【Huate Mineral Processing Encyclopedia】Pepuru kumusoro! Huate Magneto Simba Inosimudzira Yakakwira-Unhu Kukudziridzwa kweFluorite Kuronga Indasitiri Yekugadzira Mutsetse
Fluorite, inozivikanwawo se fluorite, yakapfuma muyttrium inonzi yttrium fluorite. Makristasi acho anowanzo cubic, octahedron, uye shoma rhombic dodecahedron. A common mineral in nature, mamwe ma samples anogona kuburitsa chiedza kana aiswa friction, heat, ultraviolet radiation, etc. Haiwanzo shandiswa segemu nekuda kwebrittleness uye kupfava kwayo. Muindasitiri, fluorite ndiyo sosi huru yekubvisa uye kugadzirira kweakasiyana makomisheni akadai sefluorine uye hydrofluoric acid, uye fluorite zvienzaniso zvine mavara akajeka uye akanakisa mafomu ekristaro anogona kushandiswa kuunganidza, kushongedza uye kuveza art.
Ore Properties uye Mineral Structure
Fluorite inoumbwa neCaF2, ine 48.67% fluorine, 51.33% calcium, uye dzimwe nguva zvisingawanzo zvinhu. Inowanzo symbiotic nequartz, calcite, barite uye simbi sulfide, mune granular kana yakakura aggregates, kazhinji yero uye girini. , yebhuruu, yepepuru, nezvimwewo, isina ruvara, vitreous luster, yakaoma 4, density 3.18g/cm3, inopisa kana fluorescent pasi pe ultraviolet chiedza. Fluorite hainyungudike mumvura, inonyungudika mu sulfuric acid, phosphoric acid uye inopisa hydrochloric acid, boric acid, hypochlorous acid, uye inogona kuita zvishoma nezvigadziko zvakasimba zvakaita se potassium hydroxide uye sodium hydroxide, ine nzvimbo yekunyungudika ye1360 °C.
Nzvimbo dzekushandisa uye zviratidzo zvehunyanzvi
Fluorite ine halogen element fluorine, inova ndiyo huru mbishi yekugadzira fluorine makomisheni, uye inoshandiswa zvakanyanya mukugadzira simbi, isiri-ferrous simbi kunyungudutsa, simende, girazi, ceramics, nezvimwewo nekuda kwekuderera kwayo kunyungudika. Inowanikwa se optical fluorite uye craft fluorite.

Processing Technology
Beneficiation uye Kucheneswa
Minerals symbiotic ine fluorite ndeiyi: quartz, calcite, scheelite, apatite, cassiterite, wolframite, pyrite, sphalerite, lapis lazuli, muscovite, galena, chalcopyrite, rhodochrosite Manganese ore, dolomite, spinel potassium felds, etc. muzvinhu zvemaminerari akabatanidzwa mufluorite, kupatsanurwa uye kucheneswa kunoitwa neflotation, kupatsanurwa kwemagineti, kupatsanurwa kwegiravhiti uye dzimwe nzira dzekubatsira.
① Flotation
Flotation ndiyo inonyanya kukosha nzira ye fluorite beneficiation. Iyo general process ndeyekuunganidza fatty acids mushure mekugaya, uye sarudza inokwanisa fluorite concentrate zvigadzirwa kuburikidza nemaitiro akawanda ekusarudza; nokuda kwezvicherwa zve sulfide, yero Mishonga inosarudzwa, uye iyo yakabatana barite, calcite, muscovite, nezvimwewo inoparadzaniswa neinhibitors.
②Kusarudzazve - kutenderera
Kana iyo ore giredhi yakadzikira kana ine yakawanda miviri yakakasharara yakabatana, iyo yakasanganiswa maitiro ekuparadzaniswa kwegiravhiti uye flotation inowanzo shandiswa.
③ Magnetic kupatsanurwa - flotation
Kana paine magineti iron kana iron okisidhi yakawanda muore, dhiramu remagineti separator rinogona kushandiswa kupatsanura simba remagineti iron kana vertical ring yemagnetic separator kubvisa iyo isina simba remagineti iron oxide uye wobva wapfuura nemunzira yekuyangarara; kana paine mashoma emaminerari esimbi mune yekutanga ore, Nekudaro, kana iyo iron yemukati ye flotation fluorite concentrate inopfuura mwero, vertical mhete kana electromagnetic slurry yakakwirira gradient magineti separator inogona kushandiswa kubvisa iron oxide zvicherwa mune fluorite concentrate nekusimba kwemagineti kuparadzaniswa, kuitira kuvandudza kunaka kwekuisa pfungwa.

Kugadzirira kwehydrofluoric acid
Hydrofluoric acid chinhu chikuru chemakemikari chigadzirwa. Hydrofluoric acid inowanikwa nekuora fluorite ne sulfuric acid, iyo inonzi sulfuric acid nzira. Inoparadza zvakanyanya uye ine zvakawanda zvakasiyana-siyana zvekushandisa. Inowanzoshandiswa kubviswa kwejecha musimbi castings, graphite ash kubvisa, Metal kuchenesa, semiconductor kugadzira, ceramic processing, etching girazi, petroleum catalysts, nezvimwe.
Fluorite ore kubvisa bvunzo
Iyo CaF2 yemukati meiyo fluorite rough concentrate inowanikwa nekuyangarara kwepasi isingawanzo muswe muBayan Obo inongori 86.17%, iyo yakasiyana chaizvo nezvinodiwa zvevanokwanisa kutarisisa zvigadzirwa. Pamusoro pe fluorite, iyo yakaomesesa concentrate zvakare ine isingawanzo pasi uye hematite. , limonite, calcite, apatite, sodium pyroxene, amphibole, biotite uye mamwe maminera. Iwo ane fatty acid sipo vaunganidzi vanoshandiswa mu fluorite flotation vane imwe yekuunganidza maitiro pamaminerari ane iron. Pakati pezvicherwa izvi zvisina kuchena, hematite, limonite, sodium pyroxene, amphibole, uye biotite zvose hazvina simba remagineti, uye zvinogona kubviswa nekuparadzaniswa kwakasimba kwemagineti kuvandudza hutano hwe fluorite concentrate.
-200 mesh fluorite coarse concentrate ine fineness ye93.50% yakaiswa muyedzo yekufananidza yekubvisa tsvina uye kucheneswa neaviri epamusoro-simba remagineti yekuparadzanisa maitiro, senge vertical ring + electromagnetic slurry yakakwira gradient magineti separator uye vertical mhete + superconducting magineti separator. .
Mukuenzanisa bvunzo yekubvisa kwakasimba magineti kusachena, zvakaonekwa kuti mamwe maminerari akadai sehematite, limonite uye biotite ane yakakwira chaiyo magineti susceptibility inogona kunyatso kubviswa nekuparadzaniswa kwakasimba kwemagineti yeringi yakamira, uye CaF2 giredhi re fluorite. kutarisisa kwakawedzera kubva pa86.17%. Ipapo maminerari ane simbi ane simba remagineti anobviswa ne electromagnetic slurry uye superconducting magineti separator, uye iyo CaF2 giredhi yefluorite concentrate inowedzerwa kusvika 93.84% uye 95.63% zvichiteerana, zvese zvichisvika FC-93 uye FC-95. quality standard. Iyo Beneficiation mhedzisiro yeinomira mhete uye electromagnetic slurry yakakwira gradient magineti separator uye yakaderera tembiricha superconducting magineti separator iri pachena, iyo inogona kupa yakavimbika tekinoroji hwaro hwekubviswa kwakasimba kwemagineti uye kucheneswa kwemaminerari akadaro.
