Tom qab ntau tshaj 40 xyoo ntawm kev siv zog, tshwj xeeb tshaj yog kev loj hlob sai txij li xyoo 1978, Tuam Tshoj tustsawg ntiaj tebkev lag luam tau undergone ib tug zoo leap nyob rau hauv ntau lawm theem thiab cov khoom zoo, tsim ib tug ua tiav industrial system.Tam sim no,tsawg ntiaj tebrefining nyob rau hauv Suav teb
Cov ore smelting thiab sib cais muaj peev xwm ncav cuag ntau tshaj 130000 tons hauv ib xyoos (REO), thiab cov khoom tsim txhua xyoo ntawm lub ntiaj teb tsis tshua muaj txog 70000 tons, suav txog ntau dua 80% ntawm lub ntiaj teb tag nrho cov khoom.Nws ntau lawm thiab export ntim yog ob qho tib si lub ntiaj teb coob.
Muaj ntau tshaj 170tsawg ntiaj tebsmelting thiab cais cov lag luam hauv Suav teb, tab sis tsuas yog 5 muaj peev xwm ua txhua xyoo ntau dua 5000 tons (REO), nrog rau cov lag luam feem ntau muaj peev xwm ua tau ntawm 1000-2000 tons.
Tam sim no, Tuam Tshoj tau tsim peb lub hauv paus loj tshaj plaws nyob ib ncig ntawm peb qhov lojtsawg ntiaj tebcov peev txheej:
(1) Ib sab qaum tebtsawg ntiaj tebntau lawm puag tau tsim nrog Baotou tovtsawg ntiaj tebore li raw khoom, nrog BaotouLub ntiaj teb tsis tshua muajHigh Tech thiab Gansu Rare Earth Company ua lub pob txha.Muaj ntau tshaj 80 lub tuam txhab tsim khoomtsawg ntiaj tebtshuaj xws litsawg ntiaj teb chloridethiab carbonate txhua xyoo
Ntau tshaj 60000 tons ntawm cov tebchaw thiab 15000 tons ntawm ib leegtsawg ntiaj tebtshuaj sib xyaw.Tam sim no, feem ntautsawg ntiaj tebkev lag luam ua Baotou ore siv cov kua qaub smelting txheej txheem tsim los ntawm Beijing Nonferrous Metals Research Institute, thiab tom qab ntawd siv P204 los yog P507 extraction skev sib cais, uashigh-purity ceriumFeem ntau yog muab rho tawm los ntawm oxidation extraction, thiab qib fluorescenteuropium oxideyog muab rho tawm los ntawm kev txo extraction.Cov khoom tseem ceeb muaj xws li ib leeg lossis sib xyaw tsis tshua muaj lub ntiaj teb sib txuas xws lilanthanum, cerium, praseodymium, neodymium, samarium, europium, lwm.
(2) Qhov nruab nrab thiab hnyavtsawg ntiaj tebntau lawm puag yuav siv cov ionic yav qab teb hom ores li raw cov ntaub ntawv, thiab lis ze li ntawm 20000 tons ntawm yav qab teb hom ionictsawg ntiaj tebore txhua xyoo.Cov lag luam txha caj qaum suav nrog Guanzhou lub Pearl River Smelter, Jianyin JiahuaLub ntiaj teb tsis tshua muajFactory, thiab Yixin Xinwei Rare Earth Co., Ltd Tuam txhab, Liyan Luodiya Fangzheng Rare Earth Company, Guangdong Yanjiang Rare Earth Factory, thiab lwm yam. Southern ion hom tsawg ntiaj teb mines feem ntau siv ammonium sulfate nyob rau hauv situ leaching carbonate nag lossis daus ignition hydrochloric acid dissolution P507 thiab naphnicthe. acid extraction sib cais thiab purification.
Nruab nrab mus rau hnyav ib leegtsawg ntiaj teb oxidesthiab ib co enriched compounds xws liyttrium, dysprosium, terbium, europium, lanthanum, neodymium, samarium, lwm.
(3) Siv Mianning fluorocarbon cerium ore nyob rau hauv Sichuan raws li raw khoom, lub hauv paus tsim rau fluorocarbon cerium ore tau tsim nyob rau hauv Sichuan.Tam sim no muaj 27 hydrometallurgy nroj tsuag nrog tag nrho cov khoom txhua xyoo ntawm 15-2000 tons.Cov txheej txheem smelting ntawm fluoride ore thiabceriumore feem ntau yog oxidation roasting various chemical kev kho cov txheej txheem muab tau los ntawm cov txheej txheem tseem ceeb ntawm roasting sulfuric acid leaching, nrog rau cov khoom yog ib qho los yog sib tov tsis tshua muaj ntiaj teb tebchaw feem ntau yog tsim los ntawmlanthanum, cerium, thiabneodymium.Feem ntau cov tuam txhab lag luam me me, nrog cov cuab yeej siv qis thiab thev naus laus zis.Tntawm no yog ntau yam khoom tseem ceeb hauvtsawg ntiaj tebsmelting khoom, nrog siab purity thiab ib tug tsawg tsawg lub ntiaj teb compound khoom kwv yees tsis pub tshaj 5%.
