The invention discloses a method for producing a manganese electrolyte by using continuous countercurrent leaching, the method comprises the following steps: the qualified manganese mine powder or a manganese mine slurry is mixed with inorganic acid in a neutral reaction device, a mixed liquor treated through a neutral leaching reaction is performed a solid-liquid separating process, a supernatant is obtained for an oxidizing treatment and an vulcanizing treatment; leaching slag is obtained by filtering and performed an acidic leaching, the mixed liquor in an acidic leaching device is filtered, the filtered acidic supernatant is taken as an anolyte and added in the neutral leaching apparatus for circularly using; an obtained electrolytic qualified liquid is filtered after a vulcanizing reaction. The invention has the advantages of high utilization rate of equipment, low investment, less energy consumption, high metal leaching rate and easy realization of mechanization and automation; and is capable of improving the recovery rate of manganese.
