| titleOfInvention | METHOD FOR PRODUCING MANGANESE SULPHATE |
| abstract | Process for the preparation of manganese sulfate, which comprises the following steps: A adding sulfide having reducing ability to manganese dioxides by quantification according to the molar ratio of the reaction, stirring at 40-85 ° C for the complete reaction, determining the end point of the reaction and then separating and washing the solid product; B Reacting the solid product with 9-12 mol / l H 2 SO 4 , the reaction conditions being normal pressure and normal temperature, controlling the end point of the reaction as pH 3-5, controlling the feed amount according to the MnO content to maintain the MnSO 4 concentration in the reaction liquid within the range of 300 ~ 400 g / L, and then perform solid-liquid separation after completion of the reaction; C. Acidify the solution resulting from the solid-liquid separation with H 2 SO 4 until the pH of the solution is 2-3, add hydrogen peroxide and heat, finely filter the mixture to remove the solid phase, and then evaporate, Condensing and crystallizing the filtrate and dewatering the resulting crystalline material to ... |
