Wolframite thiab scheelite yog ob hom tungsten ore, thiab ob qho tib si tuaj yeem siv los tsim ammonium para tungstate (APT), tab sis vim lawv cov qauv siv lead ua sib txawv thiab impurities, cov txheej txheem siv los tsim APT kuj txawv: wolframite APT yog npaj los ntawm high-pressure alkali ua noj ion pauv-evaporation crystallization txoj kev, thiab scheelite mloog zoo yog npaj los ntawm dej qab zib siab ua noj hnyav extraction-evaporation crystallization txoj kev. Dab tsi yog qhov txawv ntawm wolframite thiab scheelite? Lub tuam txhab luv luv qhia cov ntsiab lus hauv qab no:

|
1. Lub npe txawv: wolframite, tseem hu ua wolframite, yog Wolframite hauv lus Askiv; scheelite yog Scheelite hauv lus Askiv.
2. Cov tshuaj sib txawv: wolframite feem ntau yog tsim los ntawm tungstenite (FeWO4) thiab wolframite (MnWO4), uas wolframite muaj 23.65 feem pua FeO thiab 76.35 feem pua WO3, wolframite muaj 23.42 feem pua MnO thiab 76.58 feem pua WO. Cov ntsiab lus tseem ceeb ntawm scheelite yog calcium tungstate (CaWO4), uas muaj 19.47 feem pua ntawm CaO thiab 80.53 feem pua ntawm WO3.
3. Cov qauv sib txawv: wolframite muaj ob hom: monoclinic siv lead ua system thiab orthorhombic kem siv lead ua, cov siv lead ua daim ntawv yog phaj-zoo li lossis kem-zoo li, thiab cov aggregate feem ntau yog phaj-zoo li; Aggregates yog feem ntau tsis sib xws granular, tsawg ntom blocks.
4. Cov xim sib txawv: xim wolframite yuav tsaus dua nrog qhov nce ntawm cov ntsiab lus hlau, feem ntau los ntawm xim av mus rau xim dub; scheelite feem ntau yog grey, lub teeb daj, lub teeb liab, lossis lub teeb xim av.
5. txawv lus: wolframite muaj xim hlau luster lossis semi-hlau luster; scheelite muaj vitreous luster los yog pob zeb diamond luster.
6. Txawv pob tshab: wolframite tsis meej; scheelite yog pob tshab rau translucent.
7. Cov streaks sib txawv: wolframite streaks yog xim sib dua, tungsten manganese ore yog daj-xim av-daj, tungsten hlau ore yog xim av-xim av; scheelite streaks yog daj-ntsuab.
Yim hom mineralization yog txawv: wolframite muaj gristite hom, quartz leeg hom, porphyry hom, thiab lwm yam mineralization hom; scheelite feem ntau yog tsim nyob rau hauv kev sib cuag metasomatic skarn, high-temperature hydrothermal veins, thiab granite pob zeb.
9. Ntau lub hauv paus chiv keeb: yav qab teb Jiangxi, sab hnub tuaj Hunan, thiab sab qaum teb Guangdong yog cov chaw tsim khoom tseem ceeb ntawm wolframite, thaum Russia, Siberia, Myanmar, Thaib, Australia, Bolivia, thiab lwm qhov chaw kuj muaj cov ore no; Hunan Yaogangxian yog scheelite. Nws yog qhov chaw tsim khoom tseem ceeb ntawm cov ore, thiab cov ore tseem pom nyob rau hauv Shantang nyob rau sab qab teb Kauslim Teb, Saxony hauv lub teb chaws Yelemees, New South Wales hauv Australia, sab qaum teb Bolivia, thiab Nevada hauv Tebchaws Meskas.
