Purple upstart! Huate Magneto Power Yakulitsa Kukula Kwapamwamba kwa Mzere Wopangira wa Fluorite Sorting Industrialized

【Huate Mineral Processing Encyclopedia】Purple upstart! Mphamvu ya Huate Magneto Imakulitsa Kukula Kwapamwamba kwa Mzere Wopangira Fluorite Wosanja Mafakitale

Fluorite, yomwe imadziwikanso kuti fluorite, ili ndi yttrium yochuluka yotchedwa yttrium fluorite. Makristalo nthawi zambiri amakhala a cubic, octahedron, komanso ochepa rhombic dodecahedron. Monga mchere wamba, zitsanzo zina zimatha kutulutsa kuwala zikamaphwanyidwa, kutentha, kuwala kwa ultraviolet, ndi zina zotero. Sizimagwiritsidwa ntchito kawirikawiri ngati mwala wamtengo wapatali chifukwa cha kufooka kwake komanso kufewa kwake. M'mafakitale, fluorite ndiye gwero lalikulu lotulutsa ndikukonzekera zinthu zosiyanasiyana monga fluorine ndi hydrofluoric acid, ndipo zitsanzo za fluorite zokhala ndi mitundu yowala komanso mawonekedwe okongola a kristalo zingagwiritsidwe ntchito posonkhanitsa, kukongoletsa ndi kujambula.

Katundu wa Mamineral ndi Kapangidwe kake

Fluorite imapangidwa ndi CaF2, yomwe ili ndi 48.67% fluorine, 51.33% calcium, ndipo nthawi zina zinthu zosowa. Nthawi zambiri imakhala yogwirizana ndi quartz, calcite, barite ndi metal sulfide, mu granular kapena magrafts akuluakulu, nthawi zambiri yachikasu ndi yobiriwira. , buluu, wofiirira, ndi zina zotero, yopanda mtundu, vitreous luster, hardness 4, density 3.18g/cm3, yotentha kapena ya fluorescent pansi pa ultraviolet light. Fluorite sisungunuka m'madzi, imasungunuka mu sulfuric acid, phosphoric acid ndi hot hydrochloric acid, boric acid, hypochlorous acid, ndipo imatha kuchitapo kanthu pang'ono ndi maziko olimba monga potassium hydroxide ndi sodium hydroxide, yokhala ndi 1360 °C.

Madera ogwiritsira ntchito ndi zizindikiro zaukadaulo

Fluorite ili ndi halogen element fluorine, yomwe ndi chinthu chachikulu chopangira zinthu zopangidwa ndi fluorine, ndipo imagwiritsidwa ntchito kwambiri popanga zitsulo, kusungunula zitsulo zopanda chitsulo, simenti, galasi, ziwiya zadothi, ndi zina zotero chifukwa cha malo ake otsika osungunuka. Imapezeka ngati fluorite yowala komanso fluorite yopangidwa ndi craft.

Gome 1 Ntchito zazikulu za fluorite

Zofunikira pa mndandanda waukadaulo

Miyezo yamakampani opanga zitsulo imagawa zinthu za fluorite m'mitundu itatu: fluorite concentrate (FC), fluorite lump (FL) ndi fluorite fines (FF).

Gome 2 Kapangidwe ka mankhwala a fluorite concentrate

Ukadaulo Wokonza

Kupindula ndi Kuyeretsa

Mineral yomwe imagwirizana ndi fluorite ndi iyi: quartz, calcite, scheelite, apatite, cassiterite, wolframite, pyrite, sphalerite, lapis lazuli, muscovite, galena, chalcopyrite, rhodochrosite Manganese ore, dolomite, potassium feldspar, spinel, barite, ndi zina zotero. Malinga ndi kusiyana kwa makhalidwe a mchere wogwirizana mu fluorite, kulekanitsa ndi kuyeretsa kumachitika pogwiritsa ntchito flotation, magnetic learning, gravity learning ndi njira zina zopindulitsa.

①Kuyandama

Kuyandama ndiye njira yofunika kwambiri yopezera fluorite. Njira yonse ndi kusonkhanitsa mafuta acids mutatha kupukutira, ndikusankha zinthu zoyenera za fluorite concentrate kudzera munjira zosiyanasiyana zosankhira; pa mchere wa sulfide wogwirizana, Mankhwala achikasu amasankhidwa, ndipo barite, calcite, muscovite, ndi zina zotero zimalekanitsidwa ndi zoletsa.

②Kusankhidwanso - kuyandama

Pamene chitsulo chamtengo wapatali chili chochepa kapena chili ndi matupi ambiri ogwirizana, njira yophatikizana yolekanitsa mphamvu yokoka ndi kuyandama imagwiritsidwa ntchito nthawi zambiri.

