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, SO4 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.
