This invention refers to inorganic chemistry, in particular to methods for production of manganese (II) hydroarsenate. Technical result of the invention is to simplify the technological process, to reduce manufacturing cost of the final product and to improve environments. The method comprises interaction of manganese dioxide and production wastes of trichlorarsenic by heating, after which the reaction mixture is filtered and the filtrate is treated by ammonia hydroxide. The obtained final product in the form of sediment is filtered, washed and dried, whereas the production wastes of trichloricarsenic has the proportion of arsenic chloride and hydrogen tetrachlorarsenate (III) of 1:3. 1 Tabl.
