METHOD OF PRODUCING AGGLOMERATED POTASSIUM CHLORIDE Russian patent published in 2015 - IPC C01D3/08 C01D3/24 

FIELD: chemistry.

SUBSTANCE: invention can be used in chemical industry. A method of producing agglomerated potassium chloride includes mixing a liquid and a solid phase to form a suspension which is heated to boiling point. Said temperature is maintained for 12-15 minutes while stirring the suspension. During heating and ageing, the suspension is treated with jet steam. Further, the suspension is cooled at a rate of (2-3)°C per minute. The crystalline agglomerated potassium chloride is separated from the liquid phase and dried. The solid phase used in the suspension is cyclone dust of floatation potassium chloride and the liquid phase is aqueous potassium chloride with 80-100% saturation. The liquid to solid ratio is kept in the range of 2-3.

EFFECT: invention increases output of agglomerated potassium chloride with average particle size of 0,4-0,7 mm.
