황산암모늄 열 분해에 의한 폐 알칼리전지 중의 Mn 성분의 추출
The Extraction of Manganese in the Spent Alkaline Batteries by the Thermal Decomposition of Ammonium Sulfate
A reaction between the solid electrolyte in the spent alkaline batteries and (NH4)2SO4 was carried out to find a new process for the extraction of Mn component from the spent alkaline batteries. The maximum extraction, 97.1%, was achieved when the reaction temperature was 400 ℃, the weight ratio of (NH4)2SO4 to the solid electrolyte in the spent alkaline batteries was 16.0 and the reaction time was 180 minutes.
