Mica ndeimwe yemaminerari ekugadzira dombo, uye kristaro ine dhizaini yemukati, saka inopa hexagonal flake crystal.Mica izwi rinowanzoreva boka remica yemaminerari, kunyanya kusanganisira biotite, phlogopite, muscovite, lepidolite, sericite, uye lepidolite.
Ore Properties uye Mineral Structure
Mica ndeye aluminosilicate mineral uye yakakamurwa kuita zvikamu zvitatu: muscovite, biotite uye lepidolite.Muscovite inosanganisira muscovite uye zvishoma zvisingawanzo sodium mica;biotite inosanganisira phlogopite, biotite, manganese biotite;lepidolite chiyero chakanaka chemica yakasiyana-siyana yakapfuma mu lithium oxide;sericite chicherwa chevhu chine humwe hunhu hwemusikirwo wakanaka-grained muscovite.Muindasitiri, kunyanya muindasitiri yemagetsi, muscovite uye phlogopite inowanzoshandiswa.Izvo zvikamu zvikuru zvemica ndeye silicon, aluminium, potassium, magnesium, lithium, crystal mvura uye shoma shoma yesimbi, manganese, titanium, chromium, sodium, calcium, etc. Mica ine cleavage yakakwana uye inogona kubviswa. biotite uye phlogopite zvine simba remagineti zvimiro, uye mamwe mica sheets anogona zvakare kunyudzwa netsvina yakaita sesimbi uye manganese uye ane mamwe asina simba remagineti.Mohs kuomarara ndeye 2 ~ 3, density ndeye 2.7 ~ 2.9g / cm3, akajairika akabatanidzwa maminerari ari pyrite, tourmaline, beryl, feldspar, quartz, spinel, diopside, tremolite, nezvimwewo, pakati peiyo yero Iron ore, tourmaline, spinel, diopside. , nezvimwewo vane simba remagineti risina simba.
Nzvimbo dzekushandisa uye zviratidzo zvehunyanzvi
Muscovite ine yakanaka yemuviri uye kemikari midziyo yakadai seyakakwira dielectric simba, kupikisa kwepamusoro, kuderera kwe dielectric kurasikirwa, arc resistance, corona resistance, hard texture, high mechanical simba, high temperature resistance, acid uye alkali resistance, saka inoshandiswa zvakanyanya mumaindasitiri.Iine huwandu hwakawanda hwekushandisa;iyo mikuru midziyo yephlogopite mica yakaderera zvishoma kune muscovite mica, asi ine yakanyanya kupisa kupisa uye yakanaka inodzivirira kupisa insulating zvinhu;fragment mica inoreva izwi rinowanzoreva mica yakanaka inocherwa uye zvakasara zvinogadzirwa nekugadziriswa uye kunwa mapiritsi.;Lepidolite, inozivikanwawo se phosphomica, ndeye mineral raw material ye lithium extraction, uye sericite inoshandiswa zvakanyanya murabha, mapurasitiki, metallurgy, cosmetics, nezvimwe.
Processing Technology
Beneficiation uye kucheneswa
Kubatsira uye nzira dzekuchenesa dze mica dzinosiyana zvichienderana nechimiro chayo uye mhando.Flake mica inowanzo tora manyorero ekugadzirisa, friction beficiation, shape beneficiation, nezvimwewo;yakapwanyika mica inotora kupatsanurwa kwemhepo uye kuyerera, biotite uye phlogopite inogona kutora yakasimba magineti separation, muscovite, lepidolite uye sericite ine isina simba remagineti.Kusvibiswa kunogonawo kubviswa nekuparadzaniswa kwakasimba kwemagineti.
01 Kunhonga (kunongedza) kusarudzwa
Pachiso chemugodhi kana murwi weore pagomba, iyo mica yakaparadzaniswa kubva kune monomer inosarudzwa, uye inowanzoenderana nehombe flake mica.
02 Friction beficiation
Zvinoenderana nemusiyano uripo pakati peinotsvedza friction coefficient ye flaky mica crystal uye rolling friction coefficient ye round gangue, mica crystal ne gangue zvakapatsanurwa.Imwe yemidziyo inoshandiswa ndeye slant plate sorter.
03 Shape kubatsirwa
Maererano nemhando dzakasiyana-siyana dzemica crystals uye gangue, kukwanisa kudarika nepakati pesefa kana gomba rekusefa panguva yekusefa kwakasiyana, kuitira kuti mica uye gangue zviparadzaniswe.
04 Kusarudzwa kwemhepo
Mushure mekunge jecha nematombo zvapwanywa, mica inenge iri muchimiro chemafuta, nepo maminerari e gangue ari muchimiro chezvimedu zvakakura.Mushure mekugadzika kweakawanda-level, yakakosha michina inoshandiswa pakuparadzanisa mhepo zvinoenderana nemusiyano wekumhanya kwekumisa mumhepo.
05 Flotation
Parizvino, kune maitiro maviri ekuyangarara: imwe ndeyekutenderera kwe mica ine amine vaunganidzi mune ine acidic medium;imwe yacho inoyangarara nevaunganidzi veanionic mune alkaline medium, inoda kuderedzwa isati yasarudzwa, uye inoda kusarudzwa kakawanda.
06 Magnetic kupatsanurwa
Biotite uye phlogopite vane simba remagineti uye rinogona kusarudzwa nenzira yakasimba yemagineti;iron oxide uye iron silicate tsvina inowanzobatanidzwa ne muscovite, sericite uye lepidolite, iyo inogonawo kubviswa nekuparadzaniswa kwakasimba kwemagineti.Magnetic kupatsanura michina inonyanya kusanganisira yakaoma uye yakanyorova yakasimba magineti rollers, ndiro yemagineti separators uye yakatwasuka mhete yakakwira gradient magineti separators.
Peel off
Kusvuura mica mumica mapepa ezvakasiyana zvinodaidzwa kuti mica peeling.Parizvino, kune nzira nhatu dzekusvuura, dzinova dzemanyorero, dzemuchina uye dzemuviri nemakemikari, dzinoshandiswa kugadzira semashizha akakora, mashizha matete, uye chubhu mica.
Yakanaka uye yakanyanya-yakanaka kugaya
Kune marudzi maviri ekugadzirwa kwehunyoro uye ultra-fine kugaya ye mica, yakaoma nzira uye yekunyorova nzira.Pamusoro pekupwanya uye kukuya michina, yakaoma nzira inodawo kuve nemidziyo yakadai seyekuvheneka uye kurongedza mhepo.Kugadzirwa kwemvura kunoshandisa zvakasiyana-siyana zvekuya zviya, uye tekinoroji yekukuya ndiyo nzira huru yekusimudzira mukugadzirwa kwehupfu hwemica.
Kugadziriswa kwepamusoro
Iko kugadziridzwa kwepamusoro kwe mica poda inogona kukamurwa kuita maviri maitiro: organic pamusoro pekugadzirisa uye inorganic surface coating shanduko.Iyo yakagadziridzwa mica chigadzirwa inogona kuvandudza simba remuchina wechinhu, kuderedza kuumbwa kwe shrinkage rate, yakanaka yekuona maitiro uye kugadzirisa kukosha kwekushandisa, nezvimwe.
