【I-Huate Mineral Processing Encyclopedia】Isiqalo esiphephuli! I-Huate Magneto Power Ithuthukisa Ukuthuthukiswa Kwekhwalithi Ephezulu Yomugqa Wokukhiqiza I-Fluorite Wokuhlunga Izimboni

I-fluorite, eyaziwa nangokuthi i-fluorite, inothile nge-yttrium ebizwa ngokuthi i-yttrium fluorite. Amakristalu avame ukuba yi-cubic, octahedron, kanye ne-rhombic dodecahedron encane. Iminerali evamile ngokwemvelo, amanye amasampuli angakhipha ukukhanya lapho ebhekene nokungqubuzana, ukushisisa, imisebe ye-ultraviolet, njll. Ayivamisile ukusetshenziswa njengetshe eliyigugu ngenxa yokuqina nokuthambile kwayo. Embonini, i-fluorite iwumthombo oyinhloko wokukhishwa nokulungiswa kwezinhlanganisela ezihlukahlukene ezifana ne-fluorine ne-hydrofluoric acid, kanye nezibonelo ze-fluorite ezinemibala egqamile kanye namafomu amahle e-crystal angasetshenziswa ekuqoqweni, ukuhlobisa nokudweba ubuciko.

Izakhiwo ze-Ore kanye nesakhiwo samaminerali

I-Fluorite yakhiwe i-CaF2, equkethe i-fluorine engu-48.67%, i-calcium engu-51.33%, futhi ngezinye izikhathi izakhi ezingavamile. Ngokuvamile i-symbiotic ne-quartz, i-calcite, i-barite ne-metal sulfide, ngama-granular noma ama-aggregate amakhulu, ngokuvamile aphuzi futhi aluhlaza. , okuluhlaza okwesibhakabhaka, okunsomi, njll., angenambala kancane, i-vitreous luster, ubulukhuni 4, ukuminyana okungu-3.18g/cm3, ukushisisa noma i-fluorescent ngaphansi kokukhanya kwe-ultraviolet. I-fluorite ayincibiliki emanzini, incibilika ku-sulfuric acid, i-phosphoric acid ne-hot hydrochloric acid, i-boric acid, i-hypochlorous acid, futhi ingasabela kancane ngezisekelo eziqinile njenge-potassium hydroxide ne-sodium hydroxide, enephuzu lokuncibilika elingu-1360 °C.

Izindawo zokufaka izicelo kanye nezinkomba zobuchwepheshe

I-fluorite iqukethe i-halogen element i-fluorine, okuyizinto ezingavuthiwe eziyinhloko zokulungiswa kwezinhlanganisela ze-fluorine, futhi isetshenziswa kakhulu ekwenzeni insimbi, ukuncibilikisa insimbi engeyona insimbi, usimende, ingilazi, izitsha zobumba, njll. ngenxa yokuncibilika kwayo okuphansi. Itholakala njenge-optical fluorite kanye ne-craft fluorite.

Ithebula 1 Ukusetshenziswa okuyinhloko kwe-fluorite

Izidingo zenkomba yobuchwepheshe

Amazinga emboni ye-Metallurgical ahlukanisa imikhiqizo ye-fluorite ibe yizinhlobo ezintathu: i-fluorite concentrate (FC), i-fluorite lump (FL) kanye nezinhlawulo ze-fluorite (FF).

Ithebula 2 Ukwakheka kwamakhemikhali kwe-fluorite concentrate

Ukucubungula Ubuchwepheshe

Ukuhlomula nokuhlanzwa

Amaminerali e-symbiotic ane-fluorite yilezi: 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 felds ye-potassium. ezindaweni zamaminerali ahlotshaniswa ne-fluorite, ukuhlukaniswa nokuhlanzwa kwenziwa nge-flotation, ukuhlukaniswa kwamagnetic, ukuhlukaniswa kwamandla adonsela phansi kanye nezinye izindlela zokuzuza.

①Ukuntanta

I-Flotation iyindlela ebaluleke kakhulu yokuzuza kwe-fluorite. Inqubo evamile iwukuqoqa ama-fatty acids ngemva kokugaya, bese ukhetha imikhiqizo yokugxilisa ingqondo ye-fluorite ngezinqubo eziningi zokukhetha; ngenxa yamaminerali e-sulfide ahlobene, i-yellow Drugs ikhethiwe, futhi i-barite ehambisanayo, i-calcite, i-muscovite, njll. ihlukaniswa ngama-inhibitors.

②Ukukhethwa kabusha - ukuntanta

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

③ Ukuhlukaniswa kwamagnetic - ukuntanta

Uma kunama-iron kazibuthe amaningi noma ama-iron oxides ensimbi, isihlukanisi sikazibuthe sesigubhu singasetshenziswa ukuhlukanisa insimbi kazibuthe eqinile noma isihlukanisi esiyindandatho esime mpo sikhipha i-iron oxide enozibuthe ebuthaka bese sidlula inqubo yokuntanta; uma kukhona amaminerali ensimbi ambalwa ku-ore yasekuqaleni, Nokho, lapho okuqukethwe kwensimbi ye-flotation fluorite concentrate idlula izinga, indandatho eqondile noma i-electromagnetic slurry high gradient isihlukanisi kazibuthe singasetshenziswa ukususa amaminerali e-iron oxide ekugxilweni kwe-fluorite ngokuhlukana okunamandla kazibuthe, ukuze kuthuthukiswe izinga lokugxilisa ingqondo.

