Feldspar ndeimwe yemaminerari anowanikwa zvakanyanya mugungwa. Zvikamu zvayo zvikuru zvinosanganisira SiO22, Al2O3, K2O, Kwete2O zvichingodaro. Ine potassium, sodium, calcium uye huwandu hushoma hwebarium nedzimwe simbi dzealkali kana alkaline earth metals. Sezvinhu zvechicherwa zvisiri zvesimbi, feldspar minerals dzakapararira zvakanyanya muganda renyika, uye ndidzo mineral dzinonyanya kupararira dzesilicate rock-forming kunze kwequartz. Inenge 60% yadzo inowanikwa mumatombo e magmatic, 30% mumatombo e metamorphic, uye 10% mumatombo e sedimentary, nehuremu hwese hwe50% hwehuremu hwese hwenyika. Kune isomorphism yakabudirira zvakanaka muzvicherwa zve feldspar, uye kuumbwa kwemakemikari kunowanzo ratidzwa ne OrxAbyAnz(x+y+z=100), apo Or, Ab naAn zvinomiririra zvikamu zvitatu zve potassium feldspar, albinite ne calcium feldspar, zvichiteerana.
Nzvimbo yekunyunguduka kwefeldspar inowanzo kuve inenge 1300℃, huwandu hwayo hunenge 2.58g/cm3, Kuomarara kweMos 6.5, simba remuchadenga rinochinja-chinja pakati pe2.5-3, rinopfumbira, rinodzivisa kudzvanywa, rinokwenya zvakanaka uye rinoita zviri nyore kupwanya. Kugadzikana kwakanaka kwemakemikari, rinodzivisa ngura, kunze kwekuwanda kwesulfuric acid nehydrofluoric acid; Rinobatsira kunyungudutsa, rinowanzoshandiswa seflux muindasitiri yeceramic negirazi; Rinoyera zvishoma refraction uye birefraction. Rine girazi rinopenya, asi rinowanzova neruvara rwakasiyana nekuti rine tsvina. Mazhinji emaminerari efeldspar anoshandiswa sezvinhu zvekugadzira magirazi neceramic, uye anogona zvakare kushandiswa pakurapa mafetiraiza, maabrasives nemidziyo, fiber yegirazi nedzimwe nzvimbo dzeindasitiri.
02 Zvinhu zvinokanganisa hunhu hwefeldspar
Chekutanga chinhu chine kugona kudhaya, senge Fe, Ti, V, Cr, Mn, Cu, nezvimwewo.
Mumamiriro ezvinhu akajairika, Fe naTi ndizvo zvinhu zvikuru zvekudhaya, zvimwe zvinhu zvirimo zvidiki kwazvo, mwero muchena hauna simba rakawanda.
Chikamu chechipiri chicherwa cherima, senge biotite, rutile, chlorite nezvimwewo. Huremu hwezvicherwa zverima mumatombo ezvicherwa hwakaderera, asi hune simba guru pamhando ye feldspar concentrate. Rudzi rwechitatu i organic carbon yakaiswa mu feldspar, iyo inopa ore ruvara rwegrey-dema. Kazhinji, organic carbon iri nyore kubviswa pakupisa kwakanyanya, uye kuchena kwayo hakuna zvakunobatsira. Zvinhu zvikuru zvezvigadzirwa zveindasitiri isimbi, titanium, nesimbi, uye pamusoro pechigadzirwa pachaonekwa mavara matema, calcium yakawanda zvakanyanya, pamusoro pechigadzirwa hapana kuenzana, saka kuti kuvandudza mhando yematombo marefu, kushandiswa kwedombo refu, huwandu hwezvicherwa zverima necalcium kunofanirwa kuderedzwa, kunyanya kubviswa kwesimbi oxide.
Kuvapo kwesimbi mufeldspar kunonyanya kuve nenzira dzinotevera: 1. Inonyanya kuve monomer kana aggregate ye hematite, magnetite uye limonite ine saizi ye particle ye >0.1mm. Yakaita sedenderedzwa, yakafanana netsono, yakafanana neflake kana isina kujairika, yakapararira zvakanyanya mu feldspar minerals uye iri nyore kubvisa. Chechipiri, pamusoro pefeldspar pakasvibiswa ne iron oxide muchimiro chekubuda kwemvura, kana pamwe chete nemaburi, zvicherwa uye majoini akatsemuka ekupararira kwe feldspar, iron oxide inoumbwa ne iron dye inowedzera kuoma kwekubvisa iron. Chechitatu, inowanikwa muchimiro che gangue minerals dzine iron, dzakadai se biotite, limonite, pyrite, ferrotitanium ore, amphibole, epidote nezvimwewo.
