Fluorite, tseem hu ua fluorite, yog nplua nuj nyob rau hauv yttrium hu ua yttrium fluorite. Cov crystals feem ntau yog cubic, octahedron, thiab tsawg dua rhombic dodecahedron. Ib qho ntxhia hauv cov xwm txheej, qee cov qauv tuaj yeem tawm lub teeb thaum raug kev sib txhuam, cua sov, hluav taws xob ultraviolet, thiab lwm yam. Nws tsis yog feem ntau siv los ua lub pov haum vim nws cov brittleness thiab softness. Hauv kev lag luam, fluorite yog lub hauv paus tseem ceeb rau kev tshem tawm thiab kev npaj ntawm ntau yam sib xyaw xws li fluorine thiab hydrofluoric acid, thiab cov qauv fluorite nrog cov xim ci thiab zoo nkauj siv lead ua tuaj yeem siv rau kev sau, kho kom zoo nkauj thiab kos duab kos duab.

Ore Properties thiab Mineral Structure

Fluorite yog tsim los ntawm CaF2, uas muaj 48.67% fluorine, 51.33% calcium, thiab qee zaum cov khoom tsis tshua muaj. Nws yog feem ntau symbiotic nrog quartz, calcite, barite thiab hlau sulfide, nyob rau hauv granular los yog loj aggregates, feem ntau daj thiab ntsuab. , xiav, ntshav, thiab lwm yam., tsis muaj xim, vitreous luster, hardness 4, ntom 3.18g / cm3, rhuab los yog fluorescent nyob rau hauv ultraviolet lub teeb. Fluorite yog insoluble nyob rau hauv dej, soluble nyob rau hauv sulfuric acid, phosphoric acid thiab kub hydrochloric acid, boric acid, hypochlorous acid, thiab muaj peev xwm hnov ​​me ntsis nrog muaj zog bases xws li poov tshuaj hydroxide thiab sodium hydroxide, nrog ib tug melting point ntawm 1360 ° C.

Daim ntawv thov thaj chaw thiab cov cim qhia

Fluorite muaj cov khoom siv halogen fluorine, uas yog cov khoom siv tseem ceeb rau kev npaj cov tshuaj fluorine, thiab yog siv dav hauv steelmaking, non-ferrous hlau smelting, cement, iav, ceramics, thiab lwm yam vim nws tsis tshua muaj melting point. Muaj li optical fluorite thiab khoom siv fluorite.

Kev Siv Tshuab

Kev pab thiab Purification

Minerals symbiotic nrog fluorite yog: quartz, calcite, scheelite, apatite, cassiterite, wolframite, pyrite, sphalerite, lapis lazuli, muscovite, galena, chalcopyrite, rhodochrosite Manganese ore, dolomite, potassium feldspar, thiab lwm yam. Nyob rau hauv cov khoom ntawm cov minerals txuam nyob rau hauv fluorite, kev sib cais thiab purification yog nqa tawm los ntawm flotation, sib nqus sib cais, lub ntiajteb txawj nqus sib cais thiab lwm yam beneficiation txoj kev.

① Flotation

Flotation yog txoj kev tseem ceeb tshaj plaws ntawm kev siv tshuaj fluorite. Cov txheej txheem dav dav yog txhawm rau sau cov roj fatty acids tom qab sib tsoo, thiab xaiv cov khoom tsim nyog fluorite mloog zoo los ntawm ntau txoj kev xaiv; rau cov kab mob sulfide txuam nrog, cov tshuaj daj yog xaiv, thiab cov kab mob sib txuas, calcite, muscovite, thiab lwm yam yog cais los ntawm inhibitors.

②Kev xaiv tsa - flotation

Thaum cov ore qib qis los yog muaj ntau cov coarse conjoined lub cev, cov txheej txheem ua ke ntawm lub ntiajteb txawj nqus sib cais thiab flotation feem ntau yog siv.

