Methods for crystallizing soluble minerals from a brine stream are provided. Soluble minerals dissolved in a saturated brine stream can enter a crystallizer in liquid form and exit the crystallizer in crystal (solid) form. The crystallizer is able to do this by cooling the brine stream using atmospheric air.
