Feldspar nimwe mumabuye y'agaciro akunze kugaragara kumugabane wumugabane. Ibigize byingenzi birimo SiO2, Al2O3, K.2O, Na2O n'ibindi. Irimo 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 kwitwa quartz. Abagera kuri 60% muri bo biboneka mu bitare bya magatiki, 30% mu bitare bya metamorphique, na 10% mu bitare byimeza, bifite uburemere bwa 50% by’uburemere bw’isi.Hariho isomorphism yateye imbere neza mu myunyu ngugu ya feldspar, hamwe n’imiti ibihimbano bikunze kugaragazwa na OrxAbyAnz(x + y + z = 100), aho Or, Ab na An byerekana ibice bitatu bya potasiyumu feldspar, albinite na calcium feldspar, kimwe.
Ahantu ho gushonga kwa feldspar muri rusange ni 1300 ℃, ubucucike ni 2.58g / cm3, Ubukomezi bwa Mos 6.5, uburemere bwihariye buhindagurika hagati ya 2,5-3, gucika intege, kurwanya compression, gusya neza hamwe niterambere ryiterambere, byoroshye kumenagura. Umutekano 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 yibirahure nizindi nganda.
02 Ibintu bigira ingaruka nziza kuri feldspar
Iya mbere ni ikintu gifite ubushobozi bwo gusiga irangi, 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.Ibigize 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, iha ubutare ibara ry'umukara-umukara. Mubihe byinshi, karubone kama iroroshye kuvanwaho mubushyuhe bwinshi, kandi umweru ntugire ingaruka nke.Ibintu nyamukuru byibicuruzwa byinganda ni ibyuma, titanium, nicyuma, n'ubuso bwibicuruzwa bizagaragara ibibara byirabura, karisiyumu ni ndende cyane, ubuso bwibicuruzwa ntiburinganiye, kugirango rero uzamure ubwiza bwamabuye y'agaciro 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, bisa ninshinge, flakelike cyangwa bidasanzwe, bikwirakwijwe cyane mumabuye ya feldspar kandi byoroshye kuyikuramo. Icya kabiri, ubuso bwa feldspar bwandujwe na okiside yicyuma muburyo bwa seepage, cyangwa kuruhande rwacitse, imyunyu ngugu hamwe nuduce twa feldspar gukwirakwiza penetensiya, okiside yicyuma ikozwe n irangi ryicyuma byongera cyane ingorane zo gukuramo ibyuma.Icya gatatu, ibaho muburyo bwamabuye y'agaciro ya gangue, nka biotite, limonite, pyrite, ubutare bwa 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 "guhonyora - gusya ibyiciro - gutandukanya magnetiki - flotation", ukurikije ibintu bitandukanye byanduye bya feldspar hamwe n’amabuye y'agaciro ya gangue, hamwe no gutandukanya amaboko, gusebanya, gushyira mu byiciro n'ibindi bikorwa.
(1) guhonyora 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 ingaruka zo mu bwoko bwa crusher, ubwoko bwinyundo, inkoni yubwoko, 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 rwinkoni, urusyo rwumunara, urusyo rwumucanga, urusyo runyeganyega, urusyo rwo mu kirere, n'ibindi
(2) Gukaraba no gusiba
Amabuye ya Feldspar mugikorwa cyo gushingwa byinshi cyangwa bike bizaba birimo urugero rwa sime.Kwoza cyane cyane kugirango ukureho umwanda nkibumba, icyondo cyiza 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 yuzuye bitewe nigikorwa cyamazi yifashishije ibiranga ingano ntoya hamwe no gutinda gutinda kw ibumba, ibyondo byiza na mika.Ibikoresho bikoreshwa cyane byo gukaraba amabuye ni imashini isuzuma, kunyeganyeza ecran hamwe no gukaraba amabuye.
Intego nyamukuru yo gukuraho icyondo ni ugukuraho ubutare kavukire mu bucukuzi n’amabuye ya kabiri yo mu cyiciro cyo hagati cyo gusya kwacitse, no gukumira ingaruka zo gutoranya ifu. Ibikoresho bisanzwe bikoreshwa mu mahanga 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 byitwa gutandukanya magnetiki.Feldspar ntigira magnetisme, ariko Fe2O3na mika muri feldspar bifite magnetisme idakomeye, kuburyo rero muburyo bwo gushimangira umurima wa magnetiki wo hanze, Fe2O3, mika na feldspar birashobora gutandukana. Kugeza ubu, ibikoresho byo gutandukanya magnetiki bikunze gukoreshwa mubushinwa ahanini birimo isi idasanzwe ya rukuruzi itandukanya, ingoma ya magneti ihoraho itandukanya magnetiki, itose ya magnetiki itandukanya magnetiki itandukanya, impeta ihagaritse impagarike ndende ya magnetiki itandukanya, electromagnetic slurry high gradient magnetic itandukanya hamwe na superconducting ubukana bukomeye bwa magnetiki.
(4) flotation
Uburyo bwa Flotation bivuga kongeramo ibikoresho byo kugenzura, gukusanya, gukora ifuro nizindi miti mugusya ibikoresho bibisi, 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.
