The article presents the processes of obtaining magnesium (lime ammonium nitrate) LAN based on the granulation of dolomite-sulfatenitrate liquids obtained by adding DM and (NH4)2SO4 to AN liquid, as well as studying the composition and physico-chemical properties of ready-made fertilizers. It was found that, based on the determination of the physical and mechanical properties of various mine dolomite minerals, their suitability for use as a modifier for saltpetre was proven. The addition of dolomite mineral from 100:3 to 100:45 weight ratio and (NH4)2SO4 in the amount of 3 to 10% of the total mass of dolomite-nitrate mixture to the AS fluid increases the strength of OAN grains by 2-8 times and viscosity by 2-4 times was found to decrease. It was found that in the presence of DM and (NH4)2SO4, the decomposition temperature of ammonium sulfate (AS) increased from 211°C to 262.7°C. By adding dolomite mineral (DM) and (NH4)2SO4 to Ammonium nitrate (AN) liquid, technologies for obtaining complex fertilizers with good physicochemical and commercial properties, with a content of not less than 34% and not more than 28% for export, were developed.
