I-Feldspar ingenye yamaminerali avame kakhulu ku-continental crust. Izingxenye zayo eziyinhloko zihlanganisa i-SiO2, Al2O3, K2O, Na2O nokunye. Iqukethe i-potassium, i-sodium, i-calcium kanye nenani elincane le-barium nezinye izinsimbi ze-alkali noma izinsimbi zomhlaba ezine-alkaline. Njengemithombo yamaminerali engeyona eyensimbi enamasu, amaminerali e-feldspar asabalaliswa kabanzi oqweqweni lomhlaba, futhi angamaminerali akha amatshe e-silicate asatshalaliswa kakhulu ngaphandle kwequartz. Cishe amaphesenti angu-60 awo avela emadwaleni amakhulu, ama-30% emadwaleni e-metamorphic, kanye ne-10% emadwaleni e-sedimentary, anesisindo esiphelele sama-50% wesisindo somhlaba wonke.Kukhona isomorphism ethuthuke kahle kumaminerali e-feldspar, kanye namakhemikhali. ukwakheka kuvame ukuvezwa ngu-OrxAbyAnz(x+y+z=100), lapho u-Or, Ab kanye no-An bamelela izingxenye ezintathu ze-potassium feldspar, albinite ne-calcium feldspar, ngokulandelana.
Indawo encibilikayo ye-feldspar ivamise ukuba ngu-1300 ℃, ukuminyana kucishe kube ngu-2.58g/cm.3, Ubulukhuni be-Mos 6.5, amandla adonsela phansi athile ashintshashintsha phakathi kuka-2.5-3, brittle, ukumelana nokucindezelwa, ukugaya okuhle nokusebenza kwentuthuko, kulula ukuchotshozwa.Ukuzinza okuhle kwamakhemikhali, ukumelana nokugqwala, ngaphandle kokugcwala okuphezulu kwe-sulfuric acid ne-hydrofluoric acid;Isiza ukuncibilika komsebenzi, evame ukusetshenziswa njenge-flux embonini ye-ceramic kanye nengilazi;Inkomba ephansi ye-refraction kanye ne-birefraction.Inokucwebezela okuyingilazi, kodwa ngokuvamile inombala ohlukile ngoba iqukethe ukungcola.Iningi lamaminerali e-feldspar asetshenziswa njengezinto ezingavuthiwe zemboni yengilazi kanye ne-ceramic, futhi ingasetshenziswa futhi ekwelapheni umanyolo, ama-abrasives namathuluzi, i-glass fiber nezinye izimboni.
02 Izinto ezithinta ikhwalithi ye-feldspar
Esokuqala yisici esinekhono lokudaya, njengeFe, Ti, V, Cr, Mn, Cu, njll.
Ngaphansi kwezimo ezijwayelekile, i-Fe ne-Ti yizici eziyinhloko zokudaya, ezinye izakhi okuqukethwe kuncane kakhulu, idigri emhlophe ayinathonya elincane.
Isigaba sesibili ngamaminerali amnyama, afana ne-biotite, i-rutile, i-chlorite nokunye.Okuqukethwe kwamaminerali amnyama emadwaleni amaminerali kuphansi, kodwa kunethonya elikhulu kukhwalithi ye-feldspar concentrate.Uhlobo lwesithathu yi-organic carbon deposited with i-feldspar, enikeza insimbi umbala ompunga-omnyama.Ezimweni eziningi, ikhabhoni ephilayo kulula ukususwa lapho izinga lokushisa liphezulu, futhi ubumhlophe bunomphumela omncane.Izici eziyinhloko zemikhiqizo yemboni insimbi, i-titanium, nensimbi, futhi ubuso bomkhiqizo buzovela amabala amnyama, okuqukethwe kwe-calcium kuphezulu kakhulu, ingaphezulu lomkhiqizo alilingani, ngakho-ke ukuthuthukisa ikhwalithi yamaminerali amatshe amade, ukusetshenziswa kwetshe elide, okuqukethwe kwamaminerali amnyama kanye i-calcium kufanele incishiswe, ikakhulukazi ukususwa kwe-iron oxide.
Ukuba khona kwensimbi ku-feldspar ikakhulukazi kunalezi zinhlobo ezilandelayo: 1. Ngokuyinhloko i-monomer noma i-aggregate ye-hematite, i-magnetite ne-limonite enosayizi wezinhlayiyana >0.1mm. I-spherical, efana nenaliti, efana ne-flake noma engavamile, ihlakazeke kakhulu kumaminerali e-feldspar futhi kulula ukuyisusa.Okwesibili, ingaphezulu le-feldspar lingcoliswa i-iron oxide ngendlela yokuphuma kwamanzi, noma eduze kwemifantu, amaminerali kanye namalunga okuqhekeka kwe-feldspar. ukusatshalaliswa kokungena, i-iron oxide eyakhiwe udayi wensimbi yandisa kakhulu ubunzima bokukhishwa kwensimbi.Okwesithathu, ikhona ngendlela yamaminerali e-ganggue enensimbi, njenge-biotite, i-limonite, i-pyrite, i-ferrotitanium ore, i-amphibole, i-epidote nokunye.
