摘要： The invention relates to an evaporative crystallization process to make salt compositions that includes a step wherein a mother liquor is formed that contains an effective amount of a crystal growth inhibitor that is selected from oligopeptides, polypeptides, and polymers bearing two or more carboxylic acid groups or carboxyalkyl groups and optionally further phosphate, phosphonate, phosphino, sulfate, and/or sulfonate groups, such as carboxymethyl cellulose with phosphate groups, to form salt crystals with a (111) face. The salt can be washed with a reduced amount of washing water while still containing lower amounts of K, Br, SO 4 , and/or Ca. A wet salt can be obtained by partially drying the salt crystal that are formed.

摘要： The invention relates to an evaporative crystallisation process to make salt compositions which includes a step wherein a mother liquor containing an effective amount of a crystal growth comprising at least one saccharide or saccharide derivative is formed, to form high-purity salt. The salt can be washed with a reduced amount of washing water while still containing lower amounts of K, Br, SO 4 and/or Ca. The high-purity salt can be obtained after drying of the salt crystals formed. A wet salt can be obtained by partially drying said salt crystals.
