I-upstart ephuzi! Amandla e-Huate Magneto Athuthukisa Ukuthuthukiswa Kwekhwalithi Ephezulu Komugqa Wokukhiqiza Osezingeni Eliphezulu Wokuhlunga I-Fluorite

【I-Huate Mineral Processing Encyclopedia】I-upstart ephuzi! Amandla e-Huate Magneto Athuthukisa Ukuthuthukiswa Kwekhwalithi Ephezulu Komugqa Wokukhiqiza Wezimboni Ohlelwe Ngohlobo Lwe-Fluorite

I-Fluorite, eyaziwa nangokuthi i-fluorite, icebile nge-yttrium ebizwa ngokuthi i-yttrium fluorite. Amakristalu avame ukuba yi-cubic, i-octahedron, kanye ne-dodecahedron encane kakhulu. Njengeminerali evamile ngokwemvelo, amanye amasampula angakhipha ukukhanya lapho ehlushwa ukungqubuzana, ukushisa, imisebe ye-ultraviolet, njll. Ayivame ukusetshenziswa njengegugu ngenxa yokuba buthakathaka nokuthamba kwayo. Embonini, i-fluorite iwumthombo oyinhloko wokukhishwa nokulungiswa kwamakhemikhali ahlukahlukene njenge-fluorine ne-hydrofluoric acid, futhi amasampula e-fluorite anemibala egqamile kanye nezinhlobo ezinhle zekristalu angasetshenziswa ekuqoqweni, ekuhlobiseni nasekuqopheni ubuciko.

Izakhiwo Zensimbi Eyigugu kanye Nesakhiwo Sezimbiwa

I-Fluorite yakhiwe yi-CaF2, equkethe i-fluorine engu-48.67%, i-calcium engu-51.33%, futhi ngezinye izikhathi izakhi ezingavamile. Ivame ukuba yingxenye ye-quartz, i-calcite, i-barite kanye ne-metal sulfide, kuma-granular noma ama-massive aggregates, ngokuvamile aphuzi futhi aluhlaza okotshani. , eluhlaza okwesibhakabhaka, onsomi, njll., ayinambala kangako, i-vitreous luster, ubulukhuni 4, ubuningi obungu-3.18g/cm3, ifudumele noma i-fluorescent ngaphansi kokukhanya kwe-ultraviolet. I-Fluorite ayincibiliki emanzini, incibilika ku-sulfuric acid, i-phosphoric acid kanye ne-hot hydrochloric acid, i-boric acid, i-hypochlorous acid, futhi ingasabela kancane ngezisekelo eziqinile njenge-potassium hydroxide kanye ne-sodium hydroxide, enephuzu lokuncibilika elingu-1360 °C.

Izindawo zokusetshenziswa kanye nezinkomba zobuchwepheshe

I-Fluorite iqukethe i-halogen element fluorine, okuyizinto eziyinhloko zokusetshenziswa zokulungiselela amakhemikhali e-fluorine, futhi isetshenziswa kabanzi ekwenzeni insimbi, ukuncibilikisa insimbi engena-ferrous, usimende, ingilazi, izinto zobumba, njll. ngenxa yezinga layo eliphansi lokuncibilika. Itholakala njenge-optical fluorite kanye ne-craft fluorite.

Ithebula 1 Ukusetshenziswa okuyinhloko kwe-fluorite

Izidingo zenkomba yobuchwepheshe

Izindinganiso zemboni ye-Metallurgical zihlukanisa imikhiqizo ye-fluorite ibe izinhlobo ezintathu: i-fluorite concentrate (FC), i-fluorite lump (FL) kanye ne-fluorite fines (FF).

Ubuchwepheshe Bokucubungula

Ukuzuza Nokuhlanzwa

Amaminerali ahambisana ne-fluorite yilawa: 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-potassium feldspar, i-spinel, i-barite, njll. Ngokusho komehluko wezakhiwo zamaminerali ahlobene ku-fluorite, ukuhlukaniswa nokuhlanzwa kwenziwa nge-flotation, ukuhlukaniswa kwamagnetic, ukuhlukaniswa kwamandla adonsela phansi kanye nezinye izindlela zokuzuza.

①Ukuntanta

Ukuntanta kuyindlela ebaluleke kakhulu yokwenza i-fluorite ibe ngcono. Inqubo evamile ukuqoqa ama-fatty acid ngemva kokugaya, bese ukhetha imikhiqizo efanelekile yokugxila kwe-fluorite ngezinqubo eziningi zokukhetha; amaminerali e-sulfide ahlobene, kukhethwa izidakamizwa eziphuzi, kanti i-barite ehlobene, i-calcite, i-muscovite, njll. ihlukaniswa yizithibi.

②Ukukhethwa kabusha – ukuntanta

Uma izinga le-ore liphansi noma liqukethe imizimba eminingi ehlangene, inqubo ehlanganisiwe yokuhlukaniswa kwamandla adonsela phansi kanye nokuntanta ngokuvamile isetshenziswa.

