A preliminary assessment of the available options to recover soluble salts from salt-cake slag material has been carried out. From limited benchscale experiments, it was demonstrated that in a semicontinuous batchmode operation, about 85% of the chlorides in a one-stage or close to 100% in a multistage series of exhaustion operations can be converted to bicarbonates through an ion-exchange, resin-based option.
