ze-mica zisebenza njengesivikelo emisebeni ye-UV, umswakama, nezinye izici zemvelo, zandisa isikhathi sokuphila somkhiqizo oqediwe.​

Ukusetshenziswa kwempuphu ye-mica ezimbonini kuhlukahlukene ngokulinganayo. Embonini yemishini, isetshenziselwa ukuvikela ukushisa, okusiza ukugcina amazinga okushisa afanele okusebenza ngenkathi kunciphisa ukusetshenziswa kwamandla. Izembozo ezingashisi eziqukethe i-mica powder zinikeza ungqimba olwengeziwe lokuvikela, zinciphisa ukusabalala kwamalangabi futhi zithuthukise ukuphepha komlilo. Ekukhiqizeni irabha, i-mica isebenza njenge-ejenti yokukhulula, ivimbela irabha ukuthi inamathele ezikhumbeni ngesikhathi senqubo yokukhiqiza, ngaleyo ndlela ithuthukise ukusebenza kahle futhi inciphise imfucuza.
