PROCESS FOR PREPARING NON-DUSTING POTASSIUM FERTILIZER Russian patent published in 1994 - IPC

Abstract RU 2019535 C1

FIELD: preparation of non-dusting mineral fertilizers. SUBSTANCE: the process for preparing a non-dusting potassium fertilizer comprises treating potassium chloride with an organic additive. The additive is glycerol tar in an amount of 0.02-0.3% by weight of the fertilizer. The content of duct-like fractions in potassium chloride is reduced from 73.1 to 38.4-6 mg/kg, i. e. by 1.9-12.2 times. EFFECT: improved properties of the potassium fertilizer. 1 tbl
