I-Feldspar yenye yezona zimbiwa eziqhelekileyo kwi-continental crust.Amacandelo ayo aphambili aquka iSiO2, Al2O3, K2Kwi2O njalo njalo.Iqukethe i-potassium, i-sodium, i-calcium kunye nenani elincinci le-barium kunye nezinye isinyithi ze-alkali okanye i-alkaline yomhlaba.Njengobuchule bemithombo yezimbiwa ezingezizo ezentsimbi, iiminerali ze-feldspar zisasazwe ngokubanzi kuqweqwe lomhlaba, kwaye zezona zimbiwa ze-silicate ezenziwe ngamatye asasazwa kakhulu ngaphandle kwequartz.Malunga ne-60% yazo ivela kumatye e-magmatic, i-30% kumatye e-metamorphic, kunye ne-10% kumatye e-sedimentary, kunye nobunzima obuyi-50% yobunzima bubonke bomhlaba. Kukho i-isomorphism ephuhliswe kakuhle kwi-feldspar minerals, kunye nekhemikhali. ukwakheka kuvame ukubonakaliswa nguOkanyexAbyAnz(x+y+z=100), apho u-Or, u-Ab kunye no-An bamele amacandelo amathathu e-potassium feldspar, i-albinite kunye ne-calcium feldspar, ngokulandelanayo.
Indawo yokunyibilika ye-feldspar ngokuqhelekileyo imalunga ne-1300 ℃, ukuxinana malunga ne-2.58g/cm.3, Ubulukhuni be-Mos 6.5, ubunzima obuthile buguquguquka phakathi kwe-2.5-3, i-brittle, i-compress resistance, i-grindability efanelekileyo kunye nokusebenza kophuhliso, kulula ukutyumza.Uzinzo oluhle lweekhemikhali, ukuxhathisa ukubola, ngaphandle koxinzelelo oluphezulu lwe-sulfuric acid kunye ne-hydrofluoric acid; Inceda umsebenzi wokunyibilika, ngokuqhelekileyo isetyenziswa njengemfucuza kwi-ceramic kunye ne-glass industry;Isalathisi esisezantsi se-refraction kunye ne-birefraction.Inokukhanya kweglasi, kodwa isoloko inombala owahlukileyo kuba iqulethe ukungcola.Ininzi yeeminerali ze-feldspar zisetyenziswa njengezinto eziluhlaza kwi-glass kunye ne-ceramic industry, kwaye ingasetyenziselwa unyango lwesichumiso, iziqholo kunye nezixhobo, ifayibha yeglasi kunye namanye amashishini.
02 Izinto ezichaphazela umgangatho we-feldspar
Eyokuqala yinto enekhono lokudaya, njengeFe, Ti, V, Cr, Mn, Cu, njl.
Ngaphantsi kweemeko eziqhelekileyo, i-Fe kunye ne-Ti zezona zinto ziphambili zokudaya, ezinye izinto eziqulethwe zincinci kakhulu, idigri emhlophe inefuthe elincinci.
Udidi lwesibini luneeminerali ezimnyama, ezifana ne-biotite, i-rutile, i-chlorite kunye nokunye.Umxholo weeminerali ezimnyama kwi-mineral rocks uphantsi, kodwa unempembelelo enkulu kumgangatho we-feldspar concentrate.Udidi lwesithathu yi-carbon organic efakwe kunye I-feldspar, enika i-ore i-ore-black color.Kwiimeko ezininzi, i-carbon organic kulula ukususwa kwiqondo lokushisa eliphezulu, kwaye ubumhlophe bunempembelelo encinci.Izinto eziphambili zeemveliso zoshishino ziyintsimbi, i-titanium kunye nentsimbi, kunye nomphezulu wemveliso uya kubonakala amabala amnyama, umxholo we-calcium uphezulu kakhulu, umgangatho wemveliso awulingani, ngoko ke ukuphucula umgangatho wamaminerali amatye amade, ukusetyenziswa kwelitye elide, umxholo wamaminerali amnyama kunye i-calcium kufuneka icuthwe, ngakumbi ukususwa kwe-iron oxide.
Ubukho be-iron kwi-feldspar ikakhulu inezi ntlobo zilandelayo: 1. Ikakhulu i-monomer okanye i-aggregate ye-hematite, i-magnetite kunye ne-limonite kunye nobukhulu be-particle ye->0.1mm.I-spherical, i-needle-like, i-flakelike okanye ingaqhelekanga, ihlakazeke kakhulu kwiiminerali ze-feldspar kwaye kulula ukuyisusa.Okwesibini, umphezulu we-feldspar ungcoliswe yi-iron oxide ngendlela ye-seapage, okanye ecaleni kweentanda, iiminerali kunye ne-cleavage joints of feldspar. ukuhanjiswa kokungena, i-oxide yesinyithi eyenziwe yidayi yentsimbi inyusa kakhulu ubunzima bokususwa kwesinyithi.Okwesithathu, ikhona ngendlela yesinyithi esinezimbiwa ze-ganggue, ezifana ne-biotite, i-limonite, i-pyrite, i-ferrotitanium ore, i-amphibole, i-epidote njalo njalo.
