Feldspar nimwe mumabuye y'agaciro akunze kugaragara kumugabane wumugabane.Ibigize byingenzi birimo SiO2, Al2O3, K.2Kuri2O n'ibindi.Harimo potasiyumu, sodium, calcium hamwe na barium nkeya hamwe nibindi byuma bya alkali cyangwa ubutaka bwa alkaline.Nkibikorwa byubutare butari ubutare, amabuye y'agaciro ya feldspar akwirakwizwa cyane mubutaka bwisi, kandi ni amabuye y'agaciro ya silikatike akwirakwizwa cyane usibye quartz.Hafi ya 60% muribo biboneka mumabuye ya magatiki, 30% mubutare bwa metamorphic, na 10% mubutare bwimitsi, hamwe nuburemere bwa 50% byuburemere bwisi yose.Hariho isomorphism yateye imbere mumabuye y'agaciro ya feldspar, hamwe na chimique ibihimbano bikunze kugaragazwa na OrxAbyAnz(x + y + z = 100), aho Or, Ab na An byerekana ibice bitatu bya potasiyumu feldspar, albinite na calcium feldspar.
Ingingo yo gushonga ya feldspar muri rusange ni 1300 ℃, ubucucike ni 2.58g / cm3, Ubukomezi bwa Mos 6.5, uburemere bwihariye buhindagurika hagati ya 2,5-3, kuvunika, kurwanya compression, gusya neza hamwe niterambere ryiterambere, byoroshye kumenagura. Umutimanama mwiza wimiti, kurwanya ruswa, usibye kuba mwinshi wa acide sulfurike na aside hydrofluoric; Ifasha gushonga imikorere, bikunze gukoreshwa nka flux mu nganda zubutaka n’ibirahure; Indangantego yo kugabanuka no kugabanwa.Bifite urumuri rwikirahure, ariko akenshi rufite ibara ritandukanye kuko ririmo umwanda. Amabuye y'agaciro ya feldspar akoreshwa nkibikoresho fatizo byinganda n’ibirahure, na, irashobora kandi gukoreshwa mugutunganya ifumbire, gukuramo ibikoresho, fibre yikirahure nizindi nganda.
02 Ibintu bigira ingaruka kumiterere ya feldspar
Iya mbere ni ikintu gifite ubushobozi bwo gusiga, nka Fe, Ti, V, Cr, Mn, Cu, nibindi.
Mubihe bisanzwe, Fe na Ti nibintu nyamukuru byo gusiga irangi, ibindi bintu birimo ni bito cyane, urwego rwera rufite imbaraga nke.
Icyiciro cya kabiri ni imyunyu ngugu yijimye, nka biotite, rutile, chlorite nibindi.Ibirimo imyunyu ngugu yijimye mu rutare rwamabuye y'agaciro ni bike, ariko bigira uruhare runini ku bwiza bwa feldspar. Ubwoko bwa gatatu ni karubone kama yabitswe hamwe feldspar, itanga ubutare ibara ryumukara-umukara.Mu bihe byinshi, karubone kama iroroshye kuvanwaho mubushyuhe bwinshi, kandi umweru ntigira ingaruka nke.Ibintu nyamukuru byibicuruzwa byinganda ni ibyuma, titanium, nicyuma, n'ubuso bwibicuruzwa bizagaragaraho ibibara byirabura, karisiyumu ni ndende cyane, ubuso bwibicuruzwa ntiburinganiye, kugirango uzamure ubwiza bwamabuye maremare maremare, gukoresha amabuye maremare, ibirimo amabuye y'agaciro yijimye na calcium igomba kugabanuka, cyane cyane kuvanaho okiside ya fer.
Kubaho kwicyuma muri feldspar ahanini bifite uburyo bukurikira: 1. Ni monomer cyangwa igiteranyo cya hematite, magnetite na limonite hamwe nubunini bwa> 0.1mm.Nibisanzwe, urushinge rumeze, flakelike cyangwa idasanzwe, ikwirakwijwe cyane mumabuye ya feldspar kandi biroroshye kuyikuramo. Icya kabiri, ubuso bwa feldspar bwandujwe na okiside yicyuma muburyo bwa seepage, cyangwa kuruhande, ibice, amabuye y'agaciro hamwe na clavage ya feldspar gukwirakwiza penetensiya, okiside yicyuma ikorwa n irangi ryicyuma byongera cyane ingorane zo gukuramo ibyuma.Icya gatatu, ibaho muburyo bwamabuye y'agaciro ya gangue, nka biotite, limonite, pyrite, ferrotitanium, amphibole, epidote nibindi.
