01 lus
Feldspar yog ib qho ntawm cov ntxhia tshaj plaws nyob rau sab av loj.Nws cov khoom tseem ceeb suav nrog SiO2, Al2O3, K2Aw, Na2O thiab lwm yam.Nws muaj cov poov tshuaj, sodium, calcium thiab ib qho me me ntawm barium thiab lwm yam alkali hlau lossis alkaline ntiaj teb hlau.Raws li cov tswv yim tsis yog cov khoom siv hlau tsis zoo, cov khoom siv feldspar tau dav faib rau hauv lub ntiaj teb crust, thiab yog cov feem ntau faib cov pob zeb silicate pob zeb tsim tshwj tsis yog quartz.Txog 60% ntawm lawv tshwm sim hauv cov pob zeb magmatic, 30% hauv cov pob zeb metamorphic, thiab 10% hauv cov pob zeb sedimentary, nrog rau tag nrho qhov hnyav ntawm 50% ntawm lub ntiaj teb qhov hnyav tag nrho.Muaj ib qho zoo-tsim isomorphism nyob rau hauv feldspar minerals, thiab tshuaj. feem ntau hais los ntawm OrxAbyAnz(x + y + z = 100), qhov twg Or, Ab thiab An sawv cev peb lub ntsiab ntawm cov poov tshuaj feldspar, albinite thiab calcium feldspar, feem.
Lub melting point ntawm feldspar feem ntau yog hais txog 1300 ℃, qhov ceev yog li 2.58g / cm3.3Mos hardness 6.5, qhov tshwj xeeb lub ntiajteb txawj nqus fluctuates ntawm 2.5-3, nkig, compression tsis kam, zoo grindability thiab kev loj hlob kev ua tau zoo, yooj yim rau crush.Zoo tshuaj stability, corrosion kuj, tshwj xeeb tshaj yog siab concentration ntawm sulfuric acid thiab hydrofluoric acid; Pab yaj muaj nuj nqi, Feem ntau siv los ua flux nyob rau hauv ceramic thiab iav kev lag luam; Tsawg Performance index ntawm refraction thiab birefraction.Nws muaj ib tug glazed luster, tab sis feem ntau muaj ib tug txawv xim vim hais tias nws muaj impurities.Feldspar minerals feem ntau yog siv los ua raw cov ntaub ntawv rau iav thiab ceramic kev lag luam, thiab kuj tuaj yeem siv rau kev kho chiv, abrasives thiab cov cuab yeej, iav fiber ntau thiab lwm yam lag luam.
02 Yam cuam tshuam rau feldspar zoo
Thawj yog cov khoom muaj peev xwm dyeing, xws li Fe, Ti, V, Cr, Mn, Cu, thiab lwm yam.
Nyob rau hauv ib txwm muaj xwm txheej, Fe thiab Ti yog lub ntsiab dyeing ntsiab, lwm yam ntsiab lus me me, dawb degree tsis tshua muaj kev cuam tshuam.
Qhov thib ob yog cov zaub mov tsaus, xws li biotite, rutile, chlorite thiab lwm yam.Cov ntsiab lus ntawm cov ntxhia hauv cov pob zeb tsis muaj zog, tab sis nws muaj txiaj ntsig zoo rau qhov zoo ntawm feldspar concentrate.Qhov thib peb yog cov organic carbon deposited nrog. feldspar, uas muab cov ore xim grey-dub. Feem ntau, cov organic carbon yog ib qho yooj yim kom tshem tawm ntawm qhov kub thiab txias, thiab cov xim dawb muaj cov nyhuv me me.Cov ntsiab lus tseem ceeb ntawm cov khoom lag luam yog hlau, titanium, thiab hlau, thiab saum npoo ntawm cov khoom yuav tshwm dub me ntsis, cov ntsiab lus calcium yog siab dhau, qhov saum npoo ntawm cov khoom tsis sib xws, yog li txhawm rau txhim kho qhov zoo ntawm cov pob zeb ntev ntev, daim ntawv thov ntawm cov pob zeb ntev, cov ntsiab lus ntawm cov ntxhia tsaus thiab calcium yuav tsum tau txo, tshwj xeeb tshaj yog tshem tawm cov hlau oxide.
Lub hav zoov ntawm cov hlau nyob rau hauv feldspar feem ntau muaj cov ntaub ntawv hauv qab no: 1. Nws yog monomer los yog aggregate ntawm hematite, magnetite thiab limonite nrog particle loj ntawm> 0.1mm.Nws yog spherical, koob zoo li, flakelike los yog irregular, heev dispersed nyob rau hauv feldspar minerals thiab yooj yim rau tshem tawm. Thib ob, lub nto ntawm feldspar yog polluted los ntawm hlau oxide nyob rau hauv daim ntawv ntawm seepage, los yog raws li cov kab nrib pleb, minerals thiab cleavage pob qij txha ntawm feldspar. nkag mus rau hauv kev faib tawm, cov hlau oxide tsim los ntawm cov hlau zas xim zoo heev ua rau muaj kev nyuaj ntawm kev tshem tawm hlau. Thirdly, nws muaj nyob rau hauv daim ntawv ntawm hlau-bearing gangue minerals, xws li biotite, limonite, pyrite, ferrotitanium ore, amphibole, epidote thiab hais txog.
