【Huate Mineral Processing Encyclopedia】Yoyambira yofiirira! Mphamvu ya Huate Magneto Imakulitsa Chitukuko Chapamwamba cha Fluorite Kusankha Mzere Wopanga Zida Zamakampani

Fluorite, yomwe imadziwikanso kuti fluorite, imakhala ndi yttrium yotchedwa yttrium fluorite. Makhiristo nthawi zambiri amakhala cubic, octahedron, ndi dodecahedron yocheperako. A mchere wamba m'chilengedwe, zitsanzo zina zimatha kutulutsa kuwala pamene zikukumana ndi mikangano, kutentha, cheza cha ultraviolet, ndi zina zotero. Sizigwiritsidwa ntchito ngati mwala wamtengo wapatali chifukwa cha brittleness ndi kufewa kwake. M'makampani, fluorite ndiye gwero lalikulu la kutulutsa ndi kukonza zinthu zosiyanasiyana monga fluorine ndi hydrofluoric acid, ndi zitsanzo za fluorite zokhala ndi mitundu yowala komanso mawonekedwe okongola a kristalo angagwiritsidwe ntchito kusonkhanitsa, kukongoletsa ndi zojambulajambula.

Katundu wa Ore ndi Kapangidwe ka Mineral

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, mumagulu ang'onoang'ono kapena akuluakulu, nthawi zambiri achikasu ndi obiriwira. , buluu, wofiirira, ndi zina zotero, zopanda mtundu, vitreous luster, kulimba 4, kachulukidwe 3.18g/cm3, kutentha kapena fulorosenti pansi pa kuwala kwa ultraviolet. Fluorite sisungunuka m'madzi, sungunuka mu sulfuric acid, phosphoric acid ndi hot hydrochloric acid, boric acid, hypochlorous acid, ndipo imatha kuchitapo kanthu pang'ono ndi maziko amphamvu monga potaziyamu hydroxide ndi sodium hydroxide, ndi malo osungunuka a 1360 ° C.

Malo ogwiritsira ntchito ndi zizindikiro zaumisiri

Fluorite ili ndi halogen element fluorine, yomwe ndizitsulo zazikulu zopangira mankhwala a fluorine, ndipo amagwiritsidwa ntchito kwambiri popanga zitsulo, zitsulo zopanda chitsulo, simenti, galasi, ceramics, etc. chifukwa cha kusungunuka kwake kochepa. Imapezeka ngati kuwala kwa fluorite ndi craft fluorite.

Table 1 Ntchito zazikulu za fluorite

Zofunikira za index yaukadaulo

Miyezo yamakampani a Metallurgical imagawa zinthu za fluorite m'mitundu itatu: fluorite concentrate (FC), fluorite lump (FL) ndi chindapusa cha fluorite (FF).

Processing Technology

Kupindula ndi Kuyeretsedwa

Minerals symbiotic ndi fluorite ndi: quartz, calcite, scheelite, apatite, cassiterite, wolframite, pyrite, sphalerite, lapis lazuli, muscovite, galena, chalcopyrite, rhodochrosite Manganese ore, dolomite, potassium spinel felds, etc. mu katundu wa mchere kugwirizana mu fluorite, kulekana ndi kuyeretsedwa ikuchitika ndi flotation, maginito kulekana, mphamvu yokoka kulekana ndi njira zina beneficiation.

①Kuyandama

Flotation ndiye njira yofunika kwambiri yopezera fluorite. Zomwe zimachitika ndikutolera mafuta acid pambuyo popera, ndikusankha mankhwala oyenerera a fluorite posankha njira zingapo; chifukwa cha mchere wa sulfide, wachikasu Mankhwala amasankhidwa, ndipo barite, calcite, muscovite, etc. amasiyanitsidwa ndi zoletsa.

②Kusankhanso - kuyandama

Ore girediyo ikakhala yotsika kapena ili ndi matupi ambiri osakanikirana, njira yophatikizira yolekanitsa mphamvu yokoka ndi kuyandama imagwiritsidwa ntchito.

③ Kupatukana kwa maginito - kuyandama

Pamene pali maginito chitsulo kapena chitsulo okusayidi ambiri mu ore, ng'oma maginito olekanitsa angagwiritsidwe ntchito kulekanitsa amphamvu maginito chitsulo kapena ofukula mphete maginito olekanitsa kuchotsa ofooka maginito okusayidi chitsulo ndiyeno kudutsa ndondomeko zoyandama; ngati pali mchere wachitsulo pang'ono mu ore choyambirira, Komabe, pamene chitsulo zili flotation fluorite maganizo kuposa muyezo, ofukula mphete kapena electromagnetic slurry mkulu gradient maginito olekanitsa angagwiritsidwe ntchito kuchotsa chitsulo okusayidi mchere mu fluorite kuganizira ndi amphamvu maginito kulekana, kuti apititse patsogolo luso la kulingalira.

