Abstract

Method of obtaining an essentially pure iron salt from acidic, metal contaminated water (1) comprising Fe<2+>, in which: a) said contaminated water is brought to pass through a cationactive ion-exchange compound of a type A, which is selective to Fe<3+>, b) the water from step a is treated with one or more oxidising agents, so that Fe<2+> present in the water is oxidised to Fe<3+>, c) the water from step b, now comprising Fe<3+>, is brought to pass through an ion-exchange compound of the same type, type A, as the ion-exchange compound in step a, d) the ion-exchange compound in step c is regenerated, a solution of said essentially pure iron salt being obtained.
