【I-Huate Mineral Processing Encyclopedia】I-Purple upstart! Amandla e-Huate Magneto Akhuthaza Uphuhliso Oluphezulu Lomgca Wemveliso Osezimbonini Oyi-Fluorite Sorting

I-Fluorite, eyaziwa ngokuba yi-fluorite, ityebile kwi-yttrium ebizwa ngokuba yi-yttrium fluorite. Iikristale zihlala ziyi-cubic, i-octahedron, kunye ne-dodecahedron encinci. Njengeminerali eqhelekileyo kwindalo, ezinye iisampulu zinokukhupha ukukhanya xa ziphantsi kokungqubana, ukufudumeza, imitha ye-ultraviolet, njl. Ayisetyenziswa rhoqo njengelitye elinqabileyo ngenxa yokuba buthathaka kwaye ithambile. Kwishishini, i-fluorite ngumthombo ophambili wokukhupha nokulungiselela iikhompawundi ezahlukeneyo ezifana ne-fluorine kunye ne-hydrofluoric acid, kwaye iisampuli ze-fluorite ezinemibala eqaqambileyo kunye neefom zekristale ezintle zingasetyenziselwa ukuqokelela, ukuhombisa kunye nobugcisa bokuzoba.

Iipropati ze-ore kunye nolwakhiwo lwezimbiwa

I-Fluorite yenziwe yi-CaF2, equlethe i-48.67% ye-fluorine, i-51.33% ye-calcium, kwaye ngamanye amaxesha izinto ezinqabileyo. Idla ngokuba yi-symbiotic kunye ne-quartz, i-calcite, i-barite kunye ne-metal sulfide, kwii-granular okanye kwi-massive aggregates, idla ngokuba yi-yellow ne-green. , eluhlaza okwesibhakabhaka, emfusa, njl.njl., ayinambala ingako, ayikhazimli kakuhle, i-vitreous luster, ubunzima 4, uxinano 3.18g/cm3, ishushu okanye i-fluorescent phantsi kokukhanya kwe-ultraviolet. I-Fluorite ayinyibiliki emanzini, inyibilika kwi-sulfuric acid, i-phosphoric acid kunye ne-hydrochloric acid eshushu, i-boric acid, i-hypochlorous acid, kwaye inokusabela kancinci kwiziseko ezinamandla ezifana ne-potassium hydroxide kunye ne-sodium hydroxide, eneqondo lokunyibilika eliyi-1360 °C.

Iindawo zokusetyenziswa kunye nezalathisi zobugcisa

I-Fluorite iqulethe i-halogen element fluorine, eyiyeyona nto iphambili ekulungiseleleni iikhompawundi ze-fluorine, kwaye isetyenziswa kakhulu ekwenzeni intsimbi, ukunyibilikisa isinyithi esingena-ferrous, isamente, iglasi, iiseramikhi, njl.njl. ngenxa yokuba iphantsi kakhulu ekunyibilikeni. Ifumaneka njenge-optical fluorite kunye ne-craft fluorite.

Itheyibhile 1 Ukusetyenziswa okuphambili kwe-fluorite

Iimfuno zesalathiso sobugcisa

Imigangatho yoshishino lwesinyithi yahlulahlula iimveliso ze-fluorite zibe ziintlobo ezintathu: i-fluorite concentrate (FC), i-fluorite lump (FL) kunye ne-fluorite fines (FF).

Itheyibhile 2 Ukwakheka kweekhemikhali ze-fluorite concentrate

Itekhnoloji yokucubungula

Ukuzuza kunye nokuHlambulula

Iiminerali ezisebenzisana nefluorite 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-potassium feldspar, i-spinel, i-barite, njl. Ngokweepropati ezahlukeneyo zeeminerali ezinxulumene ne-fluorite, ukwahlukana kunye nokuhlanjululwa kwenziwa ngokutyibilika, ukwahlukana kwemagnethi, ukwahlukana komxhuzulane kunye nezinye iindlela zokuzuza.

①Ukudada

Ukutyibilika kwe-fluorite yeyona ndlela ibalulekileyo yokwenza i-fluorite ibe mnandi. Inkqubo eqhelekileyo kukuqokelela ii-fatty acids emva kokugaywa, nokukhetha iimveliso ze-fluorite concentrate ezifanelekileyo ngokusebenzisa iinkqubo ezininzi zokukhetha; kwiiminerali ze-sulfide ezinxulumene nazo, kukhethwa amayeza atyheli, kwaye i-barite enxulumene nazo, i-calcite, i-muscovite, njl.njl. zahlulwe zizithinteli.