Ukulungiswa kwe-hydrofluoric acid

I-Hydrofluoric acid ingumkhiqizo wamakhemikhali oyinhloko. I-Hydrofluoric acid itholakala ngokubola kwe-fluorite nge-sulfuric acid, okubizwa ngokuthi indlela ye-sulfuric acid. Iyagqwala ngokwedlulele futhi inezinhlobonhlobo zokusetshenziswa. Kuvame ukusetshenziselwa ukukhishwa kwesihlabathi ekufakweni kwensimbi, ukukhishwa komlotha we-graphite, ukuhlanza insimbi, ukukhiqizwa kwe-semiconductor, ukucubungula kwe-ceramic, ingilazi yokufaka ingilazi, ama-catalysts e-petroleum, njll.

Ukuhlolwa kokukhipha i-fluorite ore

Okuqukethwe kwe-CaF2 kwe-fluorite rough concentrate etholwe ngokuntanta komsila womhlaba ongavamile e-Bayan Obo ingama-86.17% kuphela, okuhluke kakhulu ezimfuneko zemikhiqizo yokugxilisa ingqondo efanelekayo. Ngaphezu kwe-fluorite, i-concentrate eqinile iqukethe umhlaba ongavamile kanye ne-hematite. , i-limonite, i-calcite, i-apatite, i-sodium pyroxene, i-amphibole, i-biotite namanye amaminerali. Iziqoqi zensipho ene-acid enamafutha asetshenziswa ku-fluorite flotation inomphumela wokuqoqwa okuthile kumaminerali anensimbi. Phakathi kwalawa maminerali angcolile, i-hematite, i-limonite, i-sodium pyroxene, i-amphibole, ne-biotite zonke ziyizibuthe ezibuthakathaka, futhi zingasuswa ngokuhlukana okunamandla kazibuthe ukuze kuthuthukiswe izinga lokugxila kwe-fluorite.

-I-200 mesh fluorite coarse concentrate enobuhle obungu-93.50% ibe ngaphansi kovivinyo oluqhathaniswayo lokususwa kokungcola kanye nokuhlanzwa ngezinqubo ezimbili eziqinile zokuhlukanisa kazibuthe, njengendandatho eqondile + i-electromagnetic slurry high gradient separator magnetic kanye neringi eqondile + isihlukanisi kazibuthe esinamandla amakhulu. .

Esivivinyweni sokuqhathanisa sokususwa kokungcola okuqinile kazibuthe, kutholwe ukuthi amanye amaminerali afana ne-hematite, i-limonite ne-biotite anokuthambekela okukhethekile kazibuthe angasuswa ngempumelelo ngokuhlukana okuqinile kazibuthe kwendandatho eqondile, kanye nebanga le-CaF2 le-fluorite. ukugxila kukhuphuke kusuka ku-86.17%. Khona-ke amaminerali ane-iron anezakhiwo ezinozibuthe ezibuthakathaka asuswa yi-electromagnetic slurry kanye ne-superconducting separator kazibuthe, futhi izinga le-CaF2 le-fluorite concentrate likhuphuka laya ku-93.84% kanye nama-95.63% ngokulandelanayo, womabili afinyelela ku-FC-93 ne-FC-95. izinga lekhwalithi. Umthelela wokuzuza wendandatho eqondile kanye ne-electromagnetic slurry high gradient separator kazibuthe kanye nesihlukanisi esinokushisa esiphansi se-superconducting magnetic sisobala kakhudlwana, esinganikeza isisekelo esithembekile sobuchwepheshe sokususwa kokungcola okunamandla kazibuthe kanye nokuhlanzwa kwamaminerali anjalo.

Izinhlelo zokusebenza

Isihlukanisi esime mpo se-gradient high gradient magnetic sisetshenziswa kuphrojekthi yokuhlukanisa kazibuthe yomhlaba engavamile e-Inner Mongolia

Le phrojekthi yamukela izihlukanisi ezimbili eziqondile eziyi-1.7T ezime mpo ze-gradient high gradient magnetic kanye ne-5.0T eyodwa yokushisa ephansi ye-superconducting separator, engathuthukisa ngempumelelo izinga lokugxila kwe-fluorite, ukuzuza ukululama okuhle komhlaba ongavamile, nokwandisa ukukhiqizwa nokusebenza kahle.

Iphrojekthi yokuhlukanisa kazibuthe eqinile eyivelakancane ezuzisa umhlaba eSichuan, iphrojekthi isebenzisa amasethi ayi-8 wendandatho eqondile engu-1.4T yezihlukanisi ezinozibuthe eziphakeme kakhulu zokuhlukanisa nokubuyisela umhlaba ongavamile, futhi umphumela muhle.
