Abstract
Salt production can include preparing hydrohalite particles by crystallization from saturated brine, adding the hydrohalite particles to a salt brine, thereby forming a hydrohalite-salt brine mixture, agitating the hydrohalite-salt brine mixture until the hydrohalite particles have decomposed into NaCl crystals, and filtering out the NaCl crystals from the salt brine. In some instances, an initial temperature of the salt brine prior to adding the hydrohalite particles is at least 0° C. In some instances, a ratio of salt brine to hydrohalite particles, by weight, is from 0.4 to 29.
