I-Feldspar ingenye yamaminerali avame kakhulu oqweqweni lwezwekazi. Izingxenye zayo eziyinhloko zifaka i-SiO22, Al2O3, K2O, Na2O njalo njalo. Iqukethe i-potassium, i-sodium, i-calcium kanye nenani elincane le-barium nezinye izinsimbi ze-alkali noma izinsimbi zomhlaba ze-alkaline. Njengemithombo yamaminerali engeyona eyensimbi eyisisekelo, amaminerali e-feldspar asatshalaliswa kabanzi oqweqweni lomhlaba, futhi angamaminerali akha idwala le-silicate asatshalaliswa kakhulu ngaphandle kwe-quartz. Cishe ama-60% awo atholakala emadwaleni e-magmatic, ama-30% emadwaleni e-metamorphic, kanye nama-10% emadwaleni e-sedimentary, enesisindo esiphelele sama-50% sesisindo esiphelele somhlaba. Kukhona i-isomorphism ethuthukisiwe kahle kumaminerali e-feldspar, futhi ukwakheka kwamakhemikhali kuvame ukuvezwa yi-OrxAbyAnz(x+y+z=100), lapho u-Or, u-Ab no-An bemelela izingxenye ezintathu ze-potassium feldspar, i-albinite kanye ne-calcium feldspar, ngokulandelana.
Iphuzu lokuncibilika kwe-feldspar ngokuvamile licishe libe ngu-1300℃, ubuningi bungaba ngu-2.58g/cm3, Ukuqina kwe-Mos 6.5, amandla adonsela phansi athile ayashintshashintsha phakathi kuka-2.5-3, ayaphuka, ayamelana nokucindezelwa, ayagaywa kahle futhi asebenza kahle ekuthuthukisweni, kulula ukuwachoboza. Ukuqina okuhle kwamakhemikhali, ukumelana nokugqwala, ngaphandle kokuhlushwa okuphezulu kwe-sulfuric acid kanye ne-hydrofluoric acid; Kusiza ukusebenza kokuncibilikisa, okuvame ukusetshenziswa njengokushintshashintsha embonini ye-ceramic nengilazi; Inkomba ephansi yokumelana kanye nokuqhekeka kwe-birefraction. Inokukhanya okufana nengilazi, kodwa ivame ukuba nombala ohlukile ngoba iqukethe ukungcola. Iningi lamaminerali e-feldspar asetshenziswa njengezinto zokusetshenziswa zemboni yengilazi neye-ceramic, futhi angasetshenziswa futhi ekwelapheni umanyolo, izinto zokubhula namathuluzi, i-fiber yengilazi kanye neminye imboni.
02 Izici ezithinta ikhwalithi ye-feldspar
Esokuqala yisici esinekhono lokudaya, njenge-Fe, Ti, V, Cr, Mn, Cu, njll.
Ngaphansi kwezimo ezivamile, i-Fe ne-Ti yizona zinto eziyinhloko zokudaya, okuqukethwe kwezinye izinto kuncane kakhulu, izinga elimhlophe alinathonya elikhulu.
Isigaba sesibili amaminerali amnyama, njenge-biotite, i-rutile, i-chlorite njalo njalo. Okuqukethwe kwamaminerali amnyama emadwaleni amaminerali kuphansi, kodwa kunethonya elikhulu kwikhwalithi ye-feldspar concentrate. Uhlobo lwesithathu yi-organic carbon efakwe ku-feldspar, enikeza i-ore umbala ompunga-mnyama. Ezimweni eziningi, i-organic carbon kulula ukuyisusa ekushiseni okuphezulu, futhi ubumhlophe abunamthelela omkhulu. Izinto eziyinhloko zemikhiqizo yemboni yi-iron, i-titanium, ne-iron, kanti ubuso bomkhiqizo buzovela amabala amnyama, okuqukethwe kwe-calcium kuphakeme kakhulu, ubuso bomkhiqizo abulingani, ngakho-ke ukuze kuthuthukiswe ikhwalithi yamaminerali amade etshe, ukusetshenziswa kwetshe elide, okuqukethwe kwamaminerali amnyama ne-calcium kumele kuncishiswe, ikakhulukazi ukususwa kwe-iron oxide.
Ukuba khona kwensimbi ku-feldspar ikakhulukazi kunezinhlobo ezilandelayo: 1. Ngokuyinhloko iyi-monomer noma i-aggregate ye-hematite, i-magnetite kanye ne-limonite enobukhulu bezinhlayiya obungu->0.1mm. Iyindilinga, ifana nenaliti, ifana ne-flake noma ayijwayelekile, isakazeke kakhulu kumaminerali e-feldspar futhi kulula ukuyisusa. Okwesibili, ubuso be-feldspar bungcoliswa yi-iron oxide ngendlela yokuvuza, noma eduze kwemifantu, amaminerali kanye namajoyinti okuqhekeka kokusabalalisa kokungena kwe-feldspar, i-iron oxide eyakhiwe ngodayi wensimbi yandisa kakhulu ubunzima bokususwa kwensimbi. Okwesithathu, ikhona ngesimo samaminerali e-gangue aphethe insimbi, njenge-biotite, i-limonite, i-pyrite, i-ferrotitanium ore, i-amphibole, i-epidot njalo njalo.
