Patent
·
OSTI ID:1840349
A method is provided for separating and/or purifying different metal oxalates by mixing the different metal oxalates in an aqueous solution comprising oxalic acid and an organic base so that at least one metal oxalate is soluble and at least another metal oxalate is not soluble. Different rare earth metal oxalates and/or transition metal oxalates can be separated.
