Extraction ntawm Scandium oxide los ntawm Tungsten Slag

Peb lub teb chaws muaj nplua nuj nyob hauv cov khoom siv hlau uas tsis muaj hlau, tshwj xeeb tshaj yog cov khoom siv tungsten. Cov peev txheej thiab cov tsuas ntim ntawmlub tungstenee qeb ua ntej nyob hauv lub ntiaj teb. Tuam Tshoj The Tungsten Cov Nyiaj Tseg rau kwv yees li 47% ntawm lub ntiaj teb cov peev txheej, thiab nws cov peev txheej muaj txiaj ntsig rau 51% ntawm lub ntiaj teb no tungsten kev lag luam cov kev lag luam. Tuam Tshoj lub tungsten cov khoom siv yog hais kom muaj tseeb, nrog cov peev xwm hauv Jiangxi thiab Hunan Provinces account rau ntau tshaj 54% ntawm lub teb chaws cov peev txheej. Kev txhim kho ntawm Tuam Tshoj lub Tungsten cov kev pab tau pom hauv HuasHan, YUXGI, Jiangxi xeev hauv xyoo 1907. Tsuas pib xyoo 1908 thiab muaj keeb kwm muaj ib puas xyoo. Kwv yees li 80% ntawm cov kev khaws tshwj tseg, thiab kev siv nyiaj ntawm Wolframite tau tshaj li 90%, scheelite tau tshaj 75%, thiab ntau cov peev txheej qub yog sab sab. Yog tias tsis muaj qhov kev nce qib tshiab nyob ze rau yav tom ntej, kuv lub teb chaws Tungsten cov peev txheej yuav maj mam ua haujlwm. Tsis tsuas yog tungsten cov peev txheej yog zoo li qhov no, tab sis lwm cov khoom tsis muaj hlau kuj tseem ntsib teeb meem tib yam.

Cov seem tau tom qab rho tawmlub tungstenLos ntawm tungten mloog los ntawm alkali leaching feem ntau hu ua tungsten slag. Tom qab kaum xyoo ntawm kev tsim khoom, kev txuam nrog ntau dua ib lab tons yam tsis muaj kev kho, thiab tshiab tungsten slag yog tsim txhua txhua xyoo. Cov slags no tsis tsuas yog muab ib lub nra hnyav rau ib puag ncig, tab sis kuj pov tseg lub teb chaws tsis muaj peev xwm ua tau ntau yam. Vim tias tungsten slag muaj lwm yam tshaj tungsten. Nws tseem muaj cov khoom muaj nuj nqis xws li hlau, manganese, tin,scandium,tantalum, thiabniobiumCov. Nws yog ib qho kev nplua nuj uas tsis muaj ferrous. Niaj hnub no, thaum cov ntxhia cov khoom siv tau nce qib ntxiv, tshwj xeeb yog cov nqi hlau tsis muaj nqi, nws tsis tshua pom tau nws hauv ntau xyoo. Nyob rau lub sijhawm no, yuav ua li cas nkag siab siv tungsten slag kom rov tsim kho cov pa paug, thiab tib lub sijhawm txo qis kev sib tw, muaj kev nce qib ib puag ncig, muaj kev txom nyem ntau heev thiab cov tswv yim tseem ceeb.Qhov project pom tau tias cov kev pab ua kom zoo ntawm tungsten slag thiab tiav "xoom khib nyiab". Nws tsis tsuas yog rov txiav txim siab tungsten thiabscandium, tab sis kuj tseem rov qab qhia ntau npaum li cas ntawm cov hlau thiab manganese. Nws kuj tseem tau txais kev txhawb nqa xws li tin,tantalum, thiabniobium, uas muab lwm tus kev lag luam muab cov khoom siv roos kom tsis muaj cov khoom siv hlau uas tsis yog cov khoom siv hlau tuaj yeem hloov kho tau zoo dua. Nyob rau tib lub sijhawm, nws txhawb nqa daim ntawv thov ntawm scandium thiab muab ib tug muaj zog rov qab rau kev txhim kho ntawm scandium cov khoom. Txoj kev kho huv siab ntawm Tungsten Slag daws cov kev ua kom ib puag ncig los ntawm kev sib txuam ntawm cov roj tungsten swb yam tsis muaj kev ua qias tuaj. Nws yog qhov kev rov ua dua tshiab thiab muaj qhov tseem ceeb tshaj plaws uas ua rau kuv lub teb chaws txoj kev loj hlob.
