Mica ndeimwe yemaminerari makuru anoumba matombo, uye kristaro ine chimiro chakaiswa mukati, saka ine kristaro ine hexagonal flake. Mica izwi rekuti mica iboka remaminerari, rinosanganisira biotite, phlogopite, muscovite, lepidolite, sericite, uye lepidolite.
Zvivakwa zveMatombo neMaumbirwo eMineral
Mica iminerali yealuminosilicate uye yakakamurwa kuita mapoka matatu: muscovite, biotite nelepidolite. Muscovite inosanganisira muscovite uye isinganyanyi kunzi sodium mica; biotite inosanganisira phlogopite, biotite, manganese biotite; lepidolite chikero chakanaka chemhando dzakasiyana dzemica dzakapfuma mu lithium oxide; sericite iminerali yevhu ine hunhu hwakasiyana hwemuscovite yakasikwa. Muindasitiri, kunyanya muindasitiri yemagetsi, muscovite nephlogopite zvinowanzoshandiswa. Zvikamu zvikuru zvemica isilicon, aruminiyamu, potassium, magnesium, lithium, crystal water uye simbi shoma, manganese, titanium, chromium, sodium, calcium, nezvimwewo. Mica ine cleavage yakakwana uye inogona kubviswa. Pakati payo, biotite nephlogopite zvine hunhu husina simba hwemagnetic, uye mamwe ma mica sheets anogonawo kuiswa mutsvina yakaita sesimbi ne manganese uye ane hunhu husina simba hwemagnetic. Kuomarara kweMohs kuri 2~3, huwandu hwevanhu huri 2.7~2.9g/cm3, zvicherwa zvakajairika zvinosanganisirwa nechinhu ichi ndeizvi: pyrite, tourmaline, beryl, feldspar, quartz, spinel, diopside, tremolite, nezvimwewo, pakati pazvo pane yellow Iron ore, tourmaline, spinel, diopside, nezvimwewo zvine simba remagineti.
Nzvimbo dzekushandisa uye zviratidzo zvehunyanzvi
Muscovite ine hunhu hwakanaka hwemuviri nemakemikari hwakadai sesimba guru re dielectric, resistance yakakura, dielectric loss shoma, arc resistance, corona resistance, hard texture, high mechanical strength, high tembiricha resistance, acid uye alkali resistance, saka inoshandiswa zvakanyanya mumaindasitiri. Ine mashandisirwo akasiyana-siyana; hunhu hukuru hwe phlogopite mica hwakaderera zvishoma pane muscovite mica, asi ine resistance yakanyanya kupisa uye chinhu chakanaka chinodzivirira kupisa; fragment mica inoreva izwi rekuti fine mica inocherwa uye zvasara zvinogadzirwa nekugadzirisa uye tableting. ; Lepidolite, inozivikanwawo se phosphomica, chinhu chinoshandiswa mukubvisa lithium, uye sericite inoshandiswa zvakanyanya murabha, mapurasitiki, simbi, zvizoro, nezvimwewo.
Tekinoroji Yekugadzirisa
Kubatsirwa uye kucheneswa
Nzira dzekuchenesa nekuchenesa mica dzinosiyana zvichienderana nehunhu hwayo nerudzi rwayo. Mica yeFlake inowanzo sarudza nemaoko, friction beneficiation, shape beneficiation, nezvimwewo; mica yakapwanywa inoshandisa mhepo yekuparadzanisa nekudzika, biotite nephlogopite zvinogona kushandisa simba remagineti rekuparadzanisa, muscovite, lepidolite nesericite zvine simba remagineti. Kusachena kunogonawo kubviswa nekupatsanurwa kwakasimba kwemagineti.
01 Kusarudza (kunongedza)
Pachiso chekuchera kana murwi wematombo ari mugomba, mica yakaparadzaniswa nemonomer inosarudzwa, uye inowanzo kukodzera mica yakakura ine flake.
02 Kubatsira kwekukakavadzana
Zvichienderana nemusiyano uripo pakati pe sliding friction coefficient ye flaky mica crystal ne rolling friction coefficient ye round gangue, mica crystal ne gangue zvakaparadzaniswa. Chimwe chezvishandiso zvinoshandiswa i slant plate sorter.
03 Kubatsira chimiro
Zvichienderana nemaumbirwo akasiyana emakristaro e mica ne gangue, kugona kupfuura nemuburi re sieve kana buri re sieve panguva yekusefa kwakasiyana, zvekuti mica ne gangue zvinoparadzaniswa.
04 Sarudzo yemhepo
Kana jecha nejecha zvapwanywa, mica inenge iri muchimiro chezvimedu, nepo zvicherwa zvegangue zviri muchimiro chezvidimbu zvikuru. Mushure mekupatsanurwa kwezvikamu zvakawanda, michina yakakosha inoshandiswa kupatsanura mhepo zvichienderana nemusiyano wekumhanya kwekumira kwemhepo.
05 Kuyangarara
Parizvino, kune maitiro maviri ekuyangarara: imwe ndeyekuyangarara kwe mica neamine collectors mu acidic medium; imwe ndeyekuyangarara neanionic collectors mu alkaline medium, iyo inoda kubviswa slime isati yasarudzwa, uye inoda kusarudzwa kakawanda.
06 Kupatsanurwa kwemagineti
Biotite nephlogopite dzine hunhu husina simba hwemagineti uye dzinogona kusarudzwa nenzira yakasimba yemagineti; tsvina yesimbi oxide nesimbi silicate inowanzobatanidzwa ne muscovite, sericite ne lepidolite, iyo inogonawo kubviswa nekupatsanurwa kwakasimba kwemagineti. Midziyo yekuparadzanisa magnetic inonyanya kusanganisira maroller emagnetic akasimba akaoma uye akanyorova, ma plate magnetic separator uye ma vertical ring high gradient magnetic separator.
Bvisa
Kubvisa mica mbishi mumapepa e mica ane maitiro akasiyana-siyana kunonzi mica peeling. Parizvino, kune nzira nhatu dzekubvisa mica mbishi, dzinoti nemaoko, dzemuchina uye dzemuviri uye dzemakemikari, dzinoshandiswa pakugadzirisa dzakadai semapepa akakora, machira matete, uye chubhu ye mica.
Kukuya kwakanaka uye kwakanyanya kunaka
Kune mhando mbiri dzekugadzira mica yekukuya zvakanaka uye mica yekukuya zvakanaka, nzira yakaoma uye nzira yakanyorova. Pamusoro pemidziyo yekupwanya nekukuya, nzira yakaoma inofanirawo kuve nemidziyo yakaita sekuongorora nekupatsanura mhepo. Kugadzira mica kunoshandisa michina yakasiyana-siyana yekukuya yakanyorova, uye tekinoroji yekukuya yakanyorova ndiyo nzira huru yekuvandudza kugadzirwa kweupfu hwemica hwakatsetseka.
Kugadziriswa kwepamusoro
Kugadziriswa kweupfu hwemica pamusoro kunogona kukamurwa kuita maitiro maviri: kugadziriswa kweupfu hweorganic uye kugadziriswa kweinorganic surface coating. Chigadzirwa chemica chakagadziriswa chinogona kuvandudza simba remuchina wechinhu chacho, kuderedza mwero wekuumbwa, mhedzisiro yakanaka yekuona uye kuvandudza kukosha kwekushandisa, nezvimwewo.