03 Nzira dzinoshandiswa zvakanyanya dzekugadzira feldspar ore
Parizvino, nzira huru yekucheneswa kwefeldspar ore yemumba inowanzo kuve "kupwanya - kupatsanura - kupatsanura kwemagnetic - kutenderera", zvichienderana nehuwandu hwakasiyana hwefeldspar mineral disadification uye hunhu hwakaiswa mugangue mineral, uye kupatsanura nemaoko, kubvisa, kupatsanura nezvimwe.
(1) kupwanya nekukuya
Kupwanya feldspar kwakakamurwa kuita kupwanya kwakakora uye kupwanya kwakakora. Mazhinji ematombo anofanira kupfuura nenzira mbiri dzekupwanya kwakakora uye kupwanya kwakakora. Kupwanya kwakakora chikamu chikuru chejaw crusher, michina yekupwanya inonyanya kushandisa impact type crusher, hammer type crusher, impact type crusher, nezvimwewo.
Kukuya kwefeldspar kunonyanya kukamurwa kuita kukuya kwakaoma uye kukuya kwakanyorova.
Kushanda zvakanaka kwekukuya kwakanyorova kwakakwira kupfuura kwekukuya kwakaoma, uye chiitiko che "kukuya zvakanyanya" hachisi nyore kuoneka. Midziyo yekukuya inonyanya kuve mill mill, rod mill, tower mill, sanding mill, vibration mill, airflow mill, nezvimwewo.
(2) Kugeza uye kubvisa ganda
Matombo eFeldspar paanenge achiumbwa anenge aine huwandu hwakati hwetsvina. Kusuka kunonyanya kuitirwa kubvisa tsvina yakaita sevhu, matope matete uye mica mufeldspar. Kusuka kunogona kuderedza huwandu hweFe.2O3muore, uye zvakare kuvandudza huwandu hweK2O naNa2Kusuka simbi kunoreva kuparadzanisa zvicherwa zvine matombo akakora pasi pemvura inoyerera nekushandisa hunhu hwezvinhu zvidiki uye kumhanya kunonoka kwevhu, matope akapfava uye mica. Midziyo inowanzoshandiswa yekuwachisa simbi ndeyekukwesha muchina, chinodedera chinovhara simbi uye tangi rekuwachisa simbi.
Chinangwa chikuru chekubvisa matope ndechekubvisa matombo emuno kubva mumatombo uye mamwe matombo epakati emhando yepakati yekukuya kwakapwanyika, uye kudzivirira mhedzisiro yekusarudzwa kwehupfu kunotevera. Midziyo inowanzoshandiswa yekubvisa matope ine hydraulic cyclone, classifier, centrifuge uye depuff.
(3) kupatsanurwa kwemagineti
Uchishandisa musiyano wemagineti pakati pematombo akasiyana-siyana, nzira yekubvisa simbi pasi pesimba remagineti rekunze inonzi kupatsanurwa kwemagineti. Feldspar haina magineti, asi Fe2O3uye mica mufeldspar ine simba remagineti, saka kana ichisimbisa simba remagineti rekunze, Fe2O3, mica nefeldspar zvinogona kupatsanurwa. Parizvino, michina yekuparadzanisa magineti inoshandiswa zvakanyanya muChina inosanganisira rare earth roller magnetic separator, permanent magnet drum magnetic separator, wet magnetic plate magnetic separator, vertical ring high gradient magnetic separator, electromagnetic slurry high gradient magnetic separator uye superconducting high intensity magnetic separator.
(4) kuyerera
Nzira yekudonha inoreva kuwedzerwa kwechinhu chinogadzirisa, chinounganidza, chinhu chinopupuma furo nezvimwe zvinhu zvinosanganisa pulp yekukuya, kuitira kuti tsvina yesimbi isanganiswe nebubble, kuitira kuti iyo ne pulp solution, uye wobva wabvisa michina, kuitira kuti tsvina yesimbi uye upfu hwakatsetseka hwezvinhu zvisina kucheneswa. Kudonha inzira inoshanda yekubvisa kusvibiswa kwefeldspar. Kune rumwe rutivi, kunogona kubvisa tsvina dzakadai sesimbi ne mica, uye kune rumwe rutivi, kunogona kuwedzera huwandu hwe potassium ne sodium. Kana mineral yakasiyana, sarudzo yechinhu chinobatwa yakasiyana, asi maitiro ekudonha anogona kushandiswa.
