Tam sim no lub peev xwm tsim khoom hauv tsev ntawm potash thiab oxides yog ntau dua li qhov xav tau ntawm kev ua lag luam, thiab cov khoom muaj peev xwm ntawm cov khoom siv rov qab-kawg cov khoom muaj nqis ntxiv kuj tseem ceeb heev, tab sis cov khoom tsim tawm ntawm cov ore yog tsawg heev, thiab cov peev txheej ntawm kev ua haujlwm siab. cov khoom muaj nqis ntxiv yog piv rau cov neeg txawv teb chaws. Qhov no txhais tau hais tias ntau qhov chaw tsim khoom thiab kev lag luam hauv Tuam Tshoj txoj kev lag luam tantalum thiab niobium tsuas tuaj yeem zom cov peev txheej ntau dhau los ntawm kev xa cov ore thiab xa tawm cov khoom lag luam nruab nrab, uas ua rau cov txiaj ntsig qis thiab muaj kev pheej hmoo siab.

Ua ntej kawg ntawm xyoo 2011, kev lag luam tantalum thiab niobium tau ua haujlwm ib txwm nyob hauv ib puag ncig zoo. Muaj ntau chav rau kev tsim cov tantalum thiab niobium nyob rau pem hauv ntej kawg. Qhov nruab nrab hydrometallurgy thiab pyrometallurgy kuj muaj qee yam txiaj ntsig, thiab tom qab kawg muaj qhov tshwj xeeb ntim ntawm tantalum hmoov. , Tantalum hlau tsim thiab kev muag khoom lag luam kuj muaj ntau chav rau kev ua haujlwm, tab sis txij li ib nrab xyoo 2012, nrog qhov tshwm sim ntawm kev kub ntxhov thoob ntiaj teb, daim ntawv thov ntawm tantalum thiab niobium yog qhov nqaim, thiab kev noj zaub mov feem ntau yog siab. -end khoom siv hluav taws xob. Kev lag luam tau cuam tshuam zoo heev, thiab qhov tshwj xeeb ntawm ob qhov kawg ntawm Tuam Tshoj txoj kev lag luam tantalum thiab niobium (raws li cov khoom siv sab nraud, kev lag luam sab nraud) yog nyob rau hauv kev lag luam ntau dua.
Txij li thaum Lub Kaum Hli 2012, tus nqi ntawm tantalum ore nyob rau hauv Suav lag luam tau poob txhua txoj kev. Tus nqi muag tam sim no tau tshaj li tus nqi tsim khoom ntawm cov mines hauv tsev. Txawm tias African tantalum ore, uas tau muag los ntawm tus nqi qis, kuj tau hnov lub khw. Nyob rau hauv lub siab ntawm kev poob qis, kev xa khoom poob qis heev. Nyob rau tib lub sijhawm, vim qhov tsis muaj zog ntawm kev lag luam davhlau ya nyob twg rau tantalum ore noj, cov khoom tiav muag kev lag luam ntawm tantalum thiab niobium ntau lawm saw yog sluggish, ua rau cov neeg siv txawv teb chaws siv ob lub xauv (xauv tus nqi muag thiab xauv tus nqi. ntawm cov khoom siv raw) los npaj cov khoom siv rau kev tsim khoom thiab ua kom tag nrho cov khoom siv raw. , Nyob rau hauv lub hauv paus ntawm cov nyiaj tau los nyob rau hauv nruab nrab-kawg kev sib txuas, kev ua haujlwm ib txwm muaj ntawm cov saw hlau muaj kev tswj xyuas. Hauv Suav teb av loj, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau kos npe thiab yuav khoom ua ntej xyoo 2012, Ningxia Dongfang Tantalum Kev Lag Luam, lub tuam txhab teev npe, tau yuav cov khoom siv raw thiab txo tus nqi ntawm kev yuav khoom los ntawm kev ncaj qha nrog cov neeg muag khoom African tantalum ore rau peb lub xyoos dhau los. . , kev yuav khoom ntawm tantalum ore, oxides, thiab potash tau pib nres, thiab cov chaw ua haujlwm hauv tsev tantalum thiab niobium feem ntau siv cov khoom siv txawv teb chaws, kev pab hauv tsev, thiab ob lub xauv los yuav cov ore, thiab npaj ntau lawm tom qab tau txais kev txiav txim. Cov khoom muag, ua rau tam sim no qis muag chav tsev nqi ntawm tantalum thiab niobium concentrate, muag ntim tsis loj. Ntawm tag nrho, cov khoom siv tam sim no thiab kev xav tau hauv kev lag luam tantalum thiab niobium yog qeeb, tus nqi siab, tus nqi muag qis, thiab kev ua haujlwm tsis zoo. Raws li kev txheeb cais ntawm Tantalum thiab Niobium ceg ntawm Tuam Tshoj Nonferrous Metals Association thaum kawg ntawm 2014, nws tuaj yeem pom tias txawm hais tias kuv lub teb chaws muaj peev xwm ua tau txaus, vim tsis muaj cov khoom tsim los ntawm tus kheej thiab tsis muaj peev xwm ua tau zoo ntawm cov khoom lag luam. davhlau ya nyob twg, ntau tantalum thiab niobium ua lag luam tsis muaj peev xwm ua tau nyob rau hauv 2014. Tag nrho cov khoom. Hauv xyoo 2014, Suav tantalum thiab niobium cov tuam txhab tsim tawm tag nrho ntawm 112 tons ntawm tantalum ore (Ta 2 O 5), 458 tons ntawm poov tshuaj ntsev, 262 tons ntawm high-purity tantalum oxide, tantalum hlau (tantalum bars, tantalum khoom, capacitor tantalum. hmoov, metallurgical qib Tantalum hmoov, tantalum hlau) 575 tons, tantalum carbide 55 tons. Qhov sib txawv ntawm qhov muaj peev xwm ntau lawm thiab cov khoom tso tawm tiag tiag yog qhov zoo heev, tab sis nrog cov khoom siv zoo li no, txhua lub koom haum ua haujlwm tseem muaj qee yam ntawm cov khoom muag, thiab muaj qhov pom tseeb ntawm qhov khoom siv ntau dhau.