③ Ukuhlukaniswa kwamagnetic - ukuntanta

Uma kunezinhlobo eziningi ze-magnetic iron noma i-iron oxides ku-ore, i-drum magnetic separator ingasetshenziswa ukuhlukanisa i-magnetic iron enamandla noma i-vertical ring magnetic separator ukususa i-magnetic iron oxide ebuthakathaka bese idlula enkambisweni yokuntanta; uma kunezinhlobo ezimbalwa ze-iron minerals ku-ore yokuqala, Kodwa-ke, lapho okuqukethwe kwensimbi kwe-flotation fluorite concentrate kudlula i-standard ring noma i-electromagnetic slurry high gradient magnetic separator ingasetshenziswa ukususa i-iron oxide minerals ku-fluorite concentrate ngokuhlukana okunamandla kwe-magnetic, ukuze kuthuthukiswe ikhwalithi ye-concentrate.

Ukulungiswa kwe-hydrofluoric acid

I-Hydrofluoric acid iwumkhiqizo oyinhloko wamakhemikhali. I-Hydrofluoric acid itholakala ngokubolisa i-fluorite nge-sulfuric acid, okubizwa ngokuthi indlela ye-sulfuric acid. Igqwala kakhulu futhi inezindlela eziningi zokusetshenziswa. Ivame ukusetshenziselwa ukususa isihlabathi ekubunjweni kwensimbi, ekususweni komlotha we-graphite, ekuhlanzweni kwensimbi, ekukhiqizweni kwe-semiconductor, ekucutshungulweni kwe-ceramic, etching glass, kuma-catalysts e-petroleum, njll.

Ukuhlolwa kokususwa kwe-Fluorite ore

Okuqukethwe kwe-CaF2 kwe-fluorite rough concentrate etholakala ngokuntanta kwe-rare earth tailing e-Bayan Obo kungu-86.17% kuphela, okuhluke kakhulu ezidingweni zemikhiqizo efanelekile yokugxila. Ngaphezu kwe-fluorite, i-rough concentrate iqukethe ne-rare earth kanye ne-hematite. , i-limonite, i-calcite, i-apatite, i-sodium pyroxene, i-amphibole, i-biotite namanye amaminerali. Abaqoqi bensipho ye-fatty acid esetshenziswa ekuntanta kwe-fluorite banomphumela othile wokuqoqa amaminerali aphethe insimbi. Phakathi kwala maminerali angcolile, i-hematite, i-limonite, i-sodium pyroxene, i-amphibole, kanye ne-biotite konke kunamandla okudonsa, futhi kungasuswa ngokuhlukaniswa okunamandla kokudonsa ukuze kuthuthukiswe ikhwalithi yokudonsa kwe-fluorite.

I-concentrate ye-fluorite engu-200 ene-fineness engu-93.50% yahlolwa ngokuqhathanisa ukususwa kokungcola kanye nokuhlanzwa ngezinqubo ezimbili zokuhlukanisa amandla kazibuthe aphezulu, njengendandatho eqondile + i-electromagnetic slurry high gradient magnetic separator kanye nendandatho eqondile + i-superconducting magnetic separator.

Ekuhlolweni kokuqhathanisa kokususwa kokungcola okunamandla kwe-magnetic, kwatholakala ukuthi amanye amaminerali afana ne-hematite, i-limonite kanye ne-biotite anokuzwela okukhulu kwe-magnetic okungasuswa ngempumelelo ngokuhlukaniswa okunamandla kwe-magnetic ring eqondile, kanti izinga le-CaF2 le-fluorite concentrate landa kusuka ku-86.17%. Khona-ke amaminerali aphethe insimbi anezakhiwo ezibuthakathaka ze-magnetic asuswa nge-electromagnetic slurry kanye ne-superconducting magnetic separator, kanti izinga le-CaF2 le-fluorite concentrate landa laya ku-93.84% kanye no-95.63% ngokulandelana, kokubili kufinyelela ezingeni lekhwalithi le-FC-93 kanye ne-FC-95. Umphumela wokuzuza we-vertical ring kanye ne-electromagnetic slurry high gradient magnetic separator kanye ne-low temperature superconducting magnetic separator usobala kakhulu, okunganikeza isisekelo sobuchwepheshe esithembekile sokususwa kokungcola okunamandla kwe-magnetic kanye nokuhlanzwa kwamaminerali anjalo.

Izicelo

Isihlukanisi sikamazibuthe esinomugqa oqondile esinomugqa ophezulu sisetshenziswa kuphrojekthi yokuhlukanisa umazibuthe ongavamile e-Inner Mongolia

Le phrojekthi isebenzisa izihlukanisi ezimbili ze-magnetic ring vertical ring high gradient magnetic separator ezimbili kanye nesihlukanisi esisodwa se-magnetic superconducting magnetic 5.0T esinokushisa okuphansi, esingathuthukisa ngempumelelo izinga le-fluorite concentrate, sifinyelele ukubuyiswa okuhle komhlaba ongavamile, futhi sandise ukukhiqizwa nokusebenza kahle.

Iphrojekthi yokuhlukanisa amandla kagesi aqinile eSichuan, esebenzisa amasethi ayi-8 ama-separator kagesi aqondile angu-1.4T ukuze ahlukanise futhi abuyisele umhlaba ongavamile, futhi umphumela muhle.
