Abstract
A process for the separation of a mineral acid from a common ion salt comprises a step of flowing a quantity of the mineral acid and salt in aqueous solution onto a strong base common ion form anion exchange resin bed whereon the mineral acid is retarded with respect to the salt. The salt is removed from the anion exchange resin. An interface cut of the mineral acid and the salt is recirculated from a bottom portion to a top portion of the anion exchange resin for further separation. A quantity of water is flowed through the anion exchange resin bed to elute the mineral acid therefrom. A portion of the elutant fluid is recycled to the top of the anion exchange resin bed.
