I-Mica ingenye yamaminerali amakhulu akha amadwala, futhi ikristalu inesakhiwo esinezingqimba ngaphakathi, ngakho-ke iveza ikristalu eliyi-hexagonal flake. I-Mica yigama elijwayelekile leqembu lamaminerali e-mica, ikakhulukazi elihlanganisa i-biotite, i-phlogopite, i-muscovite, i-lepidolite, i-sericite, ne-lepidolite.
Izakhiwo Zensimbi Eyigugu kanye Nesakhiwo Sezimbiwa
I-Mica iyiminerali ye-aluminosilicate futhi ihlukaniswe ngamaqembu amathathu amancane: i-muscovite, i-biotite kanye ne-lepidolite. I-Muscovite ihlanganisa i-muscovite kanye ne-sodium mica engavamile; i-biotite ihlanganisa i-phhlogopite, i-biotite, i-manganese biotite; i-lepidolite iyisilinganiso esihle se-mica ehlukahlukene ecebile nge-lithium oxide; i-sericite iyiminerali yobumba enezici ezithile ze-muscovite yemvelo ecolekileyo. Embonini, ikakhulukazi embonini kagesi, i-muscovite kanye ne-phhlogopite zivame ukusetshenziswa. Izingxenye eziyinhloko ze-mica yi-silicon, i-aluminium, i-potassium, i-magnesium, i-lithium, amanzi ekristalu kanye nenani elincane lensimbi, i-manganese, i-titanium, i-chromium, i-sodium, i-calcium, njll. I-Mica inoqhekeko oluphelele futhi ingasuswa. Phakathi kwazo, i-biotite kanye ne-phhlogopite zinezakhiwo ezibuthakathaka ze-magnetic, kanti amanye amashidi e-mica nawo angafakwa ukungcola okufana nensimbi kanye ne-manganese futhi abe nezakhiwo ezithile ze-magnetic ezibuthakathaka. Ubulukhuni be-Mohs bungu-2 ~ 3, ubuningi bungu-2.7 ~ 2.9g/cm3, amaminerali ahlobene avamile yi-pyrite, i-tourmaline, i-beryl, i-feldspar, i-quartz, i-spinel, i-diopside, i-tremolite, njll., phakathi kwawo i-ore yensimbi ephuzi, i-tourmaline, i-spinel, i-diopside, njll. anezakhiwo ezibuthakathaka ze-magnetic.
Izindawo zokusetshenziswa kanye nezinkomba zobuchwepheshe
I-Muscovite inezakhiwo ezinhle zomzimba nezamakhemikhali ezifana namandla aphezulu e-dielectric, ukumelana okuphezulu, ukulahlekelwa okuphansi kwe-dielectric, ukumelana kwe-arc, ukumelana ne-corona, ukuthungwa okuqinile, amandla aphezulu omshini, ukumelana nokushisa okuphezulu, ukumelana ne-asidi ne-alkali, ngakho-ke isetshenziswa kabanzi embonini. Inezindlela eziningi zokusebenzisa; izakhiwo eziyinhloko ze-phlogopite mica ziphansi kancane kune-muscovite mica, kodwa inokumelana nokushisa okuphezulu futhi iyinto enhle yokuvikela ukushisa engashisi; i-fragment mica ibhekisela egameni elijwayelekile le-mica encane ekhishwayo kanye nezinsalela ezikhiqizwa ngokucubungula kanye nokufaka amaphilisi. ; I-Lepidolite, eyaziwa nangokuthi i-phosphomica, iyinto eluhlaza yamaminerali yokukhipha i-lithium, futhi i-sericite isetshenziswa kabanzi enjolobeni, epulasitikini, ensimbini, ezimonyweni, njll.
Ubuchwepheshe Bokucubungula
Ukuzuza kanye nokuhlanzwa
Izindlela zokuhlanza nokuhlanza i-mica ziyahlukahluka kuye ngohlobo lwayo kanye nohlobo lwayo. I-flake mica ngokuvamile isebenzisa ukuhlunga ngesandla, ukuqinisa ukungqubuzana, ukuqinisa ukuma, njll.; i-mica echotshoziwe isebenzisa ukuhlukaniswa komoya kanye nokuntanta, i-biotite kanye ne-phlogopite zingasebenzisa ukuhlukaniswa okunamandla kwamagnetic, i-muscovite, i-lepidolite kanye ne-sericite ziqukethe izakhiwo ezibuthakathaka zamagnetic. Ukungcola kungasuswa futhi ngokuhlukaniswa okunamandla kwamagnetic.
