Process is carried out in beaded mill of vertical type fitted with reflux cooling-condenser, high-speed blade mixer and glass beads as grinding agent loaded in the mass ratio to liquid phase = 1.5:1. Liquid phase represents glacial acid solution in ethylcellosolve, ethylene glycol, 1,4-dioxane, isoamyl alcohol and n-butyl alcohol as a solvent. The concentration of acid in liquid phase is 3.4-4 mole/kg. Then method involves loading iodine in the amount 0.025-0.070 mole/kg of liquid phase, metallic manganese and manganese dioxide in the mole ratio = 2:1 and taken in the amount 11.8% of liquid phase mass. The process starts at room temperature and carries out under self-heating condition to 30-38°C to practically complete consumption of manganese dioxide. Prepared salt suspension is separated from beads and unreacted manganese and filtered off. Filtrate is recovered to the repeated process and prepared precipitate is purified by recrystallization. Invention provides simplifying method using available raw and in low waste of the process.
