This invention refers to chemical technology of manganese, in particular to method for treatment of manganese ore. This invention ensures the increase in manganese nitrite purification degree. According to the invention there is provided method comprising nitrite leaching in the presence of ammonium sulphate, bringing up the pulp to pH 3-4 by introducing ammonia, filtering under room temperature by anionite AB-17 during passing the solution with the speed of 0,15-0,2 mm and precipitation from manganese solution in the from of carbonate by conversion gaseous CO2 and NH3.
