A method for the treatment of hardly soluble potash-magnesium ore comprises decomposition of ore, washed from chloride minerals, in solution of acid, filtering of insoluble residue and treatment of solution by reagent with the obtaining of fertilizer with the further filtering and drying. Besides as acid phosphate acid is used, as reagent - aqueous solution of ammonia, after the treatment of the solution by reagent hexahydrate of ammonium-magnesium phosphate is filtered out, and the fertilizer is obtained by evaporation of the filtered out solution with further cooling.
