<p>A method and an apparatus for crystallizing a mineral substance in a fluidized bed of crystals (14) generated by circulating a supersaturated solution of the substance to be crystallized upwards through a fluidized bed reactor distributor (12) located under the bed (14), whereafter a fraction (22) of the supersaturated solution is drawn off upstream from the distributor (12) and recycled downstream therefrom in the fluidized bed (14) or the mother liquor of crystallization, and said mother liquor is supersaturated to recreate the above-mentioned supersaturated solution.</p> |