03 Izindlela zokuhlomula ezisetshenziswa kakhulu ze-feldspar ore
Njengamanje, ukugeleza kwenqubo eyinhloko yokuhlanzwa kwe-feldspar ore yasekhaya ngokuvamile "ukuchoboza - ukuhlukaniswa kokugaya - ukuhlukaniswa kwamagnetic - flotation", ngokusho kokuqukethwe okungcolile kwe-feldspar amaminerali kanye nezici ezifakwe kumaminerali e-ganggue, nokuhlukaniswa kwezandla, ukuchithwa, ukuhlukaniswa neminye imisebenzi.
(1) ukuchoboza nokugaya
Ukuchotshozwa kwe-feldspar kuhlukaniswe ukuchotshozwa okuqinile nokuchotshozwa kahle. Insimbi eningi kufanele idlule ezinqubweni ezimbili zokuchotshozwa okumahhadla nokuchotshozwa kahle.Ukuchoboza okuqinile okuningi kwesigxobo somhlathi, okokusebenza kokuchotshozwa okuyinhloko okuthinta uhlobo lwe-crusher, i-crusher yohlobo lwesando, i-crusher yohlobo lomthelela, njll.
Ukugaya kwe-feldspar kuhlukaniswe ikakhulukazi ukugaya okomile nokugaya okumanzi.
Ukusebenza kahle kokugaya okumanzi kuphakeme kunokugaya okomile, futhi isenzakalo "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
I-Feldspar ore ngesikhathi sokwakheka izoqukatha inani elithile le-slime.Ukugeza ikakhulukazi ukususa ukungcola okunjengobumba, udaka oluhle kanye ne-mica e-feldspar.Ukugeza kunganciphisa okuqukethwe kwe-Fe.2O3ku-ore, futhi futhi uthuthukise okuqukethwe kwe-K2O kanye Na2Ukugeza i-O.Ore kuwukwehlukanisa namaminerali anezinhlamvu ezimahhadla ngaphansi kokugeleza kwamanzi ngokusebenzisa izici zobukhulu bezinhlayiyana ezincane kanye nesivinini sokumisa kancane sobumba, udaka oluhle kanye ne-mica.Imishini yokuwasha insimbi evame ukusetshenziswa umshini wokukhuhla, isikrini esidlidlizayo kanye nethangi lokuwasha lensimbi.
Inhloso eyinhloko yokukhishwa kodaka ukukhipha insimbi yomdabu e-ore kanye ne-ore yesibili yesigaba esiphakathi senqubo yokugaya ephukile, nokuvimbela umphumela wokukhethwa okulandelayo kwempushana. Izinto ezisetshenziswa kakhulu zedeputer zine-hydraulic cyclone, classifier, centrifuge kanye ne-depuff.
(3) ukuhlukaniswa kazibuthe
Ngokusebenzisa umehluko kazibuthe phakathi kwama-ore ahlukahlukene, inqubo yokukhishwa kwensimbi ngaphansi kwesenzo sensimu kazibuthe yangaphandle ibizwa ngokuthi ukuhlukaniswa kazibuthe.I-Feldspar ayinawo uzibuthe, kodwa i-Fe.2O3futhi i-mica e-feldspar inozibuthe obuthakathaka, ngakho-ke ngaphansi kwesimo sokuqinisa insimu yamagnetic yangaphandle, i-Fe2O3, i-mica ne-feldspar ingahlukaniswa.Okwamanje, imishini yokuhlukanisa kazibuthe evame ukusetshenziswa e-China ikakhulukazi ihlanganisa isihlukanisi esingavamile somhlaba esihlukanisa i-magnetic, isigubhu samagnetic unomphela. isihlukanisi kazibuthe, isihlukanisi sikazibuthe esimanzi esimanzi, isihlukanisi kazibuthe esimanzi, indandatho eqondile yesihlukanisi enozibuthe ene-gradient ephezulu, i-electromagnetic slurry high gradient separator kazibuthe kanye ne-superconducting high intensity high separator.
(4) ukuntanta
Indlela ye-Flotation ibhekisela ekwengezeni i-ejenti yokulungisa, umqoqi, i-ejenti egwebuzelayo kanye namanye ama-agent ku-pulp yokugaya impahla eluhlaza, ukuze ukungcola kwensimbi okunamathiselwe ku-bubble, ukuze yona kanye nesisombululo se-pulp, bese ikhishwa ngomshini, ukuze ukungcola kwensimbi kanye nempahla eluhlaza ukuhlukaniswa kwe-powder emihle.I-Flotation iyindlela ephumelelayo yokususa ukungcola kwe-feldspar. Ngakolunye uhlangothi, ingakwazi ukususa ukungcola okufana nensimbi ne-mica, futhi ngakolunye uhlangothi, ingandisa okuqukethwe kwe-potassium ne-sodium.Lapho i-mineral ihlukile, ukukhethwa kwe-ejenti yokubamba kuhlukile, kodwa inqubo ye-flotation ingamukelwa.