01 Ukukhetha (ukukhomba)
Ebusweni bokumba noma enqwabeni yensimbi emgodini, kukhethwa i-mica ehlukanisiwe ne-monomer, futhi ngokuvamile ifanelekela i-mica enkulu enezinhlayiya.
02 Ukuzuza kokungqubuzana
Ngokuya ngomehluko phakathi kwe-sliding friction coefficient ye-flaky mica crystal kanye ne-rolling friction coefficient ye-round gangue, i-mica crystal kanye ne-gangue ziyahlukaniswa. Enye yemishini esetshenziswayo i-slant plate sorter.
03 Ukuzuza ngesimo
Ngokwezimo ezahlukene zamakristalu e-mica kanye ne-gangue, ikhono lokudlula esikhaleni sesihlungo noma emgodini wesihlungo ngesikhathi sokusihla lihlukile, ukuze i-mica kanye ne-gangue zihlukaniswe.
04 Ukukhetha komoya
Ngemva kokuba isihlabathi kanye nogwadule kuchotshoziwe, i-mica empeleni iba ngesimo sama-flakes, kuyilapho amaminerali e-gangue esesimweni sezinhlayiya ezinkulu. Ngemva kokuhlukaniswa kwamazinga amaningi, kusetshenziswa imishini ekhethekile yokuhlukanisa umoya ngokuya ngomehluko wesivinini sokumiswa ekugelezeni komoya.
05 Ukuntanta
Okwamanje, kunezinqubo ezimbili zokuntanta: enye ukuntanta kwe-mica kanye nabaqoqi be-amine endaweni ene-acidic; enye ukuntanta kanye nabaqoqi be-anionic endaweni ene-alkaline, okudingeka isuswe ushelele ngaphambi kokukhethwa, futhi idinga ukukhethwa izikhathi eziningi.
06 Ukuhlukaniswa kwe-Magnetic
I-Biotite ne-phhlogopite zinezakhiwo ezibuthakathaka ze-magnetic futhi zingakhethwa ngendlela enamandla ye-magnetic; ukungcola kwe-iron oxide kanye ne-iron silicate kuvame ukuhlotshaniswa ne-muscovite, i-sericite kanye ne-lepidolite, okungasuswa futhi ngokuhlukaniswa okunamandla kwe-magnetic. Imishini yokuhlukanisa i-magnetic ihlanganisa ikakhulukazi ama-roller anamandla e-magnetic omile namanzi, ama-separators e-plate magnetic kanye nama-separators e-vertical ring high gradient magnetic.
Susa
Ukuhluba i-mica eluhlaza kube amashidi e-mica anezincazelo ezahlukene kubizwa ngokuthi i-mica peeling. Njengamanje, kunezindlela ezintathu zokuhluba, ezisetshenziswa ngesandla, ezemishini kanye nezomzimba kanye nezamakhemikhali, ezisetshenziselwa ukucubungula njengamashidi amakhulu, amashidi amancane, kanye ne-tube mica.
Ukugaya okuhle nokuhle kakhulu
Kunezinhlobo ezimbili zokukhiqizwa kokugaya okuncane kanye nokugaya okuncane kakhulu kwe-mica, indlela eyomile kanye nendlela emanzi. Ngaphezu kwemishini yokuchoboza nokugaya, indlela eyomile idinga futhi ukuhlonyiswa ngemishini efana nokuhlola kanye nokuhlukaniswa komoya. Ukukhiqizwa okumanzi kusebenzisa imishini ehlukahlukene yokugaya okumanzi, kanti ubuchwepheshe bokugaya okumanzi buyindlela eyinhloko yokuthuthuka ekukhiqizweni kwempuphu ye-mica ecolekile.
Ukuguqulwa kwendawo
Ukuguqulwa kobuso bempuphu ye-mica kungahlukaniswa ngezinqubo ezimbili: ukuguqulwa kobuso bezinto eziphilayo kanye nokuguqulwa kokugqoka kobuso obungaphili. Umkhiqizo we-mica oguquliwe ungathuthukisa amandla okusebenza kwezinto, unciphise izinga lokuncishiswa kokubumba, umphumela omuhle wokubuka obonakalayo futhi uthuthukise inani lokusetshenziswa, njll.