03 Iindlela ezixhaphakileyo zoncedo lwefeldspar ore
Okwangoku, inkqubo ephambili yokuhamba kwe-feldspar ore yasekhaya yokuhlanjululwa ngokuqhelekileyo "ukutyumza - ukuhlelwa kokugaya - ukuhlukana kwamagnetic - i-flotation", ngokwemixholo eyahlukeneyo yokungcola kwamaminerali e-feldspar kunye neempawu ze-ganggue mineral embedded, kunye nokuhlukana kwezandla, ukuchithwa, ukuhlelwa kunye neminye imisebenzi.
(1) ukutyumza kunye nokusila
Ukutyunyuzwa kwe-feldspar kwahlulwe kukutyumza okurhabaxa kunye nokutyunyuzwa kakuhle.Uninzi lweentsimbi ezikrwada kufuneka zidlule kwiinkqubo ezimbini zokutyunyuzwa okurhabaxa kunye nokucolwa kakuhle.Ukutyumza okuninzi kwesityuli somhlathi, izixhobo zokutyumza ubukhulu becala uhlobo lwesityuli, isityuli sohlobo lwehamile, isityuli sohlobo lwempembelelo, njl.
Ukusila kwe-feldspar kwahlulahlulwe ikakhulu kukusila okomileyo kunye nokusila okumanzi.
Ukusebenza kakuhle kokugaya okumanzi kuphezulu kunokugaya okomileyo, kwaye i-phenomenon ye "over-grinding" ayilula ukubonakala.Izixhobo zokugaya ziyi-ball mill, i-rod mill, i-tower mill, i-sanding mill, i-vibration mill, i-airflow mill, njl.
(2) Ukuhlamba kunye nokudiliza
I-Feldspar ore kwinkqubo yokwakheka ngaphezulu okanye ngaphantsi iya kuqulatha inani elithile le-slime.Ukuhlamba ikakhulu ukususa ukungcola okufana nodongwe, udaka oluhle kunye ne-mica kwi-feldspar.Ukuhlamba kunokunciphisa umxholo we-Fe.2O3kwintsimbi ekrwada, kunye nokuphucula umxholo we-K2O kunye noNa2Ukuhlamba i-O.Ore kukwahlula kwiiminerali ezinqabileyo phantsi kwesenzo sokuhamba kwamanzi ngokuthatha inzuzo yeempawu zobungakanani bencinci encinci kunye nesantya esicothayo sokumisa udongwe, udaka oluhle kunye ne-mica.Isixhobo sokuhlamba i-ore esisetyenziswa ngokuqhelekileyo ngumatshini wokukhuhla, isikrini esingcangcazelayo kunye netanki yokuhlamba intsimbi.
Injongo ephambili yokususwa kodaka kukususa i-ore yendalo kwi-ore kunye ne-second ore yeklasi ephakathi yenkqubo yokugaya ephukileyo, kunye nokuthintela umphumo wokukhethwa okulandelayo kwe powder.Isixhobo sedeputer esiqhele ukusetyenziswa sine-hydraulic cyclone, classifier, centrifuge and depuff.
(3) ukwahlukana ngokwemagnethi
Ukusebenzisa umahluko wemagnethi phakathi kwee-ore ezahlukeneyo, inkqubo yokususa intsimbi phantsi kwesenzo semagnethi yangaphandle ibizwa ngokuba yimagnethi separation.IFeldspar ayinayo umazibuthe, kodwa iFeldspar2O3kunye ne-mica e-feldspar ine-magnetism ebuthathaka, ngoko ke phantsi kwemeko yokomeleza intsimi yangaphandle, i-Fe2O3, i-mica kunye ne-feldspar inokwahlulwa. umahluli kazibuthe, ipleyiti yemagnethi emanzi isahluli kazibuthe, iringi ethe nkqo kwisahluli semagnethi enobunzima obuphezulu, udaka lwe-electromagnetic ludaka umahluli ophakamileyo wemagnethi kunye ne-superconducting ephakame kakhulu isahluli semagnethi.
(4) ukudada
Flotation indlela libhekisela ukongeza arhente uhlengahlengiso, umqokeleli, arhente amagwebu kunye nezinye ii-arhente kwi pulp yokusila ekrwada, ukuze ubumdaka intsimbi encanyathiselwe kwiqamza, ukuze yona kunye nesisombululo pulp, kwaye ke mechanical ukukhuhla ngaphandle, ukuze ukungcola kwentsimbi kunye nezinto eziluhlaza ukuhlukana komgubo ococekileyo.I-Flotation yindlela esebenzayo yokususa ukungcola kwe-feldspar.Ngakolunye uhlangothi, kunokususa ukungcola okufana nentsimbi kunye ne-mica, kwaye ngakolunye uhlangothi, kunokunyusa umxholo we-potassium kunye ne-sodium.Xa iminerali ihluke, ukhetho lwe-agent yokubamba luhluke, kodwa inkqubo yokujikeleza ejikelezayo. inokwamkelwa.
