Study of Purity Improvement of Rare Earth Oxide in South Ore Deposit AITranslate
Abstract AITranslate
The technology for purity improvement of composite RE oxides in south ore deposits is studied. Raw material is leached by a selected strong-acid ammonium salt at a control led PH and with addition of ammonium sulfide as purification reagent. Leached solution is pretreatmented with reagent at a proper PH. Pretreatmented solution is subjected to double precipitation first with ammonium bicarbonate and then with oxalic acid to obtain pure RE. Precipitating ratio, PH and amount of ammonium sulfate are important factors to RE purity. Aforesaid method is useful to various solutions.