03 Feem ntau siv cov txiaj ntsig ntawm feldspar ore
Tam sim no, cov txheej txheem tseem ceeb ntawm cov khoom siv hauv tsev feldspar ore purification yog feem ntau "sib tsoo - sib tsoo kev faib tawm - sib nqus sib nqus - flotation", raws li cov ntsiab lus sib txawv feldspar ntxhia impurity thiab gangue mineral embedded yam ntxwv, thiab tes sib cais, desudging, kev faib tawm thiab lwm yam haujlwm.
(1) crushing thiab sib tsoo
Lub crushing ntawm feldspar yog muab faib ua ntxhib crushing thiab nplua crushing.Feem ntau cov ores yuav tsum mus los ntawm ob txheej txheem ntawm ntxhib crushing thiab nplua crushing.Coarse crushing feem ntau ntawm lub puab tsaig crusher, crushing khoom mas feem ntau yam crusher, rauj hom crusher, yam hom crusher, thiab lwm yam.
Kev sib tsoo ntawm feldspar feem ntau muab faib rau hauv kev sib tsoo qhuav thiab sib tsoo ntub.
Kev sib tsoo ntub dej yog siab dua qhov kev sib tsoo qhuav, thiab qhov tshwm sim ntawm "kev sib tsoo" tsis yooj yim tshwm sim. Cov khoom siv sib tsoo feem ntau yog pob zeb, pas nrig zeb, ntauwd zeb, xuab zeb zeb, vibration zeb, airflow zeb, lwm.
(2) Ntxuav thiab desliming
Feldspar ore nyob rau hauv tus txheej txheem ntawm kev tsim ntau los yog tsawg yuav muaj ib tug npaum li cas ntawm slime.Kev ntxuav yog tsuas yog tshem tawm impurities xws li av nplaum, nplua av nkos thiab mica nyob rau hauv feldspar.Kev ntxuav yuav txo tau cov ntsiab lus ntawm Fe.2O3nyob rau hauv ore, thiab kuj txhim kho cov ntsiab lus ntawm K2O and Na2O.Ore ntxuav yog cais tawm ntawm coarse-grained minerals nyob rau hauv qhov kev txiav txim ntawm cov dej ntws los ntawm kev ua kom zoo dua ntawm cov yam ntxwv ntawm cov me me particle loj thiab qeeb qeeb ceev ntawm av nplaum, nplua av nkos thiab mica.Cov khoom siv ore ntxhua khaub ncaws yog siv los txhuam, vibrating npo thiab ore ntxuav tank.
Lub hom phiaj tseem ceeb ntawm kev tshem tawm cov av nkos yog tshem tawm cov haiv neeg ore los ntawm cov ore thiab cov ore thib ob ntawm cov khoom nruab nrab ntawm cov txheej txheem sib tsoo tawg, thiab tiv thaiv cov nyhuv ntawm kev xaiv cov hmoov tom ntej.Cov khoom siv feem ntau siv deputer muaj hydraulic cyclone, classifier, centrifuge thiab depuff.
(3) sib nqus sib nqus
Siv cov hlau nplaum sib txawv ntawm ntau yam ores, cov txheej txheem ntawm kev tshem tawm hlau nyob rau hauv qhov kev txiav txim ntawm sab nraud magnetic teb yog hu ua magnetic separation.Feldspar tsis muaj hlau nplaum, tab sis Fe2O3thiab mica hauv feldspar muaj zog hlau nplaum tsis muaj zog, yog li nyob rau hauv cov xwm txheej ntawm kev ntxiv dag zog rau sab nraud magnetic teb, Fe2O3, mica thiab feldspar tuaj yeem sib cais. Sib nqus sib nqus, ntub sib nqus phaj sib nqus sib nqus cais, ntsug nplhaib siab gradient sib nqus separator, electromagnetic slurry siab gradient sib nqus separator thiab superconducting siab siv hlau nplaum sib cais.
(4) flotation
Flotation method yog hais txog qhov sib ntxiv ntawm kev hloov kho tus neeg sawv cev, tus neeg sau, tus neeg sawv cev foaming thiab lwm tus neeg sawv cev hauv kev sib tsoo cov ntaub ntawv nyoos, kom cov hlau impurities txuas nrog npuas, kom nws thiab cov kua pulp, thiab tom qab ntawd txhua yam scraping tawm, yog li ntawd. cov hlau impurities thiab raw khoom zoo hmoov sib cais.Flotation yog ib txoj hauv kev zoo tshem tawm impurity ntawm feldspar.Ntawm qhov tod tes, nws tuaj yeem tshem tawm cov impurities xws li hlau thiab mica, thiab ntawm qhov tod tes, nws tuaj yeem ua rau cov ntsiab lus ntawm cov poov tshuaj thiab sodium.Thaum cov ntxhia sib txawv, qhov kev xaiv ntawm kev ntes tus neeg sawv cev txawv, tab sis cov txheej txheem rov qab flotation. tuaj yeem txais yuav.
