Processing Technology
Beneficiation uye Kucheneswa
Minerals symbiotic ne fluorite ndezvi: quartz, calcite, scheelite, apatite, cassiterite, wolframite, pyrite, sphalerite, lapis lazuli, muscovite, galena, chalcopyrite, rhodochrosite Manganese ore, dolomite, potassium spinel felds, etc. mune zvimiro zvezvicherwa zvakabatana mufluorite, kupatsanurwa uye kucheneswa kunoitwa neflotation, kupatsanurwa kwemagineti, kupatsanurwa kwegiravhiti uye dzimwe nzira dzekubatsira.
① Flotation
Flotation ndiyo inonyanya kukosha nzira yefluorite 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 mizhinji miviri yakakasharara yakabatana, iyo yakasanganiswa maitiro ekuparadzaniswa kwegiravhiti uye flotation inowanzo shandiswa.
③ Magnetic kupatsanurwa - flotation
Kana paine akawanda magineti iron kana iron okisidhi mu ore, dhiramu remagineti separator rinogona kushandiswa kupatsanura simba remagineti iron kana vertical ringi yemagineti separator kubvisa iyo isina simba remagineti iron oxide uye yobva yaenda kuburikidza nekuyangarara maitiro;kana paine mashoma emaminerari esimbi mune yepakutanga ore, Zvisinei, kana iyo iron yemukati yeflotation fluorite concentrate inopfuura mwero, vertical ring kana electromagnetic slurry high gradient magnetic separator inogona kushandiswa kubvisa iron oxide minerals in fluorite concentrate by strong magnetic separation, 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 huwandu hwakawanda hwekushandisa.Inowanzoshandiswa kubviswa kwejecha musimbi castings, graphite ash kubvisa, Metal kuchenesa, semiconductor kugadzira, ceramic kugadzirisa, 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 mhedzisiro pamaminerari ane iron.Pakati pemaminerari aya asina 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 tsvina, zvakaonekwa kuti mamwe maminerari akadai sehematite, limonite uye biotite ane yakakwira chaiyo magineti susceptibility anogona kubviswa zvinobudirira nekuparadzaniswa kwakasimba kwemagineti yemhete yakatwasuka, uye CaF2 giredhi re fluorite. kutarisisa kwakawedzera kubva pa86.17%.Ipapo zvicherwa zvine simbi zvine simba remagineti zvimiro zvinobviswa 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.
Applications
Vertical mhete yakakwira gradient magineti separator inoshandiswa mune isingawanzo pasi magineti yekuparadzanisa chirongwa muInner Mongolia.
Iyo purojekiti inotora maviri 1.7T yakatwasuka mhete yakakwira gradient magineti separators uye imwe 5.0T yakaderera tembiricha superconducting magineti separator, iyo inogona zvinobudirira kuvandudza giredhi re fluorite concentrate, kuwana kupora kwakanaka kwepasi isingawanzo, uye kuwedzera kugadzirwa uye kushanda nesimba.
Iyo isingawanzo kubatsiridza pasi yakasimba magineti yekuparadzanisa purojekiti muSichuan, chirongwa ichi chinoshandisa masere seti e1.4T yakatwasuka mhete yakakwira magineti yekuparadzanisa uye kudzoreredza kwepasi isingawanzo, uye mhedzisiro yacho yakanaka.
