Claim 0:
1. A method for producing salt, the method comprising:
preparing hydrohalite particles by crystallization from saturated brine;
adding the hydrohalite particles to a salt brine, thereby forming a hydrohalite-salt brine mixture,
wherein an initial temperature of the salt brine prior to adding the hydrohalite particles is sufficient to decompose the hydrohalite particles without external heating;
wherein the initial temperature of the salt brine prior to adding the hydrohalite particles is between 0° C. and 40° C.; and
wherein a ratio of salt brine to hydrohalite particles, by weight, is from 0.4 to 29;

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.
