Abstract
Crystals are grown in a column through which a supersaturated solution flows upwardly while large crystals having one dimension substantially greater than another dimension taken from the bottom of the column are fractured externally of the column and the fractured particles are returned to the upper end of the column where fines are separated from larger seed type particles.
