Qhia luv luv ntawm Tungsten Ore thiab Concentrate

Raws li peb txhua tus paub, tungsten carbides yog tsim los ntawm tungsten ore. Thiab hauv tsab xov xwm no, koj tuaj yeem saib los ntawm qee cov ntaub ntawv hais txog tungsten ore thiab mloog zoo. Kab lus no yuav piav qhia txog tungsten ores thiab mloog zoo rau cov hauv qab no:

1. Kev taw qhia luv luv ntawm tungsten ore thiab mloog zoo;

2. Ntau hom tungsten ore thiab concentrated

3. Daim ntawv thov ntawm tungsten ore thiab mloog zoo

1. Qhia luv luv ntawm tungsten ore thiab mloog zoo

Tus nqi ntawm tungsten nyob rau hauv lub ntiaj teb crust yog me me. Raws li deb muaj 20 hom tungsten minerals pom, ntawm cov uas tsuas yog wolframite thiab scheelite tuaj yeem smelt. 80% ntawm lub ntiaj teb tungsten ore yog nyob rau hauv Tuam Tshoj, Russia, Canada, thiab Nyab Laj. Tuam Tshoj tuav 82% ntawm lub ntiaj teb tungsten.

Tuam Tshoj tungsten ore muaj qib qis thiab complex muaj pes tsawg leeg. 68.7% ntawm lawv yog scheelite, nws tus nqi qis thiab nws qhov zoo yog qis dua. 20.9% ntawm lawv yog wolframite, nws tus nqi zoo dua. 10.4% yog cov ore sib xyaw, suav nrog scheelite, wolframite, thiab lwm yam minerals. Nws nyuaj rau kev tawm mus. Tom qab ntau tshaj li ib puas ntawm kev nruam mining, high-zoo wolframite tau tas lawm, thiab qhov zoo ntawm scheelite tau qis dua. Nyob rau hauv xyoo tas los no, tus nqi ntawm tungsten ore thiab concentrate yog nce.

2. Ntau hom tungsten ore thiab mloog zoo

Wolframite thiab scheelite tuaj yeem ua rau hauv kev mloog zoo los ntawm kev sib tsoo, pob milling, sib cais lub ntiajteb txawj nqus, hluav taws xob sib cais, sib nqus sib nqus, thiab lwm yam txheej txheem. Lub ntsiab tseem ceeb ntawm tungsten concentrate yog tungsten trioxide.

Wolframite concentrate

Wolframite, tseem hu ua (Fe, Mn) WO4, yog xim av-dub, lossis dub. Wolframite concentrate qhia tau hais tias semi-metallic luster thiab belongs rau monoclinic system. Cov siv lead ua feem ntau tuab nrog longitudinal striations ntawm nws. Wolframite feem ntau yog symbiotic nrog quartz leeg. Raws li Tuam Tshoj tus qauv tungsten concentrate, wolframite concentrates tau muab faib ua wolframite tshwj xeeb-I-2, wolframite tshwj xeeb-I-1, wolframite qib I, wolframite qib II, thiab wolframite qib III.

Scheelite concentrate

Scheelite, tseem hu ua CaWO4, muaj txog 80% WO3, feem ntau grey-dawb, qee zaum me ntsis daj, lub teeb liab, lub teeb xim av, thiab lwm yam xim, uas qhia cov pob zeb diamond luster los yog roj luster. Nws yog tetragonal Crystal system. Daim ntawv siv lead ua feem ntau yog biconical, thiab cov aggregates feem ntau tsis sib xws granular lossis ntom blocks. Scheelite feem ntau symbiotic nrog molybdenite, galena, thiab sphalerite. Raws li kuv lub teb chaws tus qauv tungsten concentrate, scheelite concentrate tau muab faib ua scheelite-II-2 thiab scheelite-II-1.

3. Daim ntawv thov ntawm tungsten concentrate

Tungsten concentrate yog cov khoom siv tseem ceeb rau kev tsim khoom ntawm tag nrho cov khoom tungsten hauv cov khoom lag luam txuas ntxiv, thiab nws cov khoom siv ncaj qha yog cov khoom siv tseem ceeb rau tungsten tebchaw xws li ferrotungsten, sodium tungstate, ammonium para tungstate (APT), thiab ammonium metatungstate ( AMT). Tungsten concentrate tuaj yeem siv los tsim tungsten trioxide (xiav oxide, daj oxide, ntshav oxide), lwm yam khoom nruab nrab, thiab txawm tias pigments thiab tshuaj additives, thiab qhov txaus nyiam tshaj plaws yog qhov kev hloov pauv tsis tu ncua thiab kev sim ua ntej xws li violet tungsten hauv teb ntawm cov roj teeb lub zog tshiab.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