③ Kulekanitsa kwa maginito - kuyandama

Ngati pali maginito ambiri achitsulo kapena ma iron oxides mu ore, cholekanitsa maginito cha drum chingagwiritsidwe ntchito kulekanitsa chitsulo champhamvu cha magnetic kapena cholekanitsa maginito cha vertical ring kuti chichotse magnetic iron oxide yofooka kenako chidutse mu flotation process; ngati pali maginito ochepa achitsulo mu ore yoyambirira, Komabe, pamene kuchuluka kwa chitsulo mu flotation fluorite concentrate kumaposa muyezo, vertical ring kapena electromagnetic slurry high gradient magnetic separator ingagwiritsidwe ntchito kuchotsa iron oxide minerals mu fluorite concentrate pogwiritsa ntchito magnetic separation yamphamvu, kuti akonze bwino concentrate.

Mphete yoziziritsa yozungulira yokhala ndi mafuta ndi madzi ophatikizika

Cholekanitsa maginito chotsika kutentha kwambiri

Cholekanitsa Magnetic cha Ng'oma

Kukonzekera kwa hydrofluoric acid

Hydrofluoric acid ndi mankhwala akuluakulu. Hydrofluoric acid imapezeka pobowola fluorite ndi sulfuric acid, njira yotchedwa sulfuric acid. Ndi yowononga kwambiri ndipo imagwiritsidwa ntchito m'njira zosiyanasiyana. Nthawi zambiri imagwiritsidwa ntchito pochotsa mchenga mu zitsulo, kuchotsa phulusa la graphite, kuyeretsa zitsulo, kupanga zinthu za semiconductor, kukonza ceramic, magalasi odulidwa, ma catalysts a petroleum, ndi zina zotero.

Mayeso ochotsera miyala ya fluorite

Kuchuluka kwa CaF2 mu fluorite rough concentrate komwe kumapezeka poyatsa nthaka yachilendo ku Bayan Obo ndi 86.17% yokha, zomwe zimasiyana kwambiri ndi zofunikira pazinthu zoyenera za concentrate. Kuphatikiza pa fluorite, rough concentrate ilinso ndi rare earth ndi hematite. , limonite, calcite, apatite, sodium pyroxene, amphibole, biotite ndi mchere wina. Sopo wosonkhanitsira mafuta omwe amagwiritsidwa ntchito poyatsa fluorite ali ndi zotsatira zina pa mchere wokhala ndi chitsulo. Pakati pa mchere wosayerawu, hematite, limonite, sodium pyroxene, amphibole, ndi biotite zonse ndi zamaginito ofooka, ndipo zimatha kuchotsedwa ndi kulekanitsidwa kwamphamvu kwa maginito kuti ziwongolere mtundu wa fluorite concentrate.

-200 mesh fluorite coarse concentrate yokhala ndi ulusi wa 93.50% idayesedwa poyerekeza kuchotsa ndi kuyeretsa zodetsedwa pogwiritsa ntchito njira ziwiri zolekanitsa maginito amphamvu kwambiri, monga mphete yolunjika + electromagnetic slurry high gradient magnetic separator ndi mphete yolunjika + superconducting magnetic separator.

Mu mayeso oyerekeza a kuchotsa kwamphamvu kwa maginito, zidapezeka kuti mchere wina monga hematite, limonite ndi biotite wokhala ndi mphamvu yayikulu ya maginito amatha kuchotsedwa bwino mwa kulekanitsa kwamphamvu kwa mphete yoyimirira, ndipo kalasi ya CaF2 ya fluorite concentrate idakulitsidwa kuchokera pa 86.17%. Kenako mchere wokhala ndi chitsulo wokhala ndi mphamvu zofooka za maginito amachotsedwa ndi electromagnetic slurry ndi superconducting magnetic separator, ndipo kalasi ya CaF2 ya fluorite concentrate imakulitsidwa kufika pa 93.84% ndi 95.63% motsatana, zonse ziwiri kufika pa mulingo wabwino wa FC-93 ndi FC-95. Zotsatira za ubwino wa vertical ring ndi electromagnetic slurry high gradient magnetic separator ndi low temperature superconducting magnetic separator ndizodziwikiratu, zomwe zingapereke maziko odalirika aukadaulo ochotsera ndi kuyeretsa kwamphamvu kwa maginito.

Mapulogalamu

Cholekanitsa maginito chozungulira chapamwamba kwambiri chimagwiritsidwa ntchito pa ntchito yolekanitsa maginito ya rare earth ku Inner Mongolia

Pulojekitiyi ikugwiritsa ntchito zida ziwiri zolekanitsa maginito za 1.7T vertical ring high gradient ndi chimodzi cholekanitsa maginito cha 5.0T low temperature superconducting, zomwe zingathandize bwino kalasi ya fluorite concentrate, kupeza bwino rare earth, ndikuwonjezera kupanga ndi kugwira ntchito bwino.

Pulojekiti yogawa maginito yothandiza dziko losaoneka bwino ku Sichuan, imagwiritsa ntchito ma seti 8 a maginito olekanitsa a 1.4T vertical ring high gradient magnetic separators kuti alekanitse ndi kubwezeretsa dziko losaoneka bwino, ndipo zotsatira zake zimakhala zabwino.