③ Sib nqus sib cais - flotation

Thaum muaj ntau cov hlau nplaum hlau los yog hlau oxides nyob rau hauv cov ore, lub nruas sib nqus sib nqus yuav siv tau los cais cov hlau nplaum muaj zog los yog lub nplhaib ntsug hlau nplaum cais kom tshem tawm cov hlau nplaum tsis muaj zog hlau oxide thiab tom qab ntawd mus rau hauv cov txheej txheem flotation; Yog hais tias muaj ob peb hlau minerals nyob rau hauv thawj ore, Txawm li cas los xij, thaum cov ntsiab lus hlau ntawm flotation fluorite mloog zoo tshaj tus qauv, lub nplhaib ntsug lossis electromagnetic slurry siab gradient sib nqus sib nqus sib cais tuaj yeem siv los tshem tawm cov hlau oxide minerals hauv fluorite mloog zoo los ntawm kev sib nqus sib nqus, thiaj li txhim kho qhov zoo ntawm concentrate.

Kev npaj ntawm hydrofluoric acid

Hydrofluoric acid yog cov khoom siv tshuaj lom neeg. Hydrofluoric acid yog tau los ntawm decomposing fluorite nrog sulfuric acid, thiaj li hu ua sulfuric acid txoj kev. Nws yog corrosive heev thiab muaj ntau yam kev siv. Nws yog feem ntau siv rau cov xuab zeb tshem tawm hauv cov hlau castings, graphite tshauv tshem tawm, hlau tu, semiconductor manufacturing, ceramic ua, etching iav, roj av catalysts, thiab lwm yam.

Kev ntsuam xyuas kev tshem tawm fluorite ore

CaF2 cov ntsiab lus ntawm fluorite ntxhib concentrate tau los ntawm flotation ntawm lub ntiaj teb tsis tshua muaj tailing nyob rau hauv Bayan Obo tsuas yog 86.17%, uas yog heev txawv los ntawm cov yuav tsum tau rau tsim nyog concentrate cov khoom. Ntxiv nrog rau fluorite, qhov ntxhib concentrate kuj muaj tsawg lub ntiaj teb thiab hematite. , limonite, calcite, apatite, sodium pyroxene, amphibole, biotite thiab lwm yam minerals. Cov tshuaj ntxuav tes fatty acid siv nyob rau hauv fluorite flotation muaj ib qho kev sau los ntawm cov khoom siv hlau. Ntawm cov impurity cov zaub mov no, hematite, limonite, sodium pyroxene, amphibole, thiab biotite yog txhua yam tsis muaj zog hlau nplaum, thiab tuaj yeem raug tshem tawm los ntawm kev sib nqus sib nqus kom zoo dua fluorite concentrate.

-200 mesh fluorite coarse concentrate nrog fineness ntawm 93.50% tau raug rau kev sib piv ntawm impurity tshem tawm thiab purification los ntawm ob tug high-strength sib nqus sib cais txheej txheem, xws li ntsug nplhaib + electromagnetic slurry high gradient sib nqus sib nqus separator thiab ntsug nplhaib + superconducting sib nqus sib nqus. .

Nyob rau hauv kev sib piv kev ntsuam xyuas ntawm muaj zog sib nqus impurity tshem tawm, nws tau pom tias ib co minerals xws li hematite, limonite thiab biotite nrog ib tug tshwj xeeb sib nqus susceptibility yuav raug tshem tawm zoo los ntawm ib tug muaj zog sib nqus sib cais ntawm lub ntsug nplhaib, thiab CaF2 qib ntawm fluorite. concentration tau nce los ntawm 86.17%. Tom qab ntawd cov hlau-cov kabmob uas muaj cov khoom sib nqus tsis muaj zog raug tshem tawm los ntawm electromagnetic slurry thiab superconducting magnetic separator, thiab CaF2 qib ntawm fluorite concentrate yog nce mus rau 93.84% thiab 95.63% feem, ob qho tib si ncav cuag FC-93 thiab FC-95. tus qauv zoo. Cov txiaj ntsig zoo ntawm lub nplhaib ntsug thiab electromagnetic slurry siab gradient magnetic separator thiab qis kub superconducting magnetic separator yog qhov pom tseeb dua, uas tuaj yeem muab cov txheej txheem txhim khu kev qha rau lub zog sib nqus impurity tshem tawm thiab purification ntawm cov zaub mov.
