01 shwankathela
I-Feldspar yenye yezona zimbiwa zixhaphakileyo kuqweqwe lwelizwekazi. Izinto eziphambili zayo ziquka i-SiO22, Al2O3, K2Kwi2O njalo njalo. Iqulethe i-potassium, i-sodium, i-calcium kunye nenani elincinci le-barium kunye nezinye ii-alkali metals okanye ii-alkaline earth metals. Njengezixhobo zezimbiwa ezingezizo ezesinyithi, ii-feldspar minerals zisasazeke kakhulu kuqweqwe lomhlaba, kwaye zezona zimbiwa zenza ilitye le-silicate ezisasazeke kakhulu ngaphandle kwe-quartz. Malunga ne-60% yazo zivela kumatye e-magmatic, i-30% kumatye e-metamorphic, kunye ne-10% kumatye e-sedimentary, enobunzima obupheleleyo be-50% yobunzima obupheleleyo bomhlaba. Kukho i-isomorphism ephuhliswe kakuhle kwiiminerali ze-feldspar, kwaye ukwakheka kweekhemikhali kudla ngokubonakaliswa yi-OrxAbyAnz(x+y+z=100), apho u-Or, u-Ab kunye no-An bamele izinto ezintathu ze-potassium feldspar, i-albinite kunye ne-calcium feldspar, ngokwahlukeneyo.
Iqondo lokunyibilika kwe-feldspar ngokubanzi limalunga ne-1300℃, uxinano lumalunga ne-2.58g/cm3, Ubunzima beMos 6.5, ubunzima obuthile buyatshintshatshintsha phakathi kwe-2.5-3, bubuthathaka, buxhathisa ucinezelo, buyakwazi ukugaywa kakuhle kunye nokusebenza kakuhle kophuhliso, kulula ukutyumza. Uzinzo oluhle lweekhemikhali, luxhathisa ukugqwala, ngaphandle koxinzelelo oluphezulu lwe-sulfuric acid kunye ne-hydrofluoric acid; Inceda umsebenzi wokunyibilikisa, osetyenziswa rhoqo njenge-flux kushishino lwe-ceramic kunye neglasi; Isalathisi esiphantsi sokurhawuzelelwa kunye nokuqhekeka kwe-birefraction. Inokukhanya okufana neglasi, kodwa idla ngokuba nombala owahlukileyo kuba iqulethe ukungcola. Uninzi lweeminerali ze-feldspar zisetyenziswa njengezinto eziluhlaza kwishishini leglasi kunye ne-ceramic, kwaye zingasetyenziselwa unyango lwesichumiso, izinto eziqhekezayo kunye nezixhobo, i-fiber yeglasi kunye neminye imboni.
02 Izinto ezichaphazela umgangatho we-feldspar
Eyokuqala sisiqalelo esikwaziyo ukudaya, esifana neFe, Ti, V, Cr, Mn, Cu, njl.
Kwiimeko eziqhelekileyo, iFe kunye neTi zezona zinto ziphambili zokudaya, ezinye izinto zincinci kakhulu, inqanaba elimhlophe alinampembelelo ingako.
Udidi lwesibini ziiminerali ezimnyama, ezifana ne-biotite, i-rutile, i-chlorite njalo njalo. Umxholo weeminerali ezimnyama ematyeni eeminerali uphantsi, kodwa unempembelelo enkulu kumgangatho we-feldspar concentrate. Uhlobo lwesithathu yi-organic carbon efakwe kwi-feldspar, enika i-ore umbala ongwevu-mnyama. Kwiimeko ezininzi, i-organic carbon kulula ukuyisusa kubushushu obuphezulu, kwaye ubumhlophe abunampembelelo ingako. Izinto eziphambili kwiimveliso zoshishino yi-iron, titanium, kunye ne-iron, kwaye umphezulu wemveliso uya kubonakala amabala amnyama, umxholo we-calcium uphezulu kakhulu, umphezulu wemveliso awulingani, ngoko ke ukuphucula umgangatho weeminerali zelitye elide, ukusetyenziswa kwelitye elide, umxholo weeminerali ezimnyama kunye ne-calcium kufuneka kuncitshiswe, ingakumbi ukususwa kwe-iron oxide.
Ubukho bentsimbi kwi-feldspar bunezi ntlobo zilandelayo: 1. Ngokuyintloko yi-monomer okanye i-aggregate ye-hematite, i-magnetite kunye ne-limonite enobukhulu be-particle obuyi->0.1mm. Ingqukuva, ifana nenaliti, ifana ne-flake okanye ayiqhelekanga, isasazeke kakhulu kwiiminerali ze-feldspar kwaye kulula ukuyisusa. Okwesibini, umphezulu we-feldspar ungcoliswa yi-iron oxide ngendlela yokuvuza, okanye ecaleni kwemifantu, iiminerali kunye namalungu okuqhekeka kokusasazwa kokungena kwe-feldspar, i-iron oxide eyenziwe yidayi yentsimbi inyusa kakhulu ubunzima bokususwa kwentsimbi. Okwesithathu, ikhona ngohlobo lweeminerali ze-gangue ezine-iron, ezifana ne-biotite, i-limonite, i-pyrite, i-ferrotitanium ore, i-amphibole, i-epidote njalo njalo.
