FIELD: chemistry. ^ SUBSTANCE: invention can be used in producing halurgic potassium chloride from sylvinite ore using a dissolution-crystallisation method. The method of producing potassium chloride involves structural agglomeration of a mixture of a wet crystallisate and dry hot potassium chloride in a mixer-granulator and then drying the mixture. For structural agglomeration of the mixture, dry hot potassium chloride is fed in amount of 25-100% of the weight of wet crystallisate. The mixture is dried at temperature 105-135C to obtain the end product. ^ EFFECT: invention reduces caking capacity of potassium chloride, avoids use of structure-forming salts, reduces consumption of reagents used to prevent potassium chloride from caking, and obtain a product which does not contain extraneous impurities. ^ 2 cl, 2 tbl, 2 ex |