03 Izindlela zokuzuza ezisetshenziswa kakhulu ze-feldspar ore
Njengamanje, ukugeleza kwenqubo eyinhloko yokuhlanzwa kwe-feldspar ore yasekhaya ngokuvamile "ukuchoboza - ukuhlukaniswa kokugaya - ukuhlukaniswa kwamagnetic - ukuntanta", ngokuya ngokuqukethwe okuhlukile kokungcola kwamaminerali e-feldspar kanye nezici ezifakiwe zamaminerali e-gangue, kanye nokuhlukaniswa kwesandla, ukukhipha, ukuhlukaniswa kanye neminye imisebenzi.
（1） ukuchoboza nokugaya
Ukuchotshozwa kwe-feldspar kuhlukaniswe ngokuchotshozwa okukhulu kanye nokuchotshozwa okuncane. Iningi lama-ore kufanele lidlule ezinqubweni ezimbili zokuchotshozwa okukhulu kanye nokuchotshozwa okuncane. Ukuchotshozwa okukhulu kakhulu kwe-jaw crusher, imishini yokuchotshozwa ikakhulukazi i-impact type crusher, i-hammer type crusher, i-impact type crusher, njll.
Ukugaya i-feldspar kuhlukaniswe kakhulu ngokugaya okomile kanye nokugaya okumanzi.
Ukusebenza kahle kokugaya okumanzi kuphakeme kunokugaya okomile, futhi isimo "sokugaya ngokweqile" akulula ukuvela. Imishini yokugaya ikakhulukazi i-ball mill, i-rod mill, i-tower mill, i-sanding mill, i-vibration mill, i-airflow mill, njll.
（2）Ukugeza nokususa ukungcola
I-ore ye-feldspar enkambisweni yokwakheka cishe izoqukatha inani elithile le-slime. Ukuhlanza ngokuyinhloko kuhloselwe ukususa ukungcola okufana nobumba, udaka olucolekile kanye ne-mica ku-feldspar. Ukuhlanza kunganciphisa okuqukethwe yi-Fe2O3ku-ore, futhi kuthuthukise okuqukethwe yi-K2U-O no-Na2Ukuhlanza i-O.Ore kuhlukaniswa namaminerali aqinile ngaphansi kwesenzo sokugeleza kwamanzi ngokusebenzisa izici zobukhulu bezinhlayiya ezincane kanye nesivinini sokuzinza kancane kobumba, udaka olucolekile kanye ne-mica. Imishini yokuwasha i-ore evame ukusetshenziswa umshini wokuhlafuna, isikrini esidlidlizayo kanye nethangi lokuwasha i-ore.
Inhloso eyinhloko yokususwa kodaka ukususa i-ore yemvelo ku-ore kanye ne-ore yesibili yesigaba esiphakathi senqubo yokugaya ephukile, nokuvimbela umphumela wokukhethwa okulandelayo kwempuphu. Imishini yokususa esetshenziswa kakhulu ine-hydraulic cyclone, i-classifier, i-centrifuge kanye ne-depuff.
(3) ukuhlukaniswa kwamagnetic
Ngokusebenzisa umehluko wamagnetic phakathi kwama-ore ahlukahlukene, inqubo yokususwa kwensimbi ngaphansi kwesenzo sensimu yamagnetic yangaphandle ibizwa ngokuthi ukuhlukaniswa kwamagnetic. I-Feldspar ayinamagnetism, kodwa i-Fe2O3kanye ne-mica ku-feldspar ine-magnetism ebuthakathaka, ngakho-ke ngaphansi kwesimo sokuqinisa insimu yamagnetic yangaphandle, i-Fe2O3, i-mica kanye ne-feldspar zingahlukaniswa. Njengamanje, imishini yokuhlukanisa amandla kazibuthe esetshenziswa kakhulu eShayina ifaka phakathi i-rare earth roller magnetic separator, i-permanent magnet drum magnetic separator, i-wet magnetic plate magnetic separator, i-vertical ring high gradient magnetic separator, i-electromagnetic slurry high gradient magnetic separator kanye ne-superconducting high intensity magnetic separator.
(4) ukuntanta
Indlela yokuntanta ibhekisela ekufakweni kwe-ejenti yokulungisa, umqoqi, i-ejenti ye-foam kanye nezinye izinto ezisetshenziswayo ku-pulp yezinto zokusetshenziswa ezigayiwe, ukuze ukungcola kwensimbi kunamathele ku-bubble, ukuze yona kanye nesixazululo se-pulp, bese kukhuhlwa ngomshini, ukuze ukungcola kwensimbi kanye nokuhlukaniswa kwempuphu ecolekileyo yezinto zokusetshenziswa. Ukuntanta kuyindlela ephumelelayo yokususa ukungcola kwe-feldspar. Ngakolunye uhlangothi, kungasusa ukungcola okufana ne-iron ne-mica, kanti ngakolunye uhlangothi, kungandisa okuqukethwe kwe-potassium ne-sodium. Uma i-mineral ihlukile, ukukhetha i-ejenti yokubamba kuhlukile, kodwa inqubo yokuntanta engemuva ingasetshenziswa.