Mafuta okhala ndi madzi ophatikizika kuzirala kwa mphete yowongoka yokwera kwambiri ya maginito olekanitsa

Otsika kutentha superconducting maginito olekanitsa

Drum Magnetic Separator

Kukonzekera kwa hydrofluoric acid

Hydrofluoric acid ndiye chinthu chachikulu cha mankhwala. Hydrofluoric acid imapezeka mwa kuwonongeka kwa fluorite ndi sulfuric acid, njira yotchedwa sulfuric acid. Ndizowononga kwambiri ndipo zimagwiritsidwa ntchito mosiyanasiyana. Nthawi zambiri amagwiritsidwa ntchito pochotsa mchenga muzitsulo zachitsulo, kuchotsa phulusa la graphite, kuyeretsa zitsulo, kupanga semiconductor, kukonza ceramic, magalasi a etching, zopangira mafuta, etc.

Mayeso ochotsa miyala ya fluorite

Zomwe zili mu CaF2 za fluorite rough concentrate zopezedwa ndi kuyandama kwa dothi losowa kwambiri ku Bayan Obo ndi 86.17% yokha, yomwe ili yosiyana kwambiri ndi zomwe zimafunikira pazogulitsa zoyenerera. Kuphatikiza pa fluorite, chigawo chovuta chimakhalanso ndi nthaka yosowa komanso hematite. , limonite, calcite, apatite, sodium pyroxene, amphibole, biotite ndi mchere wina. Zotolera zamafuta a sopo zomwe zimagwiritsidwa ntchito mu fluorite flotation zimakhala ndi zotsatira zosonkhanitsa pa mchere wokhala ndi chitsulo. Pakati pa mchere wodetsedwa, hematite, limonite, sodium pyroxene, amphibole, ndi biotite zonse ndi maginito ofooka, ndipo amatha kuchotsedwa ndi kupatukana kwamphamvu kwa maginito kuti apititse patsogolo khalidwe la fluorite.

-200 mauna fluorite coarse kuganizira ndi fineness wa 93.50% anayesedwa kuyerekeza kuchotsa zonyansa ndi kuyeretsedwa ndi njira ziwiri mkulu-mphamvu maginito kulekana, monga ofukula mphete + electromagnetic slurry mkulu gradient maginito olekanitsa ndi ofukula mphete + superconducting maginito olekanitsa. .

Poyerekeza mayeso amphamvu maginito zonyansa kuchotsa, anapeza kuti ena mchere monga hematite, limonite ndi biotite ndi mkulu enieni chiwopsezo maginito akhoza bwino kuchotsedwa ndi amphamvu maginito kulekana kwa ofukula mphete, ndi CaF2 kalasi ya fluorite. kusinthana kwasintha kufika +86.17%. Ndiye mchere wokhala ndi chitsulo wokhala ndi maginito ofooka amachotsedwa ndi electromagnetic slurry ndi superconducting magnetic separator, ndi CaF2 kalasi ya fluorite concentrate yawonjezeka kufika 93.84% ndi 95.63%, onse akufika FC-93 ndi FC-95. muyezo wabwino. The beneficiation zotsatira za ofukula mphete ndi electromagnetic slurry mkulu gradient maginito olekanitsa ndi kutentha otsika superconducting maginito olekanitsa ndi zoonekeratu, amene angapereke odalirika luso maziko amphamvu maginito zonyansa kuchotsa ndi kuyeretsa mchere wotere.

Mapulogalamu

Cholekanitsa champhete chokwera kwambiri chimagwiritsidwa ntchito mu projekiti yosowa yapadziko lapansi yolekanitsa maginito ku Inner Mongolia.

Ntchitoyi utenga awiri 1.7T ofukula mphete mkulu gradient maginito olekanitsa ndi mmodzi 5.0T otsika kutentha superconducting maginito olekanitsa, amene angathe bwino kusintha kalasi ya fluorite kuganizira, kukwaniritsa kuchira bwino padziko osowa, ndi kuonjezera kupanga ndi dzuwa.

Pulojekiti yapadziko lapansi yosowa kwambiri yolekanitsa maginito ku Sichuan, pulojekitiyi imagwiritsa ntchito ma seti 8 a 1.4T ofukula maginito olekanitsa maginito olekanitsa ndikubwezeretsanso dziko losowa, ndipo zotsatira zake ndi zabwino.
