Abstract

Process for separating a mixture containing salt, into an ice slurry and a salt slurry, comprising the steps of feeding the mixture to a crystal lizer having a first output for the ice slurry and a second output for the salt slurry, treating the salt slurry, so that a liquid part is recycled to the crystallizer, the salt remaining, and washing the ice slurry on the belt filter, whereby purified ice is outputted from the belt filter, as well a liquid which can be recycled to the crystallizer.
