Tom qab ntau tshaj 40 xyoo ntawm kev siv zog, tshwj xeeb tshaj yog kev loj hlob sai txij li xyoo 1978, Suav tebTsis tshua muaj ntiaj tebKev lag luam tau undergone ib tug tsim nyog leap Tam sim no,Tsis tshua muaj ntiaj tebRefining hauv Suav
Lub ore smelting thiab sib cais muaj peev xwm ncav tau tshaj 130000 tons ib xyoos (RO), thiab lub xyoo txhua xyoo, suav rau ntau tshaj li 80% ntawm lub ntiaj teb tag nrho cov khoom lag luam. Nws cov khoom lag luam ntau lawm thiab xa tawm yog ob lub ntiaj teb loj tshaj plaws.
Muaj ntau tshaj 170Tsis tshua muaj ntiaj tebSMELTING THIAB SIB TXHAWB HAUV CHINAIN, tab sis tsuas yog 5 muaj lub peev xwm txhua xyoo ntau dua 5000 tons (Ro), nrog feem ntau cov lag luam muaj peev xwm ua tau muaj peev xwm ntawm 1000-2000 tons.
Tam sim no, Tuam Tshoj tau tsim peb lub hauv paus loj loj feem ntau yog nyob ib puag ncig pebTsis tshua muaj ntiaj tebCov Khoom Siv:
(1) ib sab qaum tebTsis tshua muaj ntiaj tebntau lawm tau tsim nrog baotou sib xyawTsis tshua muaj ntiaj tebore raws li cov khoom siv raw, nrog baotouTsis tshua muaj ntiaj tebHigh tech thiab gansu tsis tshua muaj lub ntiaj teb lub tuam txhab ua tus caj qaum. Muaj ntau dua 80 tus neeg lag luam uas tsimTsis tshua muaj ntiaj tebtshuaj lom xws liHauv ntiaj teb tsawg tshuaj chloridethiab carbonate txhua xyoo
Ntau tshaj 60000 tons ntawm cov tebchaw thiab 15000 tons ntawm ib leegTsis tshua muaj ntiaj tebtebchaw. Tam sim no, feem ntauTsis tshua muaj ntiaj tebKev Lag Luam Ua Si Baotou ore Siv cov acid SMORTING txheej txheem tsim los ntawm Beijing Cov Hlau Kev Tshawb Fawb Cov Hlau, thiab tom qab ntawd siv P204 lossis P507 Extraction SEparation, ntawm uasHigh-purity ceriumFeem ntau muab rho tawm los ntawm oxidation extraction, thiab fluorescent qibEuropium oxideyog muab rho tawm los ntawm kev txo qis. Cov khoom tseem ceeb muaj ib qho lossis sib xyaw hauv ntiaj teb tsawg dua xws lilus qhia, xiIAB, Preaseymium, neodymium, samar, huab cua, thiab lwm yam.
(2) qhov nruab nrab thiab hnyavTsis tshua muaj ntiaj tebNtau lawm puag ncig yuav siv sijhawm noj lus qab teb ionic ores ua cov khoom nyoos, thiab cov ntaub pua chaw ze 20000 ntawm hom khoom ionicTsis tshua muaj ntiaj tebores txhua xyoo. Tus kabmob caj qaum suav nrog Guanzhou cov hlaws dej smelter, Jianyin JiahuaTsis tshua muaj ntiaj tebHoobkas, thiab yixin Xinwei Tsawg Lub Ntiaj Teb Co., Likoj Sullzheng Tsis Muaj Kub Lub Ntiaj Teb, thiab lwm yam. Acid extraction sib cais thiab ua kom huv.
Nruab nrab rau hnyavTsis tshua muaj lub ntiaj teb oxidesthiab qee qhov sib txuas ntxiv xws liyttrium, dysprosium, terbium, huab cua, lus qhia, neodymium, samar, thiab lwm yam.
(3) Siv Mianning Fluorocarbon calefium gluium ore hauv Sichuan yog cov khoom siv raw, ib qho kev tsim khoom rau cov roj fluorocarbon cerium tau tsim hauv Sichuan. Tam sim no muaj ntau cov nroj tsuag hydrometallurgurgurgurgurgurgurgurgy nrog tag nrho cov zis txhua xyoo ntawm 15-2000 tons. Cov txheej txheem smelting ntawm fluoride ore thiabxiIABORE tsuas yog suav nrog oxidation ci vCov txheej txheem muaj tshuaj lom neeg tau muab los ntawm cov txheej txheem tseem ceeb ntawm cov txheej txheem ci ntsa iab sulfuric acid leaching, nrog cov khoom lag luam tsis tshua muaj neeg lossis sib xyaw ntawmlus qhia, xiIAB, thiabneodymiumCov. Feem ntau cov lag luam feem ntau yog me me hauv nplai, nrog cov khoom siv tsawg thiab qib thev naus laus zis.tNov yog ntau yam khoom lag luam tseem ceeb hauvTsis tshua muaj ntiaj tebSmelting khoom, nrog tib lub siab thiab ib nrab ntawm lub ntiaj teb cov khoom lag luam kwv yees kom tsis tshaj 5%.
