    Production methodprocess of Lanthanum oxide powder

    The raw material of extraction method is the rare earth nitrate solution after removing cerium, containing about LaO350%, CeO2 trace, Pr6O116%~7%, Nd2O330%. Formulated into ΣRxOy320 ~ 330g / L of nitric acid rare earth solution, the use of neutral phosphine extractant methylphosphonic acid dimethylheptyl ester (P350), P350 - paraffin system by 35 ~ 38 level of extraction and separation, so that the lanthanum and the separation of other rare earths, lanthanum-containing extracted residue by the ammonia and neutralisation, precipitation of oxalic acid, and then by filtration, burning, the production of Lanthanum oxide powder.