②Ukukhethwa kwakhona – ukutyibilika

Xa umgangatho we-ore uphantsi okanye unemizimba emininzi edibeneyo, inkqubo edibeneyo yokwahlulwa kwamandla omhlaba kunye nokuqengqeleka kwe-flotation idla ngokusetyenziswa.

③ Ukwahlulwa kwemagnethi – ukudada

Xa kukho i-magnetic iron okanye i-iron oxides ezininzi kwi-ore, i-drum magnetic separator ingasetyenziselwa ukwahlula i-magnetic iron enamandla okanye i-vertical ring magnetic separator ukususa i-weak magnetic iron oxide ize idlule kwinkqubo ye-flotation; ukuba kukho i-iron minerals ezimbalwa kwi-ore yokuqala, Nangona kunjalo, xa umxholo we-iron kwi-flotation fluorite concentrate udlula umgangatho oqhelekileyo, i-vertical ring okanye i-electromagnetic slurry high gradient magnetic separator ingasetyenziselwa ukususa i-iron oxide minerals kwi-fluorite concentrate ngokwahlukana kwe-magnetic enamandla, ukuze kuphuculwe umgangatho we-concentrate.

Indandatho epholisiweyo edibeneyo yamanzi e-oyile kunye ne-vertical gradient separator ephezulu yemagnethi

Ukulungiswa kwe-hydrofluoric acid

I-Hydrofluoric acid yimveliso ephambili yekhemikhali. I-Hydrofluoric acid ifunyanwa ngokubolisa i-fluorite nge-sulfuric acid, indlela ebizwa ngokuba yi-sulfuric acid. Irhabaxa kakhulu kwaye ineendlela ezahlukeneyo zokusetyenziswa. Ihlala isetyenziselwa ukususa isanti kwi-metal castings, ukususa uthuthu lwe-graphite, ukucoca isinyithi, ukuvelisa i-semiconductor, ukucubungula i-ceramic, iglasi yokutshiza, ii-petroleum catalysts, njl.njl.

Uvavanyo lokususa i-ore ye-fluorite

Umxholo weCaF2 we-fluorite rough concentrate efunyenwe ngokutyibilika kwe-rare earth tailing eBayan Obo yi-86.17% kuphela, nto leyo eyahlukileyo kakhulu kwiimfuno zeemveliso ze-concentrate ezifanelekileyo. Ukongeza kwi-fluorite, i-rough concentrate ikwaqulathe i-rare earth kunye ne-hematite. , i-limonite, i-calcite, i-apatite, i-sodium pyroxene, i-amphibole, i-biotite kunye nezinye iiminerali. Iziqokeleli zesepha ze-fatty acid ezisetyenziswa kwi-fluorite flotation zinefuthe elithile lokuqokelela kwiiminerali ezine-iron. Phakathi kwezi minerali zokungcola, i-hematite, i-limonite, i-sodium pyroxene, i-amphibole, kunye ne-biotite zonke zinamandla kakhulu emagnethi, kwaye zinokususwa ngokwahlukana okunamandla kwemagnethi ukuphucula umgangatho we-fluorite concentrate.

I-200 mesh fluorite coarse concentrate enobuncinci be-93.50% yavavanywa ngokuthelekisa ukususwa kokungcola kunye nokucocwa ngeenkqubo ezimbini zokwahlulwa kwemagnethi ezinamandla aphezulu, ezifana ne-vertical ring + electromagnetic slurry high gradient magnetic separator kunye ne-vertical ring + superconducting magnetic separator.

Kuvavanyo lokuthelekisa ukususwa kokungcola okunamandla kwemagnethi, kwafunyaniswa ukuba ezinye iiminerali ezifana ne-hematite, i-limonite kunye ne-biotite ezinobuthathaka obuphezulu bemagnethi zinokususwa ngempumelelo ngokwahlukana okunamandla kwendandatho ethe nkqo, kwaye inqanaba le-CaF2 le-fluorite concentrate lonyuswe ukusuka kwi-86.17%. Emva koko iiminerali ezithwele isinyithi ezineempawu zemagnethi ezibuthathaka zisuswa nge-electromagnetic slurry kunye ne-superconducting magnetic separator, kwaye inqanaba le-CaF2 le-fluorite concentrate lonyuswe ukuya kwi-93.84% kunye ne-95.63% ngokulandelelana, zombini zifikelela kumgangatho womgangatho we-FC-93 kunye ne-FC-95. Isiphumo sokuzuza kwendandatho ethe nkqo kunye ne-electromagnetic slurry high gradient magnetic separator kunye ne-low temperature superconducting magnetic separator sicacile ngakumbi, esinokubonelela ngesiseko sobugcisa esithembekileyo sokususwa kokungcola okunamandla kwemagnethi kunye nokucocwa kwezi ziminerali.
