Feldspar yog ib qho aluminosilicate mineral ntawm alkali hlau thiab alkaline earth hlau xws li potassium, sodium thiab calcium. Nws muaj ib tsev neeg loj heev thiab yog cov minerals uas tsim pob zeb feem ntau. Nws tshwm sim dav hauv ntau yam pob zeb magmatic thiab metamorphic pob zeb, suav txog li 50% ntawm tag nrho cov crust, uas kwv yees li 60% ntawm cov feldspar ore tshwm sim hauv cov pob zeb magmatic. Lub feldspar mine feem ntau yog tsim los ntawm potassium thiab albite nplua nuj hauv potassium lossis sodium, thiab nws txoj kev loj hlob hauv ceramics, kev lag luam tub rog, kev lag luam tshuaj lom neeg, kev tsim kho thiab lwm yam lag luam yog "lub zog tseem ceeb". Nws feem ntau yog siv ua cov khoom siv raw rau kev lag luam iav los tsim cov khoom iav xws li iav tiaj tus, iav thiab iav fiber; qhov thib ob, nws yog siv ua cov khoom siv raw rau ceramics thiab glaze los tsim cov vuas phab ntsa, tshuaj ceramics, hluav taws xob ceramics thiab zeb linings; nws feem ntau yog siv ua cov khoom siv raw tshuaj rau kev tsim cov roj hmab thiab yas fillers thiab kev tsim cov tshuaj chiv, thiab lwm yam; thaum siv ua cov ntaub ntawv tsim kho, nws feem ntau tsim cov cement tshwj xeeb thiab iav fiber.

Nws tau tsim los ntawm Tuam Tshoj Non-metallic Mining Industry Association, thiab Ministry of Natural Resources tau tshaj tawm thiab siv tus qauv ntawm "Cov Lus Qhia rau Kev Tsim Kho Ntsuab hauv Kev Lag Luam Tsis Yog Hlau". Kev ua haujlwm qhia txog kev tsim khoom ntse hauv ob qho tseem ceeb ntawm "kev tsim khoom siv" thiab "kev tsim khoom" tau ua tiav, uas tau txhawb nqa kev txhim kho tob ntawm kev tsim khoom ntse hauv kev lag luam tsis yog hlau. Tau teeb tsa thiab ua kev tshawb fawb txog cov thev naus laus zis tshiab thiab cov txheej txheem tshiab xws li kev siv tshuab ua kom tob tsis muaj tailing, kev sib tsoo qhuav thiab kev ntxuav tshuab, thiab kev npaj cov ntaub ntawv porous los ntawm cov zaub mov silicate; ua tiav kev tsim cov sib cais sib nqus loj, cov sib cais sib nqus superconducting, cov kab ntau lawm ultra tiav rau kev sib tsoo, kev ntsuas zoo thiab kev hloov kho, cov khoom siv ntsuas qhov tseeb thiab lwm yam cuab yeej tshiab thiab cov khoom siv tshiab.
Tuam Tshoj yog ib lub teb chaws uas muaj cov peev txheej loj ntawm feldspar ore. Cov peev txheej ntawm feldspar ore ntawm ntau qib yog 40.83 lab tons. Feem ntau ntawm cov chaw tso nyiaj yog pegmatite deposits, uas kuj yog cov hom tseem ceeb ntawm cov chaw tso nyiaj tam sim no tsim thiab siv. Raws li Tuam Tshoj Lub Tsev Tsim Khoom Siv Kev Lag Luam Txheem (JC / T-859-2000), feldspar ore tau muab faib ua ob pawg (potassium feldspar, albite) thiab peb qib (khoom zoo tshaj plaws, khoom zoo tshaj plaws, khoom tsim nyog). Hauv Anhui, Shanxi, Shandong, Hunan, Gansu, Liaoning, Shaanxi thiab lwm qhov chaw.
Raws li cov ntsiab lus ntawm potassium, sodium, silicon thiab lwm yam ntsiab lus, kev siv tseem ceeb ntawm cov zaub mov feldspar kuj txawv. Feldspar beneficiation txoj kev yog feem ntau magnetic sib cais thiab flotation. Magnetic sib cais feem ntau siv ntub zog magnetic sib cais, uas yog rau lub cev txoj kev beneficiation, kev tiv thaiv ib puag ncig thiab tsis muaj kuab paug, thiab yog tsim rau kev tshem tawm hlau thiab purification ntawm feldspar ore ntawm ntau yam khoom. Cov xwm txheej tshwj xeeb xws li embedded yam ntxwv thiab xaiv qhov loj me me yog xaiv los ntawm ntau lub zog teb thiab cov khoom siv sib cais sib nqus rau kev cais, tab sis lub zog teb sib nqus yog qhov yuav tsum tau siab dua 1.0T.

Tsim cov txheej txheem zoo rau cov feldspar ore ntawm cov khoom sib txawv: rau pegmatite-hom feldspar ore, cov khoom siv lead ua los ntawm cov pob zeb loj thiab yooj yim cais. , qhov txiaj ntsig zoo thiab tus phooj ywg ib puag ncig; rau feldspar nrog cov ntsiab lus quartz siab, cov txheej txheem ua ke ntawm kev sib cais sib nqus muaj zog thiab flotation feem ntau yog siv, uas yog crushing-grinding-classification-muaj zog sib cais sib nqus-flotation. Kev sib cais sib nqus ua ntej tshem tawm cov khoom tsis huv xws li hlau oxide thiab biotite, thiab tom qab ntawd siv flotation los cais feldspar thiab quartz kom tau txais ob yam khoom zoo. Ob qho txheej txheem zoo saum toj no tau ua tiav lub hom phiaj ntawm kev ua kom yooj yim thiab ua haujlwm tau zoo hauv kev ua kom zoo ntawm feldspar ore, thiab tau txhawb nqa thiab siv dav.
