【I-Huate Mineral Processing Encyclopedia】Isiqalo esimfusa! Amandla e-Huate Magneto aKhulisa uMgangatho oPhezulu woPhuhliso lweFluorite yokuhlela i-Industrialized Production Line

I-Fluorite, eyaziwa ngokuba yi-fluorite, ityebile kwi-yttrium ebizwa ngokuba yi-yttrium fluorite. Iikristale zihlala zi cubic, octahedron, kunye nerhombic dodecahedron encinci. Iminerali eqhelekileyo ngokwendalo, ezinye iisampulu zinokukhupha ukukhanya xa ziphantsi kongquzulwano, ukufudumeza, imisebe ye-ultraviolet, njl. Kwishishini, i-fluorite ngowona mthombo uphambili wokutsalwa kunye nokulungiswa kweekhompawundi ezahlukeneyo ezifana ne-fluorine kunye ne-hydrofluoric acid, kunye nemizekelo ye-fluorite enemibala eqaqambileyo kunye neefom ze-crystal ezintle zingasetyenziselwa ukuqokelela, ukuhlobisa kunye nokudweba ubugcisa.

Iipropati zentsimbi kunye noLwakhiwo lweziMbiwa

I-Fluorite yenziwe nge-CaF2, equlethe i-48.67% ye-fluorine, i-51.33% ye-calcium, kwaye ngamanye amaxesha izinto ezinqabileyo. Ihlala i-symbiotic kunye ne-quartz, i-calcite, i-barite kunye ne-metal sulfide, kwi-granular okanye i-aggregates enkulu, ehlala ityheli kunye neluhlaza. , blue, purple, etc., ngaphantsi kombala, i-vitreous luster, ubunzima be-4, ubuninzi be-3.18g / cm3, ishushu okanye i-fluorescent phantsi kokukhanya kwe-ultraviolet. I-Fluorite ayinyibiliki emanzini, i-soluble kwi-asidi ye-sulfuric, i-asidi ye-phosphoric kunye ne-hot hydrochloric acid, i-boric acid, i-hypochlorous acid, kwaye inokusabela kancinci kunye neziseko ezomeleleyo ezifana ne-potassium hydroxide kunye ne-sodium hydroxide, ene-melting point ye-1360 °C.

Iindawo zesicelo kunye nezalathi zobugcisa

I-Fluorite iqulethe i-halogen element fluorine, eyona nto ingundoqo ekrwada yokulungiswa kweekhompawundi ze-fluorine, kwaye isetyenziswa ngokubanzi kwi-steelmaking, ukunyibilika kwesinyithi, i-samente, iglasi, i-ceramics, njl. ngenxa yokuncibilika kwayo okuphantsi. Ifumaneka njenge-optical fluorite kunye ne-craft fluorite.

Uluhlu 1 Usetyenziso oluphambili lwefluorite

Iimfuno zesalathiso sobugcisa

Imigangatho yoshishino lweMetallurgical yohlula iimveliso zefluorite zibe ziindidi ezintathu: ifluorite concentrate (FC), iqhuma lefluorite (FL) kunye nezohlwayo zefluorite (FF).

ITekhnoloji yoLungiso

Uncedo kunye nokusulungekiswa

Iiminerali ze-symbiotic kunye ne-fluorite zezi: i-quartz, i-calcite, i-scheelite, i-apatite, i-cassiterite, i-wolframite, i-pyrite, i-sphalerite, i-lapis lazuli, i-muscovite, i-galena, i-chalcopyrite, i-rhodochrosite i-Manganese ore, i-dolomite, i-spinel ye-potassium, i-spinel felds, njl njl. kwiipropati zeeminerali ezihambelanayo kwi-fluorite, ukuhlukana kunye nokuhlanjululwa kuqhutyelwa nge-flotation, ukwahlukana kwamagnetic, ukuhlukana komxhuzulane kunye nezinye iindlela zokuzuza.

①Ukuphaphatheka

I-Flotation yeyona ndlela ibalulekileyo ye-fluorite beneficiation. Inkqubo eqhelekileyo kukuqokelela i-acids enamafutha emva kokusila, kwaye ukhethe iimveliso ze-fluorite concentrate ezisemgangathweni ngokusebenzisa iinkqubo ezininzi zokukhetha; kuba iiminerali ze-sulfide ezinxulumene nazo, iziyobisi ezityheli zikhethiwe, kunye ne-barite ehambelana nayo, i-calcite, i-muscovite, njl.

②Ukunyulwa kwakhona – ukudada

Xa umgangatho wentsimbi ekrwada uphantsi okanye unemizimba emininzi erhabaxa edityanisiweyo, inkqubo edityanisiweyo yokwahlulwa komxhuzulane kunye neflotation isetyenziswa ngokubanzi.

