| titleOfInvention | Method for preparing electrolytic manganese/electrolytic manganese dioxide through leaching manganese oxide by sulfur dioxide |
| abstract | The invention discloses a method for preparing electrolytic manganese/electrolytic manganese dioxide through leaching manganese oxide by sulfur dioxide. The method mainly comprises the processing steps of: preparing manganese oxide ore pulp with the concentration of Mn<2+> in electrolyte being 35-40 g/L and the manganese leaching rate of manganese oxide being not less than 90%; sending the manganese oxide ore pulp, sulfur dioxide gas and ozone into an absorption and leaching reactor and performing absorption and leaching reaction after gas-liquid-solid phases are fully contacted; discharging the pulp passing through the absorption and leaching reactor into a purification and decontamination reactor, adding alkali liquor into leaching solution to keep the pH value of the leaching solution to range from 5.0 to 5.5, and pumping ozone to perform purification and decontamination reaction; and performing solid-liquid separation after the purification and decontamination reaction, and sending an obtained liquid phase to an electrolysis procedure to be subjected to electrolysis so as to obtain an electrolytic manganese product or an electrolytic manganese dioxide product at a cathode, wherein the anode liquid is returned to the fourth step to serve as washing liquid or returned to the first step to be used for preparing the manganese oxide ore pulp. The method has the advantages that the quality of manganese sulfate mother liquid is good, the procedure of purification and decontamination is simplified, the closed cycle of the anode liquid is realized, the economic benefit is remarkable and high, and the like. |
