Feldspar yog ib qho ntawm cov pob zeb tseem ceeb tshaj plaws hauv lub ntiaj teb lub plhaub. Potassium lossis sodium-nplua nuj feldspar siv dav hauv cov khoom siv av nplaum, enamel, iav, abrasives, thiab lwm yam kev lag luam. Potassium feldspar, vim nws muaj cov potassium ntau thiab yog cov khoom siv potassium uas tsis yaj hauv dej, tuaj yeem siv yav tom ntej rau kev tsim cov chiv potash, ua rau nws yog cov khoom siv tseem ceeb rau kev tswj hwm. Feldspar uas muaj cov ntsiab lus tsis tshua muaj xws li rubidium thiab cesium tuaj yeem ua lub hauv paus rau kev rho tawm cov ntsiab lus no. Feldspar xim zoo nkauj tuaj yeem siv ua pob zeb dai kom zoo nkauj thiab cov pob zeb semi-precious.
Sib nrug los ntawm kev ua cov khoom siv raw rau kev lag luam iav (suav txog li 50-60% ntawm tag nrho cov kev siv), feldspar kuj tseem siv rau hauv kev lag luam ceramics (30%), nrog rau lwm yam siv rau hauv cov tshuaj lom neeg, abrasives, fiberglass, welding electrodes, thiab lwm yam lag luam.
Iav Flux
Feldspar yog ib qho ntawm cov khoom tseem ceeb ntawm cov iav sib xyaw. Nrog cov ntsiab lus Al₂O₃ siab thiab cov ntsiab lus hlau qis, feldspar yaj ntawm qhov kub qis dua thiab muaj ntau yam yaj. Nws feem ntau yog siv los ua kom cov ntsiab lus alumina hauv cov iav sib xyaw, txo qhov kub yaj, thiab ua kom cov ntsiab lus alkali nce ntxiv, yog li txo cov alkali siv. Tsis tas li ntawd, feldspar yaj qeeb qeeb rau hauv iav, tiv thaiv kev tsim cov siv lead ua uas tuaj yeem ua puas cov khoom. Feldspar kuj pab tswj qhov viscosity ntawm iav. Feem ntau, potassium lossis sodium feldspar siv rau hauv ntau yam iav sib xyaw.
Cov Khoom Xyaw Rau Lub Cev Uas Ua Los Ntawm Cov Khoom ...
Ua ntej hlawv, feldspar ua haujlwm ua cov khoom siv raw thinning, txo qhov ziab shrinkage thiab deformation ntawm lub cev, txhim kho kev ua kom qhuav, thiab luv lub sijhawm ziab. Thaum hlawv, feldspar ua haujlwm ua cov kua dej los txo qhov kub hlawv, txhawb kev yaj ntawm quartz thiab kaolin, thiab pab txhawb kev tsim cov mullite hauv theem kua. Lub iav feldspar tsim thaum lub sijhawm yaj puv cov mullite siv lead ua ke hauv lub cev, ua rau nws denser thiab txo porosity, yog li ua rau nws lub zog kho tshuab thiab dielectric zog. Tsis tas li ntawd, kev tsim cov iav feldspar txhim kho qhov translucency ntawm lub cev. Tus nqi ntawm feldspar ntxiv rau hauv cov khoom siv ceramic sib txawv raws li cov khoom siv raw thiab cov khoom xav tau.
Cov Khoom Siv Ua Los Ntawm Av nplaum
Cov khoom siv ua los ntawm cov av nplaum feem ntau yog ua los ntawm feldspar, quartz, thiab av nplaum, nrog rau cov feldspar uas muaj li ntawm 10-35%. Hauv kev lag luam ua los ntawm cov av nplaum (ob qho tib si lub cev thiab cov khoom siv ua los ntawm cov av nplaum), potassium feldspar feem ntau yog siv.
Cov Khoom Siv Lub Cev thiab Tshuaj
Feldspar yog ib yam khoom siv uas muaj nyob thoob plaws ntiaj teb, nrog rau cov potassium ntau hu ua potassium feldspar, uas yog KAlSi₃O₈. Orthoclase, microcline, thiab sanidine yog cov khoom siv potassium feldspar. Cov feldspars no muaj kev ruaj khov zoo thiab feem ntau tiv taus acid decomposition. Lawv muaj qhov nyuaj ntawm 5.5-6.5, qhov hnyav tshwj xeeb ntawm 2.55-2.75 t/m³, thiab qhov kub yaj ntawm 1185-1490°C. Cov khoom siv feem ntau suav nrog quartz, muscovite, biotite, beryl, garnet, thiab me me ntawm magnetite, columbite, thiab tantalite.
Kev faib tawm ntawm Feldspar Deposits
Cov nyiaj tso rau hauv Feldspar feem ntau yog muab faib ua ob hom raws li lawv keeb kwm:
1. **Gneiss lossis Migmatitic Gneiss**: Qee cov leeg ntshav tshwm sim hauv granite lossis cov pob zeb yooj yim, lossis hauv lawv cov cheeb tsam sib cuag. Cov hlau feem ntau yog nyob rau hauv thaj chaw feldspar thaiv ntawm pegmatites lossis differentiated feldspar pegmatites.
2. **Cov Pob Zeb Feldspar Hom Igneous**: Cov pob zeb no tshwm sim hauv cov pob zeb igneous uas muaj kua qaub, nruab nrab, thiab alkaline. Cov uas pom muaj nyob rau hauv cov pob zeb alkaline yog cov tseem ceeb tshaj plaws, xws li nepheline syenite, ua raws li granite, albite granite, orthoclase granite, thiab quartz orthoclase granite deposits.
Raws li cov txheej txheem mineralization ntawm feldspar, feldspar deposits raug muab faib ua igneous rock hom, pegmatite hom, weathered granite hom, thiab sedimentary rock hom, nrog pegmatite thiab igneous rock hom yog cov tseem ceeb.
Cov Txheej Txheem Sib Cais
- **Kev Xaiv Los Ntawm Tes**: Raws li qhov sib txawv ntawm cov duab thiab xim los ntawm lwm cov minerals gangue, kev xaiv los ntawm tes yog siv.
- **Kev Sib Cais Sib Nqus**: Tom qab tsoo thiab sib tsoo, cov khoom siv sib cais sib nqus xws li cov phaj sib nqus sib cais, LHGC vertical ring high gradient magnetic separators, thiab HTDZ electromagnetic slurry magnetic separators raug siv los tshem tawm cov hlau tsis muaj zog, titanium, thiab lwm yam minerals impurity rau kev ntxuav.
- **Flotation**: Feem ntau siv HF acid nyob rau hauv cov xwm txheej acidic, nrog amine cations ua cov khoom sau rau kev sib cais feldspar ntawm quartz.
