摘要
A process for reducing the sodium chloride content of crystalline potassium salts without the use of successive recrystallization. The crystalline potassium salts having a sodium chloride content greater than about 0.8 percent by weight are subjected to compacting and crushing to provide a crystalline product having an average particle diameter less than 1.6 millimeters. The crystalline product is leached with a brine at least about 80 percent saturated with said potassium salt and less than 50 percent saturated with sodium chloride to produce a crystalline potassium salt product containing less than about 0.35 percent by weight of sodiumchloride.