03 Iindlela ezisetyenziswa rhoqo zokuphucula i-feldspar ore
Okwangoku, inkqubo ephambili yokucocwa kwe-feldspar ore yasekhaya ngokubanzi "kukutyumza - ukwahlulahlula ngokugaya - ukwahlulwahlulwa ngemagnethi - ukutyibilika", ngokwemixholo eyahlukeneyo yokungcola kweeminerali ze-feldspar kunye neempawu ze-gangue mineral ezifakwe ngaphakathi, kunye nokwahlulwa ngesandla, ukususwa, ukwahlulwahlulwa kunye neminye imisebenzi.
(1) ukutyumza nokusila
Ukutyunyuzwa kwe-feldspar kwahlulwe ngokutyunyuzwa okucolekileyo nokutyunyuzwa okucolekileyo. Uninzi lweentsimbi kufuneka zidlule kwiinkqubo ezimbini zokutyunyuzwa okucolekileyo nokutyunyuzwa okucolekileyo. Ukutyunyuzwa okucolekileyo uninzi lwe-jaw crusher, izixhobo zokutyunyuzwa ikakhulu yi-impact type crusher, i-hammer type crusher, i-impact type crusher, njl.njl.
Ukusila kwe-feldspar kwahlulwe ngokubanzi kwi-dry grinding kunye ne-wet grinding.
Ukusebenza kakuhle kokugaya okumanzi kuphezulu kunokokugaya okomileyo, kwaye isiganeko "sokugaya kakhulu" asilula ukuvela. Izixhobo zokugaya ikakhulu ziibhola, i-rod mill, i-tower mill, i-sanding mill, i-vibration mill, i-airflow mill, njl.njl.
(2) Ukuhlamba kunye nokususa uthuli emzimbeni
I-ore ye-feldspar kwinkqubo yokwakheka inokuba ne-slime ethile. Ukuhlamba ikakhulu kukususa ukungcola okufana nodongwe, udaka olucolekileyo kunye ne-mica kwi-feldspar. Ukuhlamba kunokunciphisa umxholo we-Fe2O3kwi-ore, kwaye iphucula umxholo we-K2U-O kunye no-Na2Ukuhlamba i-ore kukwahlula kwiiminerali ezirhabaxa phantsi kwentshukumo yokuhamba kwamanzi ngokusebenzisa iimpawu zobukhulu obuncinci beesuntswana kunye nesantya sokuzinza kancinci kodongwe, udaka olucolekileyo kunye ne-mica. Izixhobo zokuhlamba i-ore ezisetyenziswa kakhulu ngumatshini wokukrwela, isikrini sokungcangcazela kunye netanki yokuhlamba i-ore.
Eyona njongo iphambili yokususa udaka kukususa i-ore yendalo kwi-ore nakwi-ore yesibini yodidi oluphakathi lwenkqubo yokusila ephukileyo, kunye nokuthintela isiphumo sokukhethwa okulandelayo komgubo. Izixhobo ze-deputer ezisetyenziswa rhoqo zine-hydraulic cyclone, i-classifier, i-centrifuge kunye ne-depuff.
(3) ukwahlukana kwemagnethi
Ngokusebenzisa umahluko wemagnethi phakathi kwee-ore ezahlukeneyo, inkqubo yokususwa kwesinyithi phantsi kwesenzo sentsimi yemagnethi yangaphandle ibizwa ngokuba kukwahlulwa kwemagnethi. IFeldspar ayinamagnethi, kodwa iFe2O3kwaye i-mica kwi-feldspar inemagnetism ebuthathaka, ngoko ke phantsi kwemeko yokuqinisa intsimi yemagnethi yangaphandle, i-Fe2O3, i-mica kunye ne-feldspar zinokuhlulwahlulwa. Okwangoku, izixhobo zokwahlulahlula imagnethi ezisetyenziswa rhoqo eTshayina ziquka ikakhulu i-rare earth roller magnetic separator, i-permanent magnet drum magnetic separator, i-wet magnetic plate separator, i-vertical ring high gradient magnetic separator, i-electromagnetic slurry high gradient magnetic separator kunye ne-superconducting high intensity magnetic separator.
(4) ukudada
Indlela yokuqubha ibhekisa ekongezweni kwearhente yokulungisa, umqokeleli, iarhente yokufutha kunye nezinye iiarhente kwipulp yezinto eziluhlaza zokugaya, ukuze ukungcola kwesinyithi kunamathele kwiqamza, ukuze yona kunye nesisombululo sepulp, kwaye emva koko kukhuhlwe ngoomatshini, ukuze ukungcola kwesinyithi kunye nokwahlulwa komgubo ocolekileyo wezinto eziluhlaza. Ukuqubha yindlela esebenzayo yokususa ukungcola kwefeldspar. Kwelinye icala, inokususa ukungcola okufana nentsimbi kunye ne-mica, kwaye kwelinye icala, inokunyusa umxholo we-potassium kunye ne-sodium. Xa iminerali yahlukile, ukhetho lwearhente yokubamba lwahlukile, kodwa inkqubo yokuqubha engasemva inokusetyenziswa.
