Txuj ca
1. Tshuaj lom neeg sib cais qauv. Nws suav nrog kev ua haujlwm frystalry crystallization, factional nag lossis daus nag lossis oxidation. Cov qub yog sib cais raws li qhov sib txawv ntawm cov solestal solubility ntawm lub ntiaj teb tsis tshua muaj txiaj ntsig. Kev sib cais yog nyob ntawm cov khoom sib txawv los ntawm cov khoom lag luam tsis tshua muaj cua daj av ua av. Lub tom kawg yog sib cais raws li oxidation ntawm trunent pr3 + rau tetravalent pr4 +. Peb txoj kev no tsis tau thov kev lag luam vim lawv lub ntiaj teb qis qis, cov txheej txheem tsis txaus, cov txheej txheem nyuaj, cov txiaj ntsig nyuaj, thiab cov nqi siab.
2. Cais txoj kev sib cais. Suav nrog kev sib cais ua kom muaj kev sib cais thiab saponification p-507 extraction sib cais qauv. Lub qub siv complex extrusion DYPA thiab N-263 extractants mus rau extract thiab cais cov duab acidsmium ntawm cov pr6o11 99% tawm ntawm 98%. Txawm li cas los xij, vim muaj cov txheej txheem nyuaj, kev noj ntau ntawm cov neeg sawv cev sib luag, thiab cov nqi tsim khoom, nws tsis tau siv hauv kev lag luam ntau lawm. Lub tom kawg ob muaj extraction zoo thiab sib cais ntawm preaseymium nrog p-507, ob leeg uas tau thov hauv kev lag luam tsim khoom. Txawm li cas los xij, vim muaj kev ua haujlwm siab ntawm P-507 Extraction ntawm Preaseyodymium thiab kev poob siab thiab kev sib cais tam sim no yog cov siv tam sim no siv hauv kev lag luam ntau lawm.
3. Cov txheej txheem ion sib pauv tau tsis tshua siv hauv kev tsim khoom vim nws cov txheej txheem ntev, tab sis cov khoom lag luam tawm, tab sis cov khoom tawm ≥ 85%, thiab cov zis rau ib pawg ntawm cov cuab yeej yog tsawg.
1) Kev tsim cov preaseymium cov khoom siv txoj kev sib pauv khoom: Siv cov tswv yim preodymium neodymium enricks compounds (PR, ND) 2Cl3 raws li raw khoom. Nws tau npaj rau hauv kev daws kev noj (PR, ND) CL3 thiab thauj mus rau sab adsorption kem rau Adsorb saturated tsis tshua muaj ntiaj teb. Thaum cov concentration ntawm cov tshuaj uas tuaj yeem yog tib yam li cov outflow concentration, adsorption ntawm cov av tsis tshua muaj thiab tos rau cov txheej txheem tom ntej los siv. Tom qab thauj cov kem rau hauv Cationic Resin, Cuso4-H2So4 Kev daws teeb meem yog siv los ntws mus rau CU H + tsawg lub ntiaj teb sib cais sab rau siv. Tom qab sib txuas ib kab lus adsorption thiab peb kab sib cais hauv series, siv Edt A (015M) ntws los ntawm thawj cov inlet ntawm thawj kab lus Qhov thib peb kem sib cais thaum muaj kev sib cais, nws tuaj yeem sau los ntawm cov ntawv sib cais yog cais, ntshiab li ntawm cov kab sib cais los ntawm qhov sib cais ntawm cov kab sib cais thiab raug tshuaj lom neeg Txhawm rau tsim PR6o11 khoom. Cov txheej txheem tseem ceeb yog li hauv qab no → kev sib cais ntawm cov kev sib cais ntawm cov kab sib cais →
2) Zus tau cov khoom siv preaseymium oxide cov khoom siv P-204 extraction Cerium: Siv Lanthhanum Cartium Praseodide (LA, PR) CL3 raws li cov khoom siv raw. Sib tov cov khoom nyoos rau hauv cov kua, siponify p-204, thiab ntxiv rau kerosene los ua cov kev daws teeb meem. Cais cov pub ua kua los ntawm cov rho tawm preaseyodymium nyob rau hauv cov kev piav qhia meej clipification tank. Tom qab ntawd ntxuav cov impurities nyob rau hauv cov organic theem, thiab siv HCL los rho cov nuj nqi preasemium kom tau txais cov Prcl3 tov. Precipionate nrog oxalic acid, calcine, thiab pob kom tau cov preaseymium oxide khoom.