③ Ukwahlulwa kwemagnethi – ukudada

Xa kukho intsimbi enemagnethi okanye iioksidi zentsimbi kwintsimbi ekrwada, igubu lokwahlula imagnethi lingasetyenziselwa ukwahlula intsimbi eyomeleleyo umazibuthe okanye isahluli esithe nkqo semagnethi ukususa ioksidi yentsimbi ebuthathaka kwaye emva koko udlulele kwinkqubo yokudada; ukuba kukho iiminerali ezimbalwa zentsimbi kwintsimbi yokuqala, Nangona kunjalo, xa umxholo wesinyithi we-flotation fluorite concentrate udlula umgangatho, umsesane othe nkqo okanye i-electromagnetic slurry high gradient separator magnetic ingasetyenziselwa ukususa iiminerali ze-iron oxide kwi-fluorite concentrate ngokuhlukana okunamandla kazibuthe, ukuze kuphuculwe umgangatho wokugxila.

Ukulungiswa kwe-hydrofluoric acid

I-Hydrofluoric acid yimveliso ephambili yeekhemikhali. I-Hydrofluoric acid ifunyenwe ngokubola kwe-fluorite kunye ne-sulfuric acid, ebizwa ngokuba yi-sulfuric acid method. Idleka ngokugqithisileyo kwaye inoluhlu olubanzi losetyenziso. Ihlala isetyenziselwa ukukhutshwa kwesanti kwiintsimbi zentsimbi, ukususwa kothuthu lwegraphite, ukucocwa kwesinyithi, ukuveliswa kwe-semiconductor, ukusetyenzwa kwe-ceramic, i-etching glass, i-petroleum catalysts, njl.

Uvavanyo lokususa i-fluorite ore

Umxholo we-CaF2 we-fluorite rough concentrate efunyenwe ngokudada kumhlaba onqabileyo we-Bayan Obo yi-86.17% kuphela, eyahluke kakhulu kwiimfuno zeemveliso zengqondiso ezifanelekileyo. Ukongeza kwi-fluorite, ukugxila okurhabaxa kukwaqulethe umhlaba onqabileyo kunye ne-hematite. , i-limonite, i-calcite, i-apatite, i-sodium pyroxene, i-amphibole, i-biotite kunye nezinye iiminerali. Abaqokeleli besepha ye-asidi enamafutha asetyenziswa kwi-flotation ye-fluorite banempembelelo ethile yokuqokelela kwiiminerali ezinentsimbi. Phakathi kwezi zimbiwa ezingcolileyo, i-hematite, i-limonite, i-sodium pyroxene, i-amphibole, kunye ne-biotite zonke zibuthathaka zimagnetic, kwaye zinokususwa ngokuhlukana kwamagnetic okunamandla ukuphucula umgangatho we-fluorite concentrate.

-200 i-mesh fluorite coarse concentrate ene-fineness ye-93.50% iphantsi kovavanyo oluthelekisayo lokususa ukungcola kunye nokuhlanjululwa ngeenkqubo ezimbini zokwahlula amandla amakhulu, njengeringi ethe nkqo + i-electromagnetic slurry high gradient separator magnetic kunye neringi ethe nkqo + i-superconducting separator magnetic. .

Kuvavanyo lothelekiso lokususwa kokungcola okunamandla kazibuthe, kwafunyaniswa ukuba ezinye iiminerali ezifana nehematite, imonite kunye ne-biotite enokuchaphazeleka ngokwentelekiso ephezulu ngokwemagnethi inokususwa ngempumelelo ngokwahlukana okunamandla kwemagnethi yomsesane othe nkqo, kunye nenqanaba le-CaF2 le-fluorite. ukugxila kunyuswe ukusuka kuma-86.17%. Emva koko iiminerali ezithwele isinyithi kunye neempawu ezibuthathaka zamagnetic zisuswa yi-electromagnetic slurry kunye ne-superconducting separator magnetic, kwaye i-CaF2 grade ye-fluorite concentrate inyuswe ukuya kwi-93.84% kunye ne-95.63% ngokulandelanayo, zombini ifikelela kwi-FC-93 kunye ne-FC-95. umgangatho womgangatho. Isiphumo sokuzuza umsesane othe nkqo kunye nodaka lwe-electromagnetic slurry high gradient separator magnetic and low temperatures superconducting separator magnetic icace ngakumbi, enokubonelela ngesiseko esithembekileyo sobuchwephesha sokususwa kobumdaka obunamandla kunye nokucocwa kwezi zimbiwa.

Usetyenziso

Umsesane othe nkqo umahluli wemagnethi othe nkqo usetyenziswa kwiprojekthi yolwahlulo lwemagnethi yomhlaba kwi-Inner Mongolia.

Le projekthi ithatha i-1.7T yeringi ethe nkqo ye-1.7T yezahluli eziphakamileyo ze-gradient kunye ne-5.0T enye ye-5.0T ye-superconducting ye-superconducting separator ephantsi, enokuphucula ngokufanelekileyo ibakala lokugxila kwe-fluorite, ukufezekisa ukubuyiswa kakuhle komhlaba onqabileyo, kunye nokwandisa imveliso kunye nokusebenza kakuhle.

Iprojekthi yolwahlulo olunqabileyo lomhlaba olunamandla eSichuan, le projekthi isebenzisa iiseti ezisi-8 ze-1.4T yeringi ethe nkqo yezahluli zemagnethi zokwahlula kunye nokubuyiselwa komhlaba onqabileyo, kwaye umphumo ulungile.
