01shwankathela
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 kudla ngokubonakaliswa nguOkanyexAbyAnz(x+y+z=100), apho u-Or, Ab kunye no-An bamele amacandelo amathathu e-potassium feldspar, 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 ukuyityumza. edla ngokusetyenziswa njengoguquko kushishino lweceramic kunye neglasi;Isalathiso esisezantsi serefraction kunye ne-birefraction.Inokukhanya kweglasi, kodwa kaninzi inombala owahlukileyo kuba iqulethe ukungcola.Ininzi yezimbiwa zefeldspar zisetyenziswa njengezinto ezikrwada zeglasi 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.
Phantsi 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.Uhlobo lwesithathu yi-carbon organic efakwe kunye i-feldspar, enika i-ore umbala omnyama-omnyama.Kwiimeko ezininzi, i-carbon ye-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 ubukhulu becala bunezi ndlela zilandelayo: 1. Ikakhulu yi-monomer okanye i-aggregate ye-hematite, i-magnetite kunye ne-limonite enobukhulu besuntswana>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 ye-iron-bearing gangue minerals, njenge-biotite, i-limonite, i-pyrite, i-ferrotitanium ore, i-amphibole, i-epidote njalo njalo.
03 Iindlela ezixhaphakileyo zokuxhamla kwi-feldspar ore
Okwangoku, inkqubo ephambili yokuhamba kwe-feldspar ore yasekhaya ihlanjululwa ngokuqhelekileyo "ukutyumza - ukuhlelwa kokugaya - ukuhlukana kwamagnetic - 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 zesayizi encinci kunye nesantya esicothayo sokuzinzisa udongwe, udaka oluhle kunye ne-mica.Izixhobo ezisetyenziswa ngokuqhelekileyo zokuhlamba intsimbi ngumatshini wokukhuhla, isikrini esingcangcazelayo kunye netanki yokuhlamba intsimbi.
Injongo ephambili yokususwa kodaka kukususa i-ore yendabuko kwi-ore kunye ne-second ore yeklasi ephakathi yenkqubo yokugaya ephukile, kunye nokuthintela umphumo wokukhethwa okulandelayo kwe powder. Isixhobo se-deputer esiqhele ukusetyenziswa sine-hydraulic cyclone, classifier, centrifuge kunye ne-depuff.
(3) ukwahlukana ngokwemagnethi
Ukusebenzisa umahluko wemagnethi phakathi kwee-ores ezahlukeneyo, inkqubo yokususwa kwentsimbi phantsi kwesenzo semagnethi yangaphandle ibizwa ngokuba kukwahlulwa kwamagnetic.I-Feldspar 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 enozibuthe, uludaka lombane oluludaka oluphezulu lomahluli wemagnethi kunye ne-superconducting ephakame kakhulu isahlukanisi kazibuthe.
(4) ukudada
Flotation indlela ibhekiselele ukongezwa arhente uhlengahlengiso, umqokeleli, arhente amagwebu kunye nezinye ii-arhente kwi pulp yokusila izinto ekrwada, ukuze ubumdaka intsimbi encanyathiselwe kwiqamza, ukuze yona kunye nesisombululo pulp, kwaye ke oomatshini ukukhuhla ngaphandle, ukuze ukungcola kwentsimbi kunye nezinto eziluhlaza ukuhlukana komgubo ococekileyo.I-Flotation yindlela esebenzayo yokususa ukungcola kwe-feldspar. Ngakolunye uhlangothi, inokususa ukungcola okufana nentsimbi kunye ne-mica, kwaye ngakolunye uhlangothi, inokunyusa umxholo we-potassium kunye ne-sodium.Xa iminerali ihluke, ukhetho lwe-agent yokubamba luhluke, kodwa inkqubo ye-flotation ejikelezayo. inokwamkelwa.