03 Uburyo bukoreshwa muburyo bwo kugirira akamaro ubutare bwa feldspar
Kugeza ubu, inzira nyamukuru yo kweza amabuye yo mu rugo ya feldspar muri rusange ni "kumenagura - gusya ibyiciro - gutandukanya magnetiki - flotation", ukurikije ibintu bitandukanye byanduye bya feldspar hamwe nibiranga amabuye y'agaciro ya gangue, hamwe no gutandukanya intoki, gusebanya, gushyira mubikorwa nibindi bikorwa.
（1） kumenagura no gusya
Kumenagura feldspar bigabanyijemo guhonyora no guhonyora neza.Amabuye y'agaciro menshi agomba kunyura muburyo bubiri bwo guhonyora no guhonyora neza. Kumenagura cyane igice kinini cyo mu rwasaya, ibikoresho byo kumenagura cyane cyane ubwoko bwa crusher, ubwoko bwinyundo, igikonjo cyubwoko, nibindi.
Gusya kwa feldspar bigabanijwemo cyane gusya byumye no gusya neza.
Imikorere yo gusya itose irarenze iyo gusya byumye, kandi ibintu byo "gusya cyane" ntabwo byoroshye kugaragara.Ibikoresho byo gusya ni urusyo rwumupira, urusyo, umunara, urusyo, urusyo, urusyo, n'ibindi.
（2） Gukaraba no gusiba
Amabuye ya Feldspar mugikorwa cyo gushiraho byinshi cyangwa bike bizaba birimo urugero rwa sime.Kwoza cyane cyane kugirango ukureho umwanda nkibumba, ibyondo byiza na mika muri feldspar.Kwoza birashobora kugabanya ibiri muri Fe2O3mu bucukuzi, kandi tunatezimbere ibikubiye muri K.2O na Na2O.Kwoza cyane ni ugutandukanya namabuye y'agaciro atoboye bitewe nigikorwa cyamazi ukoresheje ibintu biranga ingano ntoya hamwe no gutinda buhoro bwibumba, ibyondo byiza na mika.Ibikoresho bikoreshwa cyane byo gukaraba amabuye ni imashini isuzuma, kunyeganyega na ecran yo gukaraba.
Intego nyamukuru yo gukuraho icyondo ni ugukuraho ubutare kavukire mu bucukuzi bw’amabuye hamwe n’ubutare bwa kabiri bwo mu cyiciro cyo hagati cyo gusya, no gukumira ingaruka zo guhitamo ifu.Ibikoresho bisanzwe bikoreshwa mubikoresho bifite hydraulic cyclone, classifier, centrifuge na depuff.
（3） gutandukanya magnetiki
Ukoresheje itandukaniro rya magneti hagati yamabuye atandukanye, inzira yo gukuraho ibyuma munsi yumurimo wa magnetiki wo hanze witwa magnetique.Feldspar ntigira magnetisme, ariko Fe2O3na mika muri feldspar bifite magnetisme idakomeye, kuburyo rero muburyo bwo gukomeza imbaraga za magnetiki zo hanze, Fe2O3, mika na feldspar zirashobora gutandukana. Kugeza ubu, ibikoresho bisanzwe bitandukanya magnetique mubushinwa ahanini birimo isi idasanzwe ya rukuruzi itandukanya, ingoma ya rukuruzi ihoraho itandukanyirizo rya magneti, itandukanya magnetiki itandukanya magnetiki itandukanya, impeta ihagaritse impagarike ya magnetiki itandukanya, electromagnetic slurry high gradient magnetic itandukanya na superconducting ubukana bwa magnetiki itandukanya.
（4） flotation
Uburyo bwa Flotation bivuga kongeramo ibikoresho byo gukusanya, kwegeranya, ibibyimba hamwe nibindi bikoresho byo gusya ibikoresho fatizo, kugirango umwanda wicyuma ufatanye nigituba, kuburyo hamwe nigisubizo cya pulp, hanyuma ugakuraho imashini, kugirango umwanda wibyuma nibikoresho fatizo gutandukanya ifu nziza.Flotation nuburyo bwiza bwo gukuraho umwanda wa feldspar.Ku ruhande rumwe, irashobora gukuraho umwanda nka fer na mika, kurundi ruhande, irashobora kongera ibirimo potasiyumu na sodium.Iyo imyunyu ngugu itandukanye, guhitamo umukozi wo gufata biratandukanye, ariko inzira yo guhinduranya flotation irashobora kwakirwa.
