ABSTRACT:
An improved process for producing stable, high purity alkali metal or alkaline earth metal ferrate salt products is disclosed. In this process, crude ferrate salts, after being precipitated and separated from a chilled mother liquor, are purified first with a chilled anhydrous, water miscible extraction solvent to remove residual process contaminants therefrom followed by chilled oxidation resistant rinse solvent step, miscible with said extractant, followed by a drying step so as to produce a stable, purified ferrate product which can be safely stored without special provisions. Both batch and continuous modes of operation are disclosed.
