This invention refers to inorganic substances technology, in particular to the production of barium containing substances. Technical result of the invention is to produce high purity barium carbonate, to improve the process and to cheapen it. The essence of the invention is that as a barium containing compound is used barite concentrate having 15% SiO2 by contents, as a carbonate of alkali metal sodium carbonate; the leaching of baked charge is conducted by hot water, then the treatment of the obtained solution by carbon dioxide produced at baking of charge at the molar proportion BaSiO4:CO2 = 1 : 1,2.
