Abstract:
A process for forming a mineral, food or pharmaceutical grade salt product, said process comprising the steps of:(a) loading or providing reactants in a reactor vessel; (b) with optional mixing, adjusting the temperature of the reactants to a first set point temperature in said reactor vessel, wherein the first set point temperature is above about 25Â° C. when operating said process at about 1 atmosphere pressure; (c) with optional mixing, adding a fluid to the reactants of step (b) in an amount sufficient to initiate reaction of all or nearly all of the reactants to form a first mixture; and (d) with optional mixing, adjusting the temperature of the first mixture to a second set point temperature, when operating said process at about 1 atmosphere pressure, of at least 190Â° F. for a time sufficient to evaporate substantially all of the fluid to yield said mineral, food or pharmaceutical grade salt product having a moisture content of less than about 6%, wherein said steps (a)-(d) are completed in said reactor vessel.
