Реферат: Disclosed herein is a method for producing iron (II) oxalate from an insoluble iron material, the method comprising digesting the insoluble iron material with a digestion liquor comprising one or more acids, and reacting digested iron species with a source of oxalate, the oxalate being in stoichiometric excess relative to the digested iron species, to form a slurry comprising iron (II) oxalate and residual oxalate; separating the iron (II) oxalate from the slurry to provide a solids stream comprising the iron (II) oxalate and a liquids stream comprising residual oxalate; and recycling the liquids stream as the source of oxalate or a component thereof.
