New Technology of Pruducing Refined Salt by Adding Salt Field Saturated Brine into Evaporating Pot Directly

NaCl was produced by adding salt field saturated brine into evaporating pot to evaporate and crystallize.In this process,Ca~(2+) and Mg~(2+) was removed by washing three times,and the aim is to obtain NaCl that its pureness was more than 99.1% and mother liquor with the quite high concentration for producing salt.
